Answer:
13.4feet
Step-by-step explanation:
The set up forms a right triangle.
Given
Height of the staircase h = 12 feet
Base of the stairs b = 6feet
Required
Length of the ramp l
Using the pythagoras theorem
l² = h² + b²
l² = 12²+6²
l² = 144 + 36
l² = 180
l = √180
l = 13.42 feet
Hence the length of the ramp to the nearest tenth is 13.4feet
Answer:
if you want to sketch the trapezoid you will also need other dimensions like height and the length of the parallel sides

Explanation:
______________________________________________
There are 20 nickels in one dollar.
Since 1 dollar = $1.00 = 100 cents ; and:
1 nickel = 5 cents
________________________________________________
(5 cents)*x = 100 cents ; solve for "x" ; x = the number of nickels in 1 dollar;
Divide each side of the equation by "5 cents" ;
[(5 cents)*x] / (5 cents) = (100 cents) / (5 cents) ;
to get:
_____________________________________________
x = 20 .
_____________________________________________
There are 20 nickels in one (1) dollar.
20 nickels * 17 dollars = number of nickels in 17 dollars.
___________________________________________________
20 * 17 = 340 nickels in 17 dollars.

The answer is: " 340 " . There are 340 nickels in 17 dollars.
