find out the bottom which is a rectangle so 30x15=450
find out the triangle in the middle and back so you work out half of the whole rectangle so 15x8=120x2=240
and work out the triangles above so 15x17=255x2=510
add up 510+240+450=1200
Answer: 1200

Which equation represents the cost of a phone call, c, in cents, after m minutes, according to the payment plan?
A. c=1/6m
B. c=6m
C. c=1/30m
D. c=30m
Answers
Answer:
B
Step-by-step explanation:
Slope equals rise over run so the slope of this line is 30/5 or 6. That means for every minute calling you would have to pay 6 cents which is shown in the equation c=6m.
the slope of the line represents the rate of the plan and can be calculated by using the change in y values divided by the change in x values of two points on the line. In this case, it would be easiest to pick 0 and 6 as y values, and 0 and 1 as x values. then,
slope = (6-0) / (1-0)
slope = 6/1
slope = 6
therefore the slope is 6 and the correct equation is B: c=6m
In the figure below, DOG, ION, and IDO are congruent and isosceles, each with perimeter 55. The quadrilaterals FLIN, DIES, and DRAG are all squares. The perimeter of the 11-sided polygon DRAGONFLIES is 127.
What is the area of DRAG?
Answers
Let's call the sides that are length DG " s " .
And let's call the sides that are length GO " t ".
Since the perimeter of each triangle is 55...
s + t + t = 55
s + 2t = 55
2t = 55 - s
Since the perimeter of the entire figure is 127...
9s + 2t = 127
Since 2t = 55 - s , we can replace 2t with 55 - s .
9s + (55 - s) = 127
8s + 55 = 127 Subtract 55 from both sides.
8s = 72 Divide both sides by 8 .
s = 9
And...the area of the square DRAG = DG2 = s2 = 92 = 81 sq. units.

The Smith family has a circular shaped pool with a radius of 10 feet. What is the minimum amount of material needed to make a cover for the surface of the pool?
62.8 sq. feet
314 sq. feet
31.4 sq. feet
100 sq. feet
Answers
Answer:
314 sq. feet
Step-by-step explanation:
The surface area of the pool would be the area in math. The equation for solving the area of a circle goes as follows:
A=πr^2
π·10^2
314
Answer:
A
Step-by-step explanation:
A circular shaped pool.
The radius is 10 feet.
We need to find the surface area to make a cover for the pool.
We can use the formula for the area of a circle:
A = [tex]\pi[/tex]r²
A = (3.14)(10)(2)
A = (31.4)(2)
A = 62.8
The minimum amount of material needed to make a cover is 62.8 square feet.
