A glass of water was seven- eighths of a liter. With a 6 liter jug, how many glasses could you pour? Do you have to multiply div
ivolga24 [154]

Let us suppose, we pour x glass of water.

The given jug is of 6 liters. And the glass of water was seven- eighths of a liter. Hence, we have the below equation

\frac{7}{8} x= 6

Now, in order to solve for x, we will divide 6 with 7/8. So, we have to divide.

x=\frac{6}{7/8} \\
\\
x=\frac{48}{7} \\
\\
x=6.9

Hence, we can pour 7 glass of water. But the 7th glass is not full of water. It is partially full.

Which of the following is equivalent to (x^4/3 x^2/3)^1/3
Reika [66]

Answer:

The answer is2nd point

Step-by-step explanation:

{n}^{a}  \times  {n}^{b}  =  {n}^{a + b}

(x^4/3)×(x^2/3) = x^(4/3 + 2/3)

= x²

{( {n}^{a} )}^{b}  =  {n}^{ab}

(x²)^1/3 = x^(2×1/3)

= x^2/3

What is an equation of the line that is perpendicular to y=−23x+5 and passes through the point (2, 11) ?
hichkok12 [17]

Answer:

The equation would be y = 1/23x - 251/23

Step-by-step explanation:

To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -23. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 1/23.

Now that we have this, we can use the point and the slope in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 11 = 1/23(x - 2)

y - 11 = 1/23x - 2/23

y = 1/23x - 251/23

When graphing a linear inequality in two variables, explain how to determine which side of the boundary line to shade. Please he
Murrr4er [49]
\ \textgreater \ means you shade the part above the line, and \ \textless \ means you shade the part under the line.

If it has an equal bar under it, like this: \leq  or \geq, then you also shade the line, by making it solid instead of dotting it.

If john makes a contribution to a charity fund at school, the average contribution size will increase by 50% reaching $75 per pe
Sonja [21]

Answer:

Z= 75*6 -250=200

So then the correct answer is B. $200.

Step-by-step explanation:

Notation

Let X be the average contribution size before John makes his contribution.

Let Y be the total contribution size before John makes his contribution.

Let Z be John's contribution.

We know that for this case $ 75 represent the original average amount before the contribution with 50% increase so we can set up the following equation in order to find the original average amount

1.5 X = 75

And solvong for X we got:

X = \frac{75}{1.5}= 50

Now we can find the total contribution before the donation with the following proportion:

\frac{50}{1}= \frac{Y}{5}

Y = 250

And then with the formula of average taking in count the 6 values we can find the size of donation Z like this:

\frac{Y+Z}{6}= 75

\frac{250+Z}{6}= 75

Z= 75*6 -250=200

So then the correct answer is B. $200.
