Step-by-step explanation:
Which of the following describes the image of a triangle after a dilation that has a scale factor of 2/3?
A.-Each angle has 2/3 of the measure of its corresponding angle in the pre-image
B.-Each side has the same measure as its corresponding angle in the pre-image.
C.-Each angle has the same measure as its corresponding angle in the pre-image.
D.-Each side has 3/2 the length of its corresponding length in the pre-image.
We want to see which statement describes the image of a triangle after a dilation of scale factor of 2/3.
We will see that the correct option is C:
"Each angle has the same measure as its corresponding angle in the pre-image."
First, if we have a given figure and we apply a dilation of scale factor K, then all the measures of the given figures are affected by that dilation.
So if the 3 sides of the original triangle measured A, B, and C.
The new measures will be:
C' = k*CB' = k*BA' = k*ANotice that because all the sides changed proportionally, then the internal angles produced did not change after the dilation.
From this, we can conclude that the only correct option is C:
"Each angle has the same measure as its corresponding angle in the pre-image."
This says that the angles of the dilated triangle are the same ones as the angles of the initial triangle, which is true.

In Earth's southern hemisphere, the summer season is from December to March and winter is from June to September. The table shows the highest temperatures recorded at the South Pole for three different months.
Graph model:
South Pole Temperatures
Month Highest temperature (°F)
January 6
June –24
November –2
Each month's highest recorded temperature is plotted on the number line.
4. Which month had the coldest of the three temperatures? Explain.
#4
June is the most coldest.
How?
Mention the temperatures
January=+6°F
June=-24°F
November=-2°F
Lowest is the coldest .(June is the coldest month)
January = 6°F
June = -24°F
November = -2°F
By the above given observation we can say that June is the coldest as it has the lowest temperature in all.

Answer:
The equation you would graph would be y=-4 +x or y= x-4 (basically the same thing)
y=0 then x would equal 4
Step-by-step explanation:
y=-4+x x-y=4
0=-4+x -x -x
+4 +4 -y= 4-x
4=x /-1 /-1
y= x -4

Drew and Danielle are sightseeing for the day. Between the two of them they take 118 pictures. If Drew takes 14 more than three times as many pictures as Danielle, how many pictures for each friend take?
Answer:
Drew = 92 pictures, Danielle = 26 pictures
Step-by-step explanation:
Amount of pictures Drew has = x
Amount of pictures Danielle has = y
First make a system of equations:
x + y = 118
x = 3y + 14
Then solve with substitution:
(3y + 14) + y = 118
4y = 104
y = 26
x + 26 = 118
x = 92

Hope it helps...What is 19% of 41?
(Simplify, no links)
Answer:
7.79
Step-by-step explanation:
19 percent of 41 is the same as 19 per hundred of 41. We can therefore make the following equation:
19/100 = X/41
To solve the equation above for X, you first switch the sides to get the X on the left side, then multiply each side by 41, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:
19/100 = X/41
X/41 = 19/100
X*41/41 = 19*41/100
X = 779/100
X = 7.79
The work above shows the long way to explain how to calculate 19 percent of 41 in order to give you a foundation and better understanding of how to calculate the percentage. In the future, you could use this simplified formula:
(Y * P)/100
In our problem "What is 19 percent of 41?", Y is 41 and P is 19:
(41 * 19)/100 = 7.79
And once again you see that the answer is 7.79.

A bus pass has a starting value of $100. After one ride, the value of the pass is $98.25. After two rides, its value is $96.50. After three rides, its value is $94.75.
1. Write a rule to represent the remaining value on the card as an arithmetic sequence.
# of Rides Bus Pass Value Rule
0 $100.00
1 $98.25
2 $96.50
3 $94.75
15 _____
2. What is the value of the pass after 15 rides?
3. How many rides can be taken with the $100 pass? (hint: set up an equation y=mx+b using the cost per ride as your NEGATIVE “m” value because your value goes down each time you ride and $100 as your starting “b” value. We’re solving for x when the total is 0. So, 0 = -___x + 100, fill in the blank with the cost per ride and solve for x.)
Answer:
73.75
Step-by-step explanation:
every ride the bus pass value goes down by 1.75 so we can use that to figure out what the 15th ride would cost. if you multiply 1.75 x 15 you will get 26.25. Now subtract 26.25 from 100 to get 73.75. Hope i helped! :)
Help! I’ll mark brainly list but please explain!!
Answer:
9.75, 2, and 56.25
Step-by-step explanation:
Since it's 4 movie tickets, 2 popcorns (which are $6.25),
4(9.75) + 2(6.25 -> Popcorn) + 4.75
= 39 + 12.5 + 4.75
= 39 + 17.25
= $56.25
As for the total cost,
4 * 9.75 = 39
2 * 6.25 = 12.5
1 * 4.75 = 4.75

One angle be x
other is 2x-6ATQ
[tex]\\ \sf\longmapsto x+2x-6=90[/tex]
[tex]\\ \sf\longmapsto 3x-6=90[/tex]
[tex]\\ \sf\longmapsto 3x=96[/tex]
[tex]\\ \sf\longmapsto x=32[/tex]
[tex]\\ \sf\longmapsto 2x-6=2(32)-6=58°[/tex]
Answer:
58°
Step-by-step explanation:
The measure if one 2 complementary angle is 6 less than the measure of the other => x + 2x - 6° = 90°
x + 2x - 6° = 90°
3x = 90° + 6°
3x = 96°
x = 96° : 3
x = 32°
Substitution :
2x - 6°
= 2 × 32° - 6°
= 64° - 6°
= 58°

Answer:
24 cars
Step-by-step explanation:
By using 11 cars and AED 79.75, you can find out the cost of washing 1 car.
(AED 79.75)/(11 cars) = AED 7.25 / car
Now we divide AED 174 by AED 7.25/car to find the number of cars.
(AED 174) / [(AED 7.25)/car] = (174/7.25) cars = 24 cars
Answer: 24 cars

Trey is buying a computer on
sale. The origina Price was
4200. If the sale price is 5/6 of
the original Price . How much did
trey pay for the computer?
Answer:
3500
Step-by-step explanation:
To find a fraction of something just keep in mind that "of" means to multiply (when dealing with fractions and percents). In this case we want to know what 5/6 of 4200 is. So do (5/6)*4200 and that equal 3500.
