a tree casts a shadow that is 24 feet in length. If the angle of elevation is 30 degrees, which of the following best represents

Ratling [72]

Answer:

13.856 feet

Step-by-step explanation:

The height of the tree and its shadow forms a right angle. Together with the line joining the pit of the shadow and the tree make a right triangle.

We can use the trigonometric ratio tangent to find its height.

tan = opposite/adjacent

tam 30° = x/24

height = 24 × tan 30°

= 24 ×0.57735

= 13.856 feet

Find the least common denominator for these

baherus [9]

Answer:

The least common denominator of the two rational expressions is $(x+2)^{2}\cdot (x+3)$ .

Step-by-step explanation:

Let be the following rational expressions:

$\frac{x^{3}}{x^{2}+4\cdot x + 4}, \frac{-9}{x^{2}+5\cdot x + 6}$

Then, we factor each denominator:

$\frac{x^{3}}{(x+2)^{2}}, \frac{-9}{(x+3)\cdot (x+2)}$

Now, we compare each denominator to find all missing binomials so that each expression may have a common denominator:

$\frac{x^{3}}{(x+2)^{2}} \rightarrow (x+3)$

$\frac{-9}{(x+3)\cdot (x+2)} \rightarrow (x+2)$

Hence, we conclude that least common denominator of the two rational expressions is $(x+2)^{2}\cdot (x+3)$ .

Add 1/6+3/4+2/3. Simplify the answer and write it as a mixed number, if possible.

jarptica [38.1K]

Find the lowest common denominator for the 3 fractions. It is 12.
Rewrite each fraction with the denominator 12.
1/6 = 2/12
3/4 = 9/12
2/3 = 8/12
2/12 + 9/12 + 8/12 = 19/12
This can be written as the mixed number 1 7/12.
The answer is D) 1 7/12

FOUR FRIENDS SHARE 3 SHEETS OF PAPER EQUALLY.

jenyasd209 [6]

Answer:

$\frac{3}{4}$ of a sheet of paper

Step-by-step explanation:

Hi!

This isn't the easiest to explain with numbers but I'll do it with an example instead.

If you had 60 cookies and had to split it equally with you and one of your other friends, how would you do it?

You would do $\frac{60}{2}$ , right? Because you have 60 cookies and you're dividing it amongst 2 people.

It's the same idea here!

We take the number of sheets of paper, and we divide it by the number of people we have to share it with.

so we do $\frac{3}{4}$ . You don't even have to simplify in this case because this is a fraction and this is the simplest form of this fraction as well

I hope this made sense, let me know if you have any questions
