Solve for x in the diagram below.

Solve For X In The Diagram Below.

Answers

Answer 1

Answer:

x = 40

Step-by-step explanation:

the line is 180 and there is already a target that is 100

so both x are 40

Answer 2

Answer:

x=40⁰

Step-by-step explanation:

Since a half a circle is 180⁰ and you already have 100⁰. Subtract 180⁰-100⁰ which gives you 80⁰ now divide that by 2 because you are looking for 2 x's which your answer is x=40⁰

The answer is 585

Because if you multiply 13 by 9, you get 117, and if you multiply 117 by 5, you get 585.

Answer:

9 flights = 13 steps x 9

everyday

9x13= 117 (117- how many steps she walks in a day)

Number 1 is 12% and number 2 is also 12% please trust me and mark me brainliest

pls answer all 3 parts

Answers

Answer:

a. 14

b. 1

c. 2

Step-by-step explanation:

If there are 4 one point questions and 5 two point questions, then 5 multiplied by two is 10 and adding it to 4 is 14. The quiz would be 14 points total. If you scored 87.5% on the quiz then you would know that you got 12 of the questions correct and you would know that by finding 87.5% of 14 which the equation to do so would be 87.5/100= 0.875, then 0.875* 14= 12.25. If you round 12.25 to the nearest whole number then it's 12. And since you got all the 1 point questions right, then you must of gotten 1 two point question wrong.

I hope this helps!

Annie went bowling. It cost $3 to rent shoes, plus $4 for every game that she played. She spent $11 total. How would you represent this situation using an equation, and using algebra tiles?

Answers

Answer:

Step-by-step explanation:

3+4g=11, subtract 3 from both sides

4g=8, divide both sides by 4

g=2, so two games were played

S= means shoes
G= means games

Explain how precipitation happens. Use complete sentences and give at least two supporting details​

Answers

Answer:

Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. ... Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough, they fall to the Earth.

Step-by-step explanation:

the sun evaporates the water from a stream or some type of water source and it then gets collected  into the clouds and then condensation and the last step is when the water is too heavy so the clouds release it and that is called precipitation. hope this helps.

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.

Answers

Answer:

U first need to find out the total number of people

22+28

50

and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator

22/50

And now to make it into % we need to ALWAYS multiply the fraction by 100

22/50 x 100

44%

Hope it helps

Answer:

44 %

Step-by-step explanation:

okay so 100% is equal to the whole team or 50 swimmers

100% = 50 swimmers

to find out how much one swimmer is would be to divide the 100% by the total of swimmers.

100% / 50 swimmers

2% = 1 swimmer

so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.

2 x 22 = 44
