Answer:
25.50
Step-by-step explanation:
-5 notebooks $2 each
-4 pencils $1.50 each
-2 packs of markers $3.75 each
5(2)+4(1.50)+2(3.75)
$23.5
23.5 times 8.5/100
1.9975
plus 23.5
25.4975
rounded to 25.50
4:2 and 2:1 are equivalent ratios to 8:4
Let the ratio between 2 of them be a/b. The volume of the larger one is x (ft^3)
<span>(a/b)^2 = 20/45 = 4/9 ---> a/b = 2/3 </span>
<span>(a/b)^3 = 8/x </span>
<span>8/x = (2/3)^3 = 8/27 ---> x = 27 (ft^3) </span>
