Answer:

1,115.8937105551

Step-by-step explanation:

[ π x 40² ] =5,026.5482457437

[ 80 / 360 ] ft² =[,222] ft²

5,026.5482457437 X [,222] ft²= 1,115.8937105551 ft² 

A = [ π x 40² ] [ 80 / 360 ] ft² 

A = 1,115.8937105551 ft²

5. The volleyball team has a double-header on Friday. The probability that they
Nikolay [14]

Answer: 54.29%

Step-by-step explanation:

Given: The probability that they  will win both games is 38%.

i.e. P( both games will win) =0.38

The probability that they will win just the first game is  70%.

P(first game will win) = 0.70

To find : P(second game will win| first game will win)

Using formula: P(B|A)=\dfrac{P(\text{both A and B})}{P(A)}

So, P(second game will win| first game will win) = \dfrac{\text{ P( both games will win)}}{\text{P(first game will win)}}

=\frac{0.38}{0.70}\approx0.5429=54.29\%

Hence, the required probability = 54.29%

Given: AM = 8, AB = 5x +1 and M is the midpoint of AB, find x and AB<br> X=<br> AB=
NARA [144]

Answer:

x = 3

AB = 16

Step-by-step explanation:

Given: AM = 8, AB = 5x +1 and M is the midpoint of AB, the AM = MB

AB = 2AM

5x+1 = 2(8)

5x + 1 = 16

x = 16 - 1

5x = 15

x = 15/5

x = 3

Hence the value of x is 3

Since AB = 5x+1

AB = 5(3) + 1

AB = 15 + 1

AB = 16
