Just multiply the total length by the fraction:
14.3 * 1/10 = 1.43 miles
Answer:
x = 1, y = 60
Step-by-step explanation:
Value of new-releases (x) = $20 each
Value of classic (y) = $8 each
Total budget = $500
Equation : 20x + 8y = 500
The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.
Lets assume the librarian buys at least one new-release DVD.
x=1
20x + 8y = 500
8y + 20(1) = 500
y = 60
<em>Therefore, in a budget of $500, the librarian can purchase 60 classic movies and 1 new-release.</em>

Answer:
28 polio vaccinations and 32 measles vacinnacions.
Step-by-step explanation:
x= polio vaccinations
y= measles vaccinations
here we have an ecuation system:
x+y=60 (vaccinations)
2x+4y=184 (doses)
In order to solve it I will solve the x in the first ecuation:
x=60-y
And replace it on the other ecuation:
2(60-y)+4y=184 -----> 120-2y+4y=184------>2y=64------->y=32
Now I replace this result in x=60-y, so x=28.

Answer:
$1,665.19
Step-by-step explanation:
Interest=PRT/100 where P is the principal amount deposited by Michelle, R is the rate offered per year in terms of percentage, T is the period in years
Substituting P for $1385, T for 7 years, R for 2.89% we obtain interest as follows
Interest=$1,385*2.89*7 years/100=$280.1855
Balance after 7 years will be the sum of principal amount and interest gained
Balance=$1,385+$280.1855
=$1,665.1855
Rounding off to 2 decimal places
Balance=$1665.19
Therefore, Michelle's balance is $1,665.19
