Answer:
Exact Area = 24pi square cm
Approximate Area = 75.36 square cm (when using pi = 3.14)
Note: "square cm" can be abbreviated to "cm^2" without quotes.
=============================================================
Explanation:
Let's find the area of the full circle with radius r = 12
A = pi*r^2
A = pi*12^2
A = 144pi
This is the exact area of the full circle in terms of pi. To get the approximate area, you would replace pi with something like 3.14 (though you could use more decimal digits in pi to get a more accurate area).
We found the area of the full circle, but we only want a pie slice of it. Each slice is 60 degrees, out of 360 total. So that means we want 60/360 = 1/6 of the full area.
In other words, there are 6 slices because 360/60 = 6, which means we'll divide the area we got by 6
(144pi)/6 = (144/6)pi = 24pi
The exact area of the pie slice is 24pi square cm
If you used the approximation pi = 3.14, then that leads to an approximate answer of 24*pi = 24*3.14 = 75.36 square cm
Sixty percent of the people surveyed use sunscreen. A random number generator was used to simulate the results of asking the next three people. The numbers 0–5 represent people who use sunscreen, and the numbers 6–9 represent people who do not use sunscreen. What is the probability that two of the next three respondents use sunscreen?
Answer:
[tex]Pr = 0.50[/tex]
Step-by-step explanation:
Given
See attachment for complete question
Required
Probability that 2 of 3 use sunscreen
From the attached data, we have:
[tex]S = \{275, 738, 419, 582, 987, 436, 578, 472, 178, 839\}[/tex]
[tex]n(S) = 10[/tex]
Events where 2 of the 3 uses sunscreen is:
[tex]x = \{275, 419, 582, 436, 472\}[/tex] --- i.e. where 0 -5 represents sunscreen
[tex]n(x) = 5[/tex]
So, the required probability is:
[tex]Pr = \frac{n(x)}{n(S)}[/tex]
[tex]Pr = \frac{5}{10}[/tex]
[tex]Pr = 0.50[/tex]

cookies for $3.50. How much did each person pay for a cookie? And who
had the better deal?
Answer:
Ms. Powell paid around 33 cents for each cookie
Ms. Malley paid around 43 cents for each cookie
Ms. Powell had the better deal
Step-by-step explanation:
Divide the amount paid with the amount of cookies bought so 4 ÷ 12 = 0.3333... and 3.50 ÷ 0.4375...

Step-by-step explanation:
So the area of a triangle is (Base * Height) / 2. The base, which is where the triangle "sits" is 10 in. The height is 5 in.
With this, these numbers can both be plugged in to get the answer:
(10 * 5) / 2

In the above figure, m∠P = 125° and m∠Q = (5x)°. If angles P and Q are supplementary angles, what are the value of x and the measure of angle Q?
Answer:
I had the same question and the answer is x = 11, m∠Q = 55°
The value of x is 11 and measure of <Q is 55 degree.
What are supplementary angle?Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°.
We have,
m∠P = 125° and m∠Q = (5x)°.
and, P and Q are supplementary angles.
Using the property of Supplementary Angle
<P + <Q = 180
125 + 5x= 180
5x = 55
x= 11
Thus, the measure of <Q
= 5x
= 55 degree

Evaluate cos 17x/6
ill give brainlist
The value of cos(17π/6) = cos(5π/6) = -√3/2.
Hence, cos(17π/6) evaluates to -√3/2.
To evaluate cos(17π/6), we can use the unit circle and the properties of cosine.
First, let's determine the reference angle.
The reference angle is the acute angle formed between the terminal side of the given angle and the x-axis.
The angle 17π/6 is greater than 2π, which means it completes more than one full revolution around the unit circle.
To find the reference angle, we can subtract 2π (or 12π/6) from 17π/6:
17π/6 - 12π/6 = 5π/6
Now, we can evaluate the cosine of the reference angle (5π/6).
In the unit circle, the reference angle 5π/6 corresponds to the point (cos(5π/6), sin(5π/6)).
The cosine value is represented by the x-coordinate of this point.
For the reference angle 5π/6, the x-coordinate is -√3/2.
Therefore, cos(17π/6) = cos(5π/6) = -√3/2.
Hence, cos(17π/6) evaluates to -√3/2.

Which situation involves a conditional probability? O A. The probability that you roll a 6 on a number cube B. The probability that you make two free throws in basketball C. The probability that you make a second free throw given that you made the first free throw O D. The probability that you are given a book for your birthday
Answer:
c
Step-by-step explanation:
its conditional because you might not make the first free throw.
The situation that involves a conditional probability is the probability that you make a second free throw given that you made the first free throw.
Thus, option (C) is correct.
Conditional probability refers to the probability of an event occurring given that another event has already occurred.
In this case, the probability of making a second free throw is dependent on the condition that you made the first free throw.
Therefore, the probability that you make a second free throw given that you made the first free throw.

Answer:
1: x=18 2: x=7 3: x=12
Step-by-step explanation:
1: 7x+3=9x-33
2x=36
x=18
2: 16x+(6x=26)=180
22x=154
x=7
3: (10x-17)-(2x-3)=90
8x-14=104
x=12
Answer and Step-by-step explanation:
1.
7x + 3 = 9x - 33
Subtract 7x from both sides, and add 33 to both sides of the equation.
36 = 2x
Divide both sides by 2.
x = 18
2.
6x + 26 + 16x = 180
Combine like terms.
22x + 26 = 180
Subtract 26 from both sides of the equation.
22x = 154
Divide 22 from both sides of the equation.
x = 7
3.
90 + 2x - 3 = 10x - 17
Add 17 to both sides of the equation, subtract 2x from both sides of the equation and combine like terms.
104 = 8x
Divide 8 from both sides of the equation.
x = 13

Will every function have a hole? Why or why not?
Answer:
No, not every function will have a hole. This is considered a special case. A typical function is one that can be written as a fraction of two polynomials where the denominator is not zero. In a special case (when there is a hole), a factor may appear in both the numerator and denominator.

Answer:
0 ≤ x ≤ 2 (i assumed that the arrows included 0 and 2).
Step-by-step explanation:
One arrow shows 0 and greater (as it is pointing right) and the other shows 2 and smaller (as it is pointing left). The arrow pointing right has the equation of:
x ≥ 0 (where x is a random number)
The arrow pointing left has the equation of:
x ≤ 2 (where x is a random number)
Assuming that you need to find an equation so that x fits both inequalities, we combine them into one inequality and get:
0 ≤ x ≤ 2
Find the value of x in the isosceles triangle shown below
Answer:
The answer is 12
Hope it helps
Answer:
x = 12
Step-by-step explanation:
Since the 2 legs and base angles are congruent the triangle is isosceles.
The line from the vertex to the base is a perpendicular bisector dividing the triangle into 2 right triangles.
Using Pythagoras' identity in either of the 2 right triangles with legs 3 and [tex]\frac{1}{2}[/tex] x , hypotenuse [tex]\sqrt{45}[/tex] , then
([tex]\frac{1}{2}[/tex] x )² + 3² = ([tex]\sqrt{45}[/tex] )²
[tex]\frac{1}{4}[/tex] x² + 9 = 45 ( subtract 9 from both sides ²)
[tex]\frac{1}{4}[/tex] x² = 36 ( multiply both sides by 4 to clear the fraction )
x² = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12
