Because it’s showing that both the lines are 120

Answer:

Step-by-step explanation:

It shows 120 for both the sides of the angle, which makes it parallel.

B is wrong because they don't have the same angle measure.

C is wrong because they don't have the same angle measure.

D is also wrong, because it shows both the measures of angle A, and you don't know what angle B is.

simplify -6/5 divided by 2 2/5

Answers

Answer:

0.24or -1/2

Step-by-step explanation:

The simplified fraction of -6/5 divided by 2 2/5 is -1/2.

To simplify the expression -6/5 divided by 2 2/5.

First, let's convert the mixed numbers to improper fractions:

2 2/5 = (2 x 5 + 2) / 5

= 12/5

Now, we can rewrite the expression as:

-6/5 ÷ 12/5

When dividing fractions, we can multiply by the reciprocal of the second fraction. So, we have:

= -6/5 x 5/12

= -6/1 x 1/12

Multiply the numerators and denominators:

= (-6 x 1) / (1 x 12)

= -6/12

= -1/2

Therefore, the simplified fraction of -6/5 divided by 2 2/5 is -1/2.

Identify the slope, y-intercept, and write an equation (don't add spaces):

You and your friends go to the movies and buy a large bucket of popcorn containing 682 pieces of popcorn. As a group, you consume 40 pieces of popcorn every minute.

Answers

Slope intercept form: y = mx + b

Equation: 682 = 40x
Slope = 40 (or 40/1)
Y-intercept = 0

In this case,

y = the total
x = the amount of minutes
y-intercept = 0, since there isn’t a b in the equation.
slope = 40, because y = mx + b is 682 = 40x

This should be correct, unless there is missing information in the question.

Consume per min=40Popcorns be x

Equation of expression

$\\ \tt\hookrightarrow y=40x+682$

Compare to y=mx+b

Slope=m=40Y intercept=b=682

Answers

Here’s ur answer, if anything is unclear let me know I will correct it

Help pls. Also wdym this is to short yk why so long >:/

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.

Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.

Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.

Answers

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

The answer to the question is 0.6 gallons

Which fraction is easier to convert into a decimal?

11/18 or 43/50, explain

Answers

43/50 is easier because 50 is half of 100

Watch this

43/50. Since 50 is HALF of 100 so we multiply 2 by 50 which is 100. But since we multiplied by 2 for the denominator we have to do the same for the numerator so 43 x 2 is equal to 86.

So we get 86/100 which is 0.86

43/50 decimal 0.87

It's easier to turn into a decimal because both are bigger numbers and and closer to each other so it would be easier to divide

Match each quadratic function with the quadrant that its vertex lies in -

Answers

All of these quadratic equations are in vertex form, which makes it really easy to identify the vertex.

Vertex Form: f(x) = a(x - h)^2 + k

Vertex = (h, k)

As for the quadrants, it is dependent on the positive/negative signs of the x and y coordinates.

---Q1 = (+, +)

---Q2 = (-, +)

---Q3 = (-, -)

---Q4 = (+, -)

y = (x - 3)^2 - 2

Vertex = (3, -2)

Quadrant = Q4

y = (x - 3)^2 + 2

Vertex = (3, 2)

Quadrant = Q1

y = (x + 3)^2 + 2

Vertex = (-3, 2)

Quadrant = Q2

y = (x + 3)^2 - 2

Vertex = (-3, -2)

Quadrant = Q4

Answers

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship

Consider the standard form of an exponential function:

$y=a(b)^x$
How does changing the base number (inside the parentheses) change your graph?

Answers

Answer:

Step-by-step explanation:

Challenge 1

We have exponential decline if 0 b 1. As you move from left to right, the curve will get less steep.

If b is greater than 1, exponential growth is present, and the curve slopes upward from left to right.

Examples include exponential decline (y = 2(0.5)x) and exponential growth (y = 2(1.2)x).

Remember that b cannot be negative.

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

Challenge 2

In the general template provided, enter x = 0.

y = a(b)^x

y = a(b)^0

y = a(1) (1)

y = a

When x = 0 is plugged in, the result is y = a.

The curve is therefore on the point (0,a). The y intercept appears here. It is the point when the curve veers off the y axis. The y intercept is altered if the value of "a" is altered.
