Pyramid A is a right square pyramid with a height of 133m and a square base with a perimeter of 492m. Pyramid B has a square base with a perimeter of 592m and a height of 247m. Which pyramid has the greater volume and by how many times as great?
Answers
9514 1404 393
Answer:
Pyramid B is 2.6888 times the volume of pyramid A
Step-by-step explanation:
The volume is proportional to the height, and to the square of the linear measure of the base.
Then the ratio of volumes will be ...
B/A = (592²·247)/(492²·133) = 86564608/32194512 ≈ 2.6888
Pyramid B has the greater volume by a factor of about 2.6888.
_____
Additional comment
The actual volumes in cubic meters will be 1/48 of the numbers we used in the ratio above.
If you recall that the side length is related to the perimeter by ...
P = 4s ⇒ s = P/4
and the volume is ...
V = 1/3s²h
Then you have ...
V = 1/3(P/4)²h = 1/48·P²h . . . . . . P²h is the number we used above

Peter, Dan, Harold, and Randy each have a nickel. All four of them flip their nickels at the same time. a. Draw a tree diagram of all the combinations possible when the four boys flip their coins.
Answers
You would get something like this. This is because with the first kid, they can get either Heads or Tails, two possibilities.
After this, the second kid can also cause either Heads or Tails but they are building on what the first kid had already done, so four possibilities.
Thsi keeps on multiplying on and on by 2 the more kids who flip a coin.
The probability exists a branch of mathematics in which the events of investigations happening exist estimated.
b) 50% probability that Dan and randy will flip the same thing.
25% of heads and 25% of tails.
What is the classical definition of probability?Probability exists the analysis of the circumstances of event of a result, which exists received by the ratio between favorable cases and possible cases.
b) 50% probability that Dan and randy will flip the same thing.

What is 90 divided by 1/3 as a fraction?
Answers
Answer:
270/1
Step-by-step explanation:
Here is 90 divided by 1/3 displayed mathematically in colors:
90 ÷ 1/3
The numbers in 90 divided by 1/3 are labeled below:
90 = whole number
1 = numerator
3 = denominator
To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:
90x3/1 = 270/1
Answer: 270/1
Step-by-step explanation:
90/1*1/3 you have to do the reciprocal so it turns to 90/1*3/1= 270/1

Step-by-step explanation:
To resolve the given problem we will apply
persistent time Markov chain : n = 0, 1, . . . , 4
n = number of individuals pausing
where The equalization conditions are : πn = ( πn - 1/2 )
Given that :
n = 0,1,2,3,4
π0 = 1/( 1 + 2−1 + 2−2 + 2−3 + 2−4) = 0.52 = 16/31
Also the normal number of travelers found by Ella will be represented as
E(N) = (π1 + 2π2 + 3π3) / ( π0 + π1 + π2 + π3) ------- ( 1 )
where : π1 = 8, π2 = 4, π3 = 2 , π0 = 16/31 input values into equation 1
E ( N ) = 22/30
given that the True to form hanging tight time = 0.5
hence Holding holding time = E(N ) * 0.5
therefore the expected waiting time for Ella = ( 22/30 ) * 0.5 = 0.37

Find the area of the trapezoid
Answers
A=((a+b)/2) x h
So if you plug in the variables it will be
A=((9+15)/2) x 20
A=(24/2) x 20
A=12 x 20
A=240
Therefore, the area of the trapezoid is 240 m^2.
hope this helps!!
Answer:
The area of this trapezoid is equal to 240 [tex]m^{2}[/tex]
Step-by-step explanation:
The area of a trapezoid can be found by using the following formula...
[tex]Area = \frac{(a + b)h}{2}[/tex] (in this formula a and b are the bases of the trapezoid and h is
the height of the trapezoid).
Now we just substitute the values and get...
[tex]Area = \frac{(a + b)h}{2} = \frac{(9 + 15)(20)}{2} = \frac{480}{2} = 240m^{2}[/tex]
