Anew banquet hall has ordered carpeting from a factory from a factory for their new room. the carpet factory can produce 1 square yard of carpet every 10 min. how many hours would it take the factory to produce 25 1/2 square yards of carpet for the banquet hall? pl write a proportion i will give you 100 points

A proportion says:  (one fraction) is equal to (another fraction)

or  (one ratio) is equal to (another ratio).

In this question, the ratio is (the area of a piece of carpet) to (the time it takes to manufacture it.

And we know we can write the ratio as (1 square yard) / (10 minutes).

The other ratio is (25.5 square yards) / (how long THOSE take).

The carpet factory works at a  constant rate, so we know that those two ratios are equal.  So we can write:

(1 yd²) / (10 min)  =  (25.5 yd²) / (how long that piece takes) .

To solve a proportion, you "cross multiply".  That means

(left top) x (right bottom)  =  (left bottom) x (right top)

(1 yd²) x (how long the big piece takes)  =  (25.5 yd²) x (10 min)

There's an equation to solve.

Divide each side by (yd²):

(how long the big piece takes) = (25.5) x (10 min)

How long the big piece takes = 255 minutes

BUT ... the question wants to know "How many hours ..." , so you have to convert the 255 minutes into hours.  You should be able to do that, because you certainly know that 60 minutes = 1 hour.

Big piece = (255 minutes) x (1 hour / 60 minutes)

Big piece = (255/60) hours

Big piece = 4.25 hours  (that's 4 hours 15 minutes)

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

i can you with this sweetie!
