A rectangular parking lot is 75 feet wide and 150 feet long. The owner wants to increase the width by 100 feet. What is the appr
Trava [24]

The <em>approximate increase</em> in Area of the parking lot is about 133%

Area of a rectangle = Length × width

<u>Initial Area of parking lot</u> :

  • 75 feets × 150 feets = 11250 ft²

<u>New Area of parking lot</u> :

Width = 75 + 100 = 175 feets

Length = 150 feets

Area = 175 × 150 = 26250 ft²

<u>Percentage increase in </u><u>Area</u><u> </u><u>of lot</u> :

((16250 - 11250) / initial Area) × 100%

(15000 / 11250) × 100% = 133.33%

Therefore, the <em>approximate increase</em> on area of lot is 133%

yKpoI14uk [10]

The distance from the satellite to the Earth's horizon is 6398 km

<h3>Pythagoras theorem</h3>

Pythagoras theorem is used to show the relationship between the sides of a right angled triangle. It is given by:

Hypotenuse side² = Adjacent side² + Opposite side²

Let x represent the distance from the satellite to the Earth's horizon

Hence:

  • x² = 6370² + 600²
  • x² = 40936900
  • x = 6398 km

The distance from the satellite to the Earth's horizon is 6398 km

Bumek [7]

Answer:   6\dfrac{3}{8}\text{ inches}

Step-by-step explanation:

Given: Original length = 15\dfrac{1}{8} inches

=\dfrac{8\times15+1}{8}=\dfrac{121}{8} inches                      ( In improper fraction )

Length of piece cut from original = 8\dfrac{3}{4} inches

=\dfrac{4\times8+3}{4}= \dfrac{35}{4} inches                 ( In improper fraction )

Length of piece leftover piece =  (Original length ) - (Length of piece cut )

=\dfrac{121}{8}-\dfrac{35}{4}\\\\=\dfrac{121-2\times35}{8}\\\\=\dfrac{121-70}{8}\\\\=\dfrac{51}{8}\\\\=6\dfrac{3}{8}\text{ inches}

Hence, the leftover piece will be 6\dfrac{3}{8}\text{ inches}  long.
