Answer 1

Problem 9

List any three points that are on the same straight line.

So for example, you could say A, P and B. Or you could say C, P, and D. A third one you could do is J, D and K.

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

Problem 10

Now we're listing any three points that aren't on the same straight line.

One example of such triple is A, P and D. Another example is K, D, and C. There are many others as well.

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

Problem 11

List any four points that are in the same plane. So you'll pick four points from the set {A, B, C, D, P} to answer this question as these five points are all in the shaded plane R.

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

Problem 12

Pick any four points such that they do not all exist in the same plane. It doesn't matter which points you pick as long as J or K are one of the points selected. This is because neither J nor K are in the plane R.

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

Problem 13

Line JK intersects CD at point D. The other line that crosses CD is line AB.

Line AB is in plane R, while line JK intersects the plane at point D only.

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

Problem 14

Intersecting line JK and plane R results in point D. This is where the line and plane meet, as mentioned in the previous problem.

If you were asked to intersect line AB and plane R, then you would get line AB as a result. All of line AB is inside the plane.

centimeters. Write it in three forms.

I need help please someone let me know!!

Answers

Answer:

[tex]1\,\,m^3\,=\,10^6\,\,cm^3[/tex]

Step-by-step explanation:

To find: conversion factor between cubic meters and cubic centimeters

Solution:

One meter is 100 times greater than one centimeter .

1 meter = 100 centimeter

That is [tex]1\,\,m\,=\,100\,\,cm[/tex]

So,

The Schmidts brought a house 10 years ago and took out a mortgage. They are considering selling and want to know how much they still owe. They know their monthly payment and interest rate. Which of the following methods and correctly allow them to find the amount still owed?

Answers

Answer: a. They can find the present value of the remaining 20 years worth of payments.

Step-by-step explanation:

The present value of the payments for the servicing of the loan is the amount of the loan that is still owed because the payments include both the interest and the principal repayments.

The Schmidts can therefore find out the amount they still owe by checking the present value of the remaining 20 years worth of payments.

As the payments are usually constant they can be treated as an annuity so using the monthly payment as the annuity, the interest rate as the discount rate and the 20 years ( 240 months) as the period, they should be able to find the present value of the loan.

Dominic works on the weekends and on vacations from school mowing lawns in his neighborhood. For every lawn he mows, he charges $12. Complete the table. Then determine ordered pairs, and create a labeled graph. 1. How many lawns will Dominic need to mow in order to make $240? _________(blank 1) 2. How much money will he make if he mows 9 lawns? _________(blank 2) Question 1 options: Blank # 1 Blank # 2

Answers

Answer:

[tex]20\ lawns = \$240[/tex]

[tex]9 \ lawns = \$108[/tex]

See Attachment for Graph

Step-by-step explanation:

Given

[tex]1\ lawn = \$12[/tex]

Solving (a): Number of lawns in $240

[tex]1\ lawn = \$12[/tex]

Multiply both sides by 20

[tex]20 * 1\ lawn = \$12 * 20[/tex]

[tex]20\ lawns = \$240[/tex]

Solving (b): Cost of mowing 9 lawns

[tex]1\ lawn = \$12[/tex]

Multiply both sides by 9

[tex]9 * 1\ lawn = \$12 * 9[/tex]

[tex]9 \ lawns = \$108[/tex]

To create a graph, we need to generate a formula;

[tex]1\ lawn = \$12[/tex]

[tex]2\ lawn = \$24[/tex]

[tex]3\ lawns = \$36[/tex]

[tex]x\ lawns = \$12x[/tex]

So:

The graph formula is

[tex]y = 12x[/tex]

Evaluate 32 + (8 − 2) ⋅ 4 − 6 over 3 . (1 point

Answers

Answer:

The answer would be 54 because you would follow the order of PEMDAS

you would do parentheses first which is 8-2 which is 6 then multiplication

so 6x4 = 24 then addition which is 32+24 which equals 56, then you would do 56-6/3 which would equal 54

For the directed line segment whose endpoints are B(0, 0) and C(12, 24), find the point whose coordinates are 3/4 from B to C.

Answers

Answer:

(9, 18)

Step-by-step explanation:

If point P is 3/4 of the distance from B to C, it means that ...

BP/BC = 3/4

(P - B) = 3/4(C - B) . . . . . . multiply by BC = (C-B)

P = B + 3/4C -3/4B . . . . . add B

P = (1/4)B +(3/4)C = (B +3C)/4

P = ((0, 0) +3(12, 24))/4 = (36, 72)/4 = (9, 18)

The desired point is (9, 18).

As we showed, since B = (0, 0), the point is 3/4 of the coordinates of C.

In 2016 49% of all degrees granted were bachelors degrees if 1,920,718 students earned bachelors degrees how many total degrees were granted that year

Answers

Answer:

3919832.65306

Step-by-step explanation:

This problem is focused on percentages.

Now given that 49% of a number is 1,920,718

we can say let the number be x

so 49% of x= 1,920,718

now expressing this problem mathematically we have

(49/100)*x= 1,920,718

0.49x= 1,920,718

divide both sides by 0.49 we have

x= 1,920,718/0.49

x= 3919832.65306

Therefore the total that were granted degree that year was 3919832.65306

Find the coordinates of the midpoint of AS if A(-4, 7) and S(5,3).

Answers

Answer:

The answer is

[tex]( \frac{1}{2} \: , \: 5)[/tex]

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(-4, 7) and S(5,3)

The midpoint is

[tex]M = ( \frac{ - 4 + 5}{2} , \: \frac{7 + 3}{2} ) \\ = ( \frac{1}{2} , \: \frac{10}{2} )[/tex]

We have the final answer as

[tex]( \frac{1}{2} \: , \: 5)[/tex]

Which system of inequalities is represented by the graph?
A. y≥1
y−x>0
B. y≤1
y−x 0
2. Which system of inequalities is represented by the graph?

Answers

Answer:

B, D

Step-by-step explanation:

1. The shaded area is below the solid line at y=1, so the solution set is partially determined by the inequality ...

y ≤ 1 . . . . . . values of y in the solution set are less than or equal to 1

The shaded area is below the line y=x, so is partially determined by ...

y -x < 0

These inequalities match the second choice.

2. The solid boundary line has a slope, rise/run, of 1/3. The shaded area is below it. So the applicable inequality is ...

y ≤ 1/3x +6 . . . . . . matches the fourth choice

The length of a rectangle is 3 units greater than its width. If the width is w, what expression gives the perimeter of the rectangle in terms of its width?

Answers

Step-by-step explanation:

let width be "w"

given,length of rectangle is 3 units greater than its width

length= w+ 3

perimeter of rectangle= 2( l+ b)

= 2[( w+3)+ w]

= 2(w to the power of 2 + 3w)

= 2w to the power of 2 + 6w

is the answer

The perimeter of the rectangle is 4w+6 units

What is the perimeter of rectangle?

The perimeter of a rectangle is the sum of its four sides. Perimeter of Rectangle = 2 (Length + Width) units.

According to the question

Width of rectangle = w

Length of rectangle = w+3

Perimeter of Rectangle = 2 (Length + Width)

= 2( w+3 +w)

= 2(2w+3)

= 4w+6 units

Hence, The perimeter of the rectangle is 4w+6 units .

The distance between the endpoints of line segment XY will be 15.2 units.

What is the distance between two points?

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x - h)² + (y - k)²

The endpoints of line segment XY are given below.

X(-9, 2) and Y(5, -4)

The distance between the endpoints of line segment XY will be given as,

D² = (x - h)² + (y - k)²

D² = (5 + 9)² + (-4 - 2)²

D² = (14)² + (-6)²

D² = 196 + 36

D² = 232

D = √232

D = 15.2 units

The distance between the endpoints of line section XY will be 15.2 units.
