Amy is shopping for a new couch. She

finds one that she likes for $800, but

her budget is $640. How much of a

discount does she need in order to be

able to afford the couch?

Answers

Answer 1

Amy needs a discount of 20% in order to be able to manage to pay for the couch within her budget of $640.

To discover how much of a discount Amy needs to come up with the money for the couch, we can calculate the amount of the cut price that might carry the rate all the way down to her finances of $640.

discount = original rate - budget

discount = $800 - $640

discount = $160

So Amy wishes a discount of $160 for you to be able to find the money for the sofa. alternatively, we can calculate the proportion discount as follows:

percentage discount = (discount / original price) x 100%

percent discount = ($160 / $800) x 100%

percent discount = 20%

Therefore, Amy requires a discount of 20% in order to be able to manage to pay for the couch within her budget of $640.

Answer:

For Question 13 :∡ 1 = 130°; ∡ 2 = 50° ∡ 3 = 130°

For Question 14 :∡ 1 = 65°; ∡ 2 = 115° ∡ 3 = 65°

Step-by-step explanation:

Question 13:

There is multiple ways to solve those questions. However I will stick with the simple way.

1) We know that a straighteangle is = to 180°

2) Acording to the statment on step one we will say that ∡ 1 + the ∡ 50° = 180°

Resoectivelly

180° - 50° = ∡1

180° - 50° = 130°

∡ 1 = 130°

3) ∡ 2 + ∡ 1 = 180°

We already ∡ 1 from step 2, then

∡ 2 = 180° - 130°(∡1)

∡ 2 = 50°

4) ∡ 2 + ∡ 3 = 180°

∡ 3 = 180° -  50° (∡ 2)

∡ 3 = 130°

Question 14 1) We know that a straighteangle is = to 180°

2) Acording to the statment on step one we will say that

angle 1 + the angle  115° = 180°

Resopectivelly

180° - 115° = ∡ 1

180° - 50° = 65°

∡1 = 65°

3) ∡ 2 + ∡ 1 = 180°

We already∡ 1 from step 2, then

∡ 2 = 180° - 65°(∡1)

∡ 2 = 115°

4) ∡ 2 + ∡ 3 = 180°

∡ 3 = 180° -  115° (∡ 2)

Complete question :

Liz's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and regression line below show the relationship between how many hours students spent studying and their score on the test.

The fitted line has a slope of 15.

What is the best interpretation of this slope?

Answer:

C.)

The model predicts that the score will increase 15 points for each additional hour of study time.

Step-by-step explanation:

The slope of a regression line represents the rate of change :

From the formula :

Rise / Run = (y2 - y1) / (x2 - x1).

The slope is a Coefficient which shows how much the dependent variable changes per unit change in the independent variable.

Hence, for a slope value of +15, which is positive, meaning an increase ; then the score obtained will increase by 15 per additional unit increase in hour of study.

What is the measure of \angle b∠bangle, b?

Answers

Answer:

31°

Step-by-step explanation:

because angle a and angle b are complementary they equal 90 degrees in total

a+b=90

since angle a = 59°

59+b=90

so you use subtraction property of equality and subtract 59 from both side of the equal sign

59+b=90

b= 31°

A two digits number is 21 times the difference and 350% of the product of its digit. Find the quotient of the digit of number​

Answers

The number is 63, so the quotient is 2.

Two digit numbers divisible by 21:
21, 42, 63, 84

21: 2-1 = 1 * 3.5 = 3.5
3.5*2*1 = 7 but 7 does not equal 21

42: 4-2 = 2 * 3.5 = 7
3.5*4*2 = 28 does not equal 42

63: 6-3 = 3*3.5 = 13.5
3.5*6*3 = 63 :)

Check:
21(6-3)=21(3)= 63 :)
3.5(6)(3) = 21(3) = 63 :)

AKAJAXOSPAPXODAOAPA HELP

Answers

Answer:

He used 6 bananas at .50 which cost $3.00

12 oranges at .75 which cost $9.00 and

3 papayas at $1.25 which cost $3.75

Step-by-step explanation:

We can set up a system of equations using the information given.

b for banana, r for orange, p for papaya

b + r + p = 21. Also given r = 2b So substitute to simplify for calculating two unknowns:

b + 2b + p = 21 The number of items.

50b + 75(2b) +125p = 1575 The cost.

I multiplied everything by 100 to eliminate the decimals.

To solve by substituion, rewrite the first equation to get a value for p in terms of b

p = 21 - 3b

Substitute this value in the second equation and solve for b.

50b + 150b + 125(21–3b) = 1575

200b +2625 –375b = 1575 Subtract 2625 from both sides and combine the like terms:

–175b = 1575 –2625

–175b = –1050. Divide both sides by –175

b = 6

Substitute in the original equation to find the amount of each fruit:

b + r + p = 21

b = 6 bananas

r = 2b. 2(6) = 12 oranges. I used r so as not to mix up o with 0.

6 + 12 + p = 21

p = 21 –18

p = 3 papayas

Find the sum.
