You get a job as a nurse. Your salary for the first year is $33,500. You will
receive a 1.5% increase every year. If you could save your entire salary, how
much money would you have in 4 years? Round to the nearest dollar.
Answer:
Step-by-step explanation:
Assuming that your salary is $1, your savings after each year would be:
End of year 1: $1 x 1.015 = $1.015
End of year 2: $1.015 x 1.015 = $1.03023
End of year 3: $1.03023 x 1.015 = $1.04586
End of year 4: $1.04586 x 1.015 = $1.06186
Therefore, after 4 years of saving your entire salary with a 1.5% increase each year, you would have approximately $1.06.

System: 3x - 12y = 2, y = x - 8
Part 2: Classify the system as consistent independent, inconsistent, or coincident. (2 points)
Part 1: Let's solve the system using substitution:
Since y = x - 8, we can substitute this expression for y in the first equation:
3x - 12(x - 8) = 2
Now, we'll solve for x:
3x - 12x + 96 = 2
-9x + 96 = 2
-9x = -94
x = 94/9
Now that we have the value of x, we can substitute it back into y = x - 8 to find the value of y:
y = (94/9) - 8
y = (94 - 72)/9
y = 22/9
So, the solution to the system is x = 94/9 and y = 22/9.

In nop, the measure of zp=90°, the measure of zn=39, and pn = 72 feet. find the length of op to the nearest tenth of a foot?
The length of OP to the nearest tenth of a foot is approximately 41.5 feet
To find the length of OP, we can use the Pythagorean theorem since we have a right triangle.
OP^2 = PN^2 - ON^2
First, we need to find ON using the trigonometric ratio of tangent.
tan(39) = ON/PN
ON = PN * tan(39)
ON = 72 * tan(39)
ON ≈ 53.4 feet

the figure is the base
The Volume and the surface area of the given figure are 87 in³ and 83 in²
To find the volume of the figure, we need to split it into smaller rectangular parts and find the volume of each part separately. From the given measurements, we can see that the figure consists of three rectangular parts:
The volume of each part can be found using the formula:
Volume = length x width x height
Part 1: A rectangular prism with dimensions 3 in x 3 in x 1 in
Volume = 3 in x 3 in x 1 in
Volume = 9 in³
Part 2: A rectangular prism with dimensions 1 in x 6 in x 7 in
Volume = 1 in x 6 in x 7 in
Volume = 42 in³
Part 3: A rectangular prism with dimensions 6 in x 6 in x 1 in
Volume = 6 in x 6 in x 1 in
Volume = 36 in³
Total Volume:
The total volume of the piecewise rectangular figure is the sum of the volumes of each part:
Total Volume = Volume of Part 1 + Volume of Part 2 + Volume of Part 3
= 9 in³ + 42 in³ + 36 in³
= 87 in³
To find the surface area of the figure, we need to find the area of each face and add them up. The figure has 6 rectangular faces, and the area of each face can be found using the formula:
Area = length x width
Part 1:
Top and Bottom faces:
Area = 3 in x 3 in
Area = 9 in²
Side faces:
Area = 3 in x 1 in
Area = 3 in² (x2)
Total Area of Part 1:
Total Area = 9 in² + (3 in² x 2)
= 15 in²
Part 2:
Top and Bottom faces:
Area = 1 in x 6 in
Area = 6 in²
Side faces:
Area = 1 in x 7 in
Area = 7 in² (x2)
Total Area of Part 2:
Total Area = 6 in² + (7 in² x 2)
= 20 in²
Part 3:
Top and Bottom faces:
Area = 6 in x 6 in
Area = 36 in²
Side faces:
Area = 6 in x 1 in
Area = 6 in² (x2)
Total Area of Part 3:
Total Area = 36 in² + (6 in² x 2)
= 48 in²
Total Surface Area:
The total surface area of the figure is the sum of the areas of all its faces:
Total Surface Area = Total Area of Part 1 + Total Area of Part 2 + Total Area of Part 3
= 15 in² + 20 in² + 48 in²
= 83 in²

Last season joao scored a goal in 3/5 or 60% of the soccer games. use this experimental probability to determine the number of games he will score a goal this season, if he plays in 10 games
If Joao scored a goal in 60% of the soccer games last season, then we can expect him to score a goal in about 60% of the games he plays this season.
So, if Joao plays in 10 games this season, we can estimate that he will score a goal in approximately 60% of those games.
To calculate the actual number of games he is expected to score a goal in, we can use the formula:
Expected number of goals = Total number of games x Probability of scoring a goal
Plugging in the numbers, we get:
Expected number of goals = 10 x 0.6 = 6
Therefore, based on the experimental probability from last season, we can estimate that Joao will score a goal in around 6 games out of the 10 he plays this season.

A farmer plans to plant two crops. A and B. The cost of cultivating Crop A is $30/acre, whereas the cost of cultivating Crop B is 560/acre. The farmer has a maximum of $7400 available for and cultivation. Each acre of Crop Arequires 20 labor hours, and each acre of Crop Brequires 25 tabor hours. The farmer has a maximum of 3400 labor hours available. If she expects to make a profit of $160/acre on Crop Aand $220/acre on Crop B, how many acres of each crop, and respectively should she plant to maximize her profit in dollars?
The farmer should plant 116 acres of Crop A and 104 acres of Crop B to maximize her profit, which would be $41,840.
To maximize profit, the farmer should plant the crop with the higher profit per acre until she runs out of money or labor hours.
Let x be the number of acres of Crop A to be planted, and y be the number of acres of Crop B to be planted.
The objective function (profit) is: Profit = 160x + 220y
The constraints are: Cost constraint: 30x + 560y ≤ 7400 Labor hour constraint: 20x + 25y ≤ 3400
To solve this problem using linear programming, we can use a graphing calculator or software.
However, we can also solve it manually by finding the corner points of the feasible region (the area that satisfies all constraints) and evaluating the objective function at each point. The corner points are: (0, 296/5) (116, 104) (170, 56) (222/5, 0)
Evaluating the objective function at each point, we get: (0, 296/5):
Profit = 0 + 160(296/5) = 9472 (116, 104):
Profit = 160(116) + 220(104) = 41840 (170, 56):
Profit = 160(170) + 220(56) = 38480 (222/5, 0):
Profit = 160(222/5) + 0 = 7104

What is the measure of the smallest angle of the triangle in degrees?
A 47°
B 26°
C 107°
D 23°
Answer: B
Step-by-step explanation:
x + 3 + 5x - 8 + 2x + 1 = 180
8x - 4 = 180
8x = 184
x = 23
23 + 3 = 26, 5(23) - 8 = 107, 2(23) + 1 = 47
the smallest is 26
Solve the inequalities 1/3(2x-1)≤1-2/5(2-3x)
The solution to the inequality is x ≥ -1.
We solve the inequality 1/3(2x-1)≤1-2/5(2-3x).
Let's go step by step:
Begin by distributing the fractions to the terms inside the parentheses:
(1/3 * 2x) - (1/3 * 1) ≤ 1 - (2/5 * 2) + (2/5 * 3x)
(2x/3) - (1/3) ≤ 1 - (4/5) + (6x/5)
Combine like terms on each side of the inequality:
(2x - 1)/3 ≤ (1 - 4/5) + 6x/5
(2x - 1)/3 ≤ (1/5) + 6x/5.
To eliminate the fractions, find a common denominator, which in this case is 15.
Multiply each term by 15:
15 * (2x - 1)/3 ≤ 15 * (1/5) + 15 * 6x/5
5(2x - 1) ≤ 3 + 18x
Distribute and simplify:
10x - 5 ≤ 3 + 18x
Move the variables to one side and constants to the other side:
10x - 18x ≤ 3 + 5
-8x ≤ 8
Divide both sides by -8 (remember to flip the inequality sign since we are dividing by a negative number):
x ≥ -1.

The value of the book after 11 years is $101.38. Therefore, the correct option is C.
Find the value of the book after 11 years with an initial value of $258 and a decrease rate of 8% per year as follows.
1. Convert the percentage decrease to a decimal by dividing it by 100:
8% / 100 = 0.08
2. Subtract the decimal from 1 to represent the remaining value each year:
1 - 0.08 = 0.92
3. Raise the remaining value (0.92) to the power of the number of years (11):
0.92^11 ≈ 0.39197
4. Multiply the initial value of the book ($258) by the calculated remaining value (0.39197):
$258 × 0.39197 ≈ $101.07
Therefore, after 11 years, the value of the book is approximately $101.07, which is closest to option C, $101.38.

A) identity the distribution with the parameters B) the 8th success occurs on the 17th spin. C) the 13th success occurs between the 31st and the 34th spin. PLEASE SOMEONE HELP <3
A) The distribution is a negative binomial distribution with parameters r and p.
B) The probability that the 8th success occurs on the 17th spin is approximately 0.8%.
C) The probability that the 13th success occurs between the 31st and 34th spin is approximately 0.6%.
A) The distribution is a negative binomial distribution with parameters r = number of successes (in this case, r = 1 since we are only interested in the first success), and p = probability of success (landing in a green slot).
B) To find the probability that the 8th success occurs on the 17th spin, we use the formula for the negative binomial distribution:
P(X = k) = (k-1)C(r-1) * [tex]p^r[/tex] * [tex](1-p)^{(k-r)[/tex]
where X is the number of spins until the Rth success, k is the number of spins, and C(n,r) is the binomial coefficient (n choose r).
In this case, we want to find P(X = 17) when r = 8 and p = 2/38 (since there are 2 green slots out of 38 total slots):
P(X = 17) = (16 C 7) * (2/38)⁸ * (36/38)⁹
≈ 0.008 or 0.8%
So the probability that the 8th success occurs on the 17th spin is approximately 0.8%.
C) To find the probability that the 13th success occurs between the 31st and 34th spin, we need to find the probability of getting exactly 12 successes in the first 30 spins, followed by a success on one of the next 4 spins (31st, 32nd, 33rd, or 34th).
P(31 ≤ X ≤ 34) = P(X ≤ 34) - P(X ≤ 30)

Sam puts a cash deposit of $8,000 on a used car. the bank is charging sam an interest rate of 4.75% per year. how much interest will he pay to the bank at the end of 5 years?
At the end of 5 years, Sam will have paid $1,900 in interest to the bank. This calculation assumes that the interest rate remains constant and is applied on a simple basis, rather than being compounded over the 5-year period.
Sam makes a cash deposit of $8,000 on a used car and is charged an interest rate of 4.75% per year by the bank. To calculate the interest he will pay at the end of 5 years, we can use the formula for simple interest, which is I = P × R × T, where I is the interest, P is the principal (the initial deposit), R is the interest rate, and T is the time in years.
In this case, P = $8,000, R = 4.75% (or 0.0475 in decimal form), and T = 5 years. Plugging these values into the formula, we get:
I = $8,000 × 0.0475 × 5
I = $1,900

Sam will pay $1,900 in interest to the bank at the end of 5 years.
How to find interest rate?The interest rate is 4.75% per year, which can be written as 0.0475 as a decimal. The amount of interest that Sam will pay after 5 years can be calculated using the simple interest formula:
Interest = Principal x Rate x Time
where Principal is the initial deposit, Rate is the interest rate, and Time is the length of time the interest is charged for.
In this case, the Principal is $8,000, the Rate is 0.0475, and the Time is 5 years. Plugging these values into the formula, we get:
Interest = $8,000 x 0.0475 x 5
Interest = $1,900
Therefore, Sam will pay $1,900 in interest to the bank at the end of 5 years.

Dorothy made a dot plot showing the heights of her plants in her garden. write a proportion to find the percentage of plants that are exactly 13cm tall.
2/9 = x/100
13/100 = x/100
2/12 = x/100
2/13 = x/20
right answer please.
To find the percentage of plants that are exactly 13cm tall using a proportion, you need to first identify the number of plants that are 13cm tall and the total number of plants. Based on your question, let's assume that 2 out of 9 plants are exactly 13cm tall.
Now, set up a proportion with the given information:
(number of plants 13cm tall) / (total number of plants) = (x) / (100)
In this case, the proportion is:
2/9 = x/100
To solve for x, cross-multiply:
2 * 100 = 9 * x
200 = 9x
Now, divide both sides by 9:
x = 200 / 9
x ≈ 22.22
So, approximately 22.22% of the plants in Dorothy's garden are exactly 13cm tall.

The parabolas y=x^2 and y=-x^2-4x+6 are graphed below. What are they-values of the solutions to this system of equations
Answer:
y = 2.25
Step-by-step explanation:
The solutions are the points of intersection of the 2 graphs.
The function f is any. Express D as a type II region. Express
D as a type I region and draw D.
According to the given function, D is a type I region that can be expressed as D = {(x,y) | 0 ≤ y ≤ f(x), 2y ≤ x ≤ 2}.
Consider the given double integral ∫∫f(x, y) dA= ∫⁴₀∫²ₓ f(x, y) dx dy, where f is any function. Here, we need to express the region D as a type II region and then as a type I region.
A type II region is a region in the xy-plane that is bounded above and below by two curves and bounded on the left and right by two vertical lines. In other words, a type II region is a region that can be expressed as D = {(x,y) | a ≤ x ≤ b, g(x) ≤ y ≤ h(x)}, where a, b, g(x), and h(x) are functions.
To express D as a type II region, we first note that the given integral has the limits of integration as ∫⁴₀ and ∫²ₓ, which implies that the region D is bounded on the left by the y-axis and on the bottom by the x-axis. Also, the region D is bounded on the right by the vertical line x = 2x, and on the top by the curve y = f(x).
Therefore, we can express D as D = {(x,y) | 0 ≤ x ≤ 2, 0 ≤ y ≤ f(x)}, which is of the form D = {(x,y) | a ≤ x ≤ b, g(x) ≤ y ≤ h(x)}. Hence, D is a type II region.
Next, we need to express D as a type I region. A type I region is a region in the xy-plane that is bounded on the left and right by two curves and bounded above and below by two horizontal lines. In other words, a type I region is a region that can be expressed as D = {(x,y) | c ≤ y ≤ d, p(y) ≤ x ≤ q(y)}, where c, d, p(y), and q(y) are functions.
To express D as a type I region, we need to find the equations of the curves that bound the region D. From the given integral, we know that the region D is bounded on the left by the y-axis and on the bottom by the curve y = 0. Also, the region D is bounded on the top by the curve y = f(x) and on the right by the vertical line x = 2.
Therefore, we can express D as D = {(x,y) | 0 ≤ y ≤ f(x), x/2 ≤ y}, which can be rewritten as D = {(x,y) | 0 ≤ y ≤ f(x), 2y ≤ x ≤ 2}, where 2y ≤ x ≤ 2 corresponds to the line x = 2y.

Which of the following is a typical characteristic of debit cards? (1 point)
O Your bank may charge you a very large fee each time you use one.
O When you buy something from a store, you may be offered a discount if you open one with the store.
O They usually charge a lower interest rate than credit cards.
They are tied directly to your bank account.
A typical characteristic of debit cards is expressed by option D, they are tied directly to your bank account, since money has to be deducted for a purchase to be made.
How debit cards functionWhen you use a debit card to make a purchase, the money is deducted directly from your bank account. Debit cards do not typically charge interest like credit cards do, so C is not correct.
A is also not correct since most banks do not charge a fee for using a debit card, although some may charge fees for using an out-of-network ATM or overdraft fees if you spend more than you have in your account. B is not a typical characteristic of debit cards either, as there is generally no connection between a store's loyalty program or discounts and using a debit card for payment.
Therefore, it is possible to conclude that debit cards have option D as their characteristic. Since they require money in the bank to make the purchase, they are connected to one's account.

When Julie jogs she burns 255 calories I'm 15 minutes and 340 calories in 20 minutes. Which equation represents how many calories she burn pre minute?
The calories she burns per minute is 17 cal
We are given that the total calories that are burnt in 15 minutes and 20 minutes are 255 and 340 respectively.
We can use the equation
total calorie burnt = time (in minutes) * calorie burnt in one minute
here we know the total calorie that is burnt and the time, we can substitute the calorie that is burnt in a single minute with 'n'.
we can say that :
255 = 15 * x
x=255/15
x= 17.
The total calorie burn per minute is 17.
now for the verification, we know that if the total calorie burn per minute is 17 it should satisfy both the equation.
So, 340 = 20*x
340=20* 17
340 = 340
Thus it satisfies both equations.
Hence the calorie burnt per minute = 17
