Current law requires that wheelchair ramps have a height to length ratio of 1: 12. an old ramp has a height to length ratio of 2: 15. it's height is 12 inches. workers will replace this ramp with a new one that has the same height. how much longer must the new ramp be to meet the ramp ratio required by law? !

The new ramp must be 54 inches long than the old ramp to meet the requirement of the new law

Step-by-step explanation:

Old height to length ratio is:

h : l =  2 : 15.

Height of old ramp h = 12

Length of old ramp can be find out by putting h  = 12 in the above ratio

Length of old ramp = 90

Height to length ratio by current law:

h : l = 1 : 12

Height will be the same i.e. h = 12

Length of new ramp = 144

How much longer the new ramp should be to meet the new ratio law:

New length - Old length = 144 - 90 = 54 inches

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

find the vertical and horizontal asymptotes of the function f x = 5 x − 1 . to find the vertical asymptote, equate the denominator to zero and solve for . since the degree of the polynomial in the numerator is less than that of the denominator, the horizontal asymptote is .
