ABCD is a rectangle. if AC = 3y/5 anf BD= 3(y-4), find the length of each diagonal
Digiron [165]
Remember please that Diagonals of a Rectangle are equal to each other:<span> 3y/5 = 3(y-4)
So 
</span><span>3y = 15(y-4)
3y = 15y - 60
60 = 12y
y = 5 Diagonals are both 3 units
With that you will be able to know which is the answer from your options</span>

Mazyrski [523]

Question:

Karina has recently begun kickboxing and purchased training equipment as modeled in the diagram below. The cylindrical base is 15 inches tall with a diameter of 22 inches.

Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).

Answer:

Section = 4847.3205\ in^3

Step-by-step explanation:

Given

h = 15in -- height

d = 22in -- diameter

Required

85% of the volume

First, calculate the radius

r = \frac{1}{2} * d

r = \frac{1}{2} * 22= 11in

The volume (V) is then calculated using:

V = \pi r^2h

V = 3.142* 11^2 * 15

V = 5702.73\ in^3

85% of the volume is:

Section = 85\% * V

Section = 85\% *  5702.73\ in^3

Section = 4847.3205\ in^3

How much fabric is needed to make a tent in the shape of a triangular prism with the following measures?
Contact [7]

Answer:

The fabric needs 196.4 ft²

Step-by-step explanation:

∵ The tent formed formed from 4 faces

  two equilateral triangles with side length 7 ft

  two rectangles with dimensions 11 ft and 7 ft

∵ Area equilateral Δ = 1/4 S²√3

∵ Area rectangle = L × W

∴ The area of the prism = 2 × 1/4 × (7)²√3 + 2 × 7 × 11

                                        = 196.4 ft²

Note:

If you find the area of the triangle by the rule 1/2 × base × height

∴ Area Δ = 1/2 × (7) × 6 = 21 ft²

∴ Area tent = 2 × 21 + 2 × 77 = 196 ft²

Two answer very closed
