I need help pls step by step i will really appreciate pls also l will mark you the brainly if you did !

agasfer [191]

Answer:

1. 2

2.3 $\sqrt{5}$

3.8 $\sqrt{6}$

4.2.5 $\sqrt{10}$

Step-by-step explanation:

Remember that $\frac{\sqrt{a}}{\sqrt{b}}$ = $\sqrt{\frac{a}{b} }$ , and $\frac{a}{\sqrt{b}}$ = $\frac{a}{\sqrt{b}}$ * $\frac{\sqrt{b}}{\sqrt{b}}$ = $\frac{a\sqrt{b}}{b}$

1. $\frac{\sqrt{48}}{\sqrt{12} }$ = $\sqrt{\frac{48}{12} }$ = $\sqrt{4}$ =2

2. $\frac{15}{\sqrt{5} }$ = $\frac{15}{\sqrt{5} }$ * $\frac{\sqrt{5}}{\sqrt{5} }$ = $\frac{15\sqrt{5} }{5}}$ =3 $\sqrt{5}$

3. $\frac{48}{\sqrt{6}}$ = $\frac{48}{\sqrt{6}}$ * $\frac{\sqrt{6}}{\sqrt{6}}$ = $\frac{48\sqrt{6}}{6}$ =8 $\sqrt{6}$

4. $\frac{25}{\sqrt{10}}$ = $\frac{25}{\sqrt{10}}$ * $\frac{\sqrt{10}}{\sqrt{10}}$ = $\frac{25\sqrt{10}}{10}$ =2.5 $\sqrt{10}$

A sculpture is created with colored blocks each with a volume of 1 cubic foot. What is its volume if the sculpture is 12 feet lo

padilas [110]

Answer:

480 ft^3

Step-by-step explanation:

We can calculate the volume of the sculpture with the data they give us in the statement.

The volume would be the multiplication between the length, width and height, that is:

v = l * w * h

we know that l = 12 ft; w = 5 ft; h = 8 f, replacing:

v = 12 * 5 * 8

v = 480

in other words, the volume of the sculpture is 480 cubic feet, therefore 480 color blocks are needed because its volume is 1 cubic foot.
