Answer:
300 miles/hour
Step-by-step explanation:
The average speed = 1500 / 5
Answer:
The smallest power of 10 that will exceed
is
.
Step-by-step explanation:
We can use the following approach to determine the smallest power of 10 that will exceed M. We can transform that number into scientific notation, which is of the form:
, 
Where:
- Integer part, formed by a digit, which is of the highest order.
- Decimal part, formed by a digit onwards.
- Power grade.
The smallest power of 10 that will exceed M is 
If
, then, the power grade is number of spaces that dot must be moved leftwards. In this case, dot must be moved 5 spaces on the left. The integer part is 1 and the decimal part is 1852665902. Then, the value of
in scientific notation is:

Then, the smallest power of 10 that will exceed
is
.

Answer:
A, B, C, E, D
F, G, H, I, J
Step-by-step explanation:
You can go at this a couple of ways.
Consider the squares of number 1 through 9.

Then when the number under the radical is close to n², the root on the number line will be close to n.
The other way you can do this is to find the square root using your calculator.
- √10 ≈ 3.2 ⇒ A
- √35 ≈ 5.9 ⇒ B
- √48 ≈ 6.9 ⇒ C
- √71 ≈ 8.4 ⇒ E
- √54 ≈ 7.3 ⇒ D
- √19 ≈ 4.4 ⇒ F
- √89 ≈ 9.4 ⇒ G
- √6 ≈ 2.4 ⇒ H
- -√20 ≈ -4.5 ⇒ I
- -√2 ≈ -1.4 ⇒ J
