A circular swimming pool has a radius of 15 feet. What is the circumference of the pool?
Answer: 706.5
Step-by-step explanation:
A= pi r squared
A= 3.14x15 squared
15 squared = 225
A= 3.14x225
Plot and connect the points A (3, -3), B (-3, -2), C (-5, 1), D (-5, 4), E (-4 ,6), F (-2, 6), G (3, 2), and find the length of EF.
Given:
The points are A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2).
To find:
The length of EF and plot each point on a coordinate plane and connect them.
Solution:
Plot the given point A(3, -3), B(-3, -2), C(-5, 1), D(-5, 4), E(-4 ,6), F(-2, 6), G(3, 2) on coordinate plane and connect them as shown in the below figure.
From the below graph it is clear that the length of EF is 2 units. We can verify this solution by using the distance formula.
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, the distance between E(-4 ,6) and F(-2, 6) is
[tex]D=\sqrt{(-2-(-4))^2+(6-6)^2}[/tex]
[tex]D=\sqrt{(-2+4)^2+(0)^2}[/tex]
[tex]D=\sqrt{(2)^2+0}[/tex]
[tex]D=2[/tex]
Therefore, the length of EF is 2 units.

let's one two and three have the following relationships <1and <2 are adjacent right angles <1 and <3 are vertical angles what is the measurement of <1 plus the measure of <3 minus the measure of two
Answer:
180 Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.
how do you solve for x.
Answer:
X=10
Step-by-step explanation:
71+50=121
180-121=59
So (6x-1)=59
(6x-1)=59
+1 +1
6x=60
6x/6=60/6
x=10

____
7 when Y = 87
Answer:
The "first step" is the multiplication of 4 and 87
Step-by-step explanation:
I'll assume that you actually meant 4y + 97. If you substitute 87 for y, you get 4(87) + 97. The "first step" is the multiplication of 4 and 87:
348 + 97, or

Answer:
Equation of the line in point-slope form: y - 5 = -⅚(x - 2)
Equation of the line in slope-intercept form: y = -⅚x + 20/3
Step-by-step explanation:
Equation of a line can be expressed in the point-slope form as y - b = m(x - a), where,
m = slope = -⅚
a = 2
b = 5
Substitute the values into y - b = m(x - a):
y - 5 = -⅚(x - 2) => point-slope form.
We can rewrite this in the slope-intercept form, such as:
Multiply both sides by 6
6(y - 5) = -5(x - 2)
6y - 30 = -5x + 10
6y - 30 + 30 = -5x + 10 + 30
6y = -5x + 40
Divide both sides by 6
y = -5x/6 + 40/6
y = -⅚x + 20/3

Você precisa colocar suas renas, Raposa, Trovão, Cometa e Relâmpago, em uma fila única para puxar o seu trenó. No entanto, Cometa e Raposa são melhores amigos e precisam ficar juntos. De quantas maneiras você pode organizar as renas?
Answer:
If the reindeer do not fight, there are 5!=120 ways to line them up in a straight line.
Out of these, Bloopin and Rudy are together in 4!=24 times. Similarly Rudy and Bloopin will be together 4!=24 times. So the number of ways they are not together is 120-24-24=72 ways.
Hope this helps. :)
Step-by-step explanation:
Spanish:
Si los renos no luchan, hay 5! = 120 formas de alinearlos en línea recta.
De estos, Bloopin y Rudy están juntos en 4! = 24 veces. De manera similar, Rudy y Bloopin estarán juntos 4! = 24 veces. Entonces, el número de formas en que no están juntas es 120-24-24 = 72 formas.
Espero que esto ayude :)

Although it is now extinct, the Carolina parakeet was last seen in Florida in 1920. Back then, large areas of habitat were logged and converted to agricultural fields. Honeybees evicted the parakeets from hollow trees where they nested. Many parakeets were shot for food and their feathers. In addition, farmers shot the parakeets to keep them from eating their seeds. What can you conclude from these observations about why the Carolina parakeet became extinct?
a.Extinction may be the result of several factors.
b.Extinction is always the result of human activity.
c.Extinction occurs when an organism adapts to changes in its environment.
d.Extinction can be reversed if conservation measures are immediately put in place.

Step-by-step explanation:
Here is an expression: 2 + 3ⁱ ( Remember what you do when you replace i with a number) Evaluate the expression when i is 1.
Answer:
The value of the expression when i is 1 is equals to 5.
Step-by-step explanation:
We are given the following expression:
[tex]2 + 3^{i}[/tex]
Evaluate the expression when i is 1.
We replace i by 1. When we elevate a number to the 1, the result is the number we elevate. So
[tex]2 + 3^{i} = 2 + 3^{1} = 2 + 3 = 5[/tex]
The value of the expression when i is 1 is equals to 5.

Answer:
B) 50
Step-by-step explanation:
<A = x + 53
x + 53 + x + 83 + 50 = 180
2x + 186 = 180
2x = -6
x = -3
<A = x + 53
-3 + 53

Elena would like to know the average height of seventh graders in her school district. She measures the heights of everyone in a random sample of 20 students. The mean height of Elena's sample is 58 inches, and the MAD (mean absolute deviation) is 3 inches. Select all the true statements. The mean height of all seventh graders is likely be between 52 and 64 inches. Another random sample of 20 students will always have a mean of 58 inches. A sample of 20 female students would be more likely to get an accurate estimate of the mean height of the population than a sample of a mix of 20 male and female students. m A sample of 100 seventh graders would be more likely to get an accurate estimate of the mean height of the population than a sample of 20 seventh graders. a Elena's sample proves that half of all seventh graders are taller than 58 inches.
Answer:
A. The median height of the sample must be between 59 and 63 inches.
B. Another random sample of 20 students is likely to have a mean between 57 and 65 inches.
E. Elena would be more likely to get an accurate estimate of the mean height of the population by sampling 40 people instead of sampling 20 people.
Step-by-step explanation:
The mean absolute deviation shows the variation in a given data set. It can be determined by calculating the mean of the absolute value of the initial mean and each data set. It describes how spread out the data set are.
With respect to Elena's sampling, the mean absolute deviation is 2. This shows that there is little variation among the data set.
The estimate becomes more accurate if she increase the sample size. Thus options A, B and E are appropriate.

f(50) = 2500 + 89
f(50) = 2589
What is the GCF of the numerator & denominator below?
(x-2)(x+3)/x^2+4x+3
Answer:
Step-by-step explanation:
Factorize the denominator
Sum = 4
Product = 3
Factors = 1 , 3 {1*3 = 3 and 1+3 = 4}
x² + 4x + 3 = x² + x + 3x + 1*3
= x(x + 1) + 3(x + 1)
= (x + 1)(x + 3)
GCF of the numerator and denominator = (x + 3)
