47 square units is the answer on edge
Answer:Yes
Step-by-step explanation:
Given
Suppose side length of cube is a
If we dilate the cube using a scale factor of 2
Side length becomes 2a
and the surface area becomes ![=6(\text{side length})^2](https://tex.z-dn.net/?f=%3D6%28%5Ctext%7Bside%20length%7D%29%5E2)
Surface area![=6(2a)^2](https://tex.z-dn.net/?f=%3D6%282a%29%5E2)
Surface area![=4\times 6(a)^2](https://tex.z-dn.net/?f=%3D4%5Ctimes%206%28a%29%5E2)
Thus surface area multiplied by a factor of 4
Now for volume
![V=(\text{side length })^3](https://tex.z-dn.net/?f=V%3D%28%5Ctext%7Bside%20length%20%7D%29%5E3)
![V=(2a)^3](https://tex.z-dn.net/?f=V%3D%282a%29%5E3)
![V=8(a^3)](https://tex.z-dn.net/?f=V%3D8%28a%5E3%29)
Therefore volume is multiplied by a factor of 8
Therefore the above statements make sense
When you perform the indicated division, you get
![\dfrac{-3x^2+7x+1}{x-2}=-3x+1+\dfrac{3}{x-2}](https://tex.z-dn.net/?f=%5Cdfrac%7B-3x%5E2%2B7x%2B1%7D%7Bx-2%7D%3D-3x%2B1%2B%5Cdfrac%7B3%7D%7Bx-2%7D)
The "quotient" part of this result is the oblique asymptote:
y = -3x +1
Answer:
<u>C) 2parts that are one eight each.</u>
Step-by-step explanation:
The reason I chose <u>C)</u> as the correct answer is becasue I evaluated it with the steps below.
A) - 8 parts that are one fourth each.
<u>This cannot be correct because it would surpase the 2/8ths (would be over).</u>
B) - 4 parts that are one-half each.
<u>This cannot be correct because it would surpass the 2/8ths (would be over).</u>
C) - 2parts that are one eight each.
<u>This can be correct because 2 parts have 1/8th. 1/8 + 1/8 = 2/8.</u>
D) - 2parts that are one fourth each.
This cannot be correct because the denominator is not 8, it is 4 meaning it wouldn't fit into the format the question asked for (which was 2/8).
<u>This makes the correct answer C).</u>
<u></u>
I hope this helps you understand and helps you in your question.
Answer:
Step-by-step explanation:
speed = s = 3.5 miles / hour
d = 6 miles
t = ?
============
t = d / s
t = 6 / 3.5
t = 1.714 hours
t = 1 5/7 hours
You could figure this out in minutes for 5/7 but it will not make the time any clearer. You will still wind up with a fraction.
