Answer:

\frac{1}{45} chance to grab both $20 bills

Step-by-step explanation:

There are ten bills in total.

The probability that the first dollar she picks is a twenty-dollar bill is 2/10 because she can pick either of the two twenty-dollar bills out of the ten in her wallet. Next, we need to pick the second bill. There are nine bills left, and only one is a twenty-dollar bill. The probability of choosing a second dollar bill is 1/9.

(2/10)*(1/9)=2/90=1/45

Whats an equation that make x=31 ? like in other words give me an equation where it leads down to 31
MrRa [10]
Sure, that's easy! Here's one

5x + 7 = 162

If I wanted to solve this equation, I would break it down. I'd subtract the result (162) by 7

162 - 7 = 155.

From there I just divide that by 5!

155 / 5 = 31

There it is! Ultimate proof that x is in fact 31!

ozzi

Answer:

Estimate the value of pi =3.14

Step-by-step explanation:

The diameter of the circle base of a storage container 18.8m

The diameter of the circle 'd' = 2r

Given data  'd' = 2r = 18.8m

The circumference of the circle = 2πr

Given data of circumference of the circle = 59 m

given        2πr = 59

                2r(π) = 59

                18.8 π = 59 ( by using 2r =18.8)

                  π = 59/18.8

                   π  = 3.13829

                    π  = 3.14

<u>Conclusion</u>:-

Estimate the value of pi =3.14
