Answer:

sum of angles in atriangle=180°

Step-by-step explanation:

w-45°+w-37°+w+19°=180°(sum of angles in a triangle)

3w=180°+45°+37°-19°

3w=243°

w=81°

Answer:

not sure

Step-by-step explanation:

Following are the calculation to the given coordinates:

[tex]\to T (-2, 5)[/tex]

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

Also, as a result, the coordinates of point T' after the Ry-axis are as follows: (2, 5).

[tex]\to[/tex] (-2, 5) is the image (-2, -5).

Answer:

The graph shown has a slope of -4 (the line goes up 4 units for every 1 unit traveled to the left)

The y-intercept (where the line crosses the y axis) is -3

Slope-intercept form is y=mx+b

(m=slope)

(b= y-intercept)

Therefore, your answer would be y=-4x-3

Answer:

1680 vehicles

Step-by-step explanation:

28 per minute

60 minutes in an hour

28 * 60 = 1680

Answer:

1,680

Step-by-step explanation: 28x60=1,680

Answer:

20

Step-by-step explanation:

step 1: Evaluate the expressions

6*10^7 = 60,000,000

3*10^6 =  3,000,000

step 2: Devide

60,000,000 / 3,000,000 = 20

so 60,000,000 is 20 times larger than 3,000,000

Your teacher might want you to use a different method, but I believe this is the simplest way. If you have any questions feel free to ask away

Answer:

20

Step-by-step explanation:

[tex] \dfrac{6 \times 10^7}{3 \times 10^6} = \dfrac{6}{3} \times 10^{7 - 6} = 2 \times 10^1 = 20 [/tex]
