Answer:
$25 a lamp
Step-by-step explanation:
First divide $10,000 by 500 lamps to find how much one of them cost
That is $20 a lamp so then multiply .25 *20 or 1/4 *20
you get 5 than add 20 +5=25
With this function you are given 2 x's and all we have to do is plug those X's into the function so
f(-1)=4*7^-1
7^-1 is 1/7
times 4 = 4/7
f(2)=4*7^2
7^2=49 *4 = 196
Answer:
36/100
Step-by-step explanation:
3/4 * 12/25 = 36/100
multiply the 2 numerators together, then multiple the 2 denominators together.
hope this helps
Answer:
Step-by-step explanation:
The lateral surface area of a cone is given by 
, where 
is the radius of the base of the cone and 
is the cone's slant height.
Solving for :
*Note: It is implied that the surface area of 200 pi square inches is lateral surface area and not total surface area, because it is impossible to obtain a total surface area of 200 pi with a radius of 10 inches.
Step-by-step explanation:
are Supplementary, because they form linear pair angle.
