Suppose angle A and angle B are supplementary.

The measure of angle A is (15x + 65) and the measure of angle B is (50x - 15).

Solve for x (showing your setup and work) and then find the measure of angle A and the measure of angle B

Answers

Answer:

x = 2

Angle A = 95°

Angle B = 85°

Step-by-step explanation:

Concepts

Supplementary angles are angles that sum up to 180° to form a straight angle.

Application

We are asked to find the value of x, Angle A, and Angle B. We are given angles A and B as 15x + 65 and 50x - 15. To do this, we can set up the equation 15x + 65 + 50x - 15 = 180 because we know these angles are supplementary, or adding to 180°. Then, once we get the value of x, we plug in that value for each angle.

Solution

Step 1: Simplify both sides.

[tex](15x+50x) +(65-15)=180[/tex] [tex]65x+50=180[/tex]

Step 2: Subtract 50 from both sides.

[tex]65x+50-50=180-50[/tex] [tex]65x=130[/tex]

Step 3: Divide both sides by 65.

[tex]65x/65 = 130/65[/tex] [tex]x=2[/tex]

Step 4: Plug x into angle A.

[tex]15(2)+65 = 30 + 65 = 95[/tex]

Step 5: Plug x into angle B.

[tex]50(2) - 15 = 100 - 15 = 85[/tex]

if [tex]v=v_{1} +v_{2}[/tex], where [tex]v_{1}[/tex] and [tex]v_{2}[/tex] are not both 0 and [tex]u=-3v[/tex], find the measure of the angle between [tex]u[/tex] and [tex]v[/tex].
Given:
[tex]\frac{u*v}{||u|| ||v||}[/tex]

Answers

If θ is the angle between u and v, then

u • v = ||u|| ||v|| cos(θ)

Since u = -3v, we have

u • v = (-3v) • v = -3 ||v||²

and

||u|| = ||-3v|| = 3 ||v||

If v₁ and v₂ are both not zero, then ||v| ≠ 0.

Then

cos(θ) = (-3 ||v||²) / (3 ||v|| ||v||) = 1

which means θ = π rad = 180°.

The distance from the school to the grocery store is

Answers

The distance between the school and the grocery store is 3,000ft.

What is the distance from the school to the grocery store?

First, we need to find the distance between the two locations, we know that:

School is at (4, 5)Grocery store is at (4, -1)

The distance between these two points is:

[tex]d = \sqrt{(4 - 4)^2 + (5 - 1)^2} = 4[/tex]

And we know that each unit represents 750ft, then we can see that the total distance is:

d = 4*750ft = 3,000ft

And the graph of the 4 points can be seen below.

His home is at the originThe school is at (4,5)The zoo is at (-3,2).The park is at (-4,-4).The grocery store is at (4.-1)

From the image attached below, there are 6 unit differences showing the distance from the school to the grocery store. If each unit in the coordinate plane represents 750 feet.

there are 1800 pupils in a school of witch 2/5 are girls. 540 of the pupils do not play sports. Of these pupils who do not play sports, 5/9 are girls. How many boys play sports?

Answers

Answer:  840

========================================================

Explanation:

There are 1800 students total.

Take 2/5 of this to find the number of girls

(2/5)*1800 = 720 students are girls

Subtract that result from the total to get the number of boys

1800-720 = 1080 students are boys

We'll use this value later, so let A = 1080.

-------------

540 students do not play sports

(5/9)*540 = 300 girls do not play sports.

540-300 = 240 boys do not play sports

Let B = 240

------------

We found that

A = 1080 boys totalB = 240 boys do not play sports

Therefore,

A-B = 1080 - 240 = 840 boys play sports

Which statements describe the figure on the grid if each square has side lengths of 1 cm? Check all that apply. On a coordinate plane, a figure covers 12 full squares and 12 partial squares. The bottom of the figure is diagonal and crosses 6 squares. The perimeter of the figure is 18 cm. The length of the top of the figure is less than 6 cm. The area of the figure is the sum of 12 full squares and 12 partial squares. The area of the figure is greater than 24 square centimeters. The length of the bottom of the figure is greater than 6 cm.

Answers

The figure on the grid is an illustration of areas and perimeters of a shape

How to determine the true statements?

The question is incomplete, as the figure is not given.

So, I will provide a general explanation on how to determine the area and the perimeter of a shape.

The area of a shape is the amount of space on that shape.

Take for instance a square that has a side length 5 units.

The area of the square would be:

Area = 5 * 5 = 25 square units

On the other hand, the perimeter is the sum of the side lengths of the shape.

Using the same square that has a side length 5 units.

The perimeter of the square would be:

Perimeter = 4 * 5 = 20 units

Suppose that 2 ≤ f '(x) ≤ 4 for all values of x. What are the minimum and maximum possible values of
f(5) − f(1)?

Answers

Answer:

Step-by-step explanation:

By the Mean Value Theorem, there is at least one number, c, in the interval (1,6) such that

f'(c) = [f(6) - f(1)]/ (6 - 1)

So, f(6) - f(1) = 5f'(c).

Since 2 ≤ f'(c) ≤ 4, 10 ≤ 5f'(c) ≤ 20

So, f(6) - f(1) is between 10 and 20.
