Answer:
He used 17/3 feet = 5 and 2/3 feet
Step-by-step explanation:
∵ He bought 9 and 1/3 feet = 28/3 feet
∵ He had 3 and 2/3 feet left = 11/3 feet
∴ He used = 28/3 - 11/3 = 17/3 feet = 5 and 2/3 feet
Answer:
100 inches
Step-by-step explanation:
A triangle has a side length of 19inches and a perimeter of 95inches. A similar triangle has a corresponding side length of 20inches. Find the perimeter of the larger triangle.
This is calculated using proportion
Side length/Perimeter
Hence:
Side length of smaller triangle = 19 inches
Perimeter of smaller triangle = 95 inchee
Side length of larger triangle = 20 inches
Perimeter of larger triangle = x
19/95 = 20/x
Cross Multiply
19x = 95 × 20
x = 95 × 20/19
x = 100 inches
The perimeter of the larger triangle = 100 inches
Answer:
x= 623/7 x =89 89 pages every night
Step-by-step explanation:
A week has 7 days
She reads 623 pages in one week(623 in 7 days)
y varies inversely with x.
Example:
If we multiply x by 2 we need to divide y by 2 too.
So,
If y = 16 and x = 1/2, find y when x = 32
Lets see, from 1/2 to 32 e need to multiply 1/2 by 64, right? So let's divide 16 by 64.
16/64 = 8/32 = 4/16 = 2/8 = 1/4
So we can say that:
If y = 16 when x = 1/2, y = 1/4 when x = 32.
m+f=38
(f-4)^2=m-4
f^2=m IF their age is 30 combined
4^2=16
16=16
Fred is 4, Mabel is 16.
