If a tree 41.8 feet tall casts a shadow that is 27 feet long, find the height of a tree casting a shadow that is 18.3 feet long
Neko [114]

Answer:

28.3 feet

Step-by-step explanation:

Given a tree 41.8 feet tall casts a shadow that is 27 feet long

So the Tangent of the angle of the sahdow remains the same for the both trees.

We know that  Tanx=\frac{height of the tree}{length of the shadow}

\frac{height of the tree1}{length of the shadow1} = \frac{height of the tree2}{length of the shadow2}

\frac{41.8}{27} =\frac{x}{18.3}

x=\frac{41.8}{27}\times18.3 =28.3

Therefore the height of the tree is 28.3 feet

what is the answer to this question. please respond. I need the answer very quick.my teacher is going to get mad at me
amm1812

It is a ratio problem...

2 dogs need 144 feet = 2 : 144

Simplify the ratio = 1 : 72

Multiply both sides by 8 (8 dogs) = 1*8 :144*8

Simplify the ratio = 8 : 1152

8 dogs need 1152 feet of fencing

Hope this helps!

the value of n is both 5 times as much as the value of m and 36 more than the value of m. what are the values of n and m? explai
Ray Of Light [21]

You said that        n = 5m

AND                     n = m + 36 .

Well then, if those two quantities are both equal to 'n', then
they must be equal to each other, and we can write

                                               5m = m + 36

Subtract 'm' from each side:    4m =       36

Divide each side by 4 :              m =        9 .

OK.  We're half done.

Way back at the beginning, the first thing you told me
was that 'n' is 5 times the value of 'm'. 

                                   n = 5 (m)

Well !  Now we know what 'm' is, so

                                   n = 5 (9) = 45 .
