Aferris wheel can accumulate 75 people in 30 minutes how many people could ride the ferris wheel in 4 hours what was that rate per hour

600 people

Step-by-step explanation:

We can use ratios to solve this problem.

Change the 30 minutes in to hours

30 minutes = .5 hours

75 people               x people

=

.5 hours                    4 hours

Using cross products

75*4 = .5 *x

300 = .5x

Divide each side by .5

300/.5 = .5x/.5

600 =x

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

you just switch the numbers basically so it would be 3/17
