cSuppose you are standing such that a 45-foot tree is directly between you and the sun. If you are standing 200 feet away from t

beks73 [17]

Answer:

you could stand at 5.0 ft and still be completely in the shadow of the tree

Step-by-step explanation:

From the diagram attached below;

We consider;

$\overline {BC}$ to be the height of the tree and $\overline {DE}$ to be the height of how tall you could be and still be completely in the shadow of the tree.

∠D = ∠B = 90°

Also;

ΔEAD = ΔBAC (similar triangles)

Therefore, their sides will also be proportional

i.e

$\dfrac{\overline {DE}}{ \overline {BC}}= \dfrac{\overline{AD}}{ \overline{AC}}$

$\dfrac{x}{ 45}= \dfrac{225-220}{225}$

$\dfrac{x}{ 45}= \dfrac{25}{225}$

By cross multiply

225x = 45 × 25

$x = \dfrac{45 \times 25}{225}$

$x = \dfrac{1125}{225}$

x = 5.0 ft

Therefore, you could stand at 5.0 ft and still be completely in the shadow of the tree

It was recently estimated that homes without children outnumber homes with children by about seven to five. If there are 2556 ho

nekit [7.7K]

Answer:

929

Step-by-step explanation:

For every 11 children, 7 will have homes and 4 will not.

The fraction of children without homes is 4/11.

The number of children without homes is

4/11 × 2556 = 929

Check:

The number of children with homes is 2556 - 929 = 1627

With/Without = 1627/929 = 7.005/4 ≈ 7/4

OK.
