Answer:

9 in, or B

Step-by-step explanation:

We can easily apply the Pythagorean Theorem to this. You could either realize that this is a 3-4-5 Pythagorean triple or do the math by hand.

We start off by setting up the equation 12² + x² = 15². Simplifying, we get 144 + x² = 225, and then x² = 81 after subtracting 144 from both sides. Thus, the square root of x is 9, and so the answer is 9 inches.

Answer: B

Step-by-step explanation: You have to make sure the two small sides add up to be greater than the biggest side( in this case 15in)

12+9=21, 21>15 therefore 9 would work!

I eliminated C and D using only visual clues

why 27 is a no-go: if we did it the other way around where 27 is the biggest number, it would be 12+15=27, 27=27 *therefore since 27 is equal to 27 the three sides would not make a triangle*

why 19 is a no-go: if we did <em>this </em>the other way around where 19 is the biggest number, it would be 12+15=27, 27>19. *visual part* Although this seems like it would also work, does <AX really look like it's bigger than <WX or <AW XD

Add up all.

Yards = 29 + 55 + 13 = 97

Feet = 2 + 1 + 1 = 4

PLEASEEEEEEEEEEEEEEEEEEEEEE Edgar rolls two six-sided number cubes. What is the probability that he rolls a 2 on
frutty [35]

Answer:

The probability that he rolls a sum of 9 given the sample space is . 9/36, or 1/4.

What is the probability?

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that he rolls a sum of 9 = cubes that have a sum of 9 / total number of cubes

9/36 = 1/4

Using simple interest, the investment will be worth;

= 24 * (1 + 0.06* 390)

= $585.60
