Using the relation between velocity, distance and time, it is found that:
- The rate of the plane in still air is of 140 mph.
- The rate of the wind is of 40 mph.
<h3>What is the
relation between velocity, distance and time?</h3>
Velocity is <u>distance divided by time</u>, that is:
A plane traveling with the wind travels 900 miles in 5 hours, hence:
The return trip is against the wind and takes 9 hours, hence:
From the first equation, we have that:
![v_w = 180 - v_a{/tex]Replacing on the second:[tex]v_a - v_w = 100](https://tex.z-dn.net/?f=v_w%20%3D%20180%20-%20v_a%7B%2Ftex%5D%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%3Cstrong%3EReplacing%20%3C%2Fstrong%3Eon%20the%20second%3A%3C%2Fp%3E%3Cp%3E%5Btex%5Dv_a%20-%20v_w%20%3D%20100)
[tex]v_w = 180 - 140 = 40{/tex]
Hence:
- The rate of the plane in still air is of 140 mph.
- The rate of the wind is of 40 mph.

Answer:
438.501cm^3
Step-by-step explanation:
Given data
Height of can= 12cm
Radius= 3.5cm
The capacity of the can is expressed as
V= πr^2h
V= 3.14*3.5^2* 12
V= 3.14*12.25*12
V= 461.58cm^3
Hence the capacity is 461.58cm^3
We are also given that the juice amount to 95% of the capacity of the can
95/100*461.58= x
0.95*461.58=x
x=438.501cm^3
This means that the volume of the juice is 438.501cm^3
24+16=40
100/40=2.5
2.5 x 16 = 40
40% of the flowers are yellow

Answer:
A
Step-by-step explanation:
i = items sold
p = profit
Based on the table, the profit is twice the number of items sold. Therefore the answer is A. Correct me if I'm wrong. I hope it helps.
