Total age of pupils
= 12.7 x 10
= 127 years
127 - 11 - 10 - 12 - 11 - 14 - 13 - 14 - 16 = 26 ( total age of the other 2 pupils added together )
however, since the ninth pupil is two years younger,
26-2=24
24/2=12 ( age of ninth pupil )
12+2=14 ( age of tenth pupil )
thus, (a) 12 years old,
(b) 14 years old.
Answer:
80 minutes
Step-by-step explanation:
We can solve this problem using rule of three:
The ratio of number of minutes and number of miles is 24 to 3, that is, for each 24 minutes running, she runs 3 miles.
So, if to run 3 miles she needs 24 minutes, to run 10 miles, how much time she will need:
3 miles -> 24 minutes
10 miles -> X minutes
3/10 = 24/X
X = 10 * 24 / 3 = 80 minutes.
She will take 80 minutes to run 10 miles.
11/131 is 0.084, 8.4% or 8%.
Answer:
The area of a rectangle with a width of 5 inches, and a height of 2.5 inches, would have an area 12.5 inches!
Step-by-step explanation:
To find the area of a rectangle, simply multiply the width (W) by the length (L) to find the area (A) of the rectangle.
A = W x L
A = 5 inches x 2.5 inches
A = 12.5 inches

The nearest hole number would be 4 , if it is .5 and above then it gets rounded up to the next number and if it is .4 or less that you round it to the whole number
