Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.

Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct? Explain your thinking.

Answers

Answer:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

The measures of the angles of △ABC are given by the expressions in the table.

Angle Measure
A ​(6x−1)°​
B 20°
C (x + 14)°
What are the measures of angles A and C?

Answers

Answer:

First You add all given angles up to equal 180 to give you x then you plug x into equations

Step-by-step explanation:

A= 125 degrees

C= 35 degrees

Answer:

Angle A = 125°

Angle C = 35°

Step-by-step explanation:

This is the equation you would have to solve:

Angle A + Angle B + Angle C = 180°

Fill in the values given:

(6x-1)° + 20° + (x+14)° = 180°

The parentheses don't really matter here. Go on to combine like terms. This gives you:

7x + 33 = 180°

Solve for x. Subtract 33 on both sides. This gives 7x = 147. Divide both sides by 7. This gives x = 21.

Now, go back and fill in 21 for x in the expressions for angles A & C.

Angle A:

6(21) - 1 = 125°

Angle C:

21 + 14 = 35°

You can check your answers using the first equation I mentioned:

Angle A + Angle B + Angle C = 180°

125° + 20° + 35° = 180°

This is a true equation. Therefore, the final answers are:

Angle A = 125°

Angle B = 20°

Angle C = 35°

There will be an estimated amount of 1125 faulty souvenir tokens.

Step-by-step explanation:

Hi!

So, let's do this problem out.

So we for every 400 tokens, 3 are faulty

Let's write that in a ratio

3:400

Ok, great!

So, now we know that:

3:400 = x:150,000

We can set up a percent proportion

[tex]\frac{3}{400} =\frac{x}{150,000}[/tex]

To find x, we do:

[tex]x=\frac{3*150,000}{400}[/tex]

[tex]x=\frac{450,000}{400}[/tex]

[tex]x=\frac{4,500}{4}[/tex]

[tex]x=1125[/tex]

There will be an estimated amount of 1125 faulty souvenir tokens.

Which numbers have an absolute value of 4?(you can pick more than one)

4
-4
2
8

Answers

Answer:

4 and -4

Step-by-step explanation:

absolute value is always going to be positive and the overall value will only change if it is negative. so the "|4|" (absolute value of 4) is the same as "|-4|" (absolute value of negative 4)

You can pick 4 and -4. Absolute value is the distance from 0 on a number line. So if I have a 2 on the number line, the amount of space from the 0 is 2. If I have a negative 9 on a number line then the absolute value is positive 9. A absolute value is always positive, even if the number is negative. Hope this helps!
