Answer:
Number of can needed to paint inside of the circular helicopter pad = 1
Step-by-step explanation:
The circular pad is given to be 50 feet across.
⇒ Circumference of the circular pad = 50 feet
⇒ 2π·r = 50
⇒ π·r = 25
⇒ r = 7.96 feet
Now, Area of the circular pad = π·r²
⇒ Area = 3.14 × 7.96²
⇒ Area = 198.96 square feet
Now, one can of paint covers 200 feet² area of the pad
Hence, 198 feet² area can also be painted by using one can.
Therefore, number of can needed to paint inside of the circular helicopter pad = 1
Answer:
Step-by-step explanation:
Given expression:
2x + 5y = -10
The equation of a straight line is;
y = mx + c
y and x are the coordinates
m is the slope
c is the intercept
Now;
let us write the given expression in slope intercept format;
2x + 5y = -10
5y = -2x - 10
y = 
- 2
So, the slope of the line is

Answer:
927 ft
914 ft
Step-by-step explanation:
The lengths are half the sum plus or minus half the difference:
1841/2 ± 13/2 = {1854/2, 1828/2} = {927, 914} . . . feet
__
Let x represent the shorter length. Then x+13 is the longer length. Their total is ..
x +(x +13) = 1841
2x = 1841 -13
x = (1841 -13)/2 . . . . half the sum minus half the difference
Then the longer length is ...
x+13 = (1841/2) -(13/2) +13
x +13 = (1841/2) +(13/2) . . . . half the sum plus half the difference
