<span>There are 60 seconds in a minute.
To find out how many copies in a second, divide 36 by 60.
That is 0.6
Then you would calculate to see how much in 15 seconds,
0.6 times 15
9 copies in 15 seconds
then multiply 36 * 4 to see how many in minutes
144 copies in 4 minutes
153 copies in 4 minutes and 15 seconds.
Hope this helps :)

Answer:
$1440
Step-by-step explanation:
First find the the area with feet.
18*16=288
Now convert into sq. yards
288/3=96
Finally, multiply 96 by 15
96*15=1440
$1440
Okay so first of all you have to divide the -6 that’s in the parenthesis because it’s by itself. Then when you divide it you should have k by itself and your final answer would be 2.
Hope that helps!
Answer:
-2x+4r = 4 i think
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the speed of the current be c
<u>Time upstream is</u>
<u>Time downstream is</u>
<u>Total time is 8 hours</u>
- 55/(16 + c) + 55/(16 - c) = 8
- 55(16 -c + 16 + c)/(16 + c)(16 - c) = 8
- 55*32= 8*(16² - c²)
- 220 = 256 - c²
- c² = 36
- c = 6 mph
