Answer:

$480

Step-by-step explanation:

multiply the normal price $600 by 20 then divide it by one hundred

the discount is $120

the sales price is subracting the discount of $120 from the original price of $600 then get $480 as the sales price.

Answer:

Step-by-step explanation:

Method 1:  Subtract 20% from 100%, obtaining 80%, and then multiply the regular price ($600) by the decimal equivalent 0.80.  We get $480 as the sale price.

Method 2: Calculate the amount of the discount by multiplying $600 by 0.20, obtaining $120.  Then subtract this discount from the regular price, $600, obtaining $480.

Answer:

181/13 =w

Step-by-step explanation:

2w+2019 = 15w + 1838

Subtract 2w from each side

2w-2w+2019 = 15w-2w + 1838

2019 = 13w + 1838

Subtract 1838 from each side

2019 -1838 = 13w

181 = 13w

Divide each side by 13w

181/13 = 13w/13

181/13 =w

Answer:

A = 61

Step-by-step explanation:

Complementary angles add to 90 degrees

A+B = 90

A +29 = 90

A = 90-29

A = 61

Answer:

∠A = 61°

Step-by-step explanation:

We know that sum of both angles of complementary angle is 90°.

∠A + ∠B = 90°

∠A + 29° = 90° ... (∠B = 29° - given )

subtract 29° from each side

∠A + 29° - 29° = 90° - 29°

∠A = 61°

Answer:

$19.99

Step-by-step explanation:

There are 12 months in a year, so in 2 years, there are 24 months.

Find how much each payment will be by dividing the cost by 24:

479.76/24

= 19.99

So, each payment will be $19.99

Complete question is;

Craig went to an auction and bought five different items. Use the clues below to determine the price he paid for each item.

1. the chair was the most expensive item, which sold for $95.

2. The range of the prices of the five items was $75.

3. The stereo was the least expensive item.

4. Craig bought the TV for $25.

5. The video game player was $20 more than the TV.

6. The bed was $60 more than the stereo.

Answer:

Cost of chair = $95

Cost of stereo = $20

Cost of TV = $25

Cost of video game player = $45

Cost of bed = $80

Step-by-step explanation:

We are told the chair was the most expensive item which was $95.

the range of the prices of the five items was $75. This means;

Highest price - lowest price = $75

Since highest price is $95, then lowest price = 95 - 75 = $20

stereo is the least expensive item. Thus, stereo will cost $20.

TV was bought for $25

video game player was $20 more than the TV. Thus, video game player cost = 25 + 20 = $45

Bed was $60 more than stereo. Thus,

Cost of bed = $20 + $60 = $80

A

Step-by-step explanation:

Corresponding parts of similar triangle have the same proportions

Answer: A)  [tex]\frac{AB}{XY} =\frac{AC}{XZ}[/tex]

Step-by-step explanation:

OK so if a figure is a dilation of another figure that means that is has the same angles but the sides are going to be smaller or bigger. Even though the sides are a different size they are proportional. So if I divided the length of AB over XY I'd get 5 since that is the scale factor. If I did that with AC over XZ I'd get 5 again because that is the scale factor. That's because they were proportional. Let's say this wasn't a dilation and AB over XY was 5 but AC over XZ was 4 that would mean it isn't proportional because AB would be 5 times bigger but XZ is only 4 times bigger.

Answer:

Step-by-step explanation:

perimeter of rectangle=a+b+c

=3x+3x+15

=6x+15

if perimeter of rectangle is 90,

perimeter=a+b+c

90=3x+3x+15

90-15=6x

75/6=x

12.5=x

Answer:

X=12.5

Step-by-step explanation:

3x+3x+15

If it equalls 90 then write it as 6x+15=90

Now isolate X.

6x+15=90

6x=75

x=12.5

CHECK UR WORK

(3*12.5)+(3*12.5)+15=90

37.5+37.5+15=90

75+15=90

90=90

Answer:

The total discount is 51%.

Step-by-step explanation:

A 30% discount is applied to the price of a product and another 30% discount to the new price. What is the total discount?

Let the price is p.

After first discount, the price is

= 70% of p = 0.7 p

After second discount, the price is

= 70% of 0.7 p

= 0.7 x 0.7 p

= 0.49 p

So, let the total discount is d.

[tex]d = \frac{p - 0.49 p}{p}\times 100 = 51%[/tex]

Given:

A figure of a rectangular prism with length l, width w and height h.

To find:

The surface area of the rectangular prism.

Solution:

The product of twice of the length l and the width w is:

[tex]2\times l\times w=2lw[/tex]          ...(i)

The product of twice of the length l and the height is:

[tex]2\times l\times h=2lh[/tex]           ...(ii)

The product of twice of the width w and the height h is:

[tex]2\times w\times h=2wh[/tex]       ...(iii)

The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:

[tex]A=2lw+2lh+2wh[/tex]

[tex]A=2(lw+lh+wh)[/tex]

Therefore, the required expression is [tex]2(lw+lh+wh)[/tex].

Answer:

Step-by-step explanation:

given.quesion.

The length of a rectangle is decreased by 25% and the width has increased by 40% calculate the percentage change in the area of the rectangle

to. find.

area of the rectangle

given

decreased. 25•/•

increased.40•/•

solusion

Length = L

Breadth = B

Original area = L x B

New area = A = L x (1 - 25%) x B x (1 + 40%)

A = L x B x 0.75 x 1.40 = L x B x 1.05

Therefore the area of the rectangle has increased by 5%.

Answer:

AAS

Step-by-step explanation:

Answer:

Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.

The ASA rule states that:

If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.

Angle-Angle-Side (AAS) Rule

Angle-side-angle is a rule used to prove whether a given set of triangles are congruent.

The AAS rule states that:

If two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.

In the diagrams below, if AC = QP, angle A = angle Q, and angle B = angle R, then triangle ABC is congruent to triangle QRP.

C. strong negative correlation

Step-by-step explanation:

A hotel manager records the number of bookings made at various prices during July.

What type of correlation does the graph show?

A. strong positive correlation

B. weak positive correlation

C. strong negative correlation

D. weak negative correlation

Correlation is a statistical measure used to measure the relationship that exists between two variables.

1. Positive correlation : it mean that the two variables move in the same direction. If one variable increases, the other variable also increases.

For example, there should be a positive correlation between quantity supplied and price

When there is a positive correlation, the graph of the variables is upward sloping

2. Negative correlation :  it mean that the two variables move in different direction. If one variable increases, the other variable decreases.

For example, there should be a negative correlation between quantity demanded and price

When there is a negative correlation, the graph of the variables is downward sloping

3. Zero correlation : there is no relationship between the variables

it would be 10

Step-by-step explanation:

once you solve the problem which should equal up to 3000 then you would divide 30000÷3000 and get the answer of 10

Answer:

Step-by-step explanation:

Divide the numbers first because that's the easy part and we've been dividing since like 5th grade.

1.6/.2 = 8. Now for the exponents.

When you divide like bases, you subtract the exponents. Our bases are both 10's, so they are like. Subtracting the exponents gives us 10³. So the answer is 8 × 10³, choice B.
