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:
Step-by-step explanation:
The correct domain consists of only five integers: {0, 1, 2, 3, 4} It's possible that the customer buys NO melons; that's why we have that 0 in the domain. No customer may buy more than 4 melons; that's why the domain does not include numbers greater than 4. Only whole melons are sold, which is why the domain contains no fractions, no mixed numbers.
Answer:
7
Step-by-step explanation:
1/2(x)=7/2
divide both sides by 1/2
x=
÷
x=·
x=14/2=7
His co-payment for his physician visits would be:
10 x 18 = $180.
His co-payment for his physical therapy would be:
10 x 20% x 150= $300.
You then have to add both co-payments which give you $480.
<span> a=2.5b-11, c=1.5b+1, and a=c so
2.5b-11=1.5b+1
b=12 so a=19 and c=19
so a+b+c=50 </span>
