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
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;
If
[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]

Find a conversion factor between cubic meters and cubic
centimeters. Write it in three forms.
I need help please someone let me know!!
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,
[tex]1\,m^3\,=\,1000000\,cm^3[/tex]
or
[tex]1\,m^3\,=10^6\,cm^3[/tex]
or
[tex]1\,cm^3\,=\,\frac{1}{10^6}\,m^3[/tex]

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.
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.
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?
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 .

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
Answer:
3919832.65306Step-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

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?
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
Put these numbers in order from least to greatest.

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?
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.

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.
