Your uncle has 36 coins in nickels and quarters. The value of his nickels is 1/15 of the value of his quarters. Find the number
Ostrovityanka [42]

Answer:i

Step-by-step explanation:

Total coin = 36

Let the no. Of quarter = x

No. Of nickel = 1/15 × x = x/15

So, x + x/15 = 36

Multiply each terms by 15

15x + x = 540

16x = 540

x = 540/16

x = 33.75

Nickel is x/15 = 33.75/15 = 2.25

Katherine wants to construct a small box with a volume of 20 cubic inches with the following specifications. The length of a box
kondor19780726 [428]
In this question, you have to form the equation given the formula of the volume : L x W x D
L = W+5
W = W
D = W-1

(W+5)(W)(W-1) = 20
(W^2+5W)(W-1) = 20
W^3+4W^2-5W-20 = 0

Get the roots by factoring it out.
<span>(w +4) *(w +2.236) *(w -2.236)
</span>
So the roots are: -4, -2.236, 2.236.
Since we're talking about dimensions, let's use the positive root..

L = 7.24
W = 2.24
D = 1.24
