Answer:
[tex]A=379.94\ m^2[/tex]
Step-by-step explanation:
Given that,
The radius of a circl is 11 m
We need to find the area of the circle. The forcemula for the area of a crcle is given by :
[tex]A=\pi r^2[/tex]
Put all the values,
[tex]A=3.14\cdot11^{2}\\A= 379.94\ m^2[/tex]
So, the area of the circle is equal to [tex]379.94\ m^2[/tex].

Is 9/54 equivalent to 1/3
Answer: No.
Step-by-step explanation:
9/54 is equal to 1/6
Answer:
no, it is not
Step-by-step explanation:
9/54 can be simplified by dividing both sides by 3, getting 3/18. you can do this again and get 1/6. significantly smaller that l/3

pls help, no rush I just get really stressed when I don't know the answer to a problem, pls explain ur reasons :)

Answer:
2. correct
3. addition property of equality
4. substitution property of equality
Step-by-step explanation:
You're asked for the Reasons, so you need to examine the Statements to see how you get from one line to the next.
The first line of Statement 2 differs from Statement 3 in that m∠GHI has been added to both sides of the equation (ignoring the typo in statement 3). The reason you can add the same thing to both sides of an equation is given by the Addition Property of Equality.
Statement 3 differs from Statement 4 in that one of the m∠GHI has been replaced by m∠JKL. We can do this replacement because those measures are equal to each other. Replacement of equals by equals is allowed by the Substitution Property of Equality.
Gasoline sells for 1.3 euros per liter. What is the price in US dollars per gallon? (recall that 1 gal = 3.785 L)
British pound is 1.212 to 0.8251 USD
4.67 $/gal is the price of gasoline.
Step-by-step explanation:
Given:
Price of gasoline = 1.3 €/L
1 gallon is equals to 3.785 Liters
1 euros is equals to 0.9497 US dollars
To find:
The price of gasoline in US dollars per gallon
Solution:
Price of the gasoline = 1.3 €/L
[tex]1 gal = 3.785 L\\1L=\frac{1}{3.785} gal\\ 1.3 euro /L=\frac{1.3 euro }{\frac{1}{3.785 }gal}\\=\frac{1.3 euro \times 3.785 }{1 gal}=4.9205 euro /gal[/tex]
Now convert euros to US dollars by using :
1 euros = 0.9497 $
The price of gasoline in US dollar per gallons:
[tex]4.9205 euro/gal=4.9205 \times 0.9497 \$/gal\\=4.6730 \$/gal\approx 4.67 \$/gal[/tex]
4.67 $/gal is the price of gasoline.

give one reason why people loan money from the bank
Step-by-step explanation:
We borrow money because we want to buy something. It may be as large as a property or a car, or something smaller like furniture or a computer. We may borrow money to spend it on experiences. It may be something as large as a loan to travel the world, to something smaller, like using a credit card for a meal out.

What is the domain of y= tan x?
Answer:
π/2 + n*π
Step-by-step explanation:
All real numbers except π/2 + n*π
Answer:
Step-by-step explanation:
For some problems, stating the domain actually means to identify what x CANNOT be as opposed to what x IS. This occurs with tangent and cotangent functions along with rational functions.
As far as the tangent function goes, look at your unit circle. Your unit circle gives you 2 values for each angle, the first value reflects the cosine of the angle and the second value reflects the sine of the angle. This is because cosine is directly related to the x values and sine is directly related to the y values; cos goes into the "x" position and sin goes into the "y" position inside the brackets just like x and y go into parenthesis for coordinates. Anyway, a ratio is undefined if the denominator equals 0, right? And since tangent is the same as sin/cos, tangent is undefined when cos is 0. This occurs at [tex]\frac{\pi}{2}+k\pi[/tex] . That means that tangent does NOT exist at pi over 2 and every integer of pi you add in after. Let's look at a couple of examples of how that domain "works". Adding in an integer means adding in 1, 2, 3, etc. If the domain of tangent is undefined at [tex]\frac{\pi}{2}+k\pi[/tex], then let's let k = 1, and
[tex]\frac{\pi}{2}+1\pi=\frac{\pi}{2}+\frac{2\pi}{2}=\frac{3\pi}{2}[/tex] . Now let k = 2:
[tex]\frac{\pi}{2}+2\pi=\frac{\pi}{2}+\frac{4\pi}{2}=\frac{5\pi}{2}[/tex]. Now let k = 3:
[tex]\frac{\pi}{2}+ 3\pi=\frac{\pi}{2}+\frac{6\pi}{2}=\frac{7\pi}{2}[/tex]. And it continues like that.
You can see when you graph the tangent function in radian mode on your calculator that these values where tangent is undefined show up as asymptotes. Use your unit circle and your graphs to determine the domain of trig functions.

Answer:
9
Step-by-step explanation:
the only thing we can say for sure is that JL is splitting the triangle and also its baseline IK in half.
so, both sides of the baseline must be equal :
3x = x + 6
2x = 6
x = 3
=> LK = x + 6 = 3 + 6 = 9
Find the product of −2+5i and its conjugate. The answer is a+bi where
Answer:
29
Step-by-step explanation:
The given complex number is -2+5i
We need to find the product of −2+5i and its conjugate.
The conjuagate of -2+5i is -2-5i
So, it will become,
[tex](-2+5i)(-2-5i)[/tex]
We know that,
[tex](a-b)(a+b)=a^2-b^2[/tex]
Here, a = -1 and b = 5i
[tex](-2+5i)(-2-5i)=(-2)^2-(5i)^2\\\\=4-25i^2\\\\=4-25(-1)\ \ (As\ i^2=-1)\\\\=4+25\\\\=29[/tex]
So, the values of a+bi is equal to 29.

Dennis collected a total of 1712 stamps over the past 16 years At this rate how many stamps would he collect in 21 years
2,247
Step-by-step explanation:
you take 1712 and divide that by 16 which is 107 and then you multiply 107 by 21 thus you get 2,247.
With a certain medical insurance policy, the customer must first pay an annual $250deductible, and then the policy covers 70% of the cost of x-rays. The first insurance claims for a specific year submitted by a person are for two x-rays. The first x-ray cost $700, and the second x-ray cost $950. How much, in total, will he need to pay for these x-rays?
I got $345, but it's wrong.
Answer:
$495 (745 if you include the $250 deductible)
Step-by-step explanation:
70% of 700 is 490
700 - 490 = 210
70% of 950 is 665
950 - 665 = 285
210 + 285 = $495
Answer:
495
Step-by-step explanation:
70% of 700= 490
700 - 490= 210
70% of 950= 665
950 - 665= 285
Add them together
210 + 285= 495
The reason you might have gotten 345 is because you subtracted 495 with 250 but 250 is how much he has to pay for the medical insurance, not how much he also get off
A researcher wants to calculate the average variability from the mean of the scores in their normally-distributed data set. For each participant, they calculate a deviation score. The researcher then sums all the deviation scores together and is surprised to find that the average deviation from the mean in the group is zero. Which of the statements below is FALSE about this scenario?
A. Deviation scores can be used to calculate sum of squares, variability, and then standard deviation.
B. Approximately the deviation scores will be positive and half will be negative.
C. Deviation scores are calculated by subtracting the participant score from the mean.
D. Average deviation from the mean in the group must be squared to be meaningful.
Answer:
D. Average deviation from the mean in the group must be squared to be meaningful.
Step-by-step explanation:
The average variability from mean is not calculated with mean square of the selected group. The deviation scores calculated by subtracting participant score from the mean.

Which of the following is most likely next in the series?
Answer:
B.
Step-by-step explanation:
Judging by the picture, it appears that you are correct. The pattern seems to go as follows:
1. Blue (with one line)
2. Red (with two lines)
3. Blue (with three lines)
This means that your final step should be red with four lines, and we can eliminate D as there is no sign that the line should branch off that way (based on the pattern that we already have). Hope this helps and please let me know if you still need help!

A metallurgist has one alloy containing 24% aluminum and another containing 60% aluminum. How many pounds of each alloy must he use to make 44 pounds of a third alloy containing 47% aluminum?
Answer:
15 8/9 pounds of 24%
28 1/9pounds of 60%
Step-by-step explanation:
x = pounds of 24%
44 - x = pounds of 60%
24x + 60(44 - x) = 47(44)
24x + 2640 - 60x = 2068
-36x + 2640 = 2068
-36x = -572
x = 15 8/9
44 - x = 28 1/9
Rounded
15 8/9 pounds of 24%
28 1/9pounds of 60%
