Answer:
53.5
Step-by-step explanation:
c = the height of the first 3 boys.
c = 54 + 48.5 + 46
c = 148.5
Now you add a fourth boy. His height is h.
A(h)= (c + h)/d
d = the total number of boys which is 4.
The new average is 50.5
A = (c + h)/d
50.5 = (148.5 + h) / 4 Multiply both sides by 4
202 = 148.5 + h Now subtract 148.5 from both sides
202 - 148.5 = h
h = 53.5
The correct answer is C. $2
Answer:
A
Step-by-step explanation:
We need to find out which 2 numbers round to the nearest tenth is 53.6.
A. 53.542 The hundredths is 4 so the tenths does not round up. Rounded is 53. 5, which is not the answer
B. 52.591 The hundredths is 9 so the tenths round up. Rounded is 52.6, which is also not the answer
C. 53.615 The hundredths is 1 so the tenths does not round up. Rounded is 53.6, which is one of the answers
D. 53.545 The hundredths is 4 so the tenths does not round up. Rounded is 53.5, which is not the answer
E. 53.551 The hundredths is 5 so the tenths does round up. Rounded is 53.6, which is one of the answers
The two answers are C. 53.615 and E. 53.551 because both rounds to 53.6.
