Juanita and Samuel are planning a pizza party. They order a rectangle sheet pizza that measures 21 inches by 36 inches.?They tel
saveliy_v [14]
First, find the total area of pizza. The area of a rectangle is length times width. 

Area = 21 x 36 = 756 sq. inches

Now, we must divide the total area with the largest square possible without any excess. So, we equate the area of the pizza to area of square:

A = s² = 756
s = 6 √21

Hence, the largest piece square possible has a side of 6 inches. Then, we divide the total area of the pizza by the area of each square piece to find the number of pieces;

756/6² = 21

Thus, there would be 21 pieces of 6-in square piece of pizza.

Lana71 [14]

Answer:


Step-by-step explanation:

A) Use the slope formula to find the slope  m.


m=4/13


B)  Use the point-slope formula,  y−y1=m(x−x1)  to find the equation of the line.


y=4/13x+198/13


C) Write in slope-intercept form,  y=mx+b.


y=4/13x+198/13

What is the common difference between the elements of the arithmetic sequence below? –18, –22.5, –27, –31.5, –36
klasskru [66]
<span><u>Answer </u>
Common difference = -4.5

<u>Explanation. </u>
An arithmetic sequence is a sequence in which the next term is found by adding a constant to the current term. This constant is called the common difference.
If a, b, c, d, e, ….is an arithmetic sequence, then the common difference will be,
Common difference = b-a=c-b=d-c=e-d…..
Now the question above common difference is;
Common difference = (-22.5)-(-14)=-4.5
