shtirl [24]

Given:

$\dfrac{2}{10}$ divded by $\dfrac{2}{4}$ .

To find:

The solution for the given division problem.

Solution:

We have, $\dfrac{2}{10}$ divded by $\dfrac{2}{4}$ . It can be written as

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{10}\times \dfrac{4}{2}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2\times 4}{10\times 2}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{8}{20}$

$\dfrac{2}{10}\div \dfrac{2}{4}=\dfrac{2}{5}$

Therefore, the solution for the given division problem is $\dfrac{2}{5}$ .

natulia [17]

Answer:

114.31 nautical miles per day

Step-by-step explanation:

Use formula

$S=v\cdot t,$

where S is the distance, t is time and v is rate.

If S=11431 nautical miles and t=100 days, then

$v=\dfrac{11431}{100}=114.31\ \text{nautical miles per day}.$

Find the area bounded by the graphs of the indicated equations over the given interval.

NeX [460]

Answer:

Step-by-step explanation:

$y = 0$

is basically the horizontal axis.

First, find the integral of x^2-25.

Remember that

integral of a constant is that constant times x.

Also that

to take the integral of a power function, add 1 to the degree and divide by that same degree.

$y = {x}^{2} - 25$

We then get

$\frac{ {x}^{3} }{3} - 25x$

Evaluate at -3

$\frac{ - 3 {}^{3} }{3} - 25( - 3)$

$- 27 + 75 = 48$

Then we evaluate at 0

$\frac{0 {}^{3} }{3} - 25(0) = 0$

Next, we subtract the the answer then we get

$48 - 0 = 48$
