A man is 6 feet tall. To find the height of a tree, the shadow of the man and the shadow of the tree were measured. The length o

Sidana [21]

The answer is 16 ft because 6 ft tall over 4 feet 6 inches (4.5) is equal to x (tree's height) over 12 ft. You cross multiple and get 72 = 4.5x then you take 72 and divide by 4.5 to get the tree's height

$\frac{6}{4.5} = \frac{x}{12}$

In how many ways can a person enter a room that has three doors and leave it by (a) a different door? (b) any door? How do i do

White raven [17]

Part (a)

Label the doors A, B, C.

If a person goes through door A, then they have 2 choices (B or C) to pick as an exit. Similarly, if they go through door B, then they have 2 choices for an exit (A or C). Finally, if they go through door C, then they have 2 choices for an exit (A or B).

We have 3 choices for the entrance, and 2 choices for the exit.

So overall, 3*2 = 6 different combinations are possible.

Those 6 combos are

AB, AC, BA, BC, CA, CB

<h3>Answer: 6</h3>

=============================================

Part (b)

This is effectively the same as part (a), but we can now re-use the entrance door. For any door we enter, we have 3 choices to pick from for the exit. There are 3 doors, so 3 entrances and 3 exits, meaning 3*3 = 9 different combinations.

Those 9 combos are

AA, AB, AC, BA, BB, BC, CA, CB, CC

<h3>Answer: 9</h3>

Divide the square root of 81 by the difference between the product of-1 and -3 and the square root of 4

kherson [118]

Answer: $\frac{9}{1}$

Step-by-step explanation:

FIrst find the square root of 81.

$\sqrt{81} = 9$

The square root of 81 is 9.

FInd the product of -1 and -3 by multiplying the -1 by -3.

-1 * -3 = 3

next find the square root of 4.

$\sqrt{4} = 2$

Now it said divide the square root of 81 which is 9 by the difference between 3 and 2 and the difference between 3 and 2 two is 1.

Thos means that the answer will be 9/1.
