What is the approximate area of the shaded sector in the circle shown below? A. 150.8 cm2
B. 6.28 cm2
C. 37.7 cm2
D. 3.14 cm2
Answer:
C
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
(central angle is equal to the measure of the arc, that is 30° )
A = πr² × [tex]\frac{30}{360}[/tex]
= π × 12² × [tex]\frac{1}{12}[/tex]
= 144π ÷ 12
= 12π
≈ 37.7 cm² ( to the nearest tenth )

B.-3/-7
C.-7/3
D.7/3
ALSO PLEASE SAY HOW I NEED TO EXPLAIN HOW ITS EQUIVALENT
Answer:
A
Step-by-step explanation:
It is equivalent because as along as only one has the negative sign, then it will still be negative. Both being negative makes it positive and flipping the fraction changes the value.
Answer:
A
Step-by-step explanation:
the negative sign is exchangeable between the denominator and numerator because positive multiplied or divided by a negative will aways be a negative

Solve the equation below using a graphing

12. e* - In 2x = 3.7
I
Answer:
x = 0.05
x = 1.57
Step-by-step explanation:
The given equation is:
[tex]e^x-\ln 2x = 3.7[/tex]
Moving all terms to the left side:
[tex]e^x-\ln 2x - 3.7=0[/tex]
Now we define a function:
[tex]y=f(x)=e^x-\ln 2x - 3.7[/tex]
The solutions of the equation are the values of x such that y=0.
Since the function cannot be solved by algebraic methods, we use a graphing tool.
Those points where the graph crosses the x-axis are solutions of the equation.
Please refer to the graph in the figure below.
We can clearly identify there are two solutions at
x = 0.05
x = 1.57

What is the solution of the equation 70 = 1.4y ?
The solution of the equation 70 = 1.4y is 50.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 70 = 1.4y.
Seventy equal to one point four y.
In the given equation the variable is y.
We need to solve for the y.
70 = 1.4y.
Divide both sides by 1.4
70/1.4=y
Seventy divided by one point four equal to y
50=y
The value of y is fifty.
Hence, the solution of the equation 70 = 1.4y is 50.

There are 12 runners in marathon and all runners have equal chance of winning. What is the probability that a person may win a bet on the race if he has to correctly select the top 3 runners and
the order they finish in?
a) 1/1320 b) 1/1728
c) 3/1728 d) 1/12
kindly solve it using permutation technique
Answer:
A) 1/1320
Step-by-step explanation:
We know there are 12 runners in the race. Of these 12 people, one of them will get first place. In other words, 12 people have a chance of getting first place. Now there are 11 people remaining to get second place. Since one of the twelfth came first place, there are now 11 runners remaining to get second place. Finally, there are 10 people remaining. Since two of the 12 people came first and second, there are 10 people remaining who can get third place. So if a person was to correctly select the top 3 runners, then he would have a chance of 1/1320. You get this by multiplying 10, 11,12. You get 1320. since you have to pick one combination of 1st,2nd, and 3rd, the answer is A.

on a survey seven students reported how many minutes it takes them to travel to school . here are their responses 5, 12 , 4 , 8 , 7 ,10 , 12 . find the mean travel time for these students if necessary round your answer to the nearest tenth
Answer:
8.28 my guy
Step-by-step explanation:
Easy, because the 'mean' is also called the 'average'.
To find the average of a list:
1). Add up all the items on the list.
then
2). Divide the sum by the number of items on the list.
For your list:
3) 5+12+4+8+7+10+12=58
4) There are 7 students so we divide, 58/7=8.28

A. 20
B. 30
C. 45

E. 90
The sum of all the angles in a triangle is equal to 180°
Since the given triangle is an isosceles ∆ therefore the angles opposite to the equal sides with also be the same.
now from the diagram: 90° + 2x° = 180°
Therefore x = 45

Increase 60kg by 33⅓ please help!
Answer:
2000 kg is the answer.
Step-by-step explanation:
We need to increase 60 kg by [tex]33\dfrac{1}{3}[/tex].
The given value is 60 kg. We can find it by finding [tex]33\dfrac{1}{3}[/tex] of 60 kg.
[tex]=60\times \dfrac{100}{3}\\\\=20\times 100\\\\=2000[/tex]
Hence, if we increase 60 kg by [tex]33\dfrac{1}{3}[/tex], we will get 2000 kg.

Find the first five terms of the sequence given by a 1 = 2, a n = 3 a n -1 - 1.
Answer:
2, 5, 14, 41, 122
Step-by-step explanation:
Using the recursive rule with a₁ = 2
a₂ = 3a₁ - 1 = 3(2) - 1 = 6 - 1 = 5
a₃ = 3a₂ - 1 = 3(5) - 1 = 15 - 1 = 14
a₄ = 3a₃ - 1 = 3(14) - 1 = 42 - 1 = 41
a₅ = 3a₄ - 1 = 3(41) - 1 = 123 - 1 = 122
The first 5 terms are 2, 5, 14, 41, 122
Answer:
[tex]a_{1}\\\\[/tex] = 2
[tex]a_{2\\}\\\\[/tex] = 5
[tex]a_{3\\}\\\\[/tex] = 14
[tex]a_{4\\}\\\\[/tex] = 41
[tex]a_{5\\}\\\\[/tex] = 122
Step-by-step explanation:
If I've properly understood:
[tex]a_{1}\\\\[/tex] = 2
[tex]a_{n} = 3 a_{n-1}\\[/tex] - 1
so, the first 5 terms are:
[tex]a_{1}\\\\[/tex] = 2
[tex]a_{2\\}\\\\[/tex] = 3. 2 - 1 = 5
[tex]a_{3\\}\\\\[/tex] = 3. 5 - 1 = 14
[tex]a_{4\\}\\\\[/tex] = 3. 14 - 1 = 41
[tex]a_{5\\}\\\\[/tex] = 3. 41 - 1 = 122
