A Ferris wheel car moves from point C to point D on the circle shown below:
Circle A is shown with points C and D on the circle and the central angle C A D marked 42 degrees. The diameter is 30 feet.
HELP NOW!! 100 POINTS!!! What is the arc length the car traveled, to the nearest hundredth?
7.91 feet
8.32 feet
10.99 feet
11.89 feet
Answer:
10.99
Step-by-step explanation:
Took the test and it said it was this one :)
The arc length of the car traveled, to the nearest hundredth is 10.99feet
The formula for calculating the length of an arc is expressed as:
L = theta/360 × 2pi r
Given that
Radius r = d/2 = 30/2 =15ft
theta = 42 degrees
pi = 3.14
Substitute the given values into the formula as shown
L = 42/360×2(3.14)(15)
L = 42/360×94.2
L = 3956.4/360
L = 10.99feet
This shows that the arc length of the car traveled, to the nearest hundredth is 10.99feet

One of Carla's friends suggests that she survey only eighth-graders because they are the
oldest and probably know more about the election than younger students. Do you think
this suggestion creates a random sample? Explain.
Answer:
This example is not a random example due to the fact that it is only questioning the eighth-graders. Random sample means that the sample is chosen simply randomly and everyone has an equal opportunity to be apart of the sampling.

If the pointer in the figure is spun twice, find the probability that the pointer lands on green (G) both spins.
Answer:
25%
Step-by-step explanation:
The bottom left and top right are each a quarter of the circle and are thus 25% each. The slivers in the middle have to add up to 50% and are all evenly sized. That means that each sliver is 50/4 or 12.5%
Since there are two green slivers, we multiply 12.5% * 2 to get 25%.

The ratio of mass to volume for a type of metal is 27 g to 10 cm³ a sample of the metal has a mass of 81 g what is the volume in cubic centimeters of the sample of metal
Answer:
volume in cubic centimeters = 30 cm³
Step-by-step explanation:
Ratio of mass to volume = 27 g : 10 cm³
what is the volume in cubic centimeters of the sample of metal if mass = 81 g
Let
volume in cubic centimeters = v
Ratio of mass to volume = 81 g : v
Equate both ratios
27 g : 10 cm³ = 81 g : v
27/10 = 81/v
Cross product
27 * v = 10 * 81
27v = 810
v = 810/27
v = 30 cm³
volume in cubic centimeters = 30 cm³

Find the eighth term of a geometric sequence for which a,3 = 35 and r= 7.
Answer:
588245.
Step-by-step explanation:
nth term = an = a1 r^(n-1) where a1 = the first term
a3 = 35 = a1 7^(3 - 1)
35 = a1* 49
a1 = 35/49 = 5/7
So the 8th term = (5/7)* (7)^7
= 588245

на восемь групп, по четыре команды в каждой. Группы называют латинскими буквами от А
до Н. Какова вероятность того, что команда Франции, участвующая в чемпионате, окажется
в одной из групп А, В, С или D?
Ответ:
Ответ:
P = 1/4Объяснение:
Probability of an event happening = Number of ways it can happen / Total number of outcomes
Number of ways it can happen: 1 (there is only 1 group with french team in it)
Total number of outcomes: 4 (there are 4 groups)
So the probability = 1/4
------------------------------------------------------------------------------------
Вероятность возникновения события = Количество способов которыми это может произойти / Общее количество исходов
Количество способов которыми это может произойти: 1 (есть только 1 группа с французской командой в ней)
Общее количество исходов: 4 (есть 4 группы)
Таким образом вероятность = 1/4

The diameter of a circle is 6 kilometers. What is the area?
d=6 km
Give the exact answer in simplest form.
square kilometers
Answer:
28.27 rounded orrrr 28.27433388 not rounded.
Step-by-step explanation:
area of circle=πr^2
radius=3 km
3^2=9
9*π
Step-by-step explanation:
Area of a circle = πr²
Radius (r) =1/2 Diameter
=60/2

Area = π x (30)²
= π x 900
= 2027km²
Are these proportional?
6/9 and 2/3
Answer:
yes.
Step-by-step explanation:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
6/9 divided by 3/3= 2/3

explain why zero is excluded from the domain and range
Answer:
The range is also all real numbers except zero. You can see that there is some point on the curve for every y -value except y=0 . Domains can also be explicitly specified, if there are values for which the function could be defined, but which we don't want to consider for some reason.

The temperature at sunrise is 40°F. Each hour, the temperature rises 4°F. Write an equation that models the temperature y, in degrees Fahrenheit, after x hours. What is the graph of the equation?
Write an equation that models the temperature y, in degrees Fahrenheit, after x hours.
Answer:
y = 4x + 40
Step-by-step explanation:
At sunrise, 0 hours have passed, meaning x = 0.
When x = 0, the temperature is 40, meaning that 40 is the y-intercept.
And every x hours the temperature rises by 4 degrees F

After simplifying the inequality we get 6 < 28 which is true. Hence the given statement is true.
An inequality is a mathematical statement that uses the inequality symbol to indicate the relationship between two expressions. Both sides of an inequality sign have different expressions.
It signifies that the expression on the left should be more or smaller than the expression on the right, or vice versa. Literal inequalities occur when the relationship between two algebraic expressions is defined using inequality symbols.
The given inequality is:
3(2 - b) < 10 - 3(b-6)
Distribute the number inside the bracket,
6 - 3b < 10 - 3b + 18
Add 3n on both sides,
6 < 10 + 18
Simplifying it,
6<28

Cool-down Melanie and Kala each started solving equation 2 for x. 1 (7x – 6) = 6x – 10 The result of Melanie's first step was: 3.5x = 6 = 6x - 10 The result of Kala's first step was: 7x - 6= 12x - 20 One of them made an error. Who was it, and what was the error?
I need to find who made the error and what was the error
Answer:
Kala's first step.
Step-by-step explanation:
Solving linear equations.
Step 1: Simplify each side, if needed. Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side. Step 3: Use Mult./Div. Step 4: Check your answer. I find this is the quickest and easiest way to approach linear equations. Example 6: Solve for the variable.But Kala did not do that. Instead, she skipped the first stages and moved on ahead, making her equation invalid.
