Problem 14
Answer: They bought too much sand-----------------------
Explanation:
Because the sandbox is a rectangular prism, aka a block, we multiply the length width and height to get the volume.
Volume = length*width*height = 6*5*1.2 = 36
The volume of the sandbox is 36 cubic feet.
The customer bought 40 cubic feet of sand, which exceeds the volume we computed earlier. The customer bought too much sand.
If it was a choice of buying too much or too little, I think it's better to go overboard just so you don't have to return to the store. The extra amount of sand (40-36 = 4 cubic feet) can possibly sold or donated at a later time.

Problem 15
Answers:The equation could be 306.52 = 19.4h or 19.4h = 306.52Either equation mentioned solves to h = 15.8; so the height of the prism is 15.8 meters-----------------------
Explanation:
The rectangular prism formula to calculate the volume is
Volume = length*width*height
Note that the portion "length*width" can be replaced with "base area", because the base area is a rectangle.
So we can have this alternative formula
Volume = (base area)*height
If we know the area of the floor, and multiply by the height of the wall, then we can calculate the volume of a room like this. In this case, the floor is 19.4 square meters in area. The overall room is 306.52 cubic meters. We'll let h be the height of the wall. Use algebra to solve for h
Volume = (base area)*height
306.52 = 19.4h .... is one equation to set up
19.4h = 306.52
h = 306.52/19.4
h = 15.8
We divide both sides by 19.4 to undo the multiplication going on.
The height of the prism is 15.8 meters.

Answer:

Step-by-step explanation:
Look at both trapezoids and you can find the relation between both
Line DC and GH are equal, those different measurements they have the same characteristics. Same with AB and FE
Divide GH by DZ and you get the scale that you can apply to find FE
30/7.5 = 4
So line FE is 4 times smaller than AB
24/4 = 6

Answers
Answer:
let's say x1 = y2. for instance, that would mean that for every X, y would go up by 2. That would mean -1x = Y-2 because to get to -1 you have to subtract 1 by 2 because there is still 0 to account for.
so the table would look like this

-1=-2
1=2

Answer:
Angle RUQ is greater than angle TUR
Step-by-step explanation:
Angle TUR is a total of 125 degrees and angle RUQ is a total of 145 degrees. You find the measure of RUQ by subtracting 35 degrees from 180 degrees, this will give you the 145 degrees. So angle RUQ is greater than angle TUR by 20.

Kelly paid $45.36 for a sweater that was on sale for 25% off the original price. She paid 8% sales tax on the sale price.
What was the original price of the sweater, in dollars?
(Please explain your answer if you want, I would appreciate and give brainliest if you do so.)
Answers
The original price of the sweater, in dollars is $52.1648.
What is meant by percentage of a value ?Percentage of a value is defined as the ratio of the value expressed in terms of fraction of 100.
Here,
Percentage of sales tax = 8%
Amount paid as sales tax, P(tax) = 8% of 45.36
P(tax) = 0.08 x 45.36
P(tax) = $3.6288
So, the remaining amount = 45.36 - 3.6288 = $41.7312
Percentage off on the price = 25%
So, the price paid, P' = 0.25 x 41.7312
P' = $10.4328
Therefore,
Original price of the sweater, P = 41.7312 + 10.4328
P = $52.1648
Hence,
The original price of the sweater, in dollars is $52.1648.

A. 120 m²
B. 126 m²
C. 140 m²
D. 156 m²
Answers
Answer:
120m^2
Step-by-step explanation:
Let's start with the bottom. Since the height, base and width are all 4m, we can say that one square = 16 m^2.
There are 5 squares (counting the bottom), and 16 * 5 = 80.
Now the top triangles. We can split the bigger triangle in half. The base is 4m, you can tell from the bottom. To find the area of the triangle, split 4 in half to find the base of the smaller triangles, which equals 2.
Now for the smaller triangles, the base is 2 and the height is 5. We know that to find a triangle's area, you do (b * h)/2, which is (2*5)/2 = 5.
The big triangle is 2 of the small triangles, so you can multiply the smaller triangle's area by 2, which is 5 * 2 = 10.
There are 4 identical triangles at the top-- so 10 * 4 = 40.
80 + 40 = 120.
Hope this helps!
