Answer:
Pual needs 3 gallons
Step-by-step explanation:
∵ The dimensions of the four walls are:
25 × 8 , 30 × 8 , 25 × 8 , 30 × 8
∴ The area of painting = 2(25 × 8) + 2(30 × 8)
= 400 + 480 = 880 square feet
∵ each gallon paint 400 square feet
∴ The number of gallons = 880/400 = 2.2, so he needs 3 gallons
75, 76, 80, 83, 84, 85, 89, 91, 94, 94
The median is 84.5
You add the two middle numbers (84, 85) and divide by 2.
Answer:
c=l/--a^2+b^2=l/--45^2+20^2≈49.24429
Step-by-step explanation:
l/-- mean square root
^ means squared/ exponent
(5 / 3) * PI = 300 degrees
Sector area = (central angle (degrees) / 360) * PI * radius^2
Sector area = (300 / 360) * 3.14 * 36
Sector area = (5/6) * 3.14 * 36
Sector area = 30 * 3.14
Sector area = 94.2 square feet
