A lot is in the shape of a trapezoid. The sum of the bases is 180 feet. If the area of the lot is 8100 square feet, what is the

distance across the lot, i.e., the altitude of the figure?

Answer: The altitude is 90.

Step-by-step explanation: the formula to calculate a trapezoid: A = (.5)(B+b)h.

plug the values in.

8100 = (.5)(180)h

8100 = 90h

h = 8100/90

h = 90

Y = 4x - 3<br>y= 2x + 13

Serggg [28]

Answer:

x = 9, y = 29 or (8,29)

Step-by-step explanation:

Set the equations equal to each other because they both equal y:

4x - 3 = 2x + 13

Combine like terms:

2x = 16

Divide by 2:

x = 8

Plug 8 into the x for both equations and see if the y is the same:

y = 4(8) - 3 = 32 - 3 = 29

y = 2(8) + 13 = 16 + 13 = 29

Select the choice which shows all of the diagonals in this polygon and tells how many there are.

Leona [35]

Answer:

Answer C

Step-by-step explanation:

If the polygon has n sides, then the number of diagonals the polygon has is

(n - 3)*n/2

So for a seven sided figure the number of diagonals would be

(7 - 3)(7)/2 = 4*7/2 = 28/2 = 14

A cone has a diameter of 6 cm and a height that is 3 times the diameter. Using 3.14 for pi, which of the following can be used t

Zinaida [17]

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Step-by-step explanation:

Given

Diameter of Cone = d = 6 cm

Radius will be:

r = d/2 = 6/2 = 3 cm

Height of cone = h = 3d = 18 cm

The volume of cone is given by:

$V = \frac{1}{3}\pi r^2h$

Putting the values

$V = \frac{1}{3} (3.14)(3)^2(18)$

Hence,

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer
