A museum has 450 visitors each day. If they are open 5 hours, how many people do they see per hour?

lions [1.4K]

Answer: 90 visitors per hour

Explanation: "Per hour" means in 1 hour, so we can rewrite the given statement using fractions as 450 visitors/5 hours = __visitors/1 hour.

To find out what goes in the bank, notice that we

have a 1 in the denominator of our second fraction.

So we want to find a fraction that is equivalent

to 450/5 that has a 1 in the denominator.

If we divide the numerator and denominator of 450/5 by 5,

we get the equivalent fraction 90/1 or 90 visitors/1 hour.

So now we have 90 visitors/1 hour = __visitors/1 hour.

So a 90 must go in the blank.

This means that the museum sees 90 visitors per hour.

Answer:

Step-by-step explanation:

Given, 

Dimensions of the rectangular prism = 9ft, 12ft and 4ft

Therefore, 

Surface area of the rectangular prism

= 2( lb + bh + lh)

$= 2(12 \times 9 + 9 \times 4 + 12 \times 4) {ft}^{2}$

$= 2(108 + 36 + 48) {ft}^{2}$

$= 2 \times 192 {ft}^{2}$

$= 384 {ft}^{2}$

Hence,

Surface area of rectangular prism is 384 sq. ft (Ans)
