Two similar triangles are shown on the following coordinate grid:
A coordinate plane is shown. Triangle ABC has vertices A at negative 3 comma 2, B at negative 1 comma 0, and C at negative 2 comma negative 1. Triangle A prime B prime C prime has vertices A prime at 6 comma 4, B prime at 2 comma 0, and C prime at 4 comma negative 2.
Which set of transformations has been performed on triangle ABC to form triangle A′B′C′?
A. Dilation by a scale factor of 4 followed by reflection over the x-axis
B. Dilation by a scale factor of 2 followed by reflection over the x-axis
C. Dilation by a scale factor of 4 followed by reflection over the y-axis
D. Dilation by a scale factor of 2 followed by reflection over the y-axis
Answer:
Reflection across the y-axis and a dilation by a factor of 2.
Step-by-step explanation:
Comparing the points from the pre-image, ABC, to the image, A'B'C', we see that both x- and y-coordinates seem to be doubled from the pre-image to the image. However, the sign of the x-coordinates in the image is different; this means that the x-coordinates are negated. A reflection across the y-axis will negate the x-coordinates.
To double both the x- and y-coordinates, we would then apply a dilation by a factor of 2, as the scale factor gets multiplied by every coordinate.

A baseball player got 102 hits in the last 300 times at bat. Explain how you would find the percent of times at bat.
Answer:
34%
Step-by-step explanation:
Divide the number of hits, 102, by the times at bat, 300. Then move the decimal 2 places to the right and add the percent sign to get 34%.
Answer:
34%
Step-by-step explanation:
You would cross mulitply to find the answer.
[tex]\frac{102}{300}[/tex] x [tex]\frac{x}{100}[/tex]
multiplying that out would equal
300x = 10200
then find x by dividing 10200 by 300
you get x=34 and 34 out of 100 is 34%

During another part of its flight the balloon in Exercise 10 had a change in elevation of -901 feet in 34 minutes. What was its rate of decent
Answer: 26.5 ft per minute
Step-by-step explanation:
The hot air balloon descended 901 feet in 34 minutes.
The rate at which it was descending can be calculated by the speed formula which is:
= Distance descended / time
= 901 / 34
= 26.5 ft per minute
If there are 104 ounces in 2 quarts, how many quarts are there in 260 ounces?
Answer:
5
Step-by-step explanation:
104 oz = 2 q
divide by 2
52 oz= 1 q
now take 260 oz / 52 oz
5 quarts
Unit conversion is a way of converting some common units into another without changing their real value. There are 5 quarts in 260 ounces.
What is unit conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
Given that there are 104 ounces in 2 quarts. Therefore, the number of ounces in a quart can be written as,
Number of ounces in quart = 104 ounces / 2 quarts
= 52 ounces per quart
Now, the number of quarts that are in 260 ounces is,
Number of quarts = 260 ounces / 52 ounces per quart
Number of quarts = 5 quarts
Hence, there are 5 quarts in 260 ounces.

A. Curve
B. Straight line
C. A V-shape
D. Parabola
Answer:
straight line
Step-by-step explanation:
The graph of the given line is a Straight line.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
Given that, an equation, y = 6x-1, we need to tell what type of graph will it make,
y = 6x-1
Put x = 0,
y = -1
Put x = 1
y = 5
Put x = 0.5
y = 2
Points =
x = 0, 1, 0.5
y = -1, 5, 2
Plotting the graph, we will get a straight line, also, we know that, a linear equation will always make a straight line,
Hence, the graph of the given line is a Straight line.

18. Find the equation of the circle containing the points (-1.-1) and (3, 1) and with the centre on the line x-y + 10 = 0
Answer:
x^{2} +2x+y^{2}+2y= 18
Step-by-step explanation:
equation of circle is:
[tex]x^{2}+y^{2}=r^{2}[/tex]
using distance formula and substituting value,
[tex](3-(-1))^{2} +(1-(-1))^{2}=r^{2}[/tex]
solving,
r=[tex]2\sqrt{5}[/tex]
for equation of circle,
[tex](x-(-1))^{2} +(y-(-1))^{2} =20[/tex]
on solving,
[tex]x^{2} +2x+1+y^{2}+2y+1=20[/tex]
on solving,
[tex]x^{2} +2x+y^{2}+2y= 18[/tex]
Mill Road Elementary school has 525 students but expects that to decrease by 4% next year. How many students do they expect to have next year?
Answer:
They expect to have 504 students next year.
Step-by-step explanation:
In order to find the answer, you have to calculate the 4% of the number of students the school has and subtract that amount from the number of students to get the amount of students they expect to have next year as they expect that to decrease:
525*4%=21
525-21=504
According to this, the answer is that they expect to have 504 students next year.

Use the original price and the markdown or markup to find the retail price. Original price $43; markup 11.5%
Answer:
$47.945
Step-by-step explanation:
Given the following
Original price = $43;
markup = 11.5%
Markup price = 11.5% of the original price
Markup price = 11.5% of $43
Markup price = 0.115×43
Markup price = $4.945
Retail price = original price+markup price
Retail price = $43+$4.945
Retail price = $47.945
