Given:
Consider the complete question is "A speed walker covered
mi in
hour. How far will he walk in 3/4 hours if he walks twice as fast?"
A speed walker covered
mi in
hour.
To find:
Distance covered by him if in 3/4 hour if he walks twice as fast.
Solution:
We have,

It means a speed walker covered
mi in
hour.
If the speed is twice then he can cover double distance is same time.
Distance covered by him if in 3/4 hour if he walks twice as fast is

Therefore, distance covered by him is 9 mi.
Step-by-step explanation:
I think you mean that 10 cm³ of air are escaping every second.
and we start with a volume of 500 cm³.
V = 500 - 10t 0 <= t <= 50
because negative t (seconds) don't make any sense, and neither does a negative volume (for t > 50).
Answer:
the answer is 1/9
Step-by-step explanation:
-3^0 divided by -3^2= 0.111111111
0.111111111 converted it equals 1/9
38 % of amount is spent on broadcast TV advertising
<em><u>Solution:</u></em>
Given that,
Amount spend on broadcast TV ad = $ 22, 000
Amount spend on cable TV ad = $ 30, 000
Amount spend on radio ad = $ 6000
To find: percentage of broadcast TV advertising
Total amount = $ 22, 000 + $ 30, 000 + $ 6000
Total amount = $ 58000
percentage of broadcast TV advertising = 

Thus 38 % of amount is spent on broadcast TV advertising
