.53= 53/100
53/100 cannot be simplified so the answer is 53/100
C. 19.42% because you subtract 389.85 from 314.15 which equals 75.7. So then set it up like an algebraic equation. 389.85x=75.7 divide 75.7 by 389.85 to find the decimal. Then you have to move the decimal to the right two places, since it is a percentage. And then round your answer, so c. 19.42% is your answer. Hope this helped! :)
16 x 6 = 96
96 - 7 = 89
or

Answer : 89 slices
Answer:
Step-by-step explanation:
<u>The filling speed is 30 hours or:</u>
<u>The draining speed is 34 hours or: </u>
<u>If both lines are open simultaneously, the filling speed is:</u>
- 1/30 - 1/34 =
- 17/510 - 15/ 510 =
- 2/510 =
- 1/255 in an hour
<u>If the tank is 1/5 full, then we need to fill the 4/5 of level and it will take:</u>
- 4/5 : 1/255 =
- 4/5 *255 =
- 204 hours
Total surface aera
1 big recangle and 2 triangles
rectangle has base of 3+4+5= 12
12*7=84
the 2 triangles
has base is 4
height of 3
2 of them
2*1/2*3*4=12
add total
84+12=96 in^2
