Answer:

12.4

Step-by-step explanation:

The distance between (7,21) and (-5,18)

d =sqrt( (-5-7)^2 + (18-21)^2)

  = sqrt(( -12)^2 + (-3)^2)

  = sqrt(144+9)

  = sqrt(153)

  =12.36931688

To the nearest tenth

12.4

Amanda [17]

Answer:

x=44

m∠1=118°

m∠2=62°

Step-by-step explanation:

Part A: They are supplementary angles, so

2x+30+62=180

Simplify like terms,

2x+92=180

We subtract 92,

2x=88

Divide by 2,

x=44

Part B:

m∠1=2x+30 because ∠2 is vertical to 2x+30.

Plug in 44 for x,

m∠1=2(44)+30

Simplify,

m∠1=118

m∠2=62° because it is a vertical angle to the 62° angle.

In the diagram below, XY and YZ are tangent to O which expression gives the measure of XYZ?
icang [17]

The solution of this question will make use of the Two Tangents from Point Theorem which states that "the measure of an angle formed by two tangents drawn from a point outside the circle is half the the difference of the intercepted arcs".


We can also see that the measure of arcs are: \overarc{XWZ}=245^{\circ} and\overarc{XZ}=115^{\circ}

Thus, as per the theorem, the measure of the \angle XYZ can be calculated as:

m\angle XYZ=\frac{1}{2}(\overarc{XWZ}- \overarc{XZ})

Therefore, we get:

m\angle XYZ=\frac{1}{2}(245^{\circ} -115^{\circ})

Thus, out of the given options, option B is the correct option.

What is the unit rate for 875.52 kilometers in 38.4 hours? Enter your answer, as a decimal, in the box.
serious [3.7K]
We are given:
number of kilometers = 875.52 km
time = 38.4 hours

We need to calculate the unit rate, which means that we need to find the number of kilometers in one hour.
To do so, we will simply divide the total number of kilometers by the total time as follows:
unit rate = 875.52 / 38.4 = 22.8 km/hour

A game is played using ne die. If the die is rolled and shows 3, the player wins $45. If the die shows any number other than 3,
I am Lyosha [343]

Answer:

-$13.5

Step-by-step explanation:

Let x be a random variable of a count of player gain.

- We are told that if the die shows 3, the player wins $45.

- there is a charge of $9 to play the game

If he wins, he gains; 45 - 9 = $36

If he looses, he has a net gain which is a loss = -$9

Thus, the x-values are; (36, -9)

Probability of getting a 3 which is a win is P(X) = 1/6 since there are 6 numbers on the dice and probability of getting any other number is P(X) = 5/6

Thus;

E(X) = Σ(x•P(X)) = (1/6)(36) + (5/6)(-9)

E(X) = (1/6)(36 - (5 × 9))

E(X) = (1/6)(36 - 45)

E(X) = -9/6 = -3/2

E(X) = -3/2

This represents -3/2 of $9 = -(3/2) × 9 = - 27/2 = -$13.5
