Hello!

Question 1:
We have to put the ratio of the volumes

It is 27:125 ratio

This can be put as 27/125

We can multiply this by 63 to get the unknown surface area

This gives us 292

The answer is 292in^2

Question 2:
We have to find the ratio of the radius

3.1 : 6.2

We can see that they multiplied the first balloon by 2 to get the second

To find the missing volume we do 125 * 2 = 250

The answer is 250cm^3

Hope this helps!

If SU and VX are parallel lines and mUTR = 115°, what is mSTW?

grandymaker [24]

Answer:

m STW = 115°

Step-by-step explanation:

here, SU || VX

m STW = m UTR

( vertical opposite angles )

Hence, STW = 115°

Assuming that all the grapes have the same probability of being randomly picked:

a) 0.11
b) 0.24

<h3>How to find the probabilities?</h3>

We know that there are 8 green grapes and 15 red grapes on the bowl, so there is a total of 23 grapes.

a) Here we need to find the probability that both grapes are green. Remember that the probability of getting a green grape is equal to the quotient between the number of green grapes and the total number of grapes, this is:

P = 8/23

But then he must take another, because he already took one, the number of green grapes is 7, and the total number of grapes is 22, so for the second grape the probability is:

P' = 7/22.

The joint probability is the product of the two individual probabilities:

prob = (8/23)*(7/22) = 0.11

b) For the first green grape we know that the probability is:

P = 8/23

Then he must get a red grape. There are 15 red grapes and 22 grapes in total, so the probability is:

P' = 15/22

Then the joint probability is:

prob = (8/23)*(15/22) = 0.24
