Answer:
Age of q = 42 years
Step-by-step explanation:
Ratio of the ages of three people p, q and r is 6 : 7 : 11
Sum of the ages of p and r = 102 years
Age of p =
= 36 years
Therefore, age of r = 102 - 36
= 66 years
Since, ratio of p and q = 6 : 7
Therefore,
q =
q = 42 years
Answer:
length enlarged by 10 ft
Step-by-step explanation:
Given:
Width = 11 ft
length = 22 ft
New area = 352 ft²
New length = 22 + x ft
Find:
Value of x
Computation:
(11)(22+x) = 352
242 + 11x = 352
11x = 110
x = 10
So, length enlarged by 10 ft
