Question:
Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?
Choose 1 answer:
C. None of the above
Answer:
Step-by-step explanation:
Given
Numbers: 1.7 and -1/2
Required
Determine the distance
To calculate the distance, we start by calculating the difference between the given numbers;
Then, we calculate the distance;
<em>In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;</em>
Hence,
Substitute 
for Difference;
<em>Hence, the correct option is B</em>
Answer:
2:30 pm
Step-by-step explanation:
In two hours (from 10am), she is 45 * 2 = 90 miles from vacation cabin.
From then on her average is still 45 mph and her husband's is 65 mph. So, husband catches her 20 miles (65-45=20) in every hour.
<em>The husband has to catch up 90 miles. How long would it take if he is catching up at 20 miles an hour?</em>
<em>90/20 = 4.5 hours</em>
<em />
<em>So husband starts at 10am and 4.5 hours form that time is 2.30pm</em>
Answer: d is correct
Step-by-step explanation:
Mathematical Answer: 2cups*3/4 = 1 and 1/2 cups or 1.5 cups.
How to do it while cooking:
- Get out a container large enough to hold at least 4 cups sauce
- Get out a "1 cup" and "1/2 cup" measuring cup.
- Measure out 1 cup of sauce with the "1 cup" measuring cup.
- Measure out 1/2 of a cup of sauce with the '1/2 cup' measuring cup.
- pour both cups into the larger container.
And there you go you have 3/4 of 2 cups of sauce.

3.2 * 10^-4 = 0.00032
So the number is less than 1.
The effect the negative exponent has is.....well...here's an example
if the exponent was a positive it would be 3.2 *10^4 = 32,000
If it was positive you would move the decimal point to the right (for this equation) 4 times... if it was negative you would move it the other way.
