Answer:

Irrational number

Step-by-step explanation:

<h3>Rational and irrational number:</h3>

Prime factorize the number and then simplify.

$\sf \sqrt{5}*\sqrt{5}*\sqrt{8}=\sqrt{5*5*8}$

$\sf = \sqrt{5*5*2*2*2}\\\ = 5* 2* \sqrt{2}\\\\= 10\sqrt{2}$ is an irrational number.

Find the average distance each data value in the set is from the mean. Round your answer to the nearest tenth, if necessary. Pri

sineoko [7]

Answer:

The average distance of each observation from the mean is 0.

Step-by-step explanation:

We are given the following in the question:

$7, $20, $9, $35, $12, $15, $7, $10, $20, $25

Formula:

$Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}$

$Mean =\displaystyle\frac{160}{10} =16$

Difference from the mean value of each term:

-9, 4, -7, 19, -4, -1, -9, -6, 4, 9

Average distances =

$\text{Average distance} =\displaystyle\frac{0}{10} =0$

Thus, the average distance of each observation from the mean is 0.

Liam has to fill a hole in the ground that is 24 inches deep. He fills the hole at a rate of 6 inches in 30 minutes. Write a fun

kupik [55]

Answer:

The function that models the depth of the hole in feet over time in hours is $h(t) = 24 - 12\cdot t$ .

Step-by-step explanation:

According to the statement, the variable to be modelled is the depth of the hole, which decreases whereas is filled. Under the assumption that the hole is filled at constant rate, we obtain the following expression:

$h(t) = h_{o}-\frac{\Delta h}{\Delta t}\cdot t$ (1)

Where:

$h(t)$ - Current depth of the hole, measured in inches.

$h_{o}$ - Initial depth of the hole, measured in inches.

$\Delta h$ - Filled level, measured in inches.

$\Delta t$ - Filling time, measured in hours.

$t$ - Time, measured in hours.

If we know that $h_{o} = 24\,in$ , $\Delta h = 6\,in$ and $\Delta t = 0.5\,h$ , then the function that models the depth of the hole is:

$h(t) = 24 - 12\cdot t$

The function that models the depth of the hole in feet over time in hours is $h(t) = 24 - 12\cdot t$ .

Which is a good comparison of the estimated sum and the actual sum of 7 7/8 + 2 2/11?

Ipatiy [6.2K]

7 7/8 can be estimated to 8

2 2/11 can be estimated to 2

8 + 2 = 10

7 7/8 = 56+7/8 = 63/8

2 2/11 = 22+2/11 = 24/11

63/8 + 24/11 = 693+192/88 = 10.06

So do you see how similar 10 and 10.06 are to each other? :)

Step-by-step explanation:

48 - 1000g

90 - x

48x = 90000

x = 90000/48

= 1875g = 1.875kg
