Answer:

22(c)

Step-by-step explanation:

Our current proportion is

15 miles

-------------

1 hour

We need feet per second.

Lets convert!

15 miles= 79200 feet(used googl to find this)

1 hour=3600 seconds(also used googl to find this)

( i know its not spelled that way brainly wont let me write the whole word out)

Now, our proportion is:

79200 feet

-----------------

3600 seconds

HOWEVER, this can be simplified!!!!

79200/3600=22

Final answer: 22, or C.

Which of the following shows the correct value of 50
Orlov [11]

Answer:

None of the options is correct

Step-by-step explanation:

It is important to know that he expression a < x < b means that x is greater than a and less than b. So, for finding the correct value let's analyse each option.

A. 4 < 50 < 5

50 is greater than 4 but it is not less than 5, so, option A is incorrect.

B. 7 < 50 < 8

50 is greater than 7 but it is not less than 8, so, option B is incorrect.

C. 8 < 50 < 9

50 is greater than 8 but it is not less than 9, so, option C is incorrect.

D. 10 < 50 < 11

50 is greater than 10 but it is not less than 11, so, option D is incorrect.

Thus, none of the options is correct.

Which is equal to 7(3.5x10^4)written in scientific nation
k0ka [10]
The answer is 2.45 x 10^5. 

7 x 3.5 = 24.5

Move the decimal place over to the left until you have a number between 1 and 9 before the decimal point.

Add the number of times you moved the decimal point to the exponent (The 4 in the original equation).

2.45 x 10^5.

I hope this helps!
