What is the next 2 numbers in the sequence? <br><br> 343,131413,11131114113

VashaNatasha [74]

Answer:

111113111114111113 and 111111131111111411111113

Step-by-step explanation:

Here we want to know the next two numbers in the sequence.

The key here is that we shall be placing the same number of digit 1 between each of the digits 3 4 3

We went from a single 1 to triple, so the next will be 5 digit 1 and the next will be 7 digit 1

So the next number after the third will be;

111113111114111113

The next number after this will be;

111111131111111411111113

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
