How to find the circumference of a circle
Answer:
Step-by-step explanation:
The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c).
circle diameter radius
A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d)
Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).
The circumference of a circle is found using this formula:
C=π⋅dorC=2π⋅r

what is a/8 - 7(3) = 4a - 78(b)
solve for b pls
Answer:
31a/624 +7/26 = b
Step-by-step explanation:
a/8 - 7(3) = 4a - 78(b)
Multiply
a/8 - 21 =4a -78b
Multiply each side by 8 to get rid of the fractions
8(a/8 - 21) =8(4a -78b)
a - 168 = 32a -624b
Subtract 32a from each side
a -32a -168 = 32a -32a -624b
-31a -168 = -624b
Divide each side by -624
(-31a -168)/-624 = -624b/-624
(31a+168)/624 = b
31a/624 +7/26 = b
Answer:
b = (31a + 168)/624
Step-by-step explanation:
a/8 - 7(3) = 4a - 78(b)
78b = 4a - a/8 + 21
78b = (32-1)a/8 + 21
78b = (31a + 21(8))/8
78b = (31a + 168)/8
b = (31a + 168)/8 × 1/78
b = (31a + 168)/624
Erik buys 2.5 pounds of cashews.If each pound of cashews cost $7.50, how much will he pay for the cashews
Erik will pay $18.75 for 2.5 pounds of cashews because the price is $7.50 per pound, and the cost is calculated by multiplying the price per pound by the number of pounds.
To calculate how much Erik will pay for 2.5 pounds of cashews at a rate of $7.50 per pound, you simply multiply the number of pounds of cashews by the price per pound.
The formula to determine the cost is: Total Cost = Price per Unit x Quantity.For Erik's purchase, this would be: Total Cost = $7.50 x 2.5.Let's do the calculation:
First, multiply 7.50 by 2.5, which equals 18.75.This means Erik will pay $18.75 for the cashews.There are 4 teams in a soccer tournament. Each team plays each of the other teams exactly once. In each match, the winner receives 3 points and the loser receives 0 points. In the case of a tie, both teams receive 1 point. After all the matches have been played, which of the following total number of points is it impossible for any team to have received?
Answer:
8 points
Step-by-step explanation:
Given that there are 4 teams and Each team plays each of the other teams exactly once, then each team plays 3 matches. The possible points after 3 matches are:
0: 3 lost
1: 2 lost, 1 tied
2: 2 tied, 1 lost
3: 3 tied
4: 1 won, 1 lost, 1 tied
5: 1 won, 2 tied
6: 2 won, 1 lost
7: 2 won, 1 tied
9: 3 won
The answer is 8 points.
Since there are 4 teams in a soccer tournament, and each team plays each of the other teams exactly once, and in each match, the winner receives 3 points and the loser receives 0 points, while in the case of a tie, both teams receive 1 point, to determine, after all the matches have been played, which total number of points is it impossible for any team to have received, the following mathematical logical reasoning must be performed:
0 points = 3 losses = possible 1 point = 1 draw, 2 losses = possible 2 points = 2 draws, 1 loss = possible 3 points = 1 win, 2 losses or 3 draws = possible 4 points = 1 win, 1 draw, 1 loss = possible 5 points = 1 win, 2 draws = possible 6 points = 2 wins, 1 loss = possible 7 points = 2 wins, 1 draw = possible 8 points = impossible, it takes at least 4 matches to achieve that combination 9 points = 3 wins = possible

Help what’s the domain and range
====================================
Explanation:
The left-most point on the graph is at (-3, -5) which is a closed circle. So this point is on the graph. The x coordinate here is x = -3. This is the smallest x value we can plug into the function, so it is the smallest value in the domain.
The upper boundary of the domain is x = 3. We can't actually use 3 itself since there is a open hole at the point (3,-5), meaning that this point isn't part of the graph. We can only get closer and closer to x = 3 but not get there.
So we can say the domain is the set of real numbers x such that [tex]-3 \le x < 3[/tex] meaning that x is between -3 and 3, where we include -3 but exclude 3. To write this in interval notation, you would write [-3, 3)
The square bracket means "include this endpoint". The curved parenthesis means "exclude this endpoint.
-----------
The range is handled in a similar fashion. We look at the y values this time. The smallest y coordinate is y = -5, which is from the point (-3, -5). The largest y value is y = 4 at the point (0,4). We can pick any y value between -5 and 4, including both endpoints, so we say
range = set of all y values such that [tex]-5 \le y \le 4[/tex]
which in interval notation translates to [-5, 4]

suppose that shoes sizes of American women have a bell-shaped distribution with a mean if 8.36 and a standard deviation of 1.49. using the empirical rule, what percentage of American women have shoe sizes that are no more than 3.89
Final answer:
Using the Empirical Rule and the given mean and standard deviation, we find that less than 1% of American women have shoe sizes no more than 3.89.
Explanation:
The student has asked about the percentage of American women who have shoe sizes no more than 3.89, given that the distribution of shoe sizes is bell-shaped, with a mean of 8.36 and a standard deviation of 1.49. Using the Empirical Rule, we know that around 68% of data falls within one standard deviation of the mean, approximately 95% within two standard deviations, and over 99% within three standard deviations.
To find the percentage in this case, we calculate the number of standard deviations 3.89 is from the mean. This number is (8.36 - 3.89) / 1.49 ≈ 3 standard deviations.
Since more than 99% of the distribution lies within three standard deviations from the mean, it is reasonable to infer that more than 99% of American women have shoe sizes larger than 3.89, which means less than 1% will have shoe sizes no more than 3.89.

if xh=10 feet and mxy =100 degrees then determine the arc length of xy
Answer:
The arc length XY is equal to [tex]\frac{50}{9}\pi\ ft[/tex] or [tex]17.4\ ft[/tex]
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the circumference of the circle H
The circumference is given by the formula
[tex]C=2 \pi r[/tex]
we have
[tex]r=xh=10\ ft[/tex]
substitute
[tex]C=2 \pi (10)\\C=20\pi\ ft[/tex]
step 2
we know that
The circumference of a circle subtends a central angle of 360 degrees
so
using proportion
Find out the length of the arc xy if the central angle is equal to 100 degrees
Remember that
[tex]m\angle XHY=arc\ XY=100^o[/tex] ---> by central angle
[tex]\frac{20\pi}{360^o}=\frac{x}{100^o}\\\\x=20\pi(100)/360\\\\x=\frac{2,000}{360}\pi\ ft[/tex]
Simplify
[tex]x=\frac{50}{9}\pi\ ft[/tex] ----> exact value
To find out the approximate value
assume
[tex]\pi=3.14[/tex]
substitute
[tex]x=\frac{50}{9}(3.14)=17.4\ ft[/tex] ----> approximate value
therefore
The arc length XY is equal to [tex]\frac{50}{9}\pi\ ft[/tex] or [tex]17.4\ ft[/tex]
The arc length is 17.4 feet
Arc length of circle:The arc length is given as,
[tex]\theta=\frac{arc}{radius}[/tex]
From given figure, It is observed that radius is 10 feet and angle is 100 degree.
Convert 100 degree into radian,
[tex]100degree=100*\frac{\pi}{180} =1.74 radian[/tex]
Substitute values in above relation.
[tex]1.74=\frac{arc}{10}\\ \\arc=1.74*10=17.4feet[/tex]
Thus, the arc length [tex]xy[/tex] is 17.4 feet
