Answer: Martha spend $537.25 in june to have the same average as in the first quarter.
Step-by-step explanation:
Given that,
Average monthly expenditure for the first quarter= $396.25
Expenditure in April= $401.50
Expenditure in May= $250.00
Suppose, expenditure in June= x
To have the same average as in the first quarter, we have to take the average of the second quarter equals to the average of first quarter.
So,
Average monthly expenditure for the second quarter= $396.25
Using the formula of average for monthly expenditure for second qaurter as follow:
Average monthly expenditure for months April, May, and June= Sum of expenditure of April, May, and June divided by 3.
So,
396.25= (401.50 + 250.00 + x)/3
1188.75= 651.5 + x
x= 537.25
Answer:
372 inches
Step-by-step explanation:
(1 yd = 36 in., and 1 ft = 12 in.)
1 yard stick = 24 in
This means , height of 36 inches casts a shadow of 24 Inches
At the same time a telephone pole casts a shadow of 20 ft 8 in
1 ft = 12 in
Hence,
Convey 20ft to inches
1 ft = 12 in
20 ft = 20 × 12 inches
= 240 inches
Total shadow of the telephone pole = 240in + 8 in = 248 = 248 inches
Hence,
Height/Length of shadow = Height/Length of shadow
36/24= x /248
Cross Multiply
24 × x = 36× 248
x = 36 × 248/24
x = 372 inches
The height of the telephone pole, to the nearest inch is 372 inches
