What is the perimeter of triangle ABC?
julia-pushkina [17]

Answer:

18 units

Step-by-step explanation:

Using the midpoint theorem, the perimeter of the triangle formed by joining the midpoints of the original triangle is exactly half the size in perimeter

What we mean in this case is that the perimeter of BAC IS two times the perimeter of EDF

perimeter of EDF is the sum of all the sides = 2 + 4 + 3 = 9

So the perimeter of BAC is 2 * 9 = 18

a landscaper has 125 tiles it has to be a square patio , the patio has to have at least an area of 80 square feet what are the p
Marat540 [252]
Area of a square is given by multiplying the length by the width, but since a square has four sides of equal length, we will end up multiplying two numbers that are the same.

We want a minimum area of 80 square feet and at the maximum of 125 square feet

Think of the square numbers that are in between 80 and 125

8 × 8 = 64
9 × 9 = 81
10 × 10 = 100
11 × 11 = 121
12 × 12 = 144

There are three possible measurements of the patio:

9 by 9 and number of tiles left = 125 - 81 = 44 tiles
10 by 10 and number of tiles left = 125 - 100 = 25 tiles
11 by 11 and number of tiles left = 125 - 121 = 4 tiles

The area of a mattress is 56 square feet. The width of the bed is x+4 and the length is 8. Solve for the value of
Molodets [167]

The width of the mattress is 7.

Give that

  • The area of the mattress is 56 square feet.
  • The length is 8.
  • And, the width of the bed is x + 4.

Now as we know that

Area of the rectangle = Length × width

56 square feet = 8 × (x + 4)

56 = 8x + 32

56 - 32 = 8x

x = 3

So, the width is

= 3 + 4

= 7

Therefore we can conclude that the the width of the mattress is 7.
