Answer:

They are both proportional.

Tank A = .00375 minutes/gallon

Tank B = 2/600 or ~0.003 minutes/gallon

Step-by-step explanation:

They are both proportional because as time increases, the amount of gallons increases.

Tank A unit rate

Tank B unit rate

Rate = rise / run

Choose points on the graph that has definite points.

Tank A = (1.5 mins - 0.75 mins) / 200 gallons

Tank A = .00375 minutes/gallon

Tank B = (2 mins - 0 mins) / 600 gallons

Tank B = 2/600 or .003 minutes/gallon

How do you think inequalities are different from equations you have worked with before?

dmitriy555 [2]

Answer:

Inequalities are different from equations. If you multiply or divide both sides of an equation by the same negative number, the equation remains the same, but If you multiply or divide both sides of an inequality by the same negative number, the inequality reverses.

HELP ME SOLVE THIS ASAP

vampirchik [111]

Answer:

∠B = 60°

a = 4.0 units

b = 6.9 units

Step-by-step explanation:

The triangle is right angled. The sum of all angles of a triangle is equal to 180 degrees.

The 3 angles are 90, 30 , ∠B .

Thus, B = 180 - 120 = 60 degrees

by trigonometry,

sin(30) = $\frac{a}{8}$ = 0.5

a = (8)(0.5) = 4 units

Also,

cos(30) = $\frac{b}{8}$ = 0.866

b = (8)(0.866)= 6.928
