Jillene spends $240 on a new business the first month. If she spends 24% more each month, approximately how much will she spend (total sum) in 6 months?
Answer:
Jillene will spend $345.60 in 6 months.
Step-by-step explanation:
To find the answer we will turn 24% into a decimal. 24% ÷ 100 = 0.24. Now multiply 0.24 by $240 and we get $57.60. Because we are trying to find how much Jillene will spend in 6 months, we will multiply $57.60 by 6, which is $345.60. Therefore, $345.60 is our answer.
Answer: $1785.60
Step-by-step explanation:
240 x 6 = 1440
240 x 0.24 = 57.6
57.6 x 6 = 345.6
1440 + 345.6 = 1785.60
Final Answer: $1785.60
Write the equation of the line that passes through the points (-1, -2) and (5, -4).
Answer:
y = -1/3x - 7/3
Step-by-step explanation:
To find the slope, you have to plug the values into the slope formula.
y2 - y1/ x2 - x1
-4 - (-2) / 5 - (-1)
-1/3
Now to find the y-intercept, plug in one of the coordinates into the equation.
y = -1/3x + b
-2 = -1/3(-1) +b
-2 = 1/3 + b
-7/3 = b
The equation is y = -1/3x - 7/3.
The Solution is Y = - ( 1 / 3 )X - 7 / 3 where points are ( 5 , - 4) and ( - 1 , - 2) that passes through a straight line. Y = MX + C is the Formula for Straight line equation.
As per given problem, M is Slope
M = (Y2 - Y1) / (X2 - X1)
M = (- 4 - (- 2)) / ( 5 - (- 1))
M = - (1 / 3)
Now, Line becomes
- 2 = - ( 1 / 3) x (- 1)+ C
- 2 = 1 / 3 + C
C = - (7 / 3)
So, Solution: Y = - (1 / 3)X - (7 / 3)

Round your answer to the nearest tenth of a cubic inch.
Answer:
33.1in³
Step-by-step explanation:
Volume of the square based pyramid = BH/3
B is the base area
H is the height
Base area = L²
Base area = 4.7²
Base area = 22.09 square inches
Height = 4.5in
Get the volume
Volume of the pyramid = 22.09*4.5/3
Volume of the pyramid = 22.09 * 1.5
Volume of the pyramid = 33.135in³
Hence the volume of the square based pyramid to the nearest tenth of a cubic inch is 33.1in³

certain plant grows 1 3 4 inches every week. How long will it take the plant to grow 6 1 4 inches? How long will it take the plant to grow 6 1 4 inches?
Answer:
it will take around 4.5 weeks
Step-by-step explanation:
614 divided by 134 will give you 4.582
Answer:
4.6 weeks
Step-by-step explanation:
In the question, it stated that the plant grows at the rate of 134 inches per week. And we can get the proportion:
[tex]\frac{1 week}{134 inches}[/tex]
Now, if you want to get the number of weeks it takes to grow 614 inches, set up the proportion
[tex]\frac{x }{614 inches}[/tex]
with x representing the number of weeks we are trying to find.
Since the two fractions are proprtional - we assume that the plant will always grow at the same rate, then we can state:
[tex]\frac{x }{614 inches}[/tex] = [tex]\frac{1 week}{134 inches}[/tex]
Now, cross multiply and simplify:
134x = 614
x = 614/134
x = 4.6 (Weeks)

The average of 9 scores is x. If the tenth score is 36 points more than x, by how many points will the tenth score raise the average?
Answer:
3.6
Step-by-step explanation:
The average of 9 scores is x.
average = (sum of scores)/(number of scores)
x = (sum of scores)/9
sum of scores = 9x
The sum of the 9 scores is 9x.
The tenth score is 36 more than x, so it is x + 36.
The sum of the 10 scores is 9x + x + 36 = 10x + 36.
The average of the 10 scores is (10x + 36)/10 = x + 3.6
The difference of averages is
x + 3.6 - x = 3.6
PLEASE HELP ASAP THANK YOUU: A unicycle wheel makes five rotations. The unicycle travels 37.94 feet. Find the diameter of the wheel in inches.
Show your work and write your answer in a sentence.
Answer:
diameter of the wheel = 28.98 in (2 d.p.)
Step-by-step explanation:
Given information:
A unicycle wheel makes five rotationsThe unicycle travels 37.94 feetCircumference of a circle = πd (where d is the diameter)
One rotation of the wheel is equal to the circumference of the wheel.
Therefore, 5 rotations is equal to the sum of 5 circumferences.
To find the diameter of the wheel in feet, equate the expression for 5 circumferences to the total distance traveled and solve for d:
[tex]\begin{aligned}\textsf{5 circumferences} & = \textsf{total distance traveled}\\\implies 5 \pi d & = \sf 37.94\: ft\\d & = \sf \dfrac{37.94}{5 \pi}\\d & = \sf 2.415335416... \:ft \end{aligned}[/tex]
As 1 foot = 12 inches, multiply the found diameter in feet by 12 to calculate the diameter in inches:
[tex]\begin{aligned}d & =2.415335416... \times 12\\\implies d & = \sf 28.98\:\:in\:(2\:d.p.)\end{aligned}[/tex]
Therefore, the diameter of the wheel is 28.98 in (2 d.p.).

The department of natural resources reports that a water supply does not receive a 4-star rating if the fluoride concentration is less than 4%. In this context, what is a Type I error?
Answer:
natural resource department does not receive a 4 star rating
Step-by-step explanation:
The type I error is also known as the 'false positive'.
It means we means we reject or make an error while the condition or the result is actually true. In other words, we can say that we are rejecting the null hypothesis but the hypothesis is actually true in all populations.
A 'false negative' is considered a type II error.
in the context, the hypothesis is concentration of fluoride in water which should be less than 4%. This is true but the department does not a 4 star rating when the concentration is less than 4% on the water supply. So this is the type I error.

If you put $375 into a savings account that pays 6% interest compounded monthly, how much money would you have in your account after 3 years?
How much did you earn in interest?
Answer:
$448.76
$73.76
Step-by-step explanation:
We are to calculate the future value with monthly compounding
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value
R = interest rate
m = number of compounding
N = number of years
$375 x ( 1 + 0.06/12)^12 x 3
$375 x (1.005)^36 = $448.76
Interest earned = future value - amount saved
$448.76 - $375 = $73.76
