A passenger train has tickets available for 12 window seats and 8 aisle seats. The next person to buy a ticket will be randomly assigned to one of
those seats. What is the probability that the next person will be assigned to an aisle
seat?

Answers

Answer:

2/5

Step-by-step explanation:

There is an 8/20 chance that the next person will receive a window seat. You simplify that probability to get your answer. 8/20 becomes 2/5. So the answer is 2/5.

Answers

Answer:

x = 15

Step-by-step explanation:

Create and solve an equation of ratios. We can do this because the smaller triangle and the larger one are similar.

x 5 + x

------- = -----------

9 9 + 3

Cross-multiplying, we get 12x = 45 + 9x,

which simplifies to 3x = 45

Solving for x, we get x = 15

The volume of clay sculpture is 540 cubic inches.What is the volume of similar sculpture that is smaller by a scale factor of 1/2.

Answers

Answer:

67.5 in³

Step-by-step explanation:

Given that :

Volume 1 = 540 in³

Volume 2 of similar shape = x ; if the scale factor = 1/2

Volume of a shape = length * width * height)

The scale factor = 1/2

Volumetric factor = 1/2 * 1/2 * 1/2 = 1/8

Hence, the volume of similar sculpture will be :

540 in³ * 1/8 = 67.5 in³

Type the correct answer in each box. Use numerals instead of words. The sum of two numbers is 84. The square of the first number is 6 more than the second number. Write a system of equations to find the value of x, the first number, and y, the second number.

y = -x + ____
y = x^2 + ____

Answers

Answer:

84, -6

Step-by-step explanation:

y= -x+84

y= x^2+(-6)

The system of equations used to find the value of x is:

y = -x + 84

y = x² - 6

Let x represent the first number and y represent the second number.

The sum of the two numbers is 84, hence:

x + y = 84

y = -x + 84 (1)

The square of the first number is 6 more than the second number. Hence:

x² = 6 + y

y = x² - 6 (2)

The system of equations used to find the value of x is:

y = -x + 84

y = x² - 6

Answers

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

we can find angle C b/c the angles of a triangle always add to 180 , soo

180= C + 81 +63.5

35.5 = C

now that we have angle C and we know the Hyp we can use sin to find side g

where g = Opp and Hpy = 13.8 for this question

Sin(35.5) = Opp / 13.8

13.8*Sin(35.5) = Opp

8.0137 = Opp

g = 8.0137

next they ask for the area of the biggest triangle ABC ( there are two smaller ones when you use D )

we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.

we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj

Cos(35.5) = Adj / 13.8

13.8*Cos(35.5) = Adj

11.234794 =Adj

now solve for DB using cos again but with the other smaller triangle where Adj = DB now

Cos(63.5) = Adj / 8.9

8.9*Cos(63.5) = Adj

3.971160

add these two Adjs together to get the total 'a' side

15.205954

now plug in side a as the base and g as the height of our biggest triangle

Area = 1/2 * 15.205954 * 8.0137

Area = 60.9159

rounded to 2 sig figs

Area = 60.92 :) hope you get an "A" :P
