How do u set up the word problem

Mathematics
1 answer:
galina1969 [7]3 years ago

Answer:

8 feet

Step-by-step explanation:

First, draw a picture.  The pole is 22 feet tall.  Katherine is 5.5 feet tall.  She is 24 feet from the pole.  The light from the top of the pole to the tip of her shadow forms two similar right triangles.  The length of her shadow is x.

Now use similar triangles to write a proportion:

22 / (24 + x) = 5.5 / x

Cross multiply:

22x = 5.5 (24 + x)

Distribute:

22x = 132 + 5.5x

Combine like terms:

16.5x = 132

Divide:

x = 8

The shadow is 8 feet long.

I have a 3 foot board that needs to be equally decided into 1/2 how many extra peices will I have
anygoal [31]

Answer:

No extra pieces.

Step-by-step explanation:

Given:

Total number of foot board = 3

Equally divided into =  1/2

Question asked:

How many extra pieces will I have = ?

Solution:

By dividing 3 by 1/2 we can find the extra pieces.

                                                                 = 3\div\frac{1}{2}

                                                                 = 3\times\frac{2}{1}

                                                                 = 6

Since, the remainder is zero, thus there is no any extra pieces I have.

Thankyou for all the help
Travka [436]

Answer:

1. x + y = 180

2. x = 50 y= 130

Step-by-step explanation:

They're parallel.

We can label the unamed angle z.

So z = y

and 50 = x

There's 360 degrees in a circle, so x + y= 180 because it's half 360 and half a circle.

x=50

so 50 + 50 = 100.

360 - 100 = 260

so 260 ÷ 2 = 130

y = 130 because y and z are equal so they're the same number
