Its C! Lets say x=30
|30-323|=50
This could technically be true because it would show if the temp is within range

<h2>Answer:</h2>

The equation which can be used to determine the minimum and maximum temperatures between which water is a liquid is:

C.) |x – 323| = 50

<h2>Step-by-step explanation:</h2>

It is given that:

For water to be a liquid, its temperature must be within 50 Kelvin of 323 Kelvin.

This means that the ideal temperature is: 323 Kelvin.

This means that the temperature could maximum decrease by 50 kelvin and it could maximum increase by 50 kelvin with respect to 323 kelvin.

Hence, the equation will be:

|x – 323| = 50

such that the maximum temperature is:

x-323=50

i.e. x=323+50

i.e. x=373 kelvin

and the minimum temperature is:

x-323= -50

i.e.

x=323-50

i.e. x=273 kelvin.

Solve |p + 2| = 10Solve |p + 2| = 10<br><br> {-12}<br> {-8, 8}<br> {-12, 8}

By definition, we have

$|p+2| = \begin{cases} p+2 &\text{ if } p+2 \geq 0 \\-p-2 &\text{ if } p+2 < 0 \end{cases}$

So, we have to solve two different equations, depending of the possible range for the variable. We have to remember about these ranges when we decide to accept or discard the solutions:

Suppose that $p+2\geq 0 \iff p \geq -2$

In this case, the absolute value doesn't do anything: the equation is

$p+2 = 10 \iff p = 10-2 = 8$

We are supposing $p \geq -2$ , so we can accept this solution.

Now, suppose that $p+2 < 0 \iff p < -2$ . Now the sign of the expression is flipped by the absolute value, and the equation becomes

$-p-2 = 10 \iff -p = 12 \iff p = -12$

Again, the solution is coherent with the assumption, so we can accept this value as well.

If a student didn’t understand proportional relationships, how would you explain it to them?

kirill [66]

Answer:

Proportional relationships are relationships between two variables where their ratios are equivalent.

Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

I really recommend watching Khan Academy's video over proportional relationships, the speaker explains it very well!!

Can someone plz help me with this and i need the drawing to show work

Burka [1]

Answer:

20.833 feet

Step-by-step explanation:

The light reflects off the mirror at the same angle that it hits it at. So the triangle formed by the beam and mirror is similar to the triangle formed by Kevin and the mirror.

Therefore, we can write and solve a proportion.

h / 10 = 6.25 / 3

h = 20.833

The beam is 20.833 feet tall.
