Answer: "reduced by a factor of One-third."
Step-by-step explanation:
Suppose that the original magazine has a length L and a width W.
If it is photocopied using a scale factor of K, then the measures of the photocopy will be:
length = K*L
Width = K*W
In this case, the scale factor is K = 1/3, then the measures of the photocopy will be:
length = (1/3)*L = L/3
Width = (1/3)*W = W/3
For usual notation:
When k > 1, we have an enlargement by a factor k
when 0 < k < 1, we have a reduction by a factor k
in this case, k = 1/3, then:
We have a reduction by a factor of 1/3
The correct option is:
"reduced by a factor of One-third."
Answer: D-reduced by a factor 1/3

Timothy purchased a computer for $1000. The value of the computer depreciates by 20% every year.
Answer:
We can apply the straight-line method to solve for the value of the computer every year.
Step-by-step explanation:
Step one:
What is depreciation?
It can be defined as the loss of value of a commodity.
In this problem, the percent depreciation is given as 20% which means that 20% of the worth of the computer is lost every year.
We are told that the computer cost is $1000
let the number of years taken for the computer to depreciate be x
Step two:
Say we want to find the value of the computer after 1 year, the value of the computer will be
Value of computer= 1000-20/100*1000
Value of computer= 1000-0.2*1000
Value of computer= 1000-200
Value of computer= $800
Step three:
For the second year, the value will be
Value of computer= 800-20/100*800
Value of computer= 800-0.2*800
Value of computer= 800-160
Value of computer= $640
Answer:
This situation represents exponential decay. The rate of growth or decay, r, is equal to 0.2. So the value of the computer each year is 80% of the value in the previous year. It will take 3 years for the value of the computer to reach $512.

Write the word sentence as an inequality. Then solve the inequality.
The product of −2 and a number x is greater than 30.
An inequality is
.
The solution of this inequality is
.
Answer:
-2(x)>30
An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
x<-15
Step-by-step explanation:
-2(x)>30 means to divide -2 on both sides which is -15.
x>-15
Next you switch the inequality because you multiplied by a negative:
x<-15
If the diagonal of a television screen is 24 inches and the width is 16 inches,
what is the height of the screen? Leave the answer in simplified radical form
Please show you're work
Step-by-step explanation:
Let x be the height of the screen.
Using Pythagoras' Theorem,
we have x² + 16² = 24².
Therefore x² = 24² - 16² = 320,
x = √320 = 8√5 in.
The height of the screen is 8√5 inches.
6. What is the solution to the equation 2/3x + 1 = 1/6x - 7? *
X = -16
x = -4

A landscaper wants to create a rectangular patio in a backyard. He wants it to have a total area of 148 square feet and it should be 8 feet longer than it is wide. What dimensions should he use for the patio? Round to the nearest tenth of a foot if necessary
Answer:
L=16.8
w = 8.8
Step-by-step explanation:
L = x +8
w = x
x(x+8) = 148
x^2 + 8x = 148
x^2 + 8x - 148 =0
a = 1
b = 8
c = - 148
x = [tex]\frac{-8 +/- \sqrt{8^2 + 4*1*(-148)} }{2}[/tex]
(x - 8.8)(x + 16.8) = 0
(x + 16.8) is an extraneous root.
x = 8.8 which is the width
L = 16.8

$25.08
Step-by-step explanation:

Two apps on your phone take away points for using your phone at school. You have 140 points on the first app and 80 points on the second app when a school day begins. Each time you check your phone, you lose 10 points on your first app and $p$ points on your second app. After you check your phone ten times, you have the same number of points on each app. Find the value of $p$
Answer: p = 4
Step-by-step explanation:
For app one, you start with 140 points, and you lose 10 each time you check your phone.
Then, if you check your phone x times, you will have:
140 - x*10 points in total.
For app two, you start with 80 points, and you lose p points each time you check your phone.
Then, if you check your phone x times, you will have:
80 - x*p points left
We know that when x = 10, you have the same number of points in both apps, then we have the equation:
140 - (10)*10 = 80 - (10)*p
We can solve this for p
140 - 10*10 = 80 - 10*p
140 - 100 = 80 - 10*p
40 = 80 - 10*p
10*p = 80 - 40
10*p = 40
p = 40/10 = 4
Solve for p. p/8 + 12 = 36
9514 1404 393
Answer:
p = 192
Step-by-step explanation:
p/8 +12 = 36 . . . . . given
p/8 = 24 . . . . . . . . .subtract 12
p = 8·24 . . . . . . . . .multiply by 8

Solve for x: x — 10 = 3х – 12
Answer:
x=1
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
x−10−3x=3x−12−3x
−2x−10=−12
Step 2: Add 10 to both sides.
−2x−10+10=−12+10
−2x=−2
Step 3: Divide both sides by -2.
−2x/−2 = −2/−2
x = 1

Joe has eaten 2/5 of a pizza.Jane has eaten 1/6 of a pizza how many more pizza has joe eaten than Jane?
Joe ate 7/30 more of pizza than Jane. You can just subtract 2 uneven denominators. So you would turn them into 30 because that’s the closest highest number that can go with 5 and 6. Then multiply 2 with 6 which is 12 and then multiply 1 with 5 which is 5 now you can subtract it. 12/30-5/30=7/30.
Final Result: 7/30

Answer:
measure of Arc FJ is 80 degrees.
Step-by-step explanation:
Key skills: High School Geometry, One Variable Equations, Angles
1)Let's look at the diagram thoroughly
2) The 2 thing we can get are:
Angle HKG and Angle IKJ are vertical angles (which means they are congruent). Angle HKG + Angle GKF + Angle FKJ = 180 (Since they all form a straight angle - A straight angle is 180 degrees in measure.)3) First we can use the fact that Angle HKG and Angle IKJ are vertical angles. This makes them congruent (Or equal in size)
We can then solve for x by making the equation: 3x-22=x+104) Solve this by moving the x's to one side, and the numbers to the other. You would then get: 3x-x=10+22
3x-x= 2x 10+22=32
2x=32
Divide by 2 on both sides and x=16.
5) We get that x=16. Now to find the measure of Arc FJ, we need to use the fact that Angle HKG + Angle GKF + Angle FKJ = 180
What we want to find is Angle FKJ. The measure of Angle FKJ would be the measure of Arc FJ
6) We can make an equation: x+10+74+Angle FKJ=180
Solve this --> x=16, so substitute it in16 + 10 + 74 + Angle FKJ=180100 + Angle FKJ = 180Angle FKJ = 80 degreesIf Angle FKJ is 80 degrees, then Arc FJ measures 80 degrees.
