Answer:

46

Step-by-step explanation:

Break the shape into smaller shapes, then solve:

Large Rectangle -> 4x8=32

Tiny Rectangle at the bottom ->2x3=6

Triangle at top can be broken into two right triangles ->

(4x2)(1/2)=4

(4x2)(1/2)=4

Add: 32+6+4+4=46

The length of one side of a triangle is 2 feet less than three times the length of its second side. The length of the third side
seropon [69]

Answer:

  • 7 feet, 3 feet, 7.5 feet

Step-by-step explanation:

Let the sides be a, b and c.

<h3>Given</h3>

The length of one side of a triangle is 2 feet less than three times the length of its second side

  • a = 3b - 2

The length of the third side is 3/4 of the sum of the lengths of the first two sides:

  • c = (3/4)(a + b)

The perimeter of the triangle is 17.5 feet:

  • a + b + c = 17.5

<h3>Solution</h3>

Substitute a with b in the second equation:

  • c = (3/4)(3b - 2 + b) = (3/4)(4b - 2) = (3/4)(4b) - (3/4)(2) = 3b - 1.5

Now substitute a and c with b in the third equation and solve for b:

  • a + b + c = 17.5
  • 3b - 2 + b + 3b - 1.5 = 17.5
  • 7b - 3.5 = 17.5
  • 7b = 17.5 + 3.5
  • 7b = 21
  • b = 3

Find the value of a:

  • a = 3b - 2 = 3*3 - 2 = 9 - 2 = 7

Find the value of c:

  • c = 3b - 1.5 = 3*3 - 1.5 = 9 - 1.5 = 7.5

The sides of the triangle are:

  • a = 7 feet, b = 3 feet, c = 7.5 feet

2+3w&lt;-1&lt;3w+5<br><br><br><br><br><br>Answer please
Dafna1 [17]

2 + 3w < -1 < 3w + 5       |subtract 3w from all sides

2 < -1 - 3w < 5       |add 1 to all sides

3 < -3w < 6        |change the signs

-3 > 3w > -6      |divide both sides by 3

-1 > w > -2 → -2 < w < -1 → w ∈ (-2, -1)

A map of a town has no scale. You know that the distance between the bus stop and the park is 6 miles. On the map it is 3 inches
slamgirl [31]

As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.

 

16 miles   =   x miles

(1/2) inch      2 3/4 inches

 

x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles

      (1/2)
