Well if you notice, 48, x, and x are all on the same line, so they must add up to equal 180 degrees. So...

2x + 48 = 180
2x = 132
x = 66

So each x is equal to 66 degrees. Now we know the triangle is a right triangle, and the sum of all interior angles must be equal to 180 degrees for a triangle. So...

66 + 90 + z = 180
156 + z = 180
z = 24

Z equals 24 degrees! I hope this helps!

Answer:

9x + 5y = 29 ........... (1) and

3x + y = 7 ........... (2)

Each game of ping pong requires 1 number of token and each game of pinball requires 4 number of tokens.

Step-by-step explanation:

Let, each game of ping pong requires x number of tokens and each game of pinball requires y number of tokens.

So, from the given conditions we can write

9x + 5y = 29 ........... (1) and

3x + y = 7 ........... (2)

Now, solving equations (1) and (2) we get,

9x + 5(7 - 3x) = 29

⇒ 35 - 6x = 29

⇒ 6x = 6

⇒ x = 1 token.

Now, putting x = 1 in equation (2) we get,

3 + y = 7

⇒ y = 4 tokens.

So, each game of ping pong requires 1 number of token and each game of pinball requires 4 number of tokens. (Answer)

nika2105 [10]

The volume of cone is calculated by the formula $V= \frac{1}{3} \pi R^2H$ , where H is a height of cone and R is a radius of the bottom.
In your case, R=3 cm and R=7 cm. Then $V= \frac{1}{3} \pi* 3^2*7= \frac{63\pi}{3} =21\pi$ .
Answer: The volume of candy is 21π.

A decorator wants to line the bottom with through George with paper if the bottom each drawer measures 36“ x 20“ how many square

amm1812

The amount of paper that are needed to line the bottom of 3 drawers with paper is equal to 2,160 square inches.

<h3>How to determine the amount of paper?</h3>

First of all, we would calculate the area of the bottom of each drawer as follows:

Area = length × width

Area = 36 × 20

Area = 720 square inches.

Next, we would multiply this area by 3:

Total area = 720 × 3

Total area = 2,160 square inches.

What's the mean, median, and mode of 3, 5, 1, 5, 1, 1, 2, 3, 15.

lara [203]

<h3><em>Answer:</em></h3>

<em>Median = 3</em>

Step-by-step explanation:

first let’s arrange the numbers from least to highest:

1 , 1 , 1 , 2 , 3 , 3 , 5 , 5 , 15

=====================

The median is the number that’s comes in the middle of the data set ⇒ median = 3 ( the fifth number in the data set)

1 , 1 , 1 , 2 , <u>3</u>, 3 , 5 , 5 , 15

________________________

The mode is the number that repeats the most ⇒ mode = 1 (repeated 3 times)

____________________________________

$\text{the mean} =\frac{1+1+1+2+3+3+5+5+15}{9} = \frac{36}{9}=4$
