Explanation:
By definition, the floor is assumed to be level and that means the floor is at a 0 degree angle. The shelf must also have this same angle relative to the floor so we have the shelf and floor as parallel planes. For more info, check out the converse of the corresponding angles theorem.

VOLUME OF RECTANGULAR PRISMS
4 cm
1
7.5 cm
18 cm
Answer: 540 cm³
Step-by-step explanation:
The volume of a rectangular prism can be found with:
V = L * W * H
-> L is the length
-> W is the width
-> H is the height
V = L * W * H
V = 18 cm * 7.5 cm * 4 cm
V = 540 cm³
The volume is 540 cm³.

Volume is 48.2304 solve radius and height Is 6.4 m
If the volume and height of the cylinder are 48.2304 cubic m and 6.4. Then the radius of the cylinder will be 1.55 m.
What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
The volume of the cylinder is 48.2304 cubic m.
And the height of the cylinder is 6.4 m.
Then the radius of the cylinder will be
The volume of the cylinder is given as
Volume = πr²h
48.2304 = π × r² × 6.4

A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 100m long and 62m wide. Find the area of the training field. Use the value 3.14 for π, and do not round your answer. Be sure to include the correct unit in your answer.
The area of a 2D form is the amount of space within its perimeter. The area of the rectangular field is 9,219.07 m².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
At the end of the rectangular field, two semi-circles are used whose diameter is 62 meters, therefore, the radius of the circle is 31 meters(half of the diameter). The area of the semicircle can be written as,
[tex]\text{Area of 2 semicircles} = 2 \times \dfrac{\pi r^2}{2} = \pi r^2[/tex]
Area of 2 semicircles = π(r²) =π × (31²) = 3,019.07 m²
The area of the rectangle is the product of its length and its breadth. Therefore, the area of the rectangle will be,
Area of the rectangle = 100 × 62 =6,200 m²
Now, the area of the rectangular field is the sum of the area of the 2 semi-circles and the rectangle.
Area of the rectangular field= Area of the rectangle + Area of the Semi-circle
Area of the figure= 3,019.07 + 6200 = 9,219.07 m²
Hence, the area of the rectangular field is 9,219.07 m².

Joshua borrowed $2,200 for one year and paid $132 in interest. The bank charged him a service charge of $21. What is the finance charge on this loan?
Joshua borrowed $2,200 for one year and paid $132 in interest. The bank charged him a service charge of $21. The finance charge on this loan is 6.9%.
What is APR?Suppose there is an initial amount as P.
The interest, or say charge on it is applied annually as 'C' amount.
Taking how much percent of P is C, we get:
[tex]APR = \dfrac{C}{P} \times 100[/tex]
Given;
Principal =$2,200
interest = $132
Service charge = $21.
To find finance charge we use
Finance charge (FC) = interest + service charge(SC)
= $132 + $21
= $153
Therefore
APR = Finance charge / Principal
= $153 / $2200
= 0.069 or 6.9%
Therefore, The finance charge on this loan is 6.9%.

A poll is taken at four different grocery stores to determine how far customers drive to shop at their store. The following information was gathered at the four stores. Customers That Drive < 5 miles Store W 52 of 100 Store X 68 of 75 Store Y 59 of 120 Store Z 28 of 50 If one customer is selected at random from each store, at which store would selecting a customer that drives less than 5 miles be a likely event?
Due to the higher proportion of customers driving less than 5 miles, it would be a likely event at store X.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For each store, the proportion of customers driving less than 5 miles is given by:
Store W: 52/100 = 0.52.Store X: 68/75 = 0.9068.Store Y: 59/120 = 0.4917.Store Z: 28/50 = 0.56.Hence, due to the higher proportion of customers driving less than 5 miles, it would be a likely event at store X.
