8 hours, the car caught up. What was the train's average speed?

Answers

Answer 1

Answer:

45.538 mph

Step-by-step explanation:

v = d/t (velocity = distance/time)

74 mph = d/8

d = 592 miles

[tex]v_{train}=\frac{592 miles}{5+8 hours}[/tex]

= 45.538 mph

The value of angle x will be 91° for the given triangle.

What is a triangle?

A triangle is a polygon with three sides, three vertices (corners), and three angles. The sum of the three angles in a triangle is always 180 degrees. Triangles are important in geometry and mathematics, and they have many applications in science, engineering, and everyday life.

Triangles can also be used to calculate the areas of various two-dimensional shapes and to solve problems related to distance, angles, and proportions.

Triangle fixed value = 180

x = 180 - (45 + 44)

x = 180 - 89

x = 91

Therefore, the value of x is 91°

1. Write the slope-intercept form of the equation that passes through the point (0, 1) and is parallel to the line y = 3x - 5
O y = 3x + 1
O y = 3x - 4
O y = -1/3x - 4
O y = -1/3x + 1

Answers

Answer:

y = 3x + 1

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope.

The first line is Y = 3X - 5. Its slope is 3. A line parallel to this one will also have a slope of 3.

Plug this value (3) into your standard point-slope equation of y = mx + b.

y = 3x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (0, 1). Plug in the x and y values into the x and y of the standard equation.

1 = 3(0) + b

To find b, multiply the slope and the input of x (0)

1 = 0 + b

Now, add 0 to both sides to isolate b.

1 = b

Plug this into your standard equation.

y = 3x + 1

This equation is parallel to your given equation (y = 3x - 5) and contains point (0, 1)

ΔAXY ~ ΔABC. What is the value of BC

Answers

Answer:

BC = 28 [tex]\frac{1}{3}[/tex] ft

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AX}{AB}[/tex] = [tex]\frac{XY}{BC}[/tex] , substitute values

[tex]\frac{12}{20}[/tex] = [tex]\frac{17}{BC}[/tex] ( cross- multiply )

12BC = 340 ( divide both sides by 12 )

BC = [tex]\frac{340}{12}[/tex] = [tex]\frac{85}{3}[/tex] = 28 [tex]\frac{1}{3}[/tex]

x = 30

Step-by-step explanation:

multiply the fraction by 4 and the 8 by 4 because what you do to one side you have to do to the other. The 4 times the /4 cross out because you can't do math there. Now your left with x+2=32 because 4 times 8 equals 32. But you still have to keep going because we need x all alone. Now you subtract 2 form 2 and 32 from 2. The 2's cancel out and 32 minus 2 equals 30. x = 30

Plz hurryThe center of circle Q has coordinates Q(6,-4) . If circle Q passes through R(14,2) , what is the length of its diameter?

Answers

Answer:

the diameter is twice the circle radius, or 20

Step-by-step explanation:

Recall that the radius is half the diameter <=> the diameter is twice the radius.  In this problem we need to find the radius first, then multiply it by 2 to obtain the diameter.

We need to determine the distance between the center of the circle Q(6, -4) and the point R(14, 2) on the circle.  

The Pythagorean Theorem applies here.  Going from Q to R, x changes from 6 to 14, or 8 units, which is the horizontal leg of a right triangle, and y changes from -4 to 2, or 6 units.  Thus, according to the Pythagorean Theorem, the length of the hypotenuse of this triangle is

r = √(6² + 8²) = √100 = 10

and so the diameter is twice that, or 20.

3x – 2y = -2
3x + y = 10

Answers

Answer:

x = 2 ; y= 4

Step-by-step explanation:

3x -2y = -2

y = -3x+10

3x + 6x -20 = -2

9x = 18

x = 2

y = -6 + 10

y = 4

Answer:

x = 2

y = 4

Steps:

given:

3x – 2y = -2

3x + y = 10

2y = 3x+2

y = (3x+2)/2

3x + y = 10

3x + (3x+2)/2 = 10

(6x+3x+2)/2 = 10

(9x + 2)/2 = 10

9x + 2 = 20

9x = 18

x = 2

y = 4
