A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.
Explain how to find the arc length exactly, and then approximate it to one decimal place.
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in

Answer: [tex]-2x^2 + 10x-8[/tex]
Step-by-step explanation:
To find the product of the binomials, we first need to find the linear equations for the lines.
Using the rise over run method for f(x), we can see that the line rises 2 units for every 1 unit ran. 2/1 = 2, so we know the slope is 2, and we can see that the y-intercept on the graph is -2.
Equation: [tex]f(x) = 2x-2[/tex]
Using the rise over run method for g(x), we can see that the line rises -1 unit for every 1 unit ran. -1/1 = -1, so we know the slope is -1, and we can see that the y-intercept on the graph is 4.
Equation: [tex]g(x) = -x+4[/tex]
Multiplying the binomials:
[tex](2x-2)(-x+4)[/tex]
Use the FOIL method:
First: 2x * -x
Outside: 2x * 4
Inside: -2 * -x
Last: -2 * + 4
[tex]-2x^2+8x+2x-8\\\\-2x^2 + 10x-8[/tex]

A circle has a diameter of 12 inches. What is its area in terms of π?
6 π
36π
12 π
8 π
those are the the answers whichone is it
Answer:
36π
Step-by-step explanation:
Since you have to use terms of pi you just leave out pi out of the formula
A = πr² so it would be
A = r² Radius is half of diameter so half of 12 = 6
A = 6²
A = 36
Than you add pi

Which equation has no real solutions?
A) -2x^2 = -168
B) 4x² + 76 = 32
C) 25x² = 1
D) 43 - X^2 = 12
The variables x and y are related proportionally. When x = 6, y = 16. Find y when x = 33.
Answer:
y=43
Step-by-step explanation:
y=x+10
y=33+10
y=43
To find the value of y when x=33, knowing that x and y are directly proportional, we first calculate the proportionality constant from the given values and apply it to find y=88 when x=33.
The task is to find the value of y when x is given, knowing that x and y are directly proportional. Thus, we first find the proportionality constant using the given values of x=6 and y=16. The formula for direct proportionality is y = kx, where k is the proportionality constant. Solving for k we get k = y/x => k = 16/6. Once we have the value of k, we can find y for x=33 by rearranging the formula to y = (16/6) * 33.
After performing the calculation, we find:
k = 16/6y when x=33 is y = (16/6) * 33Therefore, y is 88 when x is 33, as they are directly proportional.
A row of tiny red beads is placed at the beginning and at the end of a 20-centimeter bookmark
A row of the same beads is also placed every 4 millimeters along the bookmark
How many rows of the beads are used on the bookmark?
Enter your answer in the box
Answer:
There are 50 beads on the bookmark.Step-by-step explanation:
To know the number of rows of the beads are used on the bookmark, we just need to divide.
Notice that the bookmark is 20 centimeters long, and each bead is 4 milimiters. In order to divide, we need to transform centimeters to millimeters.
We know that 1 centimeter is 10 millimeters, that means 20 centimeters is 200 millimeters.
Then, the division is
[tex]\frac{200mm}{4mm} =50[/tex]
Therefore, there are 50 beads on the bookmark.
51 rows of beads are used on the bookmark.
To determine the number of rows of beads on the bookmark, we need to follow these steps:
1. Convert the length of the bookmark from centimeters to millimeters to match the unit of measurement for the spacing between rows of beads. Since there are 10 millimeters in a centimeter, the bookmark is [tex]\( 20 \text{ cm} \times \frac{10 \text{ mm}}{1 \text{ cm}} = 200 \text{ mm} \)[/tex] long.
2. Determine the distance between each row of beads. The problem states that there is a row of beads every 4 millimeters.
3. Calculate the number of intervals between the beads along the bookmark. To do this, divide the total length of the bookmark by the spacing between each row of beads: [tex]\( \frac{200 \text{ mm}}{4 \text{ mm/row}} = 50 \) intervals.[/tex]
4. Since we have an interval at each end of the bookmark where a row of beads is placed, we already have two rows of beads. For each interval between these end rows, there is an additional row of beads. Therefore, we have one more row of beads than the number of intervals.
5. Add one to the number of intervals to account for the starting row of beads: [tex]\( 50 \text{ intervals} + 1 = 51 \)[/tex] rows of beads.
Thus, there are 51 rows of beads used on the bookmark.

x ≥ -7.8
D
x ≤ 7.8
Answer
The answer is B
Step-by-step explanation:
Its correct
Answer:
The answer is B.
Step-by-step explanation:
In order to solve x, you have to make x the subject by substracting 11.6 to both sides:
[tex]11.6 + x \geqslant 4.8[/tex]
[tex]11.6 + x - 11.6 \geqslant 4.8 - 11.6[/tex]
[tex]x \geqslant - 6.8[/tex]
You and some friends buy tickets to a raffle at your school. You can each buy one ticket. In total 150 tickets were sold. The probability that on of your friends win the raffle is 1/30. How many friends of yours bought tickets
Answer:5
Step-by-step explanation:
Given
There are total of 150 ticket
If the probability to win a raffle is [tex]\frac{1}{30}[/tex]
[tex]Probability =\frac{\text{Favorable outvome }}{\text{Total outcome}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{\text{Total no of tickets}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{150}[/tex]
no of tickets bought[tex]=\frac{150}{30}=5[/tex]
and no of tickets bought=No of friends
Therefore there 5 persons who bought tickets
