When his elevation is higher than 1600meters, breathing is difficult for matt. write an inequality that describes h, the elevation at which breathing is difficult for matt

The elevation at which it gets difficult for Matt to breath is higher than 1600 meters.

Which means Matt should stay below the height of 1600 meters. Now the height should be less than 1600 meters for Matt.

As we stated above that 'h' (height) should be less than 1600 meters, that means:

Therefore, the inequality to represent the height (h) less than 1600 meters is .

the correct answer is 828.07

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
