It is 120 because you have to divide 210 by 7 which is 30 then multiply by 4 so 30 x 4 = 120.

Convert 2000 ft./min. to miles per hour round to the nearest 10th
Serggg [28]

Answer:

The conversion of 2000 ft per min into miles per hour is 2.268 miles per hour .

Step-by-step explanation:

Given as :

The speed = s = 2000 ft per min

Now, ∵ 5280 feet = 1 miles

so, 1 feet = \dfrac{1}{5280} miles

∴ 2000 feet =  \dfrac{1}{5280} × 2000 miles

i.e 2000 feet = 0.378 miles

<u>Again</u>

∵ 1 minute = \dfrac{1}{60} hour

So, The speed in miles per hour

s = \dfrac{distance}{time}

∴ s = \frac{0.378}{\frac{1}{60}}

i.e s = 2.268 miles per hour

Hence, The conversion of 2000 ft per min into miles per hour is 2.268 miles per hour . answer

Which of the following numbers is not a perfect square?<br><br> 24<br> 25<br> 64<br> 100
stich3 [128]
Hi! 

A perfect square is the product of when a whole number is multiplied by itself

Ex:

6 × 6 = 36, 36 is the perfect square. 

The number that is being multiplied is the square root. 

So to find the correct answer for this question, let's use the process of elimination. 

100 = 10 × 10 so we can cross out 100

64 = 8 × 8 so we can cross out 64

25 = 5 × 5 so we can cross out 25

Now all we have left is 24, which is not a perfect square. 

Answer: A. 24

Hope this helps :)
