Answer: 26 cups will fit in a dispenser that is 30 cm high.

Step-by-step explanation:

First of all, we know that the first cup in the stack (the bottom cup) will be ten centimeters high, and we know that for every cup that is added on top of that, .8 centimeter will be added to the height. So, if we want to find how many cups will be in the dispenser we do this simple math:

30 - 10 = 20 Because the first cup is ten centimeters, we have to subtract that from the dispenser height.

20/.8=25 To find how many cups will be stacked on top of the first cup, we divide the remaining height by .8, the height of every other cup.

Now that we know that there will be 25 cups stacked on top of the first, we add the bottom cup to the rest of them.

25 + 1 = 26 Cups.

Answer: If X = 5, z=<u>-3</u>

If X = 37, z= <u>3.4</u>

Step-by-step explanation:

We know that the formula to find the z-score for any random variable x is given by :-

$z=\dfrac{x-\mu}{\sigma}$

, where $\mu$ = Population mean

$\sigma$ = Population standard deviation.

As per given , we have

$\mu=20\\\\\sigma=5$

Then , the z-score for x =5

$z=\dfrac{5-20}{5}=\dfrac{-15}{5}=-3$

i.e. If X = 5, z=<u>-3</u>

When x =37,then $z=\dfrac{37-20}{5}=\dfrac{17}{5}=3.4$

i.e. If X = 37, z= <u>3.4</u>

You deposited $10,000 into a savings account at 6%. After a certain amount of time, you earned $4,800. How long did you have you

nirvana33 [79]

Answer:

800 months

Step-by-step explanation:

The formula for interest is:

(Capital * saving account * time) / 100

So:

(10000 * 0.06 * x) / (100) = 4800

We clear x:

(10000 * 0.06 * x) = (100) * 4800

x = 480,000 / (10000 * 0.06)

x = 800 months (66.67 years)

Given two points M & N on the coordinate plane, find the slope of MN , and state the slope of the line perpendicular to MN .

telo118 [61]

Answer:

Problem 1) $m = \dfrac{1}{4}$ $slope_{perpendicular} = -4$

Problem 2) $m = \dfrac{1}{3}$ $slope_{perpendicular} = -3$

Step-by-step explanation:

$slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$slope_{perpendicular} = \dfrac{-1}{m}$

Problem 1) M(9,6), N(1,4)

$slope = m = \dfrac{6 - 4}{9 - 1} = \dfrac{2}{8} = \dfrac{1}{4}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{4}} = -4$

Problem 2) M(-2,2), N(4,-4)

$slope = m = \dfrac{4 - 2}{4 - (-2)} = \dfrac{2}{6} = \dfrac{1}{3}$

$slope_{perpendicular} = \dfrac{-1}{\frac{1}{3}} = -3$
