Answer 2

Answer:

The vertices of image are (5,1), (2,-5) and (-4,-5).

Step-by-step explanation:

The vertices of triangle are (5,-1), (3,-5) and (-1,-5).

If a figure dilated by scale factor k centered at (a,b), then

[tex](x,y)\rightarrow (k(x-a)+a,k(y-b)+b)[/tex]

The figure after a dilation with a scale factor of 3/2 centered at (5, −5).

[tex](x,y)\rightarrow (\frac{3}{2}(x-5)+5,\frac{3}{2}(y+5)-5)[/tex]

The coordinates of image are

[tex](5,-1)\rightarrow (\frac{3}{2}(5-5)+5,\frac{3}{2}(-1+5)-5)\rightarrow (5,1)[/tex]

[tex](3,-5)\rightarrow (\frac{3}{2}(3-5)+3,\frac{3}{2}(-5+5)-5)\rightarrow (2,-5)[/tex]

[tex](-1,-5)\rightarrow (\frac{3}{2}(-1-5)+5,\frac{3}{2}(-5+5)-5)\rightarrow (-4,-5)[/tex]

Therefore vertices of image are (5,1), (2,-5) and (-4,-5).

Consider the two functions shown here. Which function has the greater rate of change? Explain your answer.
A) Function 1, because the rate of change is 2.
B) Function 2, because the rate of change is ½.
C) Function 2, because the rate of change is 7.
D) Function 1, because the rate of change is ½ .

Answers

rate of change = slope

function 1 :
(0,0)(1,2)
slope = (2 - 0) /(1 - 0) = 2/1 = 2

function 2 : y = 1/2x + 7...in y = mx + b form, the slope is in the m position.
so ur slope here is 1/2.

so function 1 has a greater rate of change because it is 2.......function 2 has 1/2 rate of change

Answer: The answer is A- Function 1, because its rate of change is 2.

Mr. Chin's hotel bill is $143. He leaves 12% of the hotel bill as a tip for the housekeeping service. What is the total amount Mr. Chin pays, including tip? $160.16 $165.00 $170.50 $174.46

Answers

First, begin by converting the tip of 12% to a decimal.

.12

Now, multiply that by the total bill.

.12*143=17.16

We now know the numerical value of the tip.

Add the tip to the total bill and get your answer.

143+17.16=160.16

Danika and Karen bought a pizza that was cut into 8 slices. If Danika ate 3/4 of the pizza, how many slices were left for Karen?

Answers

2 slices left for karen
Since 4/4 is 8, to solve for 1/4, you have to divide 8 by 4, which is 2. 1/4 = 2, so 2/4 = 4, and 3/4 = 6. Danika ate 6 slices of pizza because she ate 3/4 of the pizza. Since there is only 1/4 left, Karen only has 2 slices of pizza left. Another way you could do it is you could subtract 6 from 8 to get the remaining amount, and you would still get 2 slices left for Karen.

A 20,000 gallon swimming pool contains 5000 gallons of water when a hose is placed into the pool and begins adding water at a rate of 1250 gallons per hour. Use the Segment tool to plot a graph representing the volume of water in the pool over time from when the hose is placed into the pool until it is full.

Answers

20000-5000=15000

15000/1250=12

it will take 12 hours

Solution: The  figure 1 shows the graph of the volume of water in the pool over the time from when the hose is placed into the pool until it is full.

Explanation:

It is given that the capacity of the pool is 20,000 gallon and initial water in the pool is 5000 gallons. The remaining capacity of the pool is 15,000 gallons.

The water in the pool increased at the rate of 1250 gallons per hour.

[tex]\frac{15000}{1250}=12[/tex]

So tank will be full after 12 hours.

The initial water in the pool is 5000 gallons and water in the pool increased at the rate of 1250 gallons per hour. So, the volume of water in the pool is described by the equation [tex]V=5000+1250t[/tex].

First we find the value of volume function in different value of t, then plot these points in a coordinate plane and join them with a straight line.

Hence, the coordinate table and graph of the volume function is given below.

Charlie runs at a speed of 3 yards per second. About how many miles per hour does Charlie run

Answers

To find the answer, you first must find how many yards Charlie can run in a minute. Since there are 60 seconds in a minute, you multiply 3 times 60, which is 180. Then you must multiply this number by 60 again, because there are 60 minutes in an hour. This equals 10,800, your answer.


Charlie can run 10,800 yards in an hour.
The answer is 6.1 miles

The function w(x) = 60x represents the number of words w(x) you can type in x minutes, how many words can you type in 9 minutes

Answers

To solve this, plug in your given x value (9 minutes) in for x in your formula, so w(x)=60(9)=540 words as your answer.

Answer:540 words

Step-by-step explanation:

Given : The function [tex]w(x) = 60x[/tex] represents the number of words w(x) you can type in x minutes.

Then to find the number of words typed in 9 minutes , we need to pit x= 9 in the function .

The  number of words can be typed in 9 minutes :  [tex]w(9) = 60(9)=540[/tex]

Hence, we can type 540 words in 9 minutes .

Marc is running 5 kilometers at track practice. He decides to break the run into 3 equal lengths. How long will each length be?

Answers

Divide 5 by 3.
If you do this on a calculator you will get 1.666666667.
You will then round that to 1.7
Because "4 or less let it rest, 5 or more raise the score"

Each length of the track practice will be 1.67 kilometers.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Marc is running 5 kilometers at track practice.

And, He decide to break the run into 3 equal lengths.

Now,

Since, Marc is running 5 kilometers at track practice.

And, He decide to break the run into 3 equal lengths

So, The length of each track practice = 5 / 3

                                                          = 1.67 kilometer

Thus, Each length of the track practice will be 1.67 kilometers.

Answers

The answer is The total area of the top and bottom squares. s = √7 cm is irrational value and we need rational value. Let's check all choices: A. The volume. V = (s)^3. If s = √7, V = (√7)^3 = 7√7 - irrational value. B. The perimeter of the front square. P = 4 * s = 4 * √7 = 4√7 - irrational value. C. The diagonal of the back square. d = s√2 = √7 * √2 = √(7*2) = √14 - irrational value. D. The total area of the top and bottom squares. A = 2 * s^2 = 2 * (√7)^2 = 2 * 7 = 14 - rational value.

a manager purchased a total of 21 coffee mugs and key chains. each coffee mug cost $8.50, and each key chain cost $2.75 . if manager spent total of $132.50, how many coffee mugs did the manager purchase

Answers

Final answer:

The manager purchased 13 coffee mugs.

Explanation:

To find the number of coffee mugs purchased, we can set up a system of equations. Let's say the number of coffee mugs is represented by x and the number of key chains is represented by y. We have two pieces of information:

1. The total number of items purchased is 21: x + y = 21

2. The total cost of the purchase is $132.50: 8.50x + 2.75y = 132.50

Now we can solve this system of equations to find the value of x, which represents the number of coffee mugs:

Multiplying the first equation by 8.50, we get: 8.50x + 8.50y = 178.50

Subtracting the second equation from this new equation, we get: 8.50x + 8.50y - 8.50x - 2.75y = 178.50 - 132.50

Simplifying, we have: 5.75y = 46

Dividing both sides of the equation by 5.75, we find: y = 8

Substituting this value into the first equation, we can solve for x: x + 8 = 21

x = 13

Therefore, the manager purchased 13 coffee mugs.
