The pressure of a certain gas in atmospheres, p, and its For the points in the table, does pressure vary directly
corresponding volume in liters, v, are shown in the table. with volume? If so, identify k and write an equation.
O No, this is not a direct variation.
Yes, this is a direct variation with k
0 Yes, this is a direct variation with k = 1
O Yes, this is a direct variation with k = 3.
Uno

answer: i realy don't get it that much can you me figer it out pleas you

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

ask the math teacher she or he would know lol.

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
