Ben's ride is longer because 3/4 x 2 is 6/8 so 7/8 is greater than 6/8.
Hi there!
Unit rates are basically changes expressed as a quantity of one. For example, if we have something like 100 feet per second or 2 meters per hour, those are unit rates. In this case, we have a multiple-unit rate - 3 1/2 miles in 1 1/4 hours. First off, we need to simplify both fractions to an improper fraction, giving us 7/2 miles and 5/4 hours. Now, we need to divide 7/2 by 5/4.
7/2 ÷ 5/4
Find the reciprocal of 5/4:
7/2 × 4/5
Multiply:
28/10 → 2.8
Therefore, Jungkook walks 2.8 miles in one hour, or 2.8 mi/hour. Hope this helped!
Answer:
9x^3-21x^2+19x-6
Step-by-step explanation:
First you have to distribute the first equation into the second since the two are being multiplied:
(3x^2-5x+3)(3x-2)
9x^3-6x^2-15^2+10x+9x-6
(simplify)
9x^3-21x^2+19x-6
The second one orate 3rd one
There are 11 outcomes for the two events happening one after another. Since the spinner has five outcomes and the number cube has six outcomes, you add the two outcomes together and get 11.
