Convert the mixed number 7 4/7 to a mixed decimal and round the nearest thousand

RideAnS [48]

Using a calculator, you can find out that $\sf{ \frac{4}{7}\approx 0.571428571 \approx.571$

and so that means $\sf{ 7\frac{4}{7}\approx 7.571428571 \approx 7.571$

so your answer is

$\sf{ 7\frac{4}{7} \approx \huge{\boxed{7.571}}$

If a tree 41.8 feet tall casts a shadow that is 27 feet long, find the height of a tree casting a shadow that is 18.3 feet long

Neko [114]

Answer:

28.3 feet

Step-by-step explanation:

Given a tree 41.8 feet tall casts a shadow that is 27 feet long

So the Tangent of the angle of the sahdow remains the same for the both trees.

We know that $Tanx=\frac{height of the tree}{length of the shadow}$

$\frac{height of the tree1}{length of the shadow1} = \frac{height of the tree2}{length of the shadow2}$

$\frac{41.8}{27} =\frac{x}{18.3}$

$x=\frac{41.8}{27}\times18.3 =28.3$

Therefore the height of the tree is 28.3 feet
