232 bc 15500 divided by 100 is 155 then 155 times 232 is 32860

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.
