# The length of each of the two congruent sides d an isosceles triangle is 2x + 3. The length of the third side is 2x. It’s perimeter is 36 cm. Solve for x and then find the length of all three sides

## Answers

Answer 1
Answer: X=5 so the congruent sides are 13cm and the last one is 10 cm.

I believe the best answer is the first option; the cube of the difference of 5 times the square of y and 7 divided by the square of 2 times y.

Answer:

The cube of the difference of 5 times the square of y and 7 divided by the square of 2 times y.

Step-by-step explanation:

The give expression is:

In words, this expression would have all these statement referring to each operation:

1. The cube of the difference, because the difference is inside the cubic power.
2. Of 5 times the square of y and 7, because these are the terms that are being subtracted.
3. Divided by, because the expression described before is in a quotient.
4. The square of two times y, because the both factor are inside the squared power.

Therefore, the first statement is correct.

Assume that a hat contains four bills: a \$1 bill, a \$5 bill, a \$10 bill and a \$20 bill. Two bills are to be selected at a random with replacement. find the probability that a) both bills are \$1 bill if the first selected is a \$1 bill
b) both bills have a value greater than a \$5 bill if the second bill is a \$10 bill

### Answers

The probabilities are:

a) 1/16

b) 1/8.

How to find the probabilities?

We assume that all the bills have the same probability of being randomly selected.

a) Then the probability of randomly selecting a \$1 bill is equal to the number of \$1 bills on the hat divided by the total number of bills.

There is one \$1 bill on the hat, and 4 bills in total, so the probability is:

p = 1/4.

Then you return the \$1 bill to the hat and want to draw it again, with the same probability as before.

q = 1/4.

The joint probability is the product of the individual probabilities, so we have:

P = p*q = (1/4)*(1/4) = 1/16.

b) There are 2 bills that have a larger value than \$5, then the probability for the first draw is:

p = 2/4

For the second draw, we must get the \$10 bill, and the probability of getting it is:

q = 1/4.

The joint probability is:

P = p*q = (2/4)*(1/4) = 1/8.

Answer:

a)1/4

b)1/2

Step-by-step explanation:

a) The selection is with replacement, then we already have 1 \$ bill and in the hat again the four bills. What is the probability  of select 1\$ bill ? well it is 1/4.

The point here is,  replacement condition make the second trial totally independent of the first one

b)Following the same reasoning now we have selected a 10 \$ bill, and we have two possibles positive outcome a 10 \$ and a 20 \$ bill and a total of 4 outcomes th th probability is 1/2

What are two addedns that will equal 1/3

### Answers

Well you can change 1/3 to 2/6, since you can multiply the numerator and denominator by the same number and the fraction will still be the same.

With 2/6, you can divide by 2 to get 1/6 and 1/6.

So addends are 1/6 and 1/6.
