Step-by-step explanation:
The formula of a surface area of a cylinder:
r - radius
H - height
We have r = 40mm and H = 50mm. Substitute:
The value of c in the parallelogram is 45
<h3>How to determine the value of c?</h3>
From the question, we have the following parameters:
- Parallelogram PARL is similar to parallelogram WXYZ.
- AP = 15, PL = 25, and WZ= 75
To calculate the value of c, we make use of the following equivalent ratio.
AP : PL = XW : WZ
Substitute the known values in the above equation
15 : 25 = c : 75
Express the above equivalent ratio as fractions
15/25 = c/75
Multiply both sides of the equation by 75
75 * 15/25 = c/75 * 75
Evaluate the product
75 * 15/25 = c
Evaluate the product
1125/25 = c
Evaluate the quotient
45 = c
Rewrite the equation as
c = 45
Hence, the value of c in the parallelogram is 45

Answer:
the slope shows that the average rating increased 0.4 points per month
Step-by-step explanation:
the equation is written in slope-intercept form. aka y=mx+b. m represents the slope and b represents the y-intercept. therefore in the equation y=0.4x+3 the slope is 0.4

Step-by-step explanation:
A triangle ABC with vertices A(0, 0), B(0, 4), and C(6, 0) is dilated to form a triangle A'B'C' with vertices A′(0, 0), B′(0, 10), and C′(15, 0). If the center of dilation is point A or A' (the origin), then
Since
- AB=4;
- A'B'=10;
- AC=6;
- A'C'=15,
then the scale factor of the dilation is
