Answer:
20.5 degrees
Step-by-step explanation:
So when the arc is being made from two lines coming out from the center, the measure of the arc is the same as the angle of the lines.
So the measurement of 41 degrees for the arc is also the angle of line OB and line OC.
Now that center line is the diameter, which means it is 180 degrees
So you can find the angle of line OA and OB:
180 - 41 = 139
Then, to find x you need to recognize that OB and OA is actually the radius of the circle, which means they are the same length.
This makes it an isosceles triangle. So, the angle of OB and BA is the same as OB and BA. The measurement of all the angles in a truianbgle is 180 degrees, so to find the measurement of x, you need to subtract 139 from 180:
180-139 = 41
And then divide by two to find the remaining two angles:
41/2 = 20.5
and that is x :)

Answer:

Step-by-step explanation:
Put in '5' where 'x' is
2 (5)^2 - 5 = 45
What is the equation: [tex]2x^2-5[/tex]
What do we want to find: f(5)
To find f(5), we must plug the value '5'
⇒ into the 'x' position
⇒ f(x)
So: [tex]f(5) = 2(5^2)-5 = 2 * 25 - 5 = 50 -5 = 45[/tex]
Thus f(5) = 45

hello, id like to order3 halves of a cupcake for my family plus some extra for my 2 friends.
Answers
Answer:
They'll each want a quarter of a cupcake.
Step-by-step explanation:
The number of people in the family is 14.
The number of cupcakes ordered is 4.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Number of cakes for the family = 3 (1/2)
Number of friends = 2
Now,
Each person's amount of cake = 1/4
The number of people in the family.
= 3(1/2) ÷ 1/4
= 7/2 x 4
= 14
The total number of cupcakes ordered.
= 2 x 1/4 +3(1/2)
= 1/2 + 3(1/2)
= 1/2 + 7/2
= 8/2
= 4
Thus,
There are 14 people in the family.
The total number of cupcakes ordered is 4.

Find the 48th term.
Answers
Answer:
so you should add 6 to 13 in case to find 19, then add 6 to 19 to get to 25.
so the first is 13 and we keep adding 6 to get to the answer. we do it 47 times. so we have 13+ (6) (47) = 295 which is the 48th term.
The 12th term of the arithmetic sequence13, 19, 25,... is 79.
What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, an arithmetic sequence 13, 19, 25,...
The first term a₁ = 13 and the common difference is = (25 - 19) = (19 - 13) = 6.
We know nth term of an arithmetic sequence is aₙ = a₁ + (n - 1).d.
∴ The 12th term of this arithmetic sequence is a₁₂ = a₁ + (12 - 1).d
a₁₂ = 13 + (12 - 1).6.
a₁₂ = 13 + 11.6
a₁₂ = 13 + 66.
a₁₂ = 79.

The denominator would be x = -3.
Option (A) is correct.
What is the denominator?
A denominator is a bottom number in a fraction. It represents the divisor or the number by which the numerator is being divided.
In this case, the denominator is x^2+6x+9. To find the values of x for which the denominator is equal to zero, we need to set the denominator equal to 0 and solve for x. The equation would be x^2+6x+9=0. By factorizing the denominator we get (x+3)^2=0.
x + 3 = 0
x = -3
Hence, the denominator would be x = -3.
Option (A) is correct.

in a square 2 sides with a diagonal creates a right-angled triangle, with the diagonal being the Hypotenuse (the side opposite of the 90° angle).
the diagonal is 3+3 = 6 units long.

Length: 20, Width=34
Step-by-step explanation:
Say the length of the width is w, and the length of the length is l. Then, we can establish an equation of W=2L-6. Since the area of a rectangle is W*L, we can substitute W with 2L-6. If we multiply 2L-6 and L, we get [tex]2L^{2} -6L[/tex]=680. We can simplify this equation by dividing everything by 2. We then get [tex]L^{2}-3L=340[/tex]. If we solve for L, we get 20. Now, we plug 20 into the equation, W=2L-6. Since W=2(20)-6, which simplifies to W=40-6 which is 34, we get a width of 34.

When creating a histogram it is best to create a range for the different variables that are available.
So for the sake of covering all the possible ranges from 1 - 22, let's divide it into 5 categories.

Now that we have set ranges for the different variables, we then find the frequencies.
