O A. V120
O B. V118
OC. V123
OD. V115

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.

Answer:

y = 2x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + 2y - 12 = 0 ( subtract x - 12 from both sides )

2y = - x + 12 ( divide terms by 2 )

y = - [tex]\frac{1}{2}[/tex] x + 6 ← in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2

------------------------------------------

To find the x- intercept let y = 0 in the equation and solve for x

3x - 2(0) + 12 = 0

3x + 12 = 0 ( subtract 12 from both sides )

3x = - 12 ( divide both sides by 3 )

x = - 4

Then x- intercept at (- 4, 0 )

Then

y = 2x + c ← is the partial equation

To find c substitute (- 4, 0) into the partial equation

0 = - 8 + c ⇒ c = 0 + 8 = 8

y = 2x + 8 ← equation of perpendicular line

Answer:

c² = a² + b² - 2ab×cos(C)

c = 7.7

Step-by-step explanation:

we use the enhanced Pythagoras for general triangles :

c² = a² + b² - 2ab×cos(C)

c² = 16² + 10² - 2×16×10×cos(22) = 256 + 100 - 320×cos(22) =

= 356 - 320×0.92718... = 356 - 296.698... ≈ 59.3

c ≈ 7.7

as you can see, the "regular" formula of Pythagoras

c² = a² + b²

is derived from the fact that cos(90)=0.

Step-by-step explanation:

Answer:

Multiply the first equation by 15 (Answer D)

Step-by-step explanation:

Writing these equations symbolically, we have:

(2/3)x + (1/5)y = 6

(1/6)x - 3y = 8

Which number can she multiply the first equation by so that when the two equations are added together, the y term is eliminated?  After this multiplication, we should have +3y in the first equation; then 3y - 3y = 0 as desired.  The coefficient of the y term in the first equation is (1/5), whereas we want it to be +3.  

Multiplying the first equation by 15, we get 10x + 3y = 90.

Then our system is:

10x + 3y = 90

(1/6)x - 3y = 8

---------------------

(61/6)x = 98    (the variable y has been temporarily eliminated).

Answer:D

Step-by-step explanation:

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

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

37.5+37.5+15=90

75+15=90

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

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.

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:

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]

Answer:

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

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
