Let:
x=width
8x=length
P=2l+2w
126=2x + 2(8x)
126=2x+16x
18x=126
x=7

hope this helps!!
The area available to the goat is 3/4 of a circle with 6 ft radius plus 2/4 of a circle with 3 ft radius.
A = (3/4)π*(6 ft)² + (1/2)π*(3 ft)²
= π*((3/4)*36 +(1/2)*9) ft²
= 31.5π ft² ≈ 98.96 ft²
The goat can roam over an area of about 99 ft².
Answer:
She used 6.825 pints of withe paint to paint her bedroom walls
Step-by-step explanation:
We know Cathy used 9.1 pints of paint and 1/4 is blue.
first we have to calculate the white paint, we are going to calculate it by subtracting 1/4 of the total paint
1 - 1/4 = 4/4 - 1/4 = 3/4
Now that we know that 3/4 of the total paint is white, we have to multiply it by the amount of paint so we get how many pints of paint are white
3/4 * 9.1 = 6.825
She used 6.825 pints of withe paint to paint her bedroom walls
1/5 of a litre is 0.2 litres
1 litre minus 0.2 litres is 0.8 litres so
0.8 divided by 5 (glasses) is 0.16 litres in each glass
Answer:
12 friends
Step-by-step explanation:
Fill in the given number and solve for x.
855 = 5x +795 . . . . . the total fee was 855
60 = 5x . . . . . . . . . . . subtract 795
12 = x . . . . . . . . . . . . . divide by 5
The number of friends you brought was 12.
