You are 5 feet tall and cast an 8-foot shadow. A lamppost nearby casts a shadow that is 20 feet. Which equation can you use to solve for the height (h) of

Answers

Answer:

Height of lamppost would is 12.5 feet.

Step-by-step explanation:

We are given a 5 feet tall boy form shadow with 8 foot.

As we know height is directly proportional to shadow length.

\therefore h\propto s

h=ks

where, h is height of boy, k is constant of proportionality and s is shadow length.

when h=5 , s=8

5=8k

k=(5)/(8)

We need to find height when shadow length is 20 feet.

h=(5)/(8)* 20\Rightarrow 12.5\text{ foot}

Thus, Height of lamppost would be 12.5 feet.
5 : 8 = x : 20
20*5 = 8x
x = 12,5
Therefore height of the lamp is 12.5 feet :)

Draw the shape by drawing dots at the co-ordinates. 
Connect them in order, so if it's KLMN, connect K to L then to M then N.
Then, pick one of the points, I'd choose K, then move that dot 3 to the right, then move it 4 up. Do the same for all of the letters.

Why is 9 -1is 8 can some one help me because i dont understand why is not 10

Answers

Ah, the dash, this thing, - means subtraction, which is the opposite of addition, and takes away numbers. Meaning 9-1 is 9, but you count down by 1 rather than up one.
Its 8 because your not adding your subtracting.
