Bookstore A sells a particular book for $15.25, but they have it on sale for 20% off. Bookstore B sells it for $12.45. How much more does it cost at Bookstore B?
Answer:
$0.25
Step-by-step explanation:
to find the amount bookstore A sales after the 20% discount, cross multiply x/15.25=20/100 and you get $3.05. 15.25-3.05 gives you $12.2. substract 12.2 from 12.45 and you get $0.25. book B costs $0.25 more than book A.

Old Farmer MacDonald wants to build a pen to keep his chickens in. He has 36 meters of fence and plans to make a rectangular pen. Complete the chart to help Old MacDonald decide how to make his chicken pen so that he has the maximum area.
Answer:
2 = 18
4 = 9
6 = 6
8 = 4.5
10 = 3.6
12 = 3
14 = 2.57 (2.6 simplified)
16 = 2.25 (2.3 simplified)
Step-by-step explanation:
You can solve this by dividing 36 (the whole amount of meter of fences)
by each number of the length
area width
36 divided by 2 = 18
36 divided by 4 = 9
36 divided by 6 = 6
36 divided by 8 = 4.5
36 divided by 10 = 3.6
36 divided by 12 = 3
36 divided by 14 = 2.57 (2.6 simplified)
36 divided by 16 = 2.25 (2.3 simplified)

right rectangular prism has a square base with sides that are 7 meters in length. The height of the prism is 15 meters. Find the volume of the prism in cubic meters.
Answer:
The volume of the prism V = 735 cubic meters
Step-by-step explanation:
Explanation:-
Given that length of the rectangular prism(l) = 7 m
and also the width of the rectangular prism(w) = 7 m
The height of the rectangular prism = 15 m
The volume of the prism
V = l× w × h
V = 7 × 7× 15
V = 735 cubic meters
The volume of the prism V = 735 cubic meters
To complete a task in 15 days, a company has 4 people each working 8 hours a day. The company
decide to have 5 people each working 6 hours a day. Assume that each person works at the same
rate.
a) How many days will it take the 5 people to complete the task?
b)Comment on how the assumption affects your answer to part (a).
Answer:
Let's suppose that each person works at an hourly rate R.
Then if 4 people working 8 hours per day, a total of 15 days to complete the task, we can write this as:
4*R*(15*8 hours) = 1 task.
Whit this we can find the value of R.
R = 1 task/(4*15*8 h) = (1/480) task/hour.
a) Now suppose that we have 5 workers, and each one of them works 6 hours per day for a total of D days to complete the task, then we have the equation:
5*( (1/480) task/hour)*(D*6 hours) = 1 task.
We only need to isolate D, that is the number of days that will take the 5 workers to complete the task:
D = (1 task)/(5*6h*1/480 task/hour) = (1 task)/(30/480 taks) = 480/30 = 16
D = 16
Then the 5 workers working 6 hours per day, need 16 days to complete the job.
b) The assumption is that all workers work at the same rate R. If this was not the case (and each one worked at a different rate) we couldn't find the rate at which each worker completes the task (because we had not enough information), and then we would be incapable of completing the question.

The length of a rectangle is shown below: On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair 1, 2, and the point B is on ordered pair negative 3, 2. A straight line joins the points A and B. If the area of the rectangle to be drawn is 12 square units, where should points C and D be located, if they lie vertically below the line that connects B and A, to make this rectangle?

Answer:
C. 24
Step-by-step explanation:
Q is the centroid of the triangle. This means that the interior lines are medians, the special rule for medians when they intersect within a triangle is that each line is split into exactly 2/3s and 1/3. So the side of the median closer to the vertex will be exactly double the shorter side. Therefore, if AD is 36, find 2/3s of that to get AQ. An easy way to do this is to divide 36 by 3, which is 12, and then multiply that by 2, which gives you the final answer, 24.
Triangle XYZ has vertices X(-1, -3), Y(0, 0), and Z(1, -3). Malik rotated the triangle 90° clockwise about the origin. What
is the correct set of image points for triangle X'Y'Z?
O X (3, -1), Y'(0, 0), Z (3, 1)
O X'(1, 3), Y'(0, 0), Z'(-1,3)
O X'(1, -3),Y (0, 0), Z'(-1, -3)
O X(-3, 1), Y'(0, 0), Z'(-3,-1)
Answer:
a
Step-by-step explanation:
Transformation involves changing the vertices of a shape
The correct set of image points for triangle X'Y'Z is X'(-3,1), Y'(0, 0), Z'(-3,-1)
The vertices of the triangle are given as:
X(-1, -3), Y(0, 0), and Z(1, -3)
The rule of rotation is given as: 90 degrees rotation about the origin.
This is represented as:
[tex](x,y) \to (y, -x)[/tex]
So, we have:
X'(-3,1), Y'(0, 0), and Z'(-3,-1)
Hence, the correct set of image points for triangle X'Y'Z is X'(-3,1), Y'(0, 0), Z'(-3,-1)
