Answer:
Number of movies for equal wage = 20
Step-by-step explanation:
Assume;
Number of movies for equal wage = x
So,
75 + 2x = 5.75 x
3.75 x = 75
x = 75 / 3.75
x = 20
So,
Number of movies for equal wage = 20

The radius of a spherical ball is increasing at a rate of 2 cm/min. At exactly what rate (in cm2/min) is the surface area of the ball increasing when the radius is 9 cm?
Answer:
9th min?
Step-by-step explanation:
lol sorry im set 4 maths
144π cm²/min is the surface area of the ball increasing when the radius is 9 cm.
What is Surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given,
Radius of a spherical ball is increasing at a rate of 2 cm/min.
We need to find exactly what rate (in cm2/min) is the surface area of the ball increasing when the radius is 9 cm
S = surface area at time t, and r = radius at time t
r=9cm
dr/dt = 2 cm/min
S = 4πr²
Differentiate with respect to t
ds/dt=2.4πrdr/dt
=8πr(2)
=16πr
=16π(9cm)
=144π cm²/min
Hence 144π cm²/min is the surface area of the ball increasing when the radius is 9 cm.

The true statements about 15 ≥ 22 + x are
x ≤ -7, the graph has a closed circle and -7 is part of the solution.
How to determine the true statements?The inequality is given as
15 ≥ 22 + x
Subtract 22 from both sides
-7 ≥ x
Rewrite as:
x ≤ -7
The ≤ implies that the solution is a closed circle, and the other true statement is: (e) -7 is part of the solution.

Ms. Andrew currently earns $4,225 per month. She will receive a 17% increase in pay beginning next month. How much can she expect to earn next month, to the nearest cent?
Ms. Andrew can expect to earn $4,942.25 next month, to the nearest cent.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."
To calculate Ms. Andrew's new monthly salary, we need to add 17% of her current salary to her current salary:
New salary = Current salary + 17% of current salary
New salary = $4,225 + 0.17($4,225)
New salary = $4,225 + $717.25
New salary = $4,942.25
Therefore, Ms. Andrew can expect to earn $4,942.25 next month, to the nearest cent.

The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing when the diameter is 100 mm?
Answer:
157,143 mm/s
Step-by-step explanation:
Formula for the volume of a sphere is;
V = 4/3 * pi * r^3
dv/dr = 4 pi r^2
dv/dt = dv/dr * dr/dt
dr/dt = 5 mm/s
dr/dt = 4 * pi * r^2
r = d/2 = 100/2 = 50 mm
dr/dt = 4 * 22/7 * 50^2 = 220,000/7
dv/dr = 220,000/7 * 5 = 157,142.8571428571
Approximately 157,143 mm/s

what is 168 divided by 12 but using estimation
Answer:
14
Step-by-step explanation:
The division of the number 198 by 12 is approximately 17.
A mathematical process known as division can be used to divide a sum of money into equal parts or to calculate how many times one number can be found inside another.
A quotient is produced as a result of dividing a dividend (the number being divided) by a divisor (the number by which the dividend is divided).
To estimate the division of 168 by 12, we can use rounding to simplify the calculation.
Round the numbers to a more manageable value. In this case, we can round 168 to 170 and 12 to 10.
Divide the rounded numbers. 170 divided by 10 is equal to 17.
Therefore, an estimated answer to the division of 168 by 12 is approximately 17.

In general, how do the slopes of line segments in the image compare with the slopes of corresponding line segments in the preimage? What effect does the scale factor of the dilation have on the slopes, if any?
Answer:
The slopes of the line segments are the same before and after dilation. The value of the scale factor n does not affect the slopes in the image.
Step-by-step explanation:
Plato simple answer
The slopes of the line are the same before and after dilation. The value of the scale factor n does not affect the slopes in the image.
How does dilation works?Dilation of a figure will leave its sides get scaled (multiplied) by same number.
Dilation if, is from the center of the rectangle, then distance of all the points of the rectangle from its center will get scaled by that dilation factor.
Slope:
We know that the slope is the ratio of change in y-value and change in x-value.
So, after dilation

Length of line:
The length of line =x
