Answer:
C.
is 5 times larger than ![4\times 10^6](https://tex.z-dn.net/?f=4%5Ctimes%2010%5E6)
Step-by-step explanation:
We want to compare
and
.
In order to determine how many times
is larger than
,
we need to divide
by
to obtain;
![\frac{2\times 10^7}{4\times 10^6} =\frac{10}{2} =5](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Ctimes%2010%5E7%7D%7B4%5Ctimes%2010%5E6%7D%20%3D%5Cfrac%7B10%7D%7B2%7D%20%3D5)
Therefore we can see that;
is 5 times larger than ![4\times 10^6](https://tex.z-dn.net/?f=4%5Ctimes%2010%5E6)
The correct answer is C.
10^2 = 100
So 2 * 100 = 200

Answer: 75 minutes per hour.
Step-by-step explanation:
From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.
The rate per hour will then be:
= 15 ÷ 1/5
= 15 × 5
= 75 minutes
The rate per hour will then be 75 minutes per hour.
Answer:
17/20
Step-by-step explanation:
3/4 + 4/5 - 7/10
1. Find the LCD (Least Common Denominator). The LCD is 20.
2. 20/4=5. 5*3=15. So, 3/4 becomes 15/20.
3. 20/5=4. 4*4=16. So, 4/5 becomes 16/20.
4. 20/10=2. 2*7=14. So, 7/10 becomes 14/20.
5. Your new equation is 15/20 + 16/20 - 14/20.
6. Solve from left to right.
7. 15/20 + 16/20= 31/20.
8. 31/20 - 14/20= 17/20.
