STEP 1:
You need to find the area of the circular pad.
Circle Area= πr^2
we need the radius which is half of the diameter given
=π(50÷2)^2
=(3.14)(25)^2
=(3.14)(625)
=1,963.495 ft^2 total area
STEP 2:
Find how much paint is needed by dividing a can's coverage into what's needed.
=1963.495 ÷ 200
=9.817
=10 cans are needed (because you cannot buy a part of a can, you need to round up)
ANSWER: 10 cans are needed
Hope this helps! :)
You add 2 to 8 to get 10. I decided on that because that's just what you do for simple addition. ;)
Answer:
B & C
Step-by-step explanation:
A proportional relationship has a proportionality constant (constant rate of change) and and must cross through the origin (or begin at (0,0). This means it's y-intercept is 0. Each of the options is a linear function. All of the functions have a constant rate of change. Only one as b=0 or 0 as the y-intercept.
B) y=4x has a constant of 4 and passes through the origin.
C) y=7x has a constant of 7 and passes through the origin.
2x + 3y = 1470
Minus 2x from both sides gives
3y = 1470 - 2x
divide through by 3
y = 490 - 2/3x
