The value of 1 penny, 1 nickel, and 1 dime is $0.16. The total value of the coins is 8 times that, so the bank contains 8 of each coin.
Answer:
x = 1.91 ft
Step-by-step explanation:
We use cosine because we are dealing with Adj and Hyp
cos 80 = x/11
x = 11 cos 80
x = 1.91 ft
$18.11 because 20.75/x=100/15
<span>(120.75/x)*x=(100/15)*x - </span>we multiply both sides of the equation by x
<span>120.75=6.6666666666667*x - </span>we divide both sides of the equation by (6.6666666666667) to get x
<span>120.75/6.6666666666667=x </span>
<span>18.1125=x </span>
<span>x=18.1125</span>
Answer:
14/3
Step-by-step explanation:
2 1/3=7/3
2*7/3=14/3
When we multiply a whole number with a fraction, we can think of the whole numbers as "over one"...
5 3 5 15
3 * --- = --- * ---- = ----
6 1 6 6
We can further simplify the fraction, by dividing numerator and denominator by 3...
15 15 / 3 5
--- = ------- = ----
6 6 / 3 2
Since this is an improper fraction, we need to turn it into a mixed number...
5 2 + 2 + 1 2 2 1 1 1
---- = -------------- = --- + ---- + --- = 1 + 1 + ---- = 2 --- or 2.5
2 2 2 2 2 2 2
