Step-by-step explanation:
The question asks you to dilate the rectangle by a scale factor of 1/3.
KEY TERM:
Dilate by a scale factor: You make a shape bigger or smaller by multiplying by a number.
Here, we are dilating by a scale factor of 1/3. Therefore, to solve the problem, you have to multiply each coordinate by 1/3. Also, we are making the shape smaller because we are multiplying by a fraction.
___
STEP 1: LINE UP ALL THE COORDINATE PAIRS
Point U: (-6,6)
Point R: (-6,-3)
Point T: (9,6)
Point S: (9,-3)
Now the easy part is done.
STEP 2: MULTIPLY BY 1/3
It is very important you know how to do this part because it determines the answer. So when i say "multiply by 1/3" i mean multiply each individual number by 1/3.
I'll explain for point u then do the rest:
Point U was originally: -6,6.
-6 x 1/3= -6/3= -2.
6x1/3= 6/3= 2
The "dilated" point U is: (-2,2). I multiplied each individual coordinate by 1/3, one by one.
Point R was originally: (-6,-3)
-6x1/3= -2
-3x1/3= -3/3= -1
The "dilated" point R is (-2,-1)
Point T was originally: (9,6)
9x1/3= 3
6x1/3= 2
The "dilated" point T is (3,2).
Point S was originally (9,-3).
9x1/3= 3
-3x1/3= -1
The "dilated' point S is (3,-1)
Finally, if you ever get confused about the order of the coordinates, it just stays the same. Like 9,-3 becomes the dilated 9 , dilated -3.
STEP 3: GRAPH THE NEW POINTS
see the screenshot, for reference :)
Answer:
Step-by-step explanation:
you dilate each coordinate by a scale factor of 1/3 , making the shape smaller.

11. Since Angle RST = 60 degrees, Angle RTS = 60 degrees.
Triangle STU is a right triangle, so Angle STU and Angle SUT are both 45 degrees.
Angle RTS + Angle STU + Angle UTQ = 180 degrees
60 + 45 + Angle UTQ = 180
Angle UTQ = 180 - 105

18. Doreen picked 2.33 kg of grapes. She gave 800 g of the grapes to her brother and then shared the remaining grapes equally with her two sisters. How many grams of grapes did each sister receive?
Answers
---------------------------------------︵‿︵‿୨♡୧‿︵‿︵--------------------------------------
Answer:
765 grams
Step-by-step explanation:
Exchange:
2.33 kg = 2330 gr
Grams of grapes that are left after giving 800 grams to her brother:
2330 - 800 = 1530 gr
Grams of grapes each sister will get if Doreen shares the remaining equally:
1530 : 2 = 765 gr
--------------------°✧° Pls mark me as °♡°(ꂧ ꁞ ꂧ)°♡° Brainliest °✧°--------------------
Because
2.33 kg = 2330 gr
Grams of grapes that are left after giving 800
grams to her brother:
2330 - 800 = 1530 gr
1530 divided by 2=765 qr

Answers
Answer:
Given:
I usually walk from home to work. This morning, I walked for 10 minutes until I was halfway to work.
I then realized that I would be late if I kept walking.
I ran the rest of the way. I run twice as fast as I walk.
Find:
The number of minutes in total did it take me to get from home to work
Step-by-step explanation:
Had I kept walking, the second half of my trip would have taken 10 more minutes.
By doubling my speed for the second half of my trip,
I halved the amount of time it took me to finish.
So, the second half of my trip took 5 minutes, for a total trip time of 10+5 = 15 minutes.
The number of minutes in total did it take me to get from home to work is 15 minutes.
20. 35 g of flour is used for making a muffin. Anajulie needs to prepare 700 muffins. She has 10.8 kg of flour. How much more flour does she need? Give the answer in kilograms.
Answers
Step-by-step explanation:
since for one muffins we need 20.35 g of flour
then for 700 muffins we need 20.35×700=14245g
14245g= 14.245kg
since she has 10.8kg then she needs extra (14.245-10.8)kg
=3.445kg
14245g= 14.245kg
(14.245-10.8) kg
=3.445kg

Answers
The original price was $66.64
Explanation:
The price is reduced by 55% so all the games are sold for 45%.
Let the cost of game be x,
45% × x = $29.99
0.45 × x = $29.99
x = $29.99/0.45
x = $66.644...
x = $66.64 (rounded to nearest cent)

Answer: 12.5 hours watching TV
Step-by-step explanation:
Step 1: We know this is an "in all" question, so we first need to find the fractions to add up.
Each dot on the graph represents 1 of each fraction. For example, the dot above the "1/4" means that 1/4 hours were spent watching TV, and the 3 dots above the 1 means that he watched TV for 1 hour in a row 3 times, so the total number of hours for 1 would be 3x1, or 1+1+1.
So we have:
1/4
1/2
3/4
3/4
3/4
1
1
1
1 1/4
1 1/4
1 1/4
1 1/4
1 1/2
(again, each dot represents 1 of each)
Step : Convert these to decimals so it's easier to add
1/4--> 0.25
1/2--> 0.5
3/4--> 0.75
3/4--> 0.75
3/4--> 0.75
1--> 1
1--> 1
1--> 1
1 1/4--> 1.25
1 1/4--> 1.25
1 1/4--> 1.25
1 1/4--> 1.25
1 1/2--> 1.5
0.25+0.5+0.75+0.75+0.75+1+1+1+1.25+1.25+1.25+1.25+1.5= 12.5 hours in all

Assuming the buses travel on the same highway, how many Dallas-bound buses does a Houston-bound bus pass on the highway (not in the station)?
Answers
Answer:
Assuming the buses travel on the same highway, the number of Dallas-bound buses does a Houston-bound bus pass on the highway is 10 buses.
Step-by-step explanation:
Given:
Buses from Dallas to Houston leave every hour on the hour. Buses from Houston to Dallas leave every hour on the half-hour.
The trip from one city to the other takes 5 hours.
Find:
Assuming the buses travel on the same highway, the number of Dallas-bound buses does a Houston-bound bus pass on the highway (not in the station)
Step 1 of 1
We count the number of Dallas-bound buses that a single Houston-bound bus passes.
There are two groups of Dallas-bound buses that we have to consider.
First, there are the buses that were on the way to Dallas at the time the Houston-bound bus leaves Dallas.
Second, there are the buses that leave Houston after the Houston-bound bus starts but before it arrives at Houston.
In order for a bus to be on the way to Dallas when the Houston-bound bus leaves, it must have left Houston less than 5 hours before the Houston-bound bus leaves.
There is one such bus each hour, for a total of 5 buses.
In order for a Dallas-bound bus to leave Houston after the Houston-bound bus leaves but before the Houston-bound bus arrives, the Dallas-bound must leave Houston within 5 hours after the Houston-bound bus leaves.
Again, there is one such bus each hour, for a total of 5 more buses than the Houston-bound bus passes.
Therefore, the Houston-bound bus passes 5+5=10 Dallas-bound buses.

G=266-42t and S=332-53t are equations to determine the number hours after noon t, when Genesis and Skylar are the same distance from the stadium
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Genesis is 266 miles away from the stadium.
Genesis is driving along the highway at a speed of 42 miles per hour.
Skylar is 332 miles away from the stadium.
Skylar is driving at speed of 53 miles per hour
Let G represent Genesis' distance, in miles, away from the stadium t hours after noon.
Let S represent Skylar's distance, in miles, away from the stadium t hours after noon.
We need to find an equation for each situation, in terms of t, and determine the number hours after noon t when Genesis and Skylar are the same distance from the stadium.
G=266-42t
S=332-53t
266-42t=332-53t
53t-42t=332-266
11t=66
Divide both sides by 11
t=6 hours
Hence, G=266-42t and S=332-53t are equations to determine the number hours after noon t, when Genesis and Skylar are the same distance from the stadium

20. The total mass of three boxes, A, B, and C, is 1.95 kg. The mass of Box A is 700 g. The mass of Box B is 4 times the mass of Box C. What is the mass of Box B in kilograms?
Answers
Answer:
Mass of B in Kg = -558.44kgStep-by-step explanation:
LET'S DO THIS!
Total mass of A, B and C = 1.95kg
Mass of A = 700 kg
Mass of B = 4x the mass of c (4 x C) which is 4c
Mass of C = ? ( let's call it C )
Adding all together700 + 4c + C = 1.95
Add like terms700 + 5C = 1.95
5C = 1.95 - 700
5C = -698.05
C = -698.05 ÷ 5
C = -139.61To find B now Remember they said B is 4 times the mass of C and C = -139.61therefore B = 4 × -139.61
B = -558.44 kg To check if we are correct, we add the masses of A, B and C to see if it equals their total mass which is 1.95kgUsing your calculator:= 700 + ( -558.44 ) + ( -139.61 )
= 700 - 558.44 -139.61
= 1.95 kg
Which makes us CORRECT ✅.
Hope this helps.Good luck ✅.Box A: 700g --> kg = 0.7kg
Box B: 4 x C
700 + 4C + C = 1.95kg
700 + 5C = 1.95kg
5C = 1.95 - 700
C = -698.05 divide by 5
C = -139.61
139.61 x 4 = -558.44kg

d. 75 is 75% of what number?
Answers
Answer:
75 is 75% of 100
Step-by-step explanation:
Simple explanation: Basically 75% is equal to 3/4 so if we find out how much 1/4 of the whole number is we can multiply it by 4 to get the whole number. Since 75 is 3/4 of the whole number we divide it by 3 which gives us 25 so 25 is 1/4 of the whole number. Afterwards we multiply it by 4 to get the whole number since 4/4 is 1 which is a whole.

When Paul crossed the finish line of a 60-meter race, he was ahead of Robert by 10 meters and ahead of Sam by 20 meters. Suppose Robert and Sam continue to race to the finish line without changing their rates of speed.
Find:
the number of meters by which Robert will beat Sam
Step 1 of 1
When Paul finishes, Robert has run 60-10=50 meters and Sam has run 60-20=40 meters.
Therefore, when Robert and Sam run for the same amount of time, Sam covers [tex]$\frac{40}{50}=\frac{4}{5}$[/tex] of the distance that Robert covers. So, while Robert runs the final 10 meters of the race, Sam runs [tex]$\frac{4}{5} \cdot 10=8$[/tex] meters.
This means Robert's lead over Sam increases by 2 more meters, and he beats Sam by 10+2=12 meters.
