A recommendation for wheelchair ramps is that the rise-to-run ratio be no greater than 1:12. This ensures that the ramps are nav
patriot [66]

Answer:

a. 12 feet b. 12 feet 0.5 inches c. 8.33 %

Step-by-step explanation:

a. How far out horizontally on the ground will it protrude from the building?

Since the rise to run ratio is 1:12 and the building is 12 inches off the ground, let x be the horizontal distance the ramp protrudes.

So, by ratios rise/run = 1/12 = 12/x

1/12 = 12/x

x = 12 × 12

x = 144 inches

Since 12 inches = 1 foot, 144 inches = 144 × 1 inch = 144 × 1 foot/12 inches = 12 feet

b. How long should the ramp be?

The length of the ramp, L is gotten from Pythagoras' theorem since the ramp is a right-angled triangle with sides 12 inches and 144 inches respectively.

So, L = √(12² + 144²)

= √[12² + (12² × 12²)]

= 12√(1 + 144)

= 12√145

= 12 × 12.042

= 144.5 inches

Since 12 inches = 1 foot, 144.5 inches = 144 × 1 inch + 0.5 inches = 144 × 1 foot/12 inches + 0.5 inches = 12 feet 0.5 inches

c. What percent grade is the ramp?

The percentage grade of the ramp = rise/run × 100 %

= 12 inches/144 inches × 100 %

= 1/12 × 100 %

= 0.0833 × 100 %

= 8.33 %

forsale [732]

Answer:

  • n < 18
  • n ≥ 15

Step-by-step explanation:

The wording "fewer than" is translated to the math symbol "less than". The variable n represents the number of students.

  <em>the number of students</em> is fewer than 18

translates to ...

  n < 18

__

The wording "at least" translates to the math symbol "greater than or equal to."

  <em>the number of students</em> is at least 15

translates to ...

  n ≥ 15

Anit [1.1K]

Hey!


1 car is $3.83.

3 cars is $3.83 × 3


3.83 × 3 = 11.49


Shipping fee is $4.55. Add that to the price of the 3 cars


11.49 + 4.55 = 16.04


The girls share the cost equally. Divide by 2


16.04 ÷ 2 = 8.02


\framebox{Each girl pays \$8.02}
