△R′S′T′ is the image of △RST under a dilation through point C. RS=5 and R′S′=8 . What scale factor was used in the dilation?
Answer:
1.6
Step-by-step explanation:
To find the scale factor, we compare the image size to the pre-image size.
R'S' = 8 and RS = 5; this makes the scale factor 8/5, which is 1.6.
Dilation is a transformation that allows you to resize an object. Dilation is a technique for making items bigger or smaller. The scale factor that was used in the dilation is 1.6.
What is dilation?Dilation is a transformation that allows you to resize an object. Dilation is a technique for making items bigger or smaller. This transformation yields a picture that is identical to the original shape. However, there is a size discrepancy in the form.
Scale factor = Dimension of the new shape/Dimension of the original shape
Given that △R′S′T′ is the image of △RST under a dilation through point C. Also, given that RS=5 and R′S′=8. Therefore, the scale factor that was used in the dilation is,
Scale factor = Dimension of the new shape/Dimension of the original shape
Scale factor = R′S′ / RS = 8/5
= 1.6
Hence, the scale factor that was used in the dilation is 1.6.

Diana received $35 worth in Starbucks gift cards for Christmas her favorite drink caramel macchiato costs about $4:00 help diana keep track of the balance left in her gift cards each time she buys a drink how many caramel macchiato will she be able to buy with her gift cards?
Diana can buy a total of 8 caramel macchiatos with her $35 Starbucks gift cards, and she will have a remaining balance of $3.
To help Diana keep track of the balance on her Starbucks gift cards after purchasing her favorite drink, the caramel macchiato, we need to perform a series of simple subtractions. She starts with a $35 balance, and each caramel macchiato costs $4.00.
After buying the first caramel macchiato, the new balance is $35 - $4.00 = $31.
After the second purchase, $31 - $4.00 = $27.
This process continues until the balance is less than the cost of a caramel macchiato.
To find out how many drinks she can purchase in total, we divide the initial balance by the cost of one caramel macchiato:
$35 / $4.00 = 8.75
Since she cannot buy a fraction of a drink, Diana can buy a total of 8 caramel macchiatos with her gift cards and will have a remaining balance of $3, which is not enough for another drink.

Look at the diagram. Which of the following is another name for < 1
A. < CBA
B. < ACB
C. < CAB
D. < BAC
Answer: A. ∠CBA
Step-by-step explanation:
We need three points to write a name of an angle. One point on each ray with the vertex lies in the middle.
There are total three ways to write a name of an angle.
For example :- M and N are points on each ray of an angle with vertex O.
Then, the name of angle can be ∠O, ∠MON or ∠NOM.
From the given picture , it can be observe that A and C are points on each ray of ∠1 with vertex B.
Then, the possible name of ∠1 will be ∠B , ∠ABC or ∠CBA.
Since, ∠CBA in given in option A.
Thus OPTION A is the correct option.

Which is the best simplification of (24 x 32) / (2 x 3)?
To simplify (24 x 32) / (2 x 3), perform the multiplication operations first. Then perform the division operation. This results in the simplification of the given expression to 128.
Explanation:To simplify the expression (24 x 32) / (2 x 3), we'll first carry out the multiplication operations because of the BIDMAS or PEMDAS rule that gives the order of operations in maths. B or P stands for brackets, I or E stands for Indices or Exponents, D/M for Division/Multiplication and A/S for Addition/Subtraction. According to this rule, Division or Multiplication is performed from left to right. Therefore, we first multiply 24 x 32 which gives 768, and secondly multiply 2 x 3 which gives 6. Thus, the expression now becomes 768 / 6. This division gives us the final answer of 128.

What is the area of a circle with a diameter of 13.2 cm?
Use 3.14 for pi and round your final answer to the nearest hundredth.
Enter your answer in the box.
Which explanation can be used to derive the formula for the circumference of a circle?
A. Find the length of the diameter and double this amount. Subtract it from the length of the circumference. Set an equation to show the difference equaling the ratio between a circumference and radius. Then rearrange the equation to solve for the circumference.
B. Find the length of the radius. Then find the circumference. Use the square of the radius to set up an equation showing the relationship that the square of the radius equals the π times circumference. Then rearrange the equation to equal the circumference.
C. Find the length of the radius and the area of the circle. Divide the area by the radius to get a quotient of π . Write an equation showing the area of a circle equals this quotient times the radius. Then substitute the area for 3 times the circumference and rearrange the equation to equal the circumference.
D. Find the length of the diameter and the length of the circumference of the circle. Divide the length of the circumference by the length of the diameter. Set up an equation showing the ratio of the circumference to the diameter equal to π . Then rearrange the equation by solving it for the circumference. Substitute 2 times the radius for the diameter.

One week, the music store sold 2 trumpets, 3 clarinets, and 5 violins for $1240. the next week, they sold 3 trumpets, 1 clarinet, and 4 violins for $1027. the following week, they sold 5 trumpets, 7 clarinets, and 2 violins for $2091.
Let x be the cost of trumpets
y be the cost of clarinets
z be the cost of violins
Now we frame equations
2x +3y + 5z = 1240 ---> equation 1
3x + 1y + 4z = 1027---> equation 2
5x + 7y + 2z = 2091 ---> equation 3
Now we solve for x,y and z using elimination method
Multiply the second equation by -3 and with first equation
2x +3y + 5z = 1240
-9x - 3y -12z = -3081
--------------------------------
-7x - 7z = -1841 ( divide both sides by -7)
x + y = 263 ----------> equation 4
Multiply the second equation by -7 and add it with third equation
-21x - 7y - 28z = -7189
5x + 7y + 2z = 2091
------------------------------------
-16x - 26z = -5098 (divide the whole equation by -2)
8x + 13z = 2549 --------> equation 5
Now use equation 4 and 5 to eliminate x. Multiply equation 4 by 8
-8x - 8z = -2104
8x + 13z = 2549
------------------------------
5z = 445
z = 89
We know x + z = 263, replace z with 89
x + 89 = 263 ( subtract 89 on both sides)
x = 174
2x +3y + 5z = 1240 ---> equation 1 ( substitute the values of x and z)
2(174) + 3y + 5(89) = 1240
348 + 3y + 445 = 1240
793 + 3y = 1240 ( subtract 793 on both sides)
3y = 447 ( divide by 3 on both sides)
y = 149
The cost of trumpets = $174
The cost of clarinets = $149
The cost of violins = $89
Using a system of equations, it is found that:
The cost of a trumpet is of $174.The cost of a clarinet is of $149.The cost of a violin is of $89.------------------
For the system of equations, i will say that:
The cost of a trumpet is x.The cost of a clarinet is y.The cost of a violin is z.------------------
2 trumpets, 3 clarinets, and 5 violins for $1240, thus:
[tex]2x + 3y + 5z = 1240[/tex]
3 trumpets, 1 clarinet, and 4 violins for $1027, thus:
[tex]3x + y + 4z = 1027[/tex]
5 trumpets, 7 clarinets, and 2 violins for $2091, thus:
[tex]5x + 7y + 2z = 2091[/tex]
------------------
From the second equation:
[tex]y = 1027 - 3x - 4z[/tex]
Replacing into the other two:
[tex]2x + 3y + 5z = 1240[/tex]
[tex]2x + 3(1027 - 3x - 4z) + 5z = 1240[/tex]
[tex]-7x - 7z = -1841[/tex]
Simplifying by 7:
[tex]x + z = 263 \rightarrow z = 263 - x[/tex]
Also:
[tex]5x + 7y + 2z = 2091[/tex]
[tex]5x + 7(1027 - 3x - 4z) + 2z = 2091[/tex]
[tex]-16x - 26z = -5098[/tex]
[tex]16x + 26z = 5098[/tex]
------------------
Solving for x:
[tex]16x + 26z = 5098[/tex]
[tex]16x + 26(263 - x) = 5098[/tex]
[tex]10x = 1740[/tex]
[tex]x = \frac{1740}{10}[/tex]
[tex]x = 174[/tex]
The cost of a trumpet is of $174.
------------------
Solving for z:
[tex]z = 263 - x = 263 - 174 = 89[/tex]
The cost of a violin is of $89.
------------------
Solving for y:
[tex]y = 1027 - 3x - 4z = 1027 - 3(174) - 4(89) = 149[/tex]
The cost of a clarinet is of $149.

Answer:
40 fluid ounces of lemonade.
Step-by-step explanation:
Amanda uses the recipe shown to make punch for a family party.
Amanda's punch recipe 7 parts mixed fruit juice 2 parts lemonade.
7 + 2 = 9 parts
She will need to make 180 fluid ounces of punch.
she will need lemonade = (180/9) × 2
= 20 × 2
= 40 fluid ounces lemonade
She will need fruit juice = (180/9) × 7
= 20 × 7
= 140 fluid ounces fruit juice.
Amanda will need 40 fluid ounces lemonade to make 180 fluid ounces of punch.
