F the area of an equilateral triangle is 9√3 sq ft, how long is a side?

ANTONII [103]3 years ago

The area of an equilateral triangle is always:

A=√((3s^4)/16) or if you prefer: A=(s^2/4)√3

So if A=9√3 we have:

9√3=(s^2/4)√3

9=s^2/4

s^2=36

s=6 feet

Make a list of all 3 digit numbers using the digit 5, 2, and 6

HACTEHA [7]

Answer:

SOLUTION #1

If the digits are allowed to repeat, the answer is 27. (There are three ways to fill digit 1, three ways to fill digit 2, and three ways to fill digit 3. Therefore, there are 3 x 3 x 3 = 27 possibilities.)

SOLUTION #2

If the digits are NOT allowed to repeat, the answer is 6. (There are three ways to fill digit 1, only two ways to fill digit 2, and only one way to fill digit 3. Therefore, there are 3 x 2 x 1 = 6 possibilities.)

Find the value of x and y.<br><br>help me out ASAP!!

il63 [147K]

Step-by-step explanation:

13x + 15 = 19x - 9 ( being opposite sides of parallelogram)

19x - 13x = 15 + 9

6x = 24

x = 24 / 6

x = 4

4y + 7° + 10y - 37° = 180° {being co-interior angles }

14y = 180° - 7° + 37°

14y = 210°

y = 210°/ 14

y = 15°

Hope it will help :)

Suppose the total benefit of watching 1 baseball game is 100, the total benefit of watching 2 games is 120, and the total benefi

77julia77 [94]

Answer:

A. 5

Step-by-step explanation:

The marginal benefit of an article, $B_m$ is calculated as:

$B_m=\frac{DB_t}{DQ}$

Where $DB_t$ is the change in the total benefit of the article, and $DQ$ is the change in the units of the article.

If we want to know the marginal benefit of watching the 3rd game, we need to use the information of total benefit of watching 2 games and 3 games.

In this case, the total benefit of watching 2 games is 120 and the total benefit of watching 3 games is 125, so $DB_t$ and $DQ$ are equal to:

$DB_t=125-120=5$

$DQ = 3 - 2 = 1$

Then, the marginal benefit of watching the third game is:

$B_m=\frac{5}{1}=5$
