A school bus passes through an intersection with a traffic light in the morning on its way to school and in the afternoon on its way home. The following data was collected during a school year: The bus passed through the intersection 310 times. 70 green lights were in the morning. There were 30 more red lights in the morning than in the afternoon. There were a total of 140 red lights.

Step-by-step explanation:

The first important details are given at the start, where the beginning amount of snow is 12 inches. This is a positive number.

Then, the next sentences tell us that the snow melts at a pace of 2 inches for an x number of days.

This can be represented by -2x because the word "melts" indicates a negative value.

From this, the equation can be made :)

Answer:

a. 150 degrees

b. 210 degrees

c. 12π

d. 5π

e. 7π

f. 36π

g. (I'm assuming the shaded region is CAB) 15π

Answer:

x = 1

Step-by-step explanation:

Note that the x-coordinates of the two given points are identical.  This tells us immediately that the line is a vertical one whose slope is undefined.

The equation of this line is x = 1.

Answer:

∠WXY=72°

Step-by-step explanation:

2X-2=70+X

2X-X=70+2

X=72° ⇒ ∠WXY=72°

Answer:

Step-by-step explanation: B

The tables of ordered pairs representing relations that are functions are: A and C.

If a table of ordered pairs of a relation has each x-value relating to exactly one y-value, then the relation is a function.

Table B and D do not apply to this rule. Table A and C have each of its x-values paired with exactly one y-value.

Therefore, table A and C represent functions.

Step-by-step explanation:

−4x+5−13x+39=180

Step 1: Simplify both sides of the equation.

−4x+5−13x+39=180

−4x+5+−13x+39=180

(−4x+−13x)+(5+39)=180(Combine Like Terms)

−17x+44=180

−17x+44=180

Step 2: Subtract 44 from both sides.

−17x+44−44=180−44

−17x=136

Step 3: Divide both sides by -17.−17x

Answer:

they are parallels

Step-by-step explanation:

they have the same slope but different y intercepts so they are parallel

Answer:

Parallel

Step-by-step explanation:

First, you should put the second equation in slope-intercept form, it would be y=3x+8.

If two lines are parallel they will have the same slope. If two lines are perpendicular the slopes will be the negative reciprocals of each other. The slopes of these two lines are the same so they are parallel.

The correct option is D, the value of the missing side x is 5.

If the two prism are similar, then there is a scale factor that when multiplied by the dimensions of the blue prism, we get the dimensions of the green one.

If that scale is k, then we can write:

3k = 15

Solving for k:

k = 15/3

k = 5

Now, the correspondent side to the one that measures x, has a measure of 1 unit (in the blue prism), then the value of x is:

1*k = x

1*5 = x

5 = x

The correct option is D.

Answer:

x = -2

y = -4

Step-by-step explanation:

The way systems of equations  work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*

so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.

that would leave

5x = -10

divide both sides by 5

x = -2

Now that we know x = -2, we can plug in -2 into one of the equations to find y.

2 ( -2)  + 5y = -24

-4 + 5y = -24

-4 + 4 + 5y = -24 + 4

5y = -20

y = -4

x = -2

y = -4
