Answer:

4.64 + 10^2

Answer:

$166\frac{2}{3}\ m$

Step-by-step explanation:

Let

x ----> the average depth of the resulting layers of ash and rock

we know that

To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.

$\frac{100\ km^3}{600\ km^2}=\frac{1}{6}\ km$

Convert to meters

Remember that

$1\ km=1,000\ m$

$\frac{1}{6}\ km=\frac{1}{6}(1,000)=\frac{1,000}{6}=\frac{500}{3}\ m$

Convert to mixed number

$\frac{500}{3}\ m=\frac{498}{3}+\frac{2}{3}=166\frac{2}{3}\ m$

Answer:

$\frac{x - 3}{x + 4} \div \frac{x ^{2} - 1 }{ x} \\ = \frac{x - 3}{x + 4} \times \frac{x}{ {x}^{2} - 1} \\ =\frac{x(x - 3)}{(x + 4)( {x}^{2} - 1) } \\= \frac{x(x - 3)}{(x + 4)(x + 1)(x - 1)}$

Regular quadrilateral pyramid with base edge b=55 mm and lateral edge l = 7cm. Find the sum of all edges

egoroff_w [7]

Answer:

50cm or 500mm

Step-by-step explanation:

There are 4 base edges and 4 lateral edges, therefore, multiply the number for both edges by 4 and add.

Considering the fact that we were given two units of measurement, millimeters and centimeters, but we know that there are 10mm (millimeters) in a cm (centimeter) , we can just divide 55 by 10 to get 5.5.

Therefore;

5.5 x 4 = 22

7 x 4 = 28

28 + 22 = 50cm
