GREYUIT [131]3 years ago

Answer:

52 square units

Step-by-step explanation:

Drop a perpendicular from the top left vertex to the bottom base creating a right triangle. You have a 30-60-90 right triangle with the ratio of the lengths of the sides being 1 : sqrt(3) : 2

Then, the height of the trapezoid is the triangle's opposite leg to the 60-deg angle.

The triangle's adjacent leg to the 60-deg angle is half the hypotenuse, or 3 units.

The height is sqrt(3) times the adjacent leg.

The base of the trapezoid has length 3 + 7 + 3 = 13

A = (b1 + b2)h/2

A = (13 + 7)(3sqrt(3))/2

A = 51.96

Answer: 52 square units

H/ 1/2 = 6<br> h= ?<br><br><br> PLEASE HELP ASAP! I REALLY NEED THIS!
ad-work [718]

Answer:

h = 3

Step-by-step explanation:

Dividing by a fraction is the same as multiplying by its reciprocal.

So h / (1/2) is the same as h * 2 or 2h

2h = 6

Divide both sides by 2 to isolate the variable h.

2h/2 = 6/2

h = 6/2

h = 3

A total of 8 representatives need to be chosen from a group of 40 students, of which 24 are female and 16 are male. In how many
Diano4ka-milaya [45]

Answer:

Probability = 0.0147

Step-by-step explanation:

To find this, we need to know the number of ways the representatives can be picked overall, and then the number of ways 3 females and 3 males can be the representatives. The fraction of the two will be the probability.

The total number of ways the representatives can be picked is the combination of a pool of 40 students and choosing 8 is; C(40,8) = 40!/((8!)(40 - 12)!)

= 76904685

We have gotten the number of ways the representatives can be picked.

Now let's find how many ways can the jury consist of 3 females and 3 males

For the males, there are 16 in the pool and we're picking 3:

Thus, C(16,3) = 16!/((3!)(16 - 3)!) = 560

For the females, there are 24 in the pool and we're picking 3:

Thus, C(24,3) = 24!/((3!)(24 - 3)!) = 2024

Thus, number of men and women choices = 2024 x 560 = 1133440

So; probability = 1133440/76904685 = 0.0147

The function C(x) = 49.5x + 19.5 represents the cost (in dollars) of buying x concert tickets. How much does it cost to buy four
Reika [66]
To buy four tickets it would cost $217.5 because
C(x) = 49.5(4) +19.5
C(x) = 198 +19.5
C(x) = 217.5
With $465 you could buy 9 tickets.
C(x) = 49.5(9) +19.5
C(x) = 445.5 + 19.5
C(x) = 465
