I’m going to attach a photo because that’s the only way I can explain it.
First, draw out the image that they are describing with triangles to help solve the problem. Then you will see a relationship between the sides. The length of the shadows from the person to the tree’s multiplies by 5. So we can multiply the persons height by 5 as well since they are similar.

$f-354=1221$ add 354 to both sides

$f+354-354=1221+354\\\\\boxed{f=1,575}\to\boxed{D.}$

Andy has three planks of wood. Two planks are each 1.5 m long. One plank is 2.5m long. What is the total length of all the three

11Alexandr11 [23.1K]

Given:

Two planks are each 1.5 m long.

One plank is 2.5m long.

To find:

The total length of all the three planks.

Solution:

Two planks are each 1.5 m long. So,

First plank = 1.5 m

Second plank = 1.5 m

One plank is 2.5m long. So,

Third plank = 2.5 m

Now, the total length of all the three planks is

$\text{Total length}=\text{First plank + Second plank + Third plank}$

$\text{Total length}=1.5+1.5+2.5$

$\text{Total length}=5.5$

Therefore, the total length of all the three planks is 5.5 m.

What are the solution(s) of x2-4-0? X= 4 or X=4 X=-2 or x= 2 x=2 x=4

Pavel [41]

Answer:

Step-by-step explanation:

First you add 4 on both sides

X^2=0

Then you take square on both sides

X=+- the square root of 4

Simplify that

X=plus or minus 2

The answer can be either -2 or +2 (which is just 2)

Solve. Round to the nearest hundredth. 29.3 = 1.7y

Elena-2011 [213]

Steps to Solve:

29.3 = 1.7y

29.3/1.7 = 1.7y/1.7

y = 17.2352941176

In this case, we round up the hundredths place because the number in the thousandths place is 5 or higher.

y = 17.24

Hope this helps!! :)
