Your still will be 22 years old when your brother is 29.
I hope that helped! c:
<u>Finding the proportionality constant</u> :
- y = k/x
- 16 = k/(1/2)
- <u>k = 8</u>
<u>Finding y when x = 17</u> :
The value of y is <u>8/17</u> when x = 17.
Answer:
20m
Step-by-step explanation:
Given the formula that modelled the height given as;
h=30+40t-5t^2
At t = 4s
h=30+40(4)-5(4)^2
h = 30+160-80
h = 160-60
h = 110m
At t = 2s
h=30+40(2)-5(2)^2
h=30+80-20
h = 110-20
h= 90m
Difference in height = 110-90 = 20m
Hence the height is 20m higher above the ground at 4s than at 2s
36
6×6
3×3×3×3
that is your answer
3/4=x/60 so you divide 60 by 4 and get 15x3=45/60
