The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

What is the greatest number less than 400 such that 4 is the greatest common divisor of the number and 24?
Answers
Answer:
its simple greatest number less that 400 is 399
Answer:
388
Step-by-step explanation:
Definition from Wikipedia
In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted as gcd(x,y) . For example, the GCD of 8 and 12 is 4, that is, gcd(8,4)=4 (https://en.wikipedia.org/wiki/Greatest_common_divisor)
Methodology to find greatest common denominator(factor) for 2 numbers
Write down the divisors of both numbersCollect the common divisors of both termsChoose the largest divisor from the above termsThe divisors of 24 are 1, 2, 3, 4, 6, 8, 12, 24Since the number is less than 400, it must be 4 x D where D < 100Let's try 4 x 99 = 396. Divisors are 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396. gcd(24, 396) = 12.Try D = 98 ==> 4 x 98 = 392 with divisors 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392. gcd(24, 392) = 8Try D = 97 ==> 4 x 97 = 388. Divisors of 388 are 1, 2, 4, 97, 194, 388 gcd(4, 388) = 4Note that even though I have listed all divisors of the higher number, you don't have to compute all divisors. You can stop figuring out the divisors once the larger number is divisible by the number that is higher than 4 but slosest to i. For example, in the case of 396, I would stop computing as soon as I found it is divisible by 6

The formula for the volume of a cylinder is V=\(\pi r^{2} h\)h, where V is the volume, r is the length of the radius of the base, and h is the height of the cylinder.
Answers
Answer: The volume for a cylinder is pi times radius squared multiplied by height. If the radius for the base of a cylinder is 2 inches, and its height is 8 inches, we square our radius 2 and get 4. Then we multiply this by pi which would be 3.14, to get 12.56. Then we multiply the product by height (8), 12.56 times 8, is 100.48 inches which is the volume of the cylinder.
Step-by-step explanation:
The formula to calculate the volume of a cylinder is:
\(\boldsymbol{\sf{V=\pi r^{2}h }}\), where
V = VolumeR = radiusH = Heightπ = PThe cylinder has radius and height.
To calculate the volume, we substitute the data in the formula, which are the radius and the height.
First calculate the radius squared. Then the value of PI is multiplied, which the value is 3.14 by the radius in cm^2 by the height. And in this way the volume of the cylinder will be calculated.

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $1790 and his stock in Company B was worth $1000. The stock in Company A has increased 20% since last year and the stock in Company B has increased 22%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).
Answers
Answer:
20.7%
Step-by-step explanation:
Amount of stock increased in Company A = 20% of 1790
= 0.20 * 1790 = $ 358
Investor's stock in company A this year = 1790 + 358 = $ 2148
Amount of stock increased in Company B = 22% of 1000
= 0.22 * 1000= $ 220
Investor's stock in company B this year = 1000 + 220 = $ 1220
Total amount in investor's stock account = 2148 + 1220 = $ 3368
Increased amount = 3368 - 2790 = $ 578
Increase percentage = \(\frac{578}{2790}*100\) = 20.71
= 20.7%

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

C. -18. 6+(-16. 8)
D. 16. 8+(-18. 6)
Answers
Answer: Answer is D
Step-by-step explanation:
which expression has a value of 6 when x=2 and y=4?
Answers
refer to picture for steps
Let's verify all the options to the question. Clue given: x = 2, y = 4
Option A:
(x² + 8) ÷ y - 2
=> (2² + 8) ÷ 4 - 2
=> (4 + 8) ÷ 4 - 2
=> 12 ÷ 4 - 2
=> 3 - 2
=> 1 ≠ 6
This answer does not equal 6.
Option B:
(x² + 8) ÷ (y - 2)
=> (2² + 8) ÷ (4 - 2)
=> (4 + 8) ÷ (4 - 2)
=> 12 ÷ 2
=> 6 = 6
This answer is correct as 6 = 6.
Option C:
x² + 8 ÷ (y - 2)
=> 2² + 8 ÷ (4 - 2)
=> 4 + 8 ÷ 2
=> 4 + 4
=> 8 ≠ 6
This answer does not equal 6.
Option D:
x² + 8 ÷ y - 2
=> 4 + 8 ÷ 4 - 2
=> 4 + 2 - 2
=> 4 ≠ 6
This answer does not equal 6.
So, after verifying all our options, we can conclude that Option B is correct. Therefore, Option B is the correct answer.

= -15
Now, take any of the given points and substitute the values

We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
