Answer:

x=25°, y=18°

Step-by-step explanation:

Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!

Answers

Answer:

W = 9 inches.

Step-by-step explanation:

The volume of a rectangular prism is given by

[tex]V=whl[/tex]

Where

w,h and l re width, height and length of rectangular prism

It is not mentioned that a box has a length of 18 inches and a height of 3 inches.

Using above formula.

if each side of the cube shown above has the same length as the measured side what is the approximate volume of the cube

Answers

Answer:

The measured side is not shown, so i will answer in a general way.

A cube is a 3-dimensional object with 6 square faces.

You know that all the sides of a square have the same length, then is the same for the cube.

To calculate the volume of a cube, we start with the area of the base.

The base is a square of sidelength L (Suppose that L is the length of the measured side)

The area of the base is:

A = L^2.

To find the volume, we must multiply the area of the base by the height of the fire (because the section of the base does not change).

And the height of the cube is also L.

Then the volume is:

V = L*a = L^3

Two groups of hikers take two different routes from Camp A to Camp B. The first group leaves Camp A at 9:00 AM and takes a route that is 30 miles longer than the second group's route. The second group leaves Camp A at 1:00 PM. Their hiking speed is 2 mph slower than the first group's speed. Both groups reach Camp B at 4:00 PM. How fast does each group hike?

Answers

Answer: first groups hiking was 6mph, second groups was 4mph.

Step-by-step explanation:

Speed of first group = 6 mph

Speed of second group = 4 mph

We are told that first group leaves Camp A at 9:00 AM.

If the normal distance between camp A and camp B is x, then the total distance this first group covers will be;

(x + 30) miles

This first group reached camp B at 4pm. This is 7 hours from when they left camp A.

Thus, their speed is;

v1 = (x + 30)/7 mph

We are told that;

Second group left by 1pm and got to camp B by 4pm. This is 3 hours.

We are also told that their speed was 2mph slower than the first group.

Thus;

v2 = ((x + 30)/7) - 2 mph

Since normal distance from camp A to camp B is x. Then this second group will have;

x = ((x + 30)/7) - 2) × 3

Since;

distance = speed × time

Divide both sides by 3 to get;

x/3 = ((x + 30)/7) - 2)

Multiply through by 21 to get;

7x = 3(x + 30) - 42

7x = 3x + 90 - 42

7x - 3x = 48

4x = 48

x = 48/4

x = 12 miles

Thus, putting 12 for x in V1 equation gives;

v1 = (12 + 30)/7

v1 = 42/7

v1 = 6 mph

Similarly;

v2 = ((12 + 30)/7) - 2

v2 = (42/7) - 2

v2 = 6 - 2

v2 = 4 mph

Nola hiked down a trail at a steady rate for 10 minutes. Her change in elevation was −190 feet. Then she continued to hike down for another 20 minutes at a different rate. Her change in elevation for this part of the hike was −200 feet. During which portion of the hike was her rate of change in elevation greater? Complete the explanation. Her rate was faster in the (Select: First, Second) part of the hike, because her heart rate was ____ ft/min in the first part and ___ ft/min in the second part.

Answers

Answer:

Her rate was faster in the FIRST because her rate was - 19 ft/ minutes in the FIRST PART and - 10ft/minute in the SECOND part

Step-by-step explanation:

Portion 1

Time taken to hike down = 10 minutes

Change in elevation = - 190 ft

Portion 2

Hiked down for further 20 minutes

Change in elevation = - 200ft

During which portion of the hike was her rate of change in elevation greater?

Rate of change in elevation :

Change in elevation / time

Portion 1:

Rate of change in elevation :

Change in elevation / time

- 190 ft / 10 minutes = - 19 ft/minutes

Portion 2:

Rate of change in elevation :

Change in elevation / time

- 200 ft / 20 minutes = - 10 ft/minutes

Her rate was faster in the FIRST because her rate was 19 ft/ minutes in the FIRST PART and 10ft/minute in the SECOND part

What is the equation olf the line that is parallel to the gven line and has an x-intercept of 3? Oy-x+3 Oy-x+2 Oy=-x+3 Oy=-x+2​

Answers

Answer:

It’s D

Step-by-step explanation:

The equation of the parallel line is y = x - 3, the correct option is C.

What is y-intercept of a function?

The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

We are given that;

x-intercept = 3

Now,

we can find the equation of the line parallel to the given line and passing through the point (3, 0):

The given line has an equation of y = x + 3. This is already in slope-intercept form, so we can see that the slope is 1. The parallel line will have the same slope of 1.

The point that the parallel line passes through is (3, 0). We can use this point and the slope to write the equation of the parallel line in point-slope form:

y - 0 = 1(x - 3)

y = x - 3

Therefore, the slope intercept will be y=x-3
