What is the length of the side opposite the 60 degree angle?

FinnZ [79.3K]

My guess is 30 because every triangle has to add up to 180. 90+60 is 150 180-150 is 30

A bridge hand in which there is no card higher than a nine is called a Yarborough. Specify an appropriate sample space and deter

Vilka [71]

Answer:

The probability of Yarborough when you are randomly dealt 13 cards out of a well-shuffled deck of 52 card is 0.000547.

Step-by-step explanation:

The number of ways you can choose a set of 13 different cards from a deck of 52 cards is given by 52P13.

Hence the unordered sample space has 52P13 equally likely outcomes. The number of outcomes with no card above a nine is 32P13.

This leads to the same value for the desired probability of a Yarborough:

32P13 / 52P13 = 0.000547.

Two buses leave a station at the same time and travel in opposite directions. One bus travels

natima [27]

Answer:

63 miles per hour

54 miles per hour

Step-by-step explanation:

Let the two buses be represented as bus A and bus B.

bus A and bus B leave a station at the same time and travel in opposite directions.

Let the speed of bus A be A miles per hour.

Let the speed of bus B be B miles per hour.

One bus travels 9 miles/hour slower than the other.

Let bus A be the faster bus.

This means that the speed of bus B is B = A - 9

If the two buses are 585 miles apart after 5hours, this means that after 5hours, the total distance travelled by bus A and bus B is 585 miles.

Distance travelled by bus A in 5 hours = speed × time = 5A

Distance travelled by bus B in 5 hours = speed × time = 5B

5A + 5B = 585 - - - - - -1

Substituting B = A - 9 in equation 1

5A + 5(A - 9) = 585

5A + 5A - 45 = 585

10A = 585 + 45 = 630

A = 630/10 = 63 miles per hour

B = A - 9 = 63 - 9 = 54 miles per hour

I’ve been stumped on this question for a while (picture included)

julsineya [31]

Answer:

Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.

Red = $\sqrt{x+2}$

Blue = $3x^2-4x-1$

By graphing those equations, we can determine the solution(s)

The points where the graphs intersect would be your coordinates to derive your solution

Red = (1.864, 1.966)

Blue = (-0.427, 1.254)

The solutions would be the x-value of the ordered pair, in this case,

x = 1.864 AND x = -0.427
