What is the slant height of a pyramid with a 864 square inch surface area and a 18 inch square base
seropon [69]
To determine the slant height, you will use what you know about surface area of a pyramid.

The surface area of a square Peerman consists of one square, and four congruent triangles.

We know the length of one side on the square base is 18 inches.

The area of the base then would be 324 in.².

Subtract this from the total surface area.

864-324 = 540 in.²

Divide 540 in.² by 4 because there are four congruent triangles.

540/4= 135 in.²

Each triangle is 135 in.². Now use the formula for area of a triangle to solve for the missing slant height.

A = 1/2 x b x h
135 = 1/2 x 18 x h
135 = 9h
h = 15 inches.

The slant height is 15 inches.

Solve for perimeter and area of rectangle
agasfer [191]
U would find the distance between the each point, though since the rectangle has two pairs of congruent sides you only need to solve for two and add/multiply accordingly using p = 2l + 2w and a = lw . my phones a little broken so I can’t see the pic/solve exactly but u could use the distance formula to find the lengths of the lines. hope this helped

Miguel conducts a survey of 750 college students to see how many of them have a part-time job. His results show that 500 of the
Bingel [31]
Miguel: 500 out of 750 students have part time jobs.

500 ÷ 250 = 2
750 ÷ 250 = 3

500:750 = 2:3


A) 200 out of 300 ⇒ 200/100 and 300/100 ⇒ 2:3
B) 700 out of 1100 ⇒ 700/100 and 1100/100 ⇒ 7:11
C) 800 out of 1200 ⇒ 800/400 and 1200/400 ⇒ 2:3
D) 9000 out of 1300 ⇒ 9000/100 and 1300/100 ⇒ 90:13

Among the choices, Choice B could represent Kureshi's Data because it is not proportional to the data of Miguel.

Choice D is not possible. You cannot have a result that is way beyond the scope of your population. It is impossible to get 9000 students out of only 1300 students.
