Answer:
1. C
2.A
3.A
4.B
Step-by-step explanation:
First, lets start by getting all of the perimeters and volumes of the pools. For pool A, it has a volume of 18*9.75*4.5=789.75 cubic feet, and a perimeter of 18*2+9.75*2=55.5 feet. For pool B, it has a volume of 16*10*5=800 cubic feet, and a perimeter of 16*2+10*2=52 feet. For pool C, it has a volume of 15*12*4.5=810 cubic feet, and a perimeter of 15*2+12*2=54 feet. Therefore, for problems 1 and 2, Model C needs the largest amount of water to be filled, while model A needs the least. For problems 3 and 4, Model A uses the largest liner, while Model B uses the smallest one. Hope this helps!
Answer:
z=-7
Step-by-step explanation:
x+y=22(double the average as there are two parts
x+y+z=22 (as shown in the last part)+z=15 (average tripled as there are three parts
22+z=15
z=15-22
z=-7

Answer:
Part 1) 
Part 2) 
Step-by-step explanation:
Part 1) Find the measure of angle a
we know that
The formula to calculate the measure of the interior angle of a regular polygon is equal to
where
n is the number of sides of the regular polygon
For the regular pentagon in the figure
n=5
substitute in the formula
Part 2) Find the measure of angle b
Remember that a regular polygon has equal sides and equal interior angles
so
In the figure , the length of the side of the two smaller equilateral triangles is equal to the length of the side of the regular pentagon
therefore
The triangle in white of the figure is an isosceles triangle
The measure of the vertex angle of the isosceles triangle is equal to
Remember that
The sum of the interior angles of triangle must be equal to 180 degrees
so
solve for b
Answer:
2/3
Step-by-step explanation:
To solve slope: y2- y1/ x2 -x1.
Two points can be (0,6) and (3,8)
8-6/3-0 ---> 2/3
