At the science fair, Valeria uses 8 fluid ounces of vinegar to make her volcano erupt. How many times can she make her volcano e

BabaBlast [244]

Answer:

Eruption will take place four times

Step-by-step explanation:

Here, we are told that 8 fluid ounce of vinegar made the volcano erupt.

Now we want to know the number of times she can make the volcano erupt using 1 quart of vinegar.

Mathematically, we need to know the number or amount of fluid ounces in 1 quart.

Mathematically;

there are 32 ounces in a quart

So the number of times the volcano eruption will take place using 1 quart vinegar will

be 32/8 = 4 times

Answer:

The perimeter of triangle is 33 meters.

Step-by-step explanation:

Given that the triangle is Equivalent Triangle where all angles and sides are equal, so we can assume that:

7x - 17 = 4x - 5

7x - 4x = 17 - 5

3x = 12

x = 12 ÷ 3

x = 4

OR:

4x - 5 = 2x + 3

4x - 2x = 3 + 5

2x = 8

x = 8 ÷ 2

x = 4

Substitute x = 4 into all expressions:

7x - 17 = 7(4) - 17 = 11 meters

4x - 5 = 4(4) - 5 = 11 meters

2x + 3 = 2(4) + 3 = 11 meters

In order to find out the perimeters, you have to add up all the sides:

P = 11 + 11 + 11

P = 33 meters

Given f of x is equal to the quantity 8x plus 1 end quantity divided by the quantity 2x minus 9 end quantity, what is the end be

boyakko [2]

Answer:

Step-by-step explanation:

Equation

f(x) = (8x + 1) / (2x + 9)

Notice the brackets. They are necessary to show what comes before the division sign, and what comes after.

Behavior

The best way to state the behavior is to get something like a graphing program to show you what the curve looks like -- where it's critical points are for example. I use Desmos for this kind of question, Just do a search for Desmos and bookmark it. You will use it quite often.

So you want to know the behavior.

Right Curve

Crosses the x axis at (-0.125, 0)

Crosses the y axis at (0,0,111)

The right curve has a domain of -∞ < x < ∞

The right curve has a range of -∞ < x < ∞

The range is going to have to go out quite a ways before you see any dramatic decrease in the way it is drawn.

Left Curve.

The right hand curve never crosses either the x or y axis. Nor does it just touch the x or y axis.

The domain is -∞ <x < 0

The range is 0<x<∞
