Step-by-step explanation:
let father's age be f yr old and son age be s yr old
f = 5s -(1)
f + s = 60 -(2)
sub (1) into (2):
5s + s = 60
6s = 60
s = 10
f = 60 - 10 = 50
in 5 yr time, father age = 50 + 5 = 55
son age = 10 + 5 = 15

Answer:
Step-by-step explanation:
Part A
Area of a rectangle = length x width
Garden area = 7 3/4 x 2 2/3
= 31/4 x 8/3
= 62/3
= 20 2/3 square feet
Part B
5/8 of the area = 62/3 * 5/8
= 31*5 / 3*12
= 155 / 36
= 4 11/36
The question asks to do so without calculation - the only way is that because the length is approximately 8 feet, section off 5 feet along the length will give an area approximately 5/8 of the total area.
Answer:
Cross section
Step-by-step explanation:
When we slice a three-dimensional object, we expose new faces that are two dimensional. The two-dimensional face is called <u>cross section</u> .
