Answer:

70%

Step-by-step explanation:

Find the total students who attended a school assembly:

28 + 12 = 40

If it was 25%, it would be a 90 degree angle. So we can calculate this using a proportion. 25/90 = 24/x. Cross multiply to get 25x = 2160. When you divide by 25 on both sides you get 86.4. So the angle should be 86 degrees. Hope this helps.

Number of ounces left is 1120

Step-by-step explanation:

Step 1: Find number of ounces left after each day.

Given total soup prepared each day = 15 gallons

Amount served each day = 1/4 of 15 = 15/4 gallons

Amount left after each day = 15 - 15/4 = 60 - 15/4 = 35/4 gallons

Step 2: Convert gallons into ounces. 1 gallon = 128 ounces

35/4 gallons = 35/4 × 128 = 1120 ounces

How many times larger is the volume of a cone if the radius is multiplied by 6?

yan [13]

Answer:

36 times larger.

Step-by-step explanation:

V= $\pi *r^{2}*\frac{h}{3}$ is the original volume of a cone formula.

If the radius is multiplied by 6 the new formula is:

V= $\pi *(6x)^{2} * \frac{4}{3}$

Which is simplified to:

V= $\pi *36r^2*\frac{h}{3}$

The only difference between the simplified formula and the original is the *36 so the new volume is 36 times larger when the radius is multiplied by 6.
