if you reflect fgh across the y-axis, what will be the coordinates of the vertices of the image f'g'h'
Answers
The correct answer is b.
Hope this helps =)
Therefore option B is correct.
What is reflection of coordinates?When a point is reflected across the line y = x, the x-coordinates and y-coordinates change their place. Similarly, when a point is reflected across the line y = -x, the x-coordinates and y-coordinates change their place and are negated. Therefore, The reflection of the point (x, y) across the line y = x is (y, x).
We have,
Coordinate of the vertex of the ΔFGH is F( -2 , -1 ) , G( 2 , 2 ) and H( 4 , -3 )
According to the question,
We know that when a point ( x , y ) reflected over y-axis , the y-coordinate remains the same but the x-coordinate is transformed into its opposite .i.e., ( -x , y )
So, Image of the Vertex F( -2 , -1 ) = F'( -(-2) , -1 ) = F'( 2 , -1 )
Image of the Vertex G( 2 , 2 ) = G'( -2 , 2 )
Image of the Vertex H( 4 , -3 ) = H'( -4 , -3 )
Hence, the image of the vertexes is F'( 2 , -1 ) ,G'( -2 , 2 ) and H'( -4 , -3 )

So I just wanna see if I got this one correct my question is.... Each volume of an encyclopedia is 2 1/3 inches wide. How many volumes will fit on a shelf 18 inches wide?
Answers
let's first convert the mixed fraction to "improper" and then do the division
[tex]\bf \stackrel{mixed}{2\frac{1}{3}}\implies \cfrac{2\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{7}{3}} \\\\\\ \cfrac{18}{\quad\frac{7}{3} \quad }\implies \cfrac{\frac{18}{1}}{\quad\frac{7}{3} \quad }\implies \cfrac{18}{1}\cdot \cfrac{3}{7}\implies \cfrac{54}{7}\implies 7\frac{5}{7}[/tex]
of course, you won't be chopping off a volume, so only the whole number will go from the quotient.
3. Use the description of each triangle to draw a picture of the triangle. Write and solve equations to find missing angle measures when necessary. Label the measures of all angles of the triangle and mark congruent sides and right angles. (You do not need to draw the triangle exactly to scale.) (a) right isosceles triangle (b) equiangular (all three angles congruent) isosceles triangle (c) acute scalene triangle with two angle measures of 57° and 82°
Answers
For part A, the right isosceles triangle, you must have a triangle with a right angle, 90 degree. Then, the two legs must be congruent.
For part D, draw a triangle with all 3 angles being 60. This will make the sides congruent also.
For part C, the three measures of your triangle will be 57, 82 and 41. The measures of the sides don't matter, they will all be different.
Rugs sell for $8 per square foot. Beth bought a 9-foot-long rectangular rug for $432. How wide was the rug?
Answers
The rug had an area of 54 ft²'
54 ÷ 9 = 6 ft
The rug had a width of 6 ft.
Divide 432 by 8 to find the square foot of the rug.
[tex]432 \div 8=54[/tex]
The rug has an area of 54 square foot.
The rug must have the shape of a rectangle.
The formula for the area of a rectangle is [tex]A=wl[/tex] where A is the area, w is the width, and l is the length.
We know the area and the length.
Plug it into the formula. You get the following.
[tex]9w=54[/tex]
Divide both sides by 9 to get the width.
[tex]w=6[/tex]
The width of the rug was 6 feet, which is the same as saying the rug was 6 feet wide. Hope this helps! :)

Because it's a fraction of a hole number, even less than half. Dilation point is V and it's 2/5 the original size.
the angles are Not different, and the center dilation point is not Q, there is no Q possibility in this picture.
Answer:
Dilation =[tex]\frac{2}{5}[/tex] was done on a rectangle.
→As Factor of Dilation is 0.4, which is less than 1.
→So, the image will be smaller in size than Pre image.
→As, the two rectangles , Pre image and image are similar so their sides will be proportional.
As in similar figures the interior angles are congruent.

E. The base of the image is two-fifths the size of the base of the pre-image.

Working together, it takes two roofers 10 hours to put a new roof on a portable classroom. if the first roofer can do the job by himself in 12 hours, how many hours will it take the second roofer to do the job by himself?
Answers
Number of hours the second roofer to do the job by himself is 60 hours.
Given that, working together, it takes two roofers 10 hours to put a new roof on a portable classroom.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Working together 1/10 roofs per hour
First roofer 1/12 roofs per hour
So, equation is x + 1/12 = 1/10
x = 1/10 - 1/12
= 6/60 - 5/60 = 1/60
Together, they work 1/60 + 1/12
= 1/60 + 5/60
= 6/60 = 1/10
Therefore, number of hours the second roofer to do the job by himself is 60 hours.

Answers
The first choice is the correct one.
Final answer:
The numbers 12,089 is less than 12,098, as determined by comparing the ones place of each number., hence the correct option is A
Explanation:
The student asks for the correct comparison between the numbers 12,089 and 12,098. To generate an accurate answer, we compare the digits from left to right.
Since the thousands, hundreds, and tens places are the same, we look at the ones place to determine which number is greater. Comparing the ones digits, we see that 9 (in 12,098) is greater than 8 (in 12,089), therefore 12,089 is less than 12,098.
The correct answer is:
12,089 < 12,098.

Final answer:
The quadratic formula is used to find the solutions of quadratic equations. It is x = (-b ± √(b² - 4ac)) / (2a). The discriminant determines the nature of the solutions.
Explanation:
The formula for quadratic equations is:
x = (-b ± √(b² - 4ac)) / (2a)
Quadratic equations are equations of the form ax² + bx + c = 0. The quadratic formula is used to find the solutions or roots of these equations. The discriminant, b² - 4ac, determines the nature of the solutions: if it is positive, there are two real solutions; if it is zero, there is one real solution; and if it is negative, there are two complex solutions.

You have 10 cups of a cleaning solution that is 10% white vinegar and 90% water. You want the mixture to be 50% white vinegar and 50% water. How many cups of white vinegar do you need to add to the mixture?
Answers
x-->volume of white vinegar you need to add to the mixture (measured in cups)
then
the amount of the pure vinegar in the mixture will be -----> (10*0.1 + x) cups
the volume of liquid will be ---------> 10 + x
the concentration equation is-------> [(10*0.1 + x)/(10+x)]=0.50multiply both sides by (10+x) and then simplify
(10*0.1 + x)=(10+x)*0.50-----------> 1+x=5+0.50x-------> 0.50x=4
x=8
the answer is
you need to add 8 of a cup of the pure vinegar to the mixture
To change a mixture that is 10% vinegar and 90% water to a 50-50 mixture, one would have to add 8 more cups of vinegar. This is because there are already 9 cups of water in the 10 cup solution, so adding 8 more cups of vinegar will total to 9 cups of vinegar and 9 cups of water.
Explanation:This question can be tackled using a simple mathematical approach. You already have a mixture that is 10% vinegar and 90% water, which means you have 1 cup of vinegar in your 10 cups of solution (because 10% of 10 cups is 1 cup). To get a 50-50 mixture, you also need the amount of water to equal the amount of vinegar. Since you already have 9 cups of water in the solution, you need to add 8 more cups of vinegar to balance it out and get a 50% solution. So you'll need to add 8 cups of white vinegar to your mixture in order to attain a balance of 50% vinegar and 50% water.

Answers
Answer:
30%.
Step-by-step explanation:
We have been given that Mickey makes $55,000 annually and the current maximum contribution limit to 401(k) plan is $16,500. We are asked to find the maximum percentage Mickey can contribute of his 401(k) plan.
To find the maximum contribution percentage, we need to figure out $16,500 is what percent of $55,000.
[tex]\text{The maximum contribution percentage}=\frac{\$16,500}{\$55,000}\times 100[/tex]
[tex]\text{The maximum contribution percentage}=0.30\times 100[/tex]

A.5/11
B.5/10
C.5/100
D.2/1
Answers
5/10
Selection B is appropriate.
Answer:
The correct option is B.
Step-by-step explanation:
The given number is 0.5.
If a number can be defined as a/b where b≠0, then it is called a rational number.
We need to rewrite the given number in the form of a/b using integers.
Multiply and divide the given number by 10 to remove the decimal from the given number.
[tex]0.5\times \frac{10}{10}[/tex]
On simplification we get
[tex]\frac{0.5\times 10}{10}[/tex]
[tex]\frac{5}{10}[/tex]
Here a=5 and b=10 both are integers.
The given number 0.5 is a ration number because it can be written as 5/10.
Therefore the correct option is B.
