Laura is a chemist working with liquids and solutions. She has two large cylindrical barrels that can hold up to 2,000 liters ea

ch. The first barrel contains 900 liters of solution, and the second barrel contains 100 liters of solution. Laura begins draining the first barrel at a rate of 36 liters per minute at the same time she begins filling the second barrel. Laura fills the second barrel with 44 liters of solution every minute. Which inequality represents the seconds, s, when the second barrel contains a greater or equal amount of solution than the first barrel?

Answer:

900 - 0.6s ≤ 100 + 0.73s

Step-by-step explanation:

The left side is the equation for the first barrel containing 900L and draining at 36L/minute. This means that it drains 0.6L/second.

The right side of the equation is for the second barrel containing 100L and filling at 44L/minute. This means that it fills at 0.73L/second.

Liula [17]

Hints on solving trigonometry problems:

If no diagram is given, draw one yourself.

Mark the right angles in the diagram.

Show the sizes of the other angles and the lengths of any lines that are known

Mark the angles or sides you have to calculate.

Consider whether you need to create right triangles by drawing extra lines. For example, divide an isosceles triangle into two congruent right triangles.

Decide whether you will need Pythagorean theorem, sine, cosine or tangent.

Check that your answer is reasonable. The hypotenuse is the longest side in a right triangle.

How to use the tangent ratio to find missing sides or angles?

Which set of values could be from a direct proportion
mr Goodwill [35]

Answer:

First table

Step-by-step explanation:

We have to find the set of value which could be from a direct proportion.

We know that

Direct proportion :

When x is directly proportional to y

x\propto y

x=ky

Where k=Proportionality constant

k=\frac{x}{y}

K remain constant when x and y are in direct proportion

From first table

k=\frac{\frac{1}{2}}{6}=\frac{1}{12}

k=\frac{1}{12}

k=\frac{2}{24}=\frac{1}{12}

K=\frac{3}{36}=\frac{1}{12}

When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.

From second table

k=\frac{0}{0}= not ]define

k=\frac{1}{1}=1

It is not direct proportion because k does not remain constant.

From third table

k=\frac{0}{2}=0

k=\frac{2}{4}=\frac{1}{2}

It is not direct proportion because k does not remain constant.
