(ANSWER FOR FREE BRAINPOINTS!) (FIRST TO ANSWER GETS BAINLIEST) The local park has a rectangular swimming pool that measures 40

iren [92.7K]

Answer:

9 yards

Step-by-step explanation:

Since both pools are similar, therefore the ratio of their length and width would be equal. That is:

Length of the current swimming pool : length of the new swimming pool = width of the current swimming pool : width of the new swimming pool

Thus, we can set up a proportion as shown below:

Let the width of the new swimming pool be x.

40 : 24 = 15 : x

$\frac{40}{24} = \frac{15}{x}$

Cross multiply

$40*x = 15*24$

$40x = 360$

Divide both sides by 40

$x = \frac{360}{40}$

$x = 9$

The width of the new swimming that is smaller would be 9 yards.

46. Merchandising If 12 items are in a dozen, 12 dozen are in a gross, and 12 gross are in a great-gross, how many items are in

Andrews [41]

Answer: 1728

Step-by-step explanation: You multiply 12 times 12 because we have to find how many items are in a 12 dozen first which is 144 because there are 12 items in one dozen. We already know that there are 144 items in 12 dozens and there are 12 dozens in a gross, which is 144 items in total. Now we have to multiply 144 times 12 to find how many items are in a great gross. 144 times 12 is 1728.
