Sari sold 300 boxes of greeting cards in November. In december she sold 500. What was the percentage increase in her sales
grigory [225]
There was a 66 \frac{2}{3}% increase from Sari's sales from November to December. 

To find the percentage increase in her sales, we must first find the amount her sales increased. We can do that by subtracting the greeting cards sold in November from the number of greeting cards sold in December. Substituting values and simplifying, we get that she sold 200 more greeting cards in December.

To find what percent increase this is, we must find what percent 200 is of the number of greeting cards sold in November. We can do this by dividing 200 by the number of cards sold in November (300), and then multiplying by 100 (to make it a percent). Doing this, we get \frac{2}{3} * 100 which gives us our answer of 66 \frac{2}{3}%.

Jack was 13 years older than Priscilla. together their ages totaled 163 years . What were their ages?
djverab [1.8K]

Answer:

Jack is 88, Priscilla is 75.

Step-by-step explanation:

Let J represent Jack's age and let P represent Priscilla's age.

Their age totaled 163, so:

J+P=163

And we know that Jack was 13 years older than Priscilla. In other words:

J=13+P

Solve for J and P. To do so, substitute the second equation into the first:

13+P+P=163

Combine like terms:

2P+13=163

Subtract 13 from both sides:

2P=150

Divide 2 from both sides:

P=75

So, Priscilla is 75 years old right now.

Jack is 13 years older meaning that Jack is 88 years right now.

And we're done!

How do I solve this
Flauer [41]
Volume of Cylinder  V₁ =πR². H

Volume of a cone  V₂ = (1/3).πR².h

We know that H=4h (given) &  R, the radius =75 &The total Volume = V₁+V₂,
We also know that the hopper has one cylinder & 2 equal cones
Hence
πR². H + 2 [(1/3).πR².h] =343,000 ft³
π(75)².H + 2[(1/3).π(75)².h] =343,000
But H = 4h, then
π(75)².4h + 2[(1/3).π(75)².h] =343,000. Solve for h
26250.π.h = 81,466.8.h = 343,000

& h=343,000/81,466.8, ==> h=4.16 ft & H =16.6 FT
