We know that
• It takes 8 hours to travel a certain distance at 36 miles per hour.
,
• At 60 miles per hour, how long would it take?
We solve this problem using the rule of three, or proportions. The image below shows the given relations.
We form the proportion. We have to write down 60 as numerator because it has an inverse relationship, that is, the more speed the least time needed.
<h2>Therefore, it would take 4.8 hours to travel the same distance at 60 miles per hour.</h2>
Answer: 5/8 < 3/8
=======================================================
Reason:
The denominators are both 8, so we can compare the numerators.
The statement 5 < 3 is false, so 5/8 < 3/8 is also false.
------------
Or you could use your calculator to see that:
Since 0.625 < 0.375 is false, this makes 5/8 < 3/8 to be false
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
Emily's number was 28
Answer:
-16/45
Step-by-step explanation:
(-8 x 2) / (9 x 5)
-16/45
8.71 xx10^(12)
The exponent is a positive number. This means the decimal point moves to the right by the number of the exponent.
There are two digits to the right of the decimal point, so to move the decimal 12 places, you would need to add 10 zeros.
8.71 x 10^12 becomes 8,710,000,000,000.
