A pole that is 3.1 m tall casts a shadow that is 1.16 m long. At the same time, a nearby building casts a shadow that is 46.25 m

Blababa [14]

Answer:

$124\text{ m}$

Explanation:

Here, we want to get the height of the building

Firstly, we need a diagrammatic representation of the presented information

We have that as follows:

The structures and their shadows form right triangles

Right triangles are similar

When two shapes are similar, the ratio of their corresponding sides is equal

Thus, we have it that:

$\begin{gathered} \frac{1.16}{3.1}\text{ = }\frac{46.25}{h} \\ \\ h\text{ = }\frac{46.25\times3.1}{1.16} \\ \\ h\text{ = 123.599 m} \end{gathered}$

To the nearest m, this is 124 m

3.8 times 10 to the power of -8

Yuliya22 [10]

Answer:

1/38^8

Step-by-step explanation:

3.8 times 10 is 38

so it would be 38 to the power of -8 ( 38^-8 )

then you simplify

you have to rewrite the negative power

( you can't have negative power as numerator )

$\frac{38^{-8} }{1}$

so you put it a part of the denominator

which switches the sign

$\frac{1}{38^{8} }$

hope this helps
