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.

Answer:

Lines C and D

Step-by-step explanation:

Both lines C and D are negative, and they both have the same slope. in order to find the slope you use rise over run; in this case, you go down 2 over left 1. C and D are the only lines that use that slope; therefore, they are the answers.

Answer:

x = 12

ST = 23 units

SU = 23 units

TU = 23 units

Step-by-step explanation:

For an equilateral triangle, all the angles are equal. Also, all the sides are equal.

Hence given that the sides ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x

ST = 2x - 1

SU = 5x - 37

TU = x + 11

Since ST = SU = TU

2x - 1 = 5x - 37

collect like terms

37 - 1 = 5x - 2x

36 = 3x

Divide both  3

36/3 = x

x = 12

Therefore

ST = 2x - 1 = 2(12) - 1 = 23 units

SU = 5x - 37 = 5(12) - 37 = 23 units

TU = x + 11 = 12 + 11 = 23 units

Answer:

400 girls.

480 boys.

Step-by-step explanation:

If the number of girls is x then the number of boys is 1.2x, so we have:

x + 1.2x = 880

2.2x = 880

x = 880/2.2

= 400.

Girls = 400, boys = 1.2*400 = 480.

Answer:

what are the answer choices

Step-by-step explanation:

Answer:

That's like 20 feet probably

Step-by-step explanation:

Okay so the distance between Tom and Jaime is the height of the triangle (South is directly down) (A=15 yards)

The distance between Tom and Ladonna is the base of the triangle (since Ladonna is west of Tom) (B is unknown)

The hypotenuse is the distance between Jaime and LaDonna (C=25 yards)

1. So 15^2 plus b^2 equals 25^2

2. 225 plus b^2 equals 625

3. Subtract 225 from both sides (b^2=400)

4. Find the square root of both sides.

5. B= 20 yards

Answer:

x=20

Step-by-step explanation:

bc 25 divided by 10 is 2.5 so you just multiply 8 by 2.5

Answer: X= 20

If solving for x

Step-by-step explanation:  

x/25= 8/10    

1= reduce the fraction to x/25= 4/5

2= cross multiply 5x=100

3= divide both sides X=20

Answer:

Step-by-step explanation:

1. The cube root is found by dividing the exponents by 3.

  [tex]\sqrt[3]{27a^{12}}=(3^3\cdot a^{12})^{\frac{1}{3}}=3^{\frac{3}{3}}\cdot a^{\frac{12}{3}}=\boxed{3a^4}\qquad\text{matches d}[/tex]

__

The factoring of the difference of cubes is ...

  a³ -b³ = (a -b)(a² +ab +b²)

Here, we have a=r^9 and b=s^10, so the factorization is ...

  [tex]r^{27}-s^{30}= (r^9-s^{10})(r^{9\cdot2}+r^9s^{10}+s^{10\cdot2})\\\\=\boxed{(r^9-s^{10})(r^{18}+r^9s^{10}+s^{20})} \qquad\text{matches d}[/tex]

f(x)=x-4 is the answer i believe

Answer :

The function is  

Step-by-step explanation:

Given values in table :

x        f(x)

3         -1

4          0

5          1

6          2

Here we see there is a difference of 4 in the values of x and f(x)

i.e. 3-(-1)=4

or 4-0=4

Similarly 5-1=4

6-2=4

So x-F(x)=4

Adding F(x) -4 both sides

x-F(x) +F(x) -4=4+F(x) -4

We have F(x)= x-4

Answer:

x=30° y=150°

Step-by-step explanation:

The inside angles of a triangle always add up to 180. So 65+85+x=180. x would equal 30. Next a line is always 180 degrees. So to two angles on the line must total to 180 degrees. We know x is 30 degrees, so y is the remaining angle. 30 + y = 180. y is 150.

Answer:

x=30° y=150°

Answer:

-12x+4

Step-by-step explanation:

First, you have to rearrange terms.

-6(-2/3+2x)

-6(2x-2/3)

Now you have to distribute.

-6(2x-2/3)

-12x+4

and that's how you get your answer.

[tex] = \frac{600}{2} [/tex]

= 300 seconds (Ans)

Answer:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

Step-by-step explanation:

Answer:

Slope = 4/3x; y-intercept = -1

Step-by-step explanation:

y + 1 = 4/3x

You have to write this equation in slope-intercept form (solve for y) if you want to find the slope and y-intercept

y + 1 = 4/3x

Subtract one from both sides

y + 1 - 1 = 4/3x - 1

y = 4/3x - 1

Now that we have the equation, you can now find the slope and y-intercept

y = mx + b; m is the slope and b is the y-intercept

So for y = 4/3x - 1, the slope is 4/3x and the y-intercept is -1
