Answer: 19 minutes
Step-by-step explanation:
Here is the complete question:
takes Andrew 720 seconds to take a shower. He spends an additional 420 seconds eating breakfast.
How many minutes does it take Andrew to take a shower and eat breakfast?
From the question, we are told that Andrew spends 720 seconds to take a shower and also spends an additional 420 seconds eating breakfast. The total time spent by Andrew will be:
= 720 seconds + 420 seconds
= 1140 seconds
We will then convert 1140 seconds to minutes. We should note that 60 seconds = 1 minute. Therefore,
1140 seconds = 1140/60
= 19 minutes
Andrew uses 19 minutes to take a shower and eat breakfast.
Answer:
Jordan needs
of carpet to cover the surface area of the post
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The surface area of a prism is equal to

where
B is the area of the base of the prism
P is the perimeter of the base of the prism
h is the height of the prism
<em>Find the area of the base B</em>

<em>Find the perimeter of the base P</em>

we have the height h

substitute the values


Given:
L = W - 4
P = 2L + 2W
We can substitute 2L for 2(W - 4) = 2W - 8
So:
2W - 8 + 2W = P
P = 4W - 8
Answer is 4. 4W-8
