A farmer is making a circular pen for her pigs. She needs the pen to have a diameter of 26 feet. If fencing costs $32 per foot, which is the closest to the total cost of the fence that the farmer needs to make the pen?
A) $2894.01
B) $ 2765.19
$ 2612.48
D) $ 2578.94
Answers
Answer:
C
Step-by-step explanation:
circumference= 2* pie*(26/2)
Answer:
[tex]\boxed {\boxed {\sf C. \$ 2612.48 }}[/tex]
Step-by-step explanation:
We are asked to find the cost of the fence a farmer needs to make a pen.
FeetThe fence is used to make a circle. We want to find the cost, but we first need to find how many feet of fence is needed. Essentially, we have to find the perimeter, but this is called the circumference because it is a circle. The formula for calculating circumference is:
[tex]c= \pi d[/tex]
The diameter (d) of the pen is 26 feet and we can use 3.14 for pi. Substitute these values into the formula.
[tex]c=3.14 * 26 \ ft[/tex]
Multiply.
[tex]c= 81.64 \ ft[/tex]
CostThe farmer needs 81.64 feet of fencing. The cost of fencing is $32 per foot, so we multiply the cost by the feet needed.
[tex]\$32 / ft * 81.64 \ ft[/tex]
The units of feet cancel
[tex]\$ 32 * 81.64[/tex]
[tex]\$2612.48[/tex]
The cost of the fencing is $2612.48 and choice C is correct.
bob rewrite the expression 6-(-8) as 6-(+8). Is he correct or incorrect? Explain how you know.
Answers
Answer:
Incorrect
Step-by-step explanation:
When you subtract a negative number it changes it to adding a positive number according to math rules.
6 - (-8) -> 6 + 8
Best of Luck!
Answer:
if Bob rewrite the expression 6-(-8) as 6-(+8) it will be incorrect.
Step-by-step explanation:
If Bob rewrite the expression, 6-(-8) as 6-(+8) he will be incorrect because if he right 6-(-8) as 6-(+8) it will be completely incorrect as if we open the bracket of 6-(-8) it becomes 6+8which is 14 but if we opens open the bracket of 6-(+8) which is -2 and hence simplify will be totally incorrect .Thus,bob should not rewrite the expressions, 6-(-8) as 6-(+8).

C. Find the equation of the line perpendicular to
y = 14x-5 and passing through (2,-3).
Answers
Answer:
y = -1/14x - 20/7
Step-by-step explanation:
An equation consists of y = mx + b.
m = slopeb = y - intercept- When a line is perpendicular, the slope becomes the opposite.
14 = -1/14
- Now, that we have the slope, all we need to do is find the y-intercept/b.
y = -1/14x + b
-3 = -1/14(2) + b
-3 = -1/7 + b
-20/7 = b

The theoretical probability of getting a head when you flip a fair coin is
1
2
, but if a coin was actually flipped 100 times you may not get exactly 50 heads, although it should be close to this amount.
If a coin was flipped a hundred times, the amount of times a head actually did appear would be the relative frequency, so if there were 59 heads and 41 tails the relative frequency of flipping a head would be
59
100
(or 0.59 or 59%).
Relative frequency is used when probability is being estimated using the outcomes of an experiment or trial, when theoretical probability cannot be used.
For example, when using a biased dice, the probability of getting each number is no longer
1
6
. To be able to assign a probability to each number, an experiment would need to be conducted. From the experimental results, the relative frequency could be calculated.
The more times that an experiment has been carried out, the more reliable the relative frequency is as an estimate of the probability.
Example
Ella rolls a dice and records the number of times she scores a six. Find the relative frequency that Ella rolls a six on her dice.

Answer:
127.352.7127.352.7Step-by-step explanation:
Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).
52.7 + x = 180

The price of a cup of coffee has risen to $2.45 today. Yesterday's price was $2.15. Find the percentage increase. Round your answer to the nearest tenth of a percent.
Answers
Answer:
14%
Step-by-step explanation:
To find the percentage change of any two amounts you just need this formula: (new - old) ÷ old
New price = $2.45
Old price = $2.15
2.45 = 2.15 = 0.3
0.3 ÷ 2.15 = 0.139534883721
This would make the percentage increase = %13.9534883721
But the question wants it rounded to the near tenth, so it's %14

The required set of imaginary numbers are, √-1, √-4, √-5. Option A is correct.
To determine from the options the set of imaginary numbers.
A number system is described as a technique of composing to represent digits. It is the mathematical inscription for describing numbers of a given set by using numbers or other characters in a uniform method. It delivers a special presentation of every digit and describes the arithmetic structure.
Here,
imaginary number are the number such square root of negative numbers,
So, the set of imaginary numbers is √-1, √-4, √-5.
While all other set are given are not set of imaginary numbers.
