To find the average of numbers you have to add all the numbers and divide by the number of numbers. *confusing*
25 + 25.4 + 25.35 + 26.1 = 101.85
101.85 ÷ 4 = 25.4625

Answer:
Dilation factor = 0.75.
Step-by-step explanation:
One point on the xy-plane is (-24,-12). The transformation is the dilation which is done on the point and the image is given by (-18,-9). Dilation changes the size of the shape according to the dilation factor. If the original x-coordinate is -24, then the image will be calculated by multiplying the original point with the dilation factor. Therefore, -18= -24 * k, where k is the unknown dilation factor. Simply solve the equation for k.
24k = 18.
k = 18/24 = 3/4 = 0.75.
Similarly, 12k = 9. k = 9/12 = 3/4 = 0.75.
So the point (-24,-12) dilated by k=0.75 to get to (-18,-9)!!!
Answer:
Step-by-step explanation:
first the parenthesis
3^4/3^0=3^4
anything raised to the power of 0 is 1
(3^4)^2=3^8 you multiply the powers
3^-6 * 3^8= 3^(-6+8)=3^2
The choices are not attached but we can solve the problem from the given information
Answer:
The expression can be used to find h is 
The height of the cone is 
cm
Step-by-step explanation:
The formula of the volume of the cone is V = 
π r² h, where
- r is the radius of its base
- h is the height of it
Let us find the height of the cone from the formula of its volume
∵ V = π r² h
- Multiply both sides by 3
∴ 3 V = π r² h
- Divide both sides by π r²
∴ 
- Switch the two sides
∴
The expression can be used to find h is
∵ The radius of the cone is 7 cm
∴ r = 7
∵ The volume of the cone is 147 cm³
∴ V = 147
- Substitute them in the expression of the height to find it
∵ 
∴ h = cm
The height of the cone is cm
