Answer:
belive in yourself and try best
Let Karen, Michelle and their brother be represented by constants k, m and b respectively.
According to your question,
k = 6 + m
b = m + 2
k + b + m = 62.
Substituting for k and b in equation 3,
(6 + m) + (m + 2) + m = 62
= 3m + 8 = 62
3m = 54
m = 18.
Thus, k = 6 + m = 24
b= m + 2 = 20.
Thus, Karen's age is 24, Michelle's age is 18 and their brother's age is 20
Answer: 2,849.6 mm^3
Step-by-step explanation:
Volume of a cone : 3.14 • r^2 • h/3
h being height and r being radius
now substitute
3.14 • 5.5^2 • 90/3
now solve
3.14 • 30.25 • 30
2849.55
round to tenths
2849.6
