Answer: The answer is B. (A and D)

Step-by-step explanation: The answer is that because (A) and (D) both are right angles and the first step is cross out the Abtuse sorry if i spelt wrong. Then your left out with two right angles and in simplest form d and a equal $\frac{1}{2}$ . plz mark brailiest! -Cyrusskywalker.

Four students are running for class president: liz, sam, sue, and tom. the probabilities of sam, sue, and tom winning are 7⁄25 ,

Natali5045456 [20]

First, we need to convert all the fractions to have the same denominator. 10 and 25 are both multiples of 100, so 100 would be appropriate.

Sam has a 7/25 chance. Because we want ?/100, something needs to change. To get from 25 to 100, you need to times 25 by 4, right? So, do the same with the 7.
7 x 4 = 28. Therefore Sam has a 28/100 chance.

Sue has 3/10. Using the same method, we can see that 3 needs to be multiplied by 10 (because 10 times 10 = 100). So Sue has a 30/100 chance.

Tom is already in the fraction we like, so just keep this as 21/100.

Now, add 28/100, 30/100 and 21/100 to get 79/100.

Because won of them will get the role of class president, we know that the probability adds to 1. To get a full probability (100/100, or 1), what needs to be added to 79/100?

Another way of going about this is 100/100-79/100. The answer is 21/100

The probability of Liz winning is 21/100.

Let me know if this is still unclear, I would be more than happy to explain in more detail if necessary :)

An interior angle of a regular polygon has a measure of 135° how many sides does it have

butalik [34]

8 sides

the exterior angle = 180° - 135° = 45° ( exterior/ interior are supplementary )

the sum of the exterior angles of a polygon = 360°
