Step-by-step explanation:
The volume of a right square pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
The volume of the larger pyramid will be ...
V' = 1/3(5B)h
So, the ratio of volumes is ...
V'/V = (1/3(5B)h)/(1/3Bh)
V'/V = 5
The ratio of volumes is 5.

Answer:
To find the amount that it accelerated, you need to find the change in the mph. First you would subtract 70 and 10 to find that number. That tells you the total amount of change. Then to figure out how much it would be per second you divided that number by the total number of seconds (12).
Step-by-step explanation:
The net below has dimensions l = 14 feet, w = 7 feet, and h = 13 feet. How will the surface area of the figure change if the width decreases by 2 feet?
Step-by-step explanation:
So, we know that the width in this image has a length of 7 feet. decreasing it by two will give us 5 feet. Now, we can solve the surface area.
Lateral faces: 7 x 14 x 4 = 392
Bases: 14 x 13 x 2 = 364
Add them all up, and we get 756 ft²

If u={a,b,c,d}and p={b,d,e}find p(bar at the top)
Answer:
{a , c}
Step-by-step explanation:
first find u intersection p
n(U n P ) = {a , b , c , d} n {b , d , e}
={d , b}
intersection means element or values which lies in both the sets
now to find p complement
note : p( bar at the top ) is read as p complement
p complement = n(U) - n(U n P)
={a , b , c , d} - {d , b}
={a , c}
n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)
Answer:
a,c

Taivon is training for a running and biking race. The biking part of the race is longer than the running part, so while Taivon trains, he wants to bike more than he runs. He decides that for every 4 miles he runs, he wants to bike 16 miles. How far should Taivon bike if he runs 11 miles?
Answer:
44 miles
Step-by-step explanation:
He bikes 4 miles for every mile he runs so 11 times 4 = 44.

How much money is there?
Pls helppppppppppp meeee
=======================================================
Explanation:
There is a dime and 2 quarters in the bottom row.
So we have 10+25+25 = 60 cents in the bottom row.
Then in the top row, there's a penny and a nickel. So that's an extra 1+5 = 6 cents.
Overall, the total value is 60+6 = 66 cents
Note: 66 cents converts to $0.66 or you can say 0.66 dollars.

help pleaseeee. this is due in an 10 minutes
Answer:
(you'll have to read the explanation)
Step-by-step explanation:
There are 8 lines from 1 to 2, so plotting 1 1/2 (or 1.5) is right in between. I'm not sure how to add the picture back into the explanation, but I will try my best to explain. You want to plot your point for 1 1/2 4 lines after the 1. For the 2 1/4, you want to plot your point on the second line from the 2. Let me know if it doesn't make sense!
Answer: See the attached image below
1 1/2 is located at the exact midpoint between 1 and 2.
2 1/4 is located 2 tickmarks to the right of 2.
===================================================
Explanation:
Think of 1/2 as 4/8
The number 1 1/2 is the same as 1 4/8
So we start at 1 and move 4 tickmarks to the right to get at the exact midpoint (note there are 8 tickmarked spaces between any two whole numbers).
This places us exactly at the midpoint between 1 and 2.
-----------------
To plot 2 1/4, we will effectively plot 2 2/8 since 1/4 = 2/8
We start at 2 and then move 2 tickmarks to the right to arrive at 2 2/8

A) 15/25 = 10/p
Answer:
p = 50/3
Step-by-step explanation:
15/25 = 10/p
Using cross products
15*p = 25*10
15p = 250
Divide by 15
15p/15 = 250/15
p = 50/3
Answer:
[tex]\displaystyle p = \frac{50}{3}[/tex]
