It would be 62.5, I am pretty sure
Answer:
You would need 9/4 or 2 1/4 gallons of paint
Step-by-step explanation:
You would need 2 1/4 gallon of paint because if 1/3 of the room takes 1/4 paint, then 3/4 would finish a room, multiply the three by three for three rooms and there you have 9/4 or 2 1/4 gallons
Step-by-step explanation:
2w+3(2w)=30
8w=30
w=3.75
l=11.25
Answer:
a, 20 side polygond b, the sum of the interior angles is 162°
Answer: $34.65
Step-by-step explanation:
Hi, to answer this question we have to calculate the area of the circular garden
Area of a circle = π r^2
We have the diameter = 20 ft
Diameter = 2radius
Replacing with the value given
20 = 2r
20/2 = r
r = 10 feet
Back with the area formula
A = π r^2
A= π 10^2
A = 314.16 ft2
Since each bag if mulch can cover 50 ft2, we have to divide the area of the garden by the amount of square feet that each bag can cover, to obtain the number of bags
314.16 /50 = 6.28 bags = 7 bags (since the store only sells whole bags)
Finally we have to multiply the price of each bag by the number of bags needed.
7x 4.95 =$34.65
