You went to the store to buy a gift for your friend. Jeans are 20 dollars (what a deal) so you buy one for yourself and your friend. Then you see this really cute top and you want to match with your friend, so you get two of those too.

The total on the bill is $110.

While walking to your car, you lose the receipt.

When you give your friend the gift, she is excited. But says you spent too much money on her! She wants to pay you back for the shirt, but you can't remember how much it cost

What is the length of

saveliy_v [14]

Answer:

17 units

Step-by-step explanation:

Because the triangle is isosceles, 2 of its sides are congruent; namely, the two sides that are opposite of the 2 congruent angles are contruent.

Because of the reason stated above, we can see that AC is congruent to BC, meaning that:

x+9=2x-8

-x -x

9=x-8

+8 +8

17 = x

Notice that BC is equal to x, so 17 is our final answer.

What is the measure of each angle of a regular 24-gon? If necessary, round to the<br> nearest tenth.

Butoxors [25]

Answer:

165°

Step-by-step explanation:

Find the interior angle measure by using the formula, ((n - 2) x 180°) / n

Plug in 24 as n:

((n - 2) x 180°) / n

((24 - 2) x 180°) / 24

(22 x 180°) / 24

3960 / 24

= 165

So, the measure of each angle is 165°

When two dice are rolled and the sum of the outcomes are taken, the sample space is:

<u>Outcome Frequency</u>

2 1

3 2

4 3

5 4

6 5

7 6

8 5

9 4

10 3

11 2

12 1

The outcome 7 has the highest frequency of 6

This means that the turtle 7 has the highest chance of winning the race
