Ribbon candy costs 2.50 per foot how many feet can you buy if you have 11.25
Answers
Solution :
Given that , Ribbon candy costs 2.50 per foot.
To calculate the length of Ribbon candy you can buy with 11.25, first you need to calculate the length of Ribbon candy you can buy with 1.
Solving it by Unitary Method,
In 2.50 you can buy 1 foot Ribbon candy,
In 1 you can buy [tex] \frac{1}{2.50} [/tex] foot Ribbon candy,
So, In 11.25 you can buy [tex] \frac{1}{2.50} \times 11.25 =4.5 [/tex]
Hece , In 11.25 you can buy 4,5 foot of ribbon candy.

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.

B. The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image.
C. The angles of the image are two-fifths the size of the angles of the pre-image.
D. The center of dilation is at point Q.
E. The base of the image is two-fifths the size of the base of the pre-image.
Answers
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.
As the images are similar , so Base of the image will be two fifths of the size of the base of preimage.
Option A,B and E are Correct.
A: The image is a reduction because n < 1.
B : The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image.

Mickey is 40 years old and has his retirement savings in a 401(k). If he makes $55,000 annually, what is the maximum percentage of his income that he can contribute to his 401(k) plan per year? (The current maximum contribution limit is $16,500.)
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]
[tex]\text{The maximum contribution percentage}=30\%[/tex]
Therefore, Mickey can contribute 30% of his annual income to his 401(k) plan at maximum.
What is the formula of quadratic equations?
Answers
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.

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.

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.

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.

Or none of these is correct
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.
Which equation is in slope-intercept form and represents a line with slope 3 through the point (9, –4)?
y=3x+21
y=3x-31
-3x+y=-31
-3x+y=21
Answers
[tex]y = mx + q[/tex]
Where m is the slope and y is the y-intercept:
[tex]y = 3x + q[/tex]
To find q (y-intercept), substitute the coordinates of the point (9, -4) in the equation of the line and solve it as an equation:
-4=3(9)+q
-4=27+q
q=-27-4=-31
The equation of the line is: y=3x-31
The equation in slope-intercept form representing a line with a slope of 3 and passing through the point (9, -4) is y = 3x - 31. This is found by substituting the point coordinates into the slope-intercept equation and solving for the y-intercept.
The question involves finding an equation in slope-intercept form that represents a line with a given slope that passes through a specific point. Slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept. Given the slope of 3 and the point (9,
–4), we can find the correct equation by substituting into the slope-intercept form and solving for b.
The correct equation must satisfy the condition that when x is 9, y is –4. Let's use this condition to solve for b:
y = mx + b
–4 = 3(9) + b
–4 = 27 + b
b = –4 - 27
b = –31
Therefore, the equation of the line is y = 3x – 31. This is the only equation among the choices that is in slope-intercept form and satisfies the given conditions.
