The cup was filled at a constant rate. It started empty. After 2 seconds, it held 70 cm^3 of water.

nydimaria [60]

Answer:

About 90%

Step-by-step explanation:

If the cup was filled at a constant rate, then the cup fills at 70/2=35 cubic centimeters per second. The formula for the volume of a cone is $\frac{1}{3} \pi r^2 h$ , or in this case $\frac{112}{3}\pi$ cubic centimeters. After 3 seconds, the cup would have 35*3=105 cubic centimeters of water inside of it, or about 89.52% which rounds to 90%. Hope this helps!

What is -11 + 3(b + 5) = 7

IRISSAK [1]

Answer:

b=1

Step-by-step explanation:

$\sf -11 + 3(b + 5) = 7$

<u>First, let's regroup, terms,</u>

$\sf 3(b+5)-11=7$

<u>Add 11 to both sides,</u>

$\sf 3(b+5)=7+11$

<u>Simplify, 7+11 = 18,</u>

$\sf 3(b+5)=18$

<u>Now, divide both sides by 3,</u>

$\sf b+5=\frac{18}{3}$

<u>Simplify, 18/3 = 6,</u>

$\sf b+5=6$

Subtract 5 from both sides,

$\sf b=6-5$

$\sf b=1$

Hope it helps! :)
