Penny is making a model of a Ferris wheel that is 60 feet tall. The model is 15 inches tall. Penny is also
making a model of the sky needle ride that is 100 feet tall using the same scale. How tall is the model of
the sky needle?

Answers

The model of the sky needle will be 20 inches tall as the scale factor is 4.
Since the Ferris wheel model is in feet and inches, bring both measurements to inches, then divide the total height of the Ferris wheel by the height of the model, then you multiply the height of the sky needle ride by the quotient of the height of the Ferris wheel and the model of the Ferris wheel to get 7 inches

You can complete three-tenths of a task in an hour. Your friend can complete one-fifth of the same task in an hour. How long will it take to complete the task if you work together? Explain.
_______ hours.

Answers

Answer:

2 hours

Step-by-step explanation:

If you convert 1/5 to tenths it's 2/10.

If you add 2/10 and 3/10 you get 5/10 which would be how much off the task you got done in one hour.

Therefore you times 5/10 by 2 and you get 10/10 so the task is done and it took 2 hours.

An expression is shown below:
2x3 + 10x2 − 4x2y − 20xy

Part A: Rewrite the expression so the GCF is factored completely.

Answers

The answer is 52 I hope this helps you

The given expression can be rewritten as 2x(x²+5x-xy-10y).

The given expression is 2x³+10x²-2x²y-20xy.

What is GCF?

GCF stands for the greatest common factor. The greatest common factor of two numbers is the greatest number that is a factor of both of them.

Now, 2x³=2×x×x×x, 10x²=2×5×x×x, 2x²y=2×x×x×y and 20xy=2×x×x×y

Here, the GCF of all the terms is 2x.

So, the expression becomes 2x(x²+5x-xy-10y).

Therefore, the given expression can be rewritten as 2x(x²+5x-xy-10y).

Hayley has $155 in savings, and her brother Hank has $230. Hayley is saving $10 each week, and her brother is spending $15 each week. After how many weeks will their savings accounts have the same amount of money in them?

What is the best way to set up this word problem to solve?


15x+155=230+10x
15 x plus 155 is equal to 230 plus 10 x

155−15x=10x+230
155 minus 15 x is equal to 10 x plus 230

155+10x=230−15x
155 plus 10 x is equal to 230 minus 15 x

155−10x=230+15x

Please I need I will Brainliest!!!

Answers

Answer:

The Correct Answer is The 3rd one, Or C

Step-by-step explanation:

It will take 3 weeks

If its right mark me brainliest if its wrong report me.

Answer:

$155+$10x=$230-$15x

Step-by-step explanation:

weeks= x

$155+$10x=$230-$15x is the correct answer because hayley currently has $155 in her saving and you have to add the 10 dollars she saves each week which is 10x. On the other hand, her brother has $230 and spends $15 dollars every week so that is 15x.

What is the value of 9(4x - 4), when x=5?
Do all multiplication first, then solve the problem from left to right.

ILL GIVE BRAINLIET

Answers

I believe by asking you to do all multiplication first they are asking you to demonstrate the distributive property, this means we can distribute the 9 through the parenthesis by multiplying it by each part inside the parenthesis, this gives us:

36x - 36

now we can substitute 5 in for x to get:

36(5) -36

A teacher wants to choose a student at random. The teacher decides to choose the first person to walk through the classroom door at the start of the lesson.
a. Explain why this is not a good method.
b. Suggest a better method.

Answers

A. The method is not a good method because the student that walks through the door first is probably the student who always walks through the door first. This makes the choosing not random and makes it a biased choice.

B. The teacher should pulls sticks with the students names on it, or use a random name generator.

Answer:

It is not a good method because the first person to walk through the door should be rewarded for being on time and it is pretty much  that the first person to walk in is always the first to walk in  

They should have a  volunteer and make them do it step by step for other kids to see or if someone is late  make them do it

1)73 degrees
all the angles of a triangle add up to 180 degrees.
23+84= 107
180-107=73

2) 28 degrees
110+42= 152
180-152= 28

Explanation:

All sides in a triangle is equal to 180°
So whenever given two sides only, add them up, and subtract from 180. That will give you the missing sides length.
So 23 + 84 = 107
180 - 107 = 73
The missing side of the triangle is equal to 73°.

110 + 42 = 152
152 - 180 = 28°
The missing side of the triangle is equal to 28°.

Another example is:
100°, 40°
Front the missing side in this triangle.
100 + 40 = 140°
180 - 140 = 40°
The missing length is 40°
