Answers

Answer 1
It’s 80 because
180 - 130 because 180 because that is what a triangle equal to 180 I got 50 the triangle is a isosceles triangle and I know two of the angles are the same degrees so 50+ 50 is 100 I minus that to 180 and got 80

D- 42

It needs to equal 180, and 180-138 is 42

Answer:

The answer is D: 42

Step-by-step explanation:

Angle 7 and angle 138 are supplementary and must add up to 180

Angle 7 is congruent to angle 6 through CPCTC (Corresponding Parts of Congruent Triangles are Congruent)

Angle 7 and 6 are corresponding angles

you must find angle 7 becasue Angle 7= Angle 6

angle 7=x

138-x=180

solve for equation you get

x=42

Angle 7 = 42

so that means that Angle 6 is 42

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

The equation would be 130% x N = 20.8

To solve you would have to switch the equation around and to do that you would divide. 130% is the same as 1.30 or 1.3

20.8 ÷ 1.3 = 16

N = 16

Write the equation of the line perpendicular to y=4x+2 and passes though the point (1,1).

Answers

Answer:y=-1/4x+5/4

Step-by-step explanation:

Perpendicular means the slope has to be the negative reciprocal.

Since the slope is currently 4, the perpendicular slope is -1/4.

It also has to pass through the point 1,1 , so you just plug x in which will be

1*-1/4=-1/4. from 1 to -1/4, its 5/4, so that's your b in y = mx+b

The equation will then be y=-1/4x+5/4

C) 18

Step-by-step explanation:

All you have to do is solve the equation.

2.25x + 5 = 45.50 (subtract 5 on each side)

2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)

x = 18

40.50/2.25 = 18

Answer:

18 Miles

Step-by-step explanation:

If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.

Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

3x - 1 = x + 5

2x = 6

x = 3.

On solving the logarithmic equation, we find that x = 3.

Which graph best represents the equation y=2x+5?

Answers

Answer:

B?

Step-by-step explanation:

The graph y = 2x + 5 can be represented by the image attached below.

What is a graph?

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, An equation y = 2x + 5, we can graph this by assuming some arbitrary values of 'x' that correspond to some arbitrary values of 'y'.

When x = 0, y = 5.

x = 1, y = 7 ⇒  (1, 7).

x = 5, y = 15 ⇒ (5, 15).

x = - 5, y = - 5 ⇒ (- 5, - 5).

x = - 2, y = 1 ⇒ (- 2, 1).

Witch expression is equivalent to 1/5(150x - 80y + 50 - 50x- 25y + 20)?

Answers

Answer:

20x - 21y + 14

Step-by-step explanation:

1/5(150x - 80y + 50 - 50x- 25y + 20)

Step 1 - Distribute

1/5 • 150x = 30x

1/5 • (-80y) = -16y

1/5 • 50 = 10

1/5 • (-50x) = -10x

1/5 • (-25y) = -5y

1/5 • 20 = 4

Step 2 - Combine Variables

30x - 10x = 20x

-16y - 5y = -21y

10 + 4 = 14

Step 3 - Arrange the Set of Numbers

Are the triangles PQR and RST similar why or why not?

Answers

Answer: The triangles are similar

======================================================

Explanation:

The square markers show that

angle RPQ = angle RST = 90 degrees

So that's one pair of congruent angles. Another pair of congruent angles is what you see in the diagram below. The angles marked in red are congruent alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.

Since we have two pairs of congruent angles, we can use the AA (angle angle) similarity theorem to prove the triangles congruent.

Answer:

Triangle PQR and RST are both right triangles but they do not share the same  side lengths. They also share the same point R, so I would say that they are similar only because they are both right triangles.

An electronics company is changing its internet advertising from a banner advertisement to a pop-up advertisement. The cost of the banner advertisement in dollars is represented by the function C(n) = 0.30n + 5.00 where 'n' is the average number of hits per hour and $5.00 is just a flat-rate cost.


1.) The cost of the pop-up advertisement will double the cost per hit. The equation for this new cost function will be D(n) =


2.) This change does/does not shift the function vertically and/or horizontally.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Cost function of banner advertisement:

C(n) = 0.30n + 5.00

n = average number of hits per hour

5 = flat rate

From the function, C(n), the cost per hit is the slope value of the function ; which is 0.30

1.) If the cost of pop-up advert will double the cost per hit, the cost function for pop-up advert will be :

D(n) = 2(0.30n) + 5

D(n) = 0.60n + 5.00

B.) This change in cost per hit has resulted in change in slope which is defined as :

[Rise / run = vertical change / horizontal change].

Hence, both vertical and horizontal change has occurred.
