Answer:

21. Vol. = L ^ 3

or, 27000 = L ^ 3

or, cube root undefr 27000 = L

Therefore, Edge length = 30 cm

22.

a. v = l ^ 3

or, 64000 = l ^ 3

or, cube root under 64000 = L

or, l = 40 cm

Also,

surface area = 6 a ^ 2

= 6 * 40 ^ 2

= 6 * 1600

= 9600 cm ^ 2 #

Clark has a box of nickels and dimes that totals $1.90. there are a total of 27 coins. how many nickels and dimes does he have?
Andrej [43]
$0.05(n) + $0.10(d) = $1.90
n + d = 27
n + d - d =27 - d
n = 27 - d

$0.05(27-d) + $0.10(d) = $1.90
1.35 - 0.05d + 0.10d = $1.90
1.35 +0.05d = $1.90
1.35 - 1.35 +0.05d = $1.90 -1.35
0.05d = 0.55
0.05d/0.05 = 0.55/0.05
d = 11

n = 27 - 11
n = 16

$0.05(16) + $0.10(11) = $1.90
$0.80 + $1.10 = $1.90
$1.90 = $1.90
