Answer:

<h2>The second pyramid, placed in the middle, has a volume of 15 square units.</h2>

Step-by-step explanation:

Givens

  • The area of the bases is 15 square units.
  • All of them have the same base.

The volum of a pyramid is defined as

V=\frac{1}{3}Bh

WhereB is the are of the base and h is the height.

So, all of them have B=15u^{2}

The first pyramid has a height of 4, replacing this in the formula we have

V=\frac{1}{3}15(4)=5(4)=20u^{3}

The second pyramid has a height of 3

V=\frac{1}{3}15(3)=5(3)=15u^{3}

The third pyramid has a height of 12

V=\frac{1}{3}15(12)=5(12)=60u^{3}

Therefore, the second pyramid, placed in the middle, has a volume of 15 square units.

The odds in favor of jim beating a friend at golf are 1:8. find the probability that jim will win.
agasfer [191]

The probability that jim will win = P(A) = 1/9

<h3>What is  probability?</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

<h3>According to the given information :</h3>

The odds in favor of jim beating a friend at golf are =  1:8

Let A be the event that Jim beating a friend golf.

So,

according to ratio, it becomes

P(A)/P(A') = 1/8

P(A) = 1x

P(A')  = 8x

we know that :

P(A) + P(A') = 1

x + 8x = 1

9x = 1

x = 1/9

so that

P(A) = 1/9

P(A')  = 8/9

the probability that jim will win = P(A) = 1/9

Jill drives 75 1/3 miles every hour how many miles can Jill Drive in 8 and 3/4 hours
11Alexandr11 [23.1K]
First, multiply 75 by 8 to get 600. 
Then multiply 1/3 by 8 to get 8/3 or 2 2/3. 
Add those together to get 602 2/3. 

Next multiply 1/3 by 3/4 by multiplying the numerator by 3 and the denominator by 4. That is 3/12. Also known as 1/4. 
Multiply 75 by 3/4 by dividing it by 4 then multiplying it by 3. That is 56 1/4. 
Add 56 1/4 and 1/4 together to get 56 1/2. 

Lastly, add together 56 1/2 and 602 2/3.
Convert the fractions to sixths.
56 3/6 + 602 4/6 = 659 1/6 miles
Hope this helps!
