<h3>Answer: 42.9</h3>

There are two triangles: triangle MAB and triangle MNP

The slanted sides on the right side of the triangles are MB and MP. They correspond to one another. So they form a ratio MB/MP. I have the smaller piece up top. So we'll have the smaller piece of MAB's other known side which is MA = 35.2 (subtract 67.22 and 32) and we'll divide MA over MN = 67.2 making the ratio MA/MN

Solve the proportion for x

MB/MP = MA/MN

x/81.9 = 35.2/67.2

67.2*x = 81.9*35.2 <<--- cross multiply

67.2*x = 2882.88

x = 2882.88/67.2 <<--- divide both sides by 67.2

x = 42.9

Answer:

42.9

Step-by-step explanation:

Remark

When lines are parallel and they are cut by a transversal, their corresponding angles are equal.

  • <MAB = <MNP        Corresponding Angles are equal
  • <MBA = <MPN         Corresponding Angles are equal
  • <M = <M                   Reflexive Property: an angle equals itself
  • These Triangles are similar by AAA

Therefore Corresponding Sides of Similar Triangles are in a ratio

Equation

MA / MN = MB/MP

Givens

  • MA = 67.2 - 32 = 35.2
  • MN = 67.2        
  • MB = x
  • MP - 81.9

Solution

35.2/67.2 = x / 81.9        Cross Multiply

35.2 * 81.9 = 67.2 * x      Combine the left

2883 = 67.2 * x               Divide by 67.2

2883/67.2 = x

x = 42.9                           Answer

Answer:

150m^2

Step-by-step explanation:

Each square on a cube is 5 by 5 meters long.

The area of each square is 5 * 5, which is 25 square meters.

There are 6 sides on a square, so multiply 25 by 6, and you will get 150.

12. A carpenter made two tables. The first table is 4 feet
Arte-miy333 [17]

Answer:

a. True

b. True

c. False

d. False

Step-by-step explanation:

<u>First Table</u>

Length=10 feet, Width=4 feet

Area =10 X 4=40 Square Feet

<u>Second Table</u>

The second table is half as long  as the first table.

Length =0.5 X 10 =5 feet

Area=5 X Width= 5w

The area of the second table is one  fourth the area of the first table.

Area of Second Table =\frac{1}{4} X Area of first table

5w=\frac{1}{4} X 40

5w=10

Width of the Second table, w=2 feet

The following are true.

(a)The width of the second  table is 2 feet.

(b) The area of the second  table is 10 square feet.
