Dilation of 1.5
Step-by-step explanation:
The way I do these equations is pick one coordinate axis and work with that. So for point K, it goes from X & Y coordinate 1 to 1.5, Point I goes from Y coordinate 2 to 3, and Point J goes from y coordinate 2 to 3 again.

Length of the parking lot: Im
(b) The perimeter of a rectangular pool is 352 m.
If the length of the pool is 97 m, what is its width?
width of the pool: Im
Answers
Answer:
A) Length = 94 m
B) Width = 79 m
Step-by-step explanation:
A)
The area of a parking lot is 7802 m²
Area = length x width
7802 = length x 83
length = 7802 ÷ 83
length = 94 m
b)
The perimeter of a pool is 353 m
Perimeter = 2(length + width)
352 = 2(97 + width)
352 = 194 + 2width
2width = 352 - 194
2width = 158
width = 158/2
width = 79 m

Consider the following data set:
2 , − 3 , − 3 , 1 , 8 , 12 , 14 , 2
Find the lower quartile.
Answers
Answer:
-3, -3, 1, 2, | 2, 8, 12, 14
Lower quartile is negative 1
Because the middle number is the median because there is an odd set of numbers.
To find the quartile you have to arrange the numbers from lowest to highest.
When you find middle number you have to find the half of the lower half of the middle, which you will solve the lower quartile. Since there are even numbers you add the two middle numbers and divide it by 2. And you'll get the answer hope that helped
David is making rice for his guests based on a recipe that requires rice, water, and a special blend of spice, where the rice-to-spice ratio is 15:1. He currently has 40 grams of the spice blend, and he can go buy more if necessary. He wants to make 10 servings, where each serving has 75 grams of rice. Overall, David spends 4.50 dollars on rice.
What is the price of rice per gram?
Answers
Answer:
The price of rice per gram is 0.006$
Step-by-step explanation:
I. David wants to make 10 servings,
each require 75 g of rice and 5 spice. When ratio is 15:1
If rice : spice = 75 : x
15x = 75
x = 5
=> 5 * 15 : 1 * 5
= 75 : 5
So rice : spice is 75 : 5
II. When 1 serving require 75 : 5
So 10 servings is 10 * 75 : 5 * 10
= 750 : 50
So he must has 750 grams rice and 50 grams spice.
III. He must buy spice and rice which..
a) He has 40 grams spice, he'll buy for 10 grams spice.
b) He has no rice, he'll buy for 750 grams rice.
But the question only ask for price of rice which he spend 4.5$
= [tex]\frac{4.5}{750}[/tex]
= 0.006$
In 1 gram of rice he spend 0.006$
If 750 grams of rice, he'll spend 750 * 0.006$ = 4.5$ => true
That makes 0.006$ is the right answer.

The sum of three consecutive even integers is 642. What are the integers? (Show your work too please)
Answers
Answer:
212,214,216
Step-by-step explanation:
n+n+2+n+4=642
add the n's and 2 and 4
3n+6=642
subtract 6 from both sides
636 divided by 3
you get 212 then add 2 twice.
Answer:
212, 214, 216
Step-by-step explanation:
Basically you can divide 642 by 3 to find the average number of the 3. get You get 214, so that means 214 + 214 + 214 = 642
We need consecutive EVEN integers though, so you can take the one even BEFORE and then one even AFTER 214
This means 212 and 216 are used as they are 2 before and 2 after, so when added they still total 642.

Find the equation (in terms of x) of the line through the points (-2,4) and (2,0)
y =
Answers
Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 4 ) and (x₂, y₂ ) = (2, 0 )
m = [tex]\frac{0-4}{2-(-2)}[/tex] = [tex]\frac{-4}{2+2}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1 , then
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 0 )
0 = - 2 + c ⇒ c = 0 + 2 = 2
y = - x + 2 ← equation of line

Is this your question?
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour. His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour. (the question is What is Mila's average swimming speed?)
Answer:
Mila's average swimming speed is 34.44 m/min.
Logan's average speed is 2.25 kilometers per hour.
Step-by-step explanation:
Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's
To Find:
What is Logan's average swimming Speed?
Solution:
The relationship between speed, distance, and time is easily remembered when you consider that speed is written in terms of units of distance per units of time. (miles per hour, or kilometers per hour, for example) "per" means "divided by".
[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]
[tex]\left[speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h\right][/tex]
Logan's average speed is 2.25 kilometers per hour.
-------------------------------------------------------------------------------------------------------------
Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour
To find:
What is Mila's average swimming speed?
Solution:
The distance swam by Logan = 750 m
The distance swam by Mila = 2/3 of Logan's distance = 2/3 x 750 = 2 x 250 = 500
The time taken by Mila to swim 500 m = 1/4 of an hour = 1/4 x 60 = 15 Minutes [since 1 hr = 60 mins]
We know the formula as:
[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]
Now, substituting the values in the formula above to find the speed of swimming of Mila,
The average swimming speed of Mila = [tex]\frac{500m}{15mintues}[/tex][tex]=33.34m/min[/tex]
Therefore, Mila's average swimming speed is → 34.44 m/min.
