Explanation:
The radius of the larger circle is CB = CA+AB = 8+3 = 11 inches.
The area of the larger circle with this radius is...
A = pi*r^2
A = pi*11^2
A = 121pi
The area of the smaller circle (radius CA = 8 inches) is
A = pi*r^2
A = pi*8^2
A = 64pi
The difference is 121pi-64pi = 57pi
This represents the exact area of the full ring. Refer to figure 1 below. Specifically the red region of that figure.
However, we don't want the full ring. We only want a small fraction of it (as figure 2 shows, which is the original diagram your teacher gave you). Specifically, we want (4*30)/360 = 120/360 = 1/3 of the full ring. The 4*30 refers to the idea we have four copies of the 30 degree angle.
So we'll take 1/3 of the 57pi to get (1/3)*57pi = (57/3)pi = 19pi
-----------------------------------
The value 19pi is the exact area of the entire shaded region.
From here, you can use a calculator to determine that
19pi = 19*3.1415926535898 = 59.6902604182061 which rounds to 59.7
If your teacher insists you use pi = 3.14, then 19*pi = 19*3.14 = 59.66 which also rounds to 59.7

Answer:
2.478 million at the end of 2015
Step-by-step explanation:
Multiply the amount of population at the end of 2012 times 6%
2.1 times 0.06 = 0.126 million
So, at a constant rate, yearly, the population of Dubai increases 0.126 million
2015-2012 = 3
0.126 times 3 = 0.378 million
2.1 + 0.378 = 2.478 million

Apply the distributive property to create an equivalent expression. 12(2a - 6b+ 8) = 2 1 (2a−6b+8)
Answer:
a+4=11b
Step-by-step explanation:
Distributive property in mathematics means to multiply the sum by a number of two or more add-ons will provide the same result that each add-on multiplies by a single number and then together add the products.
for example a( b+c) = ab+ac
Therefore, applying distributive property in asked eapression
12(2a - 6b+ 8) = 21(2a−6b+8)
24a+72b+96 = 42a-126b+168
198b=18a+72
9a +36=99b
3a+12=33b
a+4=11b
The theater sells two types of tickets: adult tickets for $15 and
child tickets for $11.
Last night, the theater sold a total of 147 tickets for a total of
$1889. How many adult tickets did the theater sell last night?
Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets

(NO LINK PLS <3)
Answer:
13
Step-by-step explanation:
To find the range substitute the value of x from the domain into the equation.
x = - 2 : y = -5(- 2) + 3 = 10 + 3 = 13
x = 0 : y = - 5(0) + 3 = 0 + 3 = 3
x = 1 : y = - 5(1) + 3 = - 5 + 3 = - 2
x = 3 : y = - 5(3) + 3 = - 15 + 3 = - 12
range is { - 12, - 2, 3, 13 }
with greatest value in the range being 13

Calculate cos0 to two decimal places. 7 8 Xà A. 0.69 B. -0.14 C. -0.42 OD. -0.07
Correct answer: -0.07
Answer:
D. -0.07 to nearest hundredth.
Step-by-step explanation:
Applying the Cosine Rule:
11^2 = 7^2 + 8^2 - 2*7*8 cos O
cos O = (11^2 - 7^2 - 8^2) / (-2*7*8)
= 8/-112
= -0.07143.
what is the axis of symmetry of the graph of function f(X) = X2 - 10X +16
Answer:
Axis of Symmetry: [tex]x=5[/tex]
Step-by-step explanation:
The axis of symmetry is defined as the line [tex]x=\frac{-b}{2a}[/tex]. Therefore, our axis of symmetry is located at the line [tex]x=\frac{-(-10)}{2(1)}=\frac{10}{2}=5[/tex]. See the graph attached for a visual.
Answer:
x = 5
Step-by-step explanation:
That's f(x) = x^2 - 10x + 16. The coefficients of the x terms are {1, -10, 16}: {a, b, c}.
-b
The formula for the axis of symmetry is x = --------
2a
Here, with a = 1 and b = -10, the formula for this particular axis of symmetry is
-(-10)
x = ------------ = 5
2(1)
or x = 5

Determine whether the lines given by the fallowing equations intersect at (-1/4,3/4) show all work. 4x+8y=5, x-3y= -3
Answer:
(0, 1)
Step-by-step explanation:
First, we need to make y the subject of the formula from both expressions
For 4x+8y=5
8y = 5- 4x
y = (5-4x)/5
Similarly for x-3y= -3
-3y = -3 - x
3y = x+3
y = (x+3)/3
Since both lines intersects, hence;
(5-4x)/5 = (x+3)/3
Cross multiply
5(x+3) = 3(5-4x)
5x + 15 = 15 - 12x
5x + 12x = 15 - 15
17x = 0
x = 0/17
x = 0
Sustitute x = 0 into any of the equations
Given that y = x+3/3
y = 0+3/3
y = 3/3
y = 1
This shows that the lines intesects at (0, 1)
The cost to play the game is $2. The winner gets $6 for making green. Suppose 36 people play the game. How much money will the school take in from this game before giving out prize money? *
Answer:
$72
Step-by-step explanation:
I did 36 x 2. I did not subtract the -6 for the prize money because it says not to.
Answer:
$72
Step-by-step explanation:
You are trying to determine how much money the school will take in before giving out prize money. Knowing this, you can actually ignore the $6 that the winner will get because you are not worried about giving out the prize money yet. You are only worried about how much you will make before the prize money.
So, you can do simple multiplication to find the answer:
price per game * amount of people playing game = money made from games
$2 * 36 = x
$72 = x
