Answer:
16,507.38
Step-by-step explanation:
The equation for this would be 8600(1 + 0725/52)^52*9
9 is the years, 52 is the compounded weekly, and 8600 is the initial amount.
Solving the equation, we get:

Solve this using factoring, what are the two x’s?
Note : a × b = 0 ==》 a = 0 Or b = 0
_________________________________
( 2x - 7 )( 5x + 75 ) = 0
2x - 7 = 0 ===》 2x = 7 ===》 x = 7 / 2
===》 x = 3.5
Or
5x + 75 = 0 ==》 5x = - 75 ==》 x = - 75 / 5
==》x = - 15
Step-by-step explanation:
(2x-7)(5x+75)=0
2x(5x+75) -7 (5x+75)=0
10x^2 + 150x - 35x - 525 =0
10x^2 + 115x - 525 =0
5(2x^2 + 23x - 105 ) =0
2x^2 +30x-7x - 105 =0
2x ( x + 15 ) -7 ( x + 15) = 0
(2x-7) (x + 15) =0
so, 2x-7=0 and x+15 =0
x = 7/2 and x = -15

x+10=2x-4 what does x=
Answer:
x = 14
Step-by-step explanation:
x + 10 = 2x - 4
x + 10 - 10 = 2x - 4 - 10
x = 2x - 14
x - 2x = 2x - 2x - 14
- x = - 14
- x ÷ - 1 = - 14 ÷ - 1
x = 14
In cm, the lengths of the sides of a rectangle are 30 and 24. Find the nearest degree the measure of the angle formed by a diagnol and one of the longer sides
Answer:
38.42cm
Step-by-step explanation:
Given that the length of the sides of a rectangle are 30 cm and 24 cm.
The length of the diagonal can be obtiaed using Pythagoras rule
Length of the diagonal = hypotenus
Hypotenus = sqrt(opposite ² + adjacent ²)
Opposite and adjacent sides are 30cm and 24 cm
Hypotenus = sqrt(30² + 24²)
Hypotenus = sqrt(900 + 576)
Hypotenus = sqrt(1476)
Hypotenus = 38.419
Length of diagonal = 38.42cm
Answer:
find the size of angle O to the nearest degree
You have total coins for a total of $. . You only have quarters and dimes. Let represent the number of quarters and represent the number of dimes.
Answer:
[tex]Quarters = 41[/tex]
[tex]Dimes = 18[/tex]
Step-by-step explanation:
Given
[tex]Coins = 59[/tex]
[tex]Worth = \$12.05[/tex]
[tex]d = dimes[/tex]
[tex]q = quarters[/tex]
Required
The number of each coin
The total coins can be represented as:
[tex]d + q = 59[/tex]
[tex]1\ quarter = \$0.25 \\ 1\ dime = \$0.10[/tex]
So, the worth of the coin is:
[tex]0.25q + 0.10d = 12.05[/tex]
The equations to solve are:
[tex]0.25q + 0.10d = 12.05[/tex]
[tex]d + q = 59[/tex]
Make d the subject in: [tex]d + q = 59[/tex]
[tex]d =59 - q[/tex]
Substitute [tex]d =59 - q[/tex] in [tex]0.25q + 0.10d = 12.05[/tex]
[tex]0.25q + 0.10(59 - q) = 12.05[/tex]
[tex]0.25q + 5.9 - 0.10q = 12.05[/tex]
Collect like terms
[tex]0.25q - 0.10q = 12.05 - 5.9[/tex]
[tex]0.15q = 6.15[/tex]
Solve for q
[tex]q=\frac{6.15}{0.15}[/tex]
[tex]q=41[/tex]
Substitute [tex]q=41[/tex] in [tex]d =59 - q[/tex]
[tex]d = 59 - 41[/tex]
[tex]d = 18[/tex]
So:
[tex]Quarters = 41[/tex]
[tex]Dimes = 18[/tex]

7. A car drives 50 miles in the first hour on the road, 70 miles during the 2nd hour and 10 miles for 1/2 hour (traffic jam), then 60 miles in the final half hour of the trip. What was the average speed for the entire trip?
Answer:
Step-by-step explanation:
Average Speed = Total Distance / Total Time
Total Distance = 50+ 70 + 10 + 60 = 190 Miles
Total Time = 1 + 1 + 1/2 + 1/2 = 3 hours
Average speed = 190 / 3 = 63.3 mph

Determine whether the conclusion is valid. Explain. You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
Answer: The conclusion is valid
Step-by-step explanation:
Number of students surveyed = 50
Number of students who visited a science museum = 20
Number of students who haven't visited a science museum = 30
Percentage of student that have visited a Science museum:
= 20/50 × 100
= 40%
The conclusion is valid based on the calculation.
when would you solve by elimination?
Answer:
when its a linear equation
Step-by-step explanation:
Answer:
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

What is the sum of the interior angles of the polygon pictured below?
The shape has 9 sides.
Sum of interior angles = (n-2) x 180, where n is the number of sides.
Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
Answer:
Solution :-We have
Side of polygon = 9
So,
By using the formula
(n - 2) × 180
(9 - 2) × 180

Answer: x = 13.4
Step-by-step explanation:
1. Subtract 90 degrees and 33 degrees to get angle X, which is 57 degrees.
2. Using Laws of Sine, plug in the known elements of the triangle:
(16) / (sin(90)) = (x) / (sin(57))
3. Cross multiply, this will leave 16sin(57) = xsin(90)
4. Divide sin(90) to the other side, leaving x = (16sin(57)) / (sin(90))
5. Plug this into a calculator and your final answer should be 13.4

Choose 1 answer:
(Choice A)
4.5 units
(Choice B)
5.4 units
(Choice C)
9.1 units
(Choice D)
10.9 units
Answer:
The answer is B 5.4 units
Step-by-step explanation:
The approximate value of PQ in the right angle triangle is 5.4 units.
Right angle triangleA right angle triangle has one of its angles as 90 degrees. Therefore, the sides can be found by trigonometric ratios.
Hence,
sin 50 = opposite / hypotenuse
sin 50 = PQ / 7
cross multiply
PQ = 7 sin 50°
PQ = 7 × 0.76604444311
PQ = 5.36231110183

He price of a computer component at the QRCC bookstore is decreasing at a rate of 2.25% per year. Decide whether this decrease is linear or exponential.
Answer:
The decrease is exponential.
Step-by-step explanation:
An exponential decrease is something like:
f(x) = A*(r)^x with 0 < r < 1
A linear decrease is something like:
g(x) = -a*x + b with a > 0
First ai general formula.
If you have a quantity Q, decreased by an X%, the new quantity will be:
New Quantity = Q - Q*(X%/100%)
Now let's look at the question:
Suppose that the original price of the computer component is K
And the price as a function of the year is P(y)
Then we know that, in the year zero, the price is K.
P(0) = K
One year after, the price decreases by 2.25%
Then:
P(1) = K - K*(2.25%/100%) = K*(1 - 0.0225)
After another year, we will have another decrease of 2.25%
Then:
P(2) = K*(1 - 0.0225) - K*(1 - 0.0225)*(2.25%/100%)
P(2) = K*(1 - 0.0225)*(1 - 0.0225) = K*(1 - 0.0225)^2
We already can see the pattern, we can expect that in the year y, the price of the component will be:
P(y) = K*(1 - 0.0225)^y
This clearly is an exponential decrease.
