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

answer: idk

step-by-step explanation: sry idk

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10
