The lines through the sides in the circle indicate that the three sides are all of the same length, and therefore share the same angle.

A shape inside a circle will always have its angles equal 360, so you can find the individual angle with the following equation:

120 + 3x = 360

Subtract 120 from both sides.

3x = 240

Divide both sides by 3.

x = 80

mBC's angle is 80 degrees.

A gambler is deciding whether or not to take a bet. She must pay $40 to take the bet, but if she wins, she will profit $225. The
kicyunya [14]

Answer:

The classification of that same given problem is outlined in the following portion on the clarification.

Step-by-step explanation:

⇒  E[x]=\Sigma_{x=0}^{x} \ x \ f(x)

On putting the values, we get

⇒         =0\times \frac{3}{4}+225\times \frac{1}{4}  -40\times 1

⇒         =\frac{225}{4}-40

On taking L.C.M, we get

⇒         =\frac{225-160}{4}

⇒         =\frac{65}{4}

⇒         =16.25

1...

Whether she wins she would receive $225 with even a 1/4 chance, then she will lose and maybe get $0 with such a 3/4 chance although if she takes a gamble anyway though she will either have to compensate $40 wp 1.

2...

She seems to want the capital to benefit or win.

Answer:

1.No, 143 is not a prime number. The list of all positive divisors the list of all integers that divide 143 is as follows: 1, 11, 13, 143. To be 143 a prime number, it would have been required that 143 has only two divisors, itself and 1.

2.Since the polynomial can be factored, it is not prime.

The height of a certain banner is equal to one third of its length. If the banner is 5 ft tall, write the equation that can be u
pav-90 [236]

Answer:

L=3h

Step-by-step explanation:

Let height of a banner be h, then we know that this is \frac{1}{3} of the length L of the banner; so we have

h=\frac{1}{3} L .

Now we can rearrange this equation to solve for the length of the banner given it's height:

L=3h

So there we have it!

If the banner is 5 ft tall, then it's length will be:

L=3*5=15ft
