Answer:

C

Step-by-step explanation:

When you add all rentals together you should get 125, after this you see what the problem is asking, in our case, the probability of not renting a drama, as said, our total is 125. When we look at how many dramas have been rented you get 25, simply, you divide 125 by 25, therefore you should get 5, so now, we know that there is a 1/5 possibility for getting it but because its not 5/5.

Thus, there should be 4/5 which is the probability of it not getting chosen.

Luda [366]

Answer:

Surface area of the refrigerator is 864 in².

Step-by-step explanation:

If side length 's' = 12 inches

By substituting this value in the formula,

Surface area = 6(12)²

                     = 864 inch²

Therefore, surface area of the refrigerator is 864 in².

if you share the costs of a meal on the ratio of 2:3 and one person pays £52.20 how much was the whole meal?
Tju [1.3M]
<em>The ratio of shared costs of mean=2:3.
One person paid the cost </em>
£<em>52.20, so let the other person paid the cost be X.
</em>
<em>(2/3)=(52.20/X)
</em><em>X=(52.20</em>×3)/2
X=26.10×3
X=78.30
So the gross cost paid by both the person = £(78.30+52.20)
⇒£130.60
