The smallest circle in the figure has a radius of 2 inches. Which equation gives the area A of the shaded part of the figure? Recall that A = (pi)r^2
Answers
Answer:
60π in²
Step-by-step explanation:
Inner Circle:
r = 2 in
Area of inner circle = πr²
= π* 2 * 2
= 4π in²
Middle circle:
r = 6 + 2 = 8 in
Area of middle circle = π * 8 * 8
= 64π in²
Area of shaded region = area of middle circle -area of inner circle
= 64π - 4π
= 60π in²
Answer:
A = 60pi
Step-by-step explanation:
the radius of the smallest circle is 2 inches so that would give us an area of 4pi. the distance in the shaded part is 6 inches, since we're wanting to find the area of the shaded part, we'll add the radius of the smallest circle, 2 inches, and add it to the length of the shaded circle, 6 inches, to get a radius of 8 inches. plug 8 inches into the formula and youll get 64pi then subtract the 4pi from 64pi and youll get 60pi, which is the area of the shaded part of a circle.

Step-by-step explanation:
(1, 2)(x, 5) = 1/3
5 - 2 / x - 1 = 1/3
3 / x - 1 = 1/3
x - 1 = 3 / 1/3
x - 1 = 9
x = 9 + 1
x = 10
(5 - 2)/(x - 1) = -3
3 / (x - 1) = -3
So (x - 1) = -1

Find the mean, median, and mode of 14, 15, 3, 15, 14, 14, 18, 15, 8, 16.
Answers
Answer:
mean: 13.2 (average)
median: 14.5 (Center)
mode: 14 and 15 (because data is bimodal so there are two modes
Step-by-step explanation:
Answer:
mean = 13.2, median = 15.5, mode = 18
Step-by-step explanation:
mean = 14+15+3+15+14+14+18+15+8+16/10
= 132/10 = 13.2
median =[ (n/2)th term + (n/2+1)term ]/2
here n is even so this formula is applied and before this is done, the numbers given are to be arranged in ascending or descending order
= [10/2 + (10/2+1)]/2
= [5th term + 6th term]/2
= (15+16)/2
= 31/2 = 15.5
mode = 18

Given the linear function f(x)= - 5/8x + 16, does the point (1,2) lie on the line?
Answers
For a point to lie on the line, you have to be able to plug the x coordinate into the x and the y coordinate into f(x) and the math has to be true. In this case, plug in the x and y and you get 2=-5/8(1) + 16
Simplify the math and the two sides are not equal, therefore that point does not lie on the line. Points that lie on the line are solutions that make the equation true.

a fifth of the sum of number a and 34

Answers
The answer you are looking for is 1/5(a+34).
Solution/Explanation:
"Of"="multiplication (x)."
So, therefore, write it like this, to get the better picture and visualization,
1/5 times the sum of a number "a" and "34."
"Sum" obviously is related to "addition."
So, therefore, we can simplify the algebraic expression a little bit more,
1/5 times (a+34).
Now, we can finally write it like this.
1/5x(a+34).
The more proper way to write it, however is like this:
1/5(a+34).
So, therefore, the final answer is 1/5(a+34).
I hope that this has helped you. Enjoy your day, and take care!
The given statement is required in the form of an algebraic expression.
The statement is a fifth of the sum of number a and 34.

18. Mabel gave Margo a bag containing red, white, and
blue marbles. The bag contained half as many red
marbles as blue ones, and 1/4 of the marbles in the
bag were white. If 8 of the marbles were red, how
many marbles were in the bag?
Answers
So the answer comes out to be 30 marbles in the bag
Answer:
32.
Step-by-step explanation:
Let the number of red marbles be x then the number of blue = 2x
So we have 8 red and 16 blue marbles.
If the total number of marbles are y marbles the number of white one = y/4.
So y = y/4 + 8 + 16
3/4y = 24
y = 24 * 4/3
= 96/3
= 32 marbles.

LCM = 2 × 2 × 2 × 5 × 5
LCM = 200
Answer:
the HCF of 25 and 200 is 25 because it divides both of them and is maximum factor of them.
LCM of 25 and 200 is 200 because it can be divided by both 200 and 25

(a+b+c)^2 - a^2+b^2..................
Answers
Answer:
[tex]2b^2 + c^2 + 2ab + 2ac + 2bc[/tex]
Step-by-step explanation:
Whenever you have a parentheses to a power of a number you have to make it the parentheses times itself, so (a+b+c)^2 becomes (a+b+c)(a+b+c), where you then multiply a by a, a by b, a by c, b by a, b by b, b by c, and so on and then add all those numbers up. If you do that you would get a^2 + ab + ac + ab + b^2 + bc + ac + bc + c^2, where you then add them up to get a^2 + b^2 + c^2 + 2ab + 2ac + 2bc. Since you have - a^2 after this, you cancel out the a^2, and finally, you have + b^2 so you add b^2 to it and you get a final answer of 2b^2 + c^2 + 2ab + 2ac + 2bc.
