Answer:

Calculating percentages are important as they apply to real life activities. For example, shopping. If you are on a budget and you want to know how much your total is with tax, you can convert the decimal for the tax, turn it into a percent and add it to your total. Another example is eating at a restaurant. A good tip is 15-20% so you can calculate this and add it to your price.

The perimeter of a rectangular concrete slab is 106 feet and its area is 570 square feet. What is the length of the longer
Sliva [168]

Answer:

The length of the long side of the rectangle is 38 ft.

Step-by-step explanation:

If we test out all possible factors, we will see that 15 x 38 is the most fitting.  

Perimeter: 15 + 15 + 38 + 38 = 106 ft.

Area: 15 x 38 = 570 square ft.

38 ft. is the measurement of the long side and 15 ft. is the measurement of the smaller side.

The perimeter of a rectangle is equal to 163 yard. The width is 8 more than twice the length. Find the length and width.​
Sedaia [141]

Answer:

l = 29.4 yards

w = 66.8 yards

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Perimeter of a Rectangle: P = 2w + 2l

Step-by-step explanation:

<u>Step 1: Define</u>

P = 163 yards

w = 2l + 8

l = l

<u>Step 2: Set up equation</u>

P = 2w + 2l

163 = 2(2l + 8) + l

<u>Step 3: Solve for </u><em><u>l</u></em>

  1. Distribute 2:                              163 = 4l + 16 + l
  2. Combine like terms:                 163 = 5l + 16
  3. Subtract 16 on both sides:        147 = 5l
  4. Divide both sides by 5:             147/5 = l
  5. Rewrite:                                      l = 147/5
  6. Evaluate:                                    l = 29.4 yards

<u>Step 4: Find </u><em><u>w</u></em>

  1. Define:                    w = 2l + 8
  2. Substitute:              w = 2(29.4) + 8
  3. Multiply:                  w = 58.8 + 8
  4. Add:                        w = 66.8 yards
