9 cm
Step-by-step explanation:
Arc length = θ/360 × 2πr
A circle has an arc with a measure of 120 degrees and a lenght of 3π cm. What is the diameter of the circle
Hence,
3π = 120/360 × 2πr
Diameter = 2r
3π = 1/3 × 2πr
Cross Multiply
9π = 2πr
2r = 9π/π
Note that :
Diameter = 2r
Hence,
Diameter = 9 cm

Step-by-step explanation:
So basically, there are 4 segments: 15-30, 30-45, 45-60, 60-75.
There is also a list of values.
If these values fall between 15-30, for example, it is considered a freqeuncy of 1.
If a second value also falls between 15-30, it is considered to then have a frequency of 2.
Every value that falls under a range of values, such as 15-30, is counted as a freqeuncy of 1.
So, lets look at 15-30.
There is a freqeuncy of 3.
This means that 3 values were in between 15 and 30,
Now, we need to know how many values were above 30.
This means we do not count values that are in the 15-30 segment.
However, we do want to look at the freqeuncy in 30-45, 45-60, and 60-75.
In 30-45 we have a frequency of 3.
In 45-60 we have a frequency of 2.
In 60-75 we have a frequency of 2.
To find the amount of values above 30, we must add these all together:
3+2+2
=
7
So 7 values have a price above 30!
Hope this helps!

The ratio of two radii of two spheres is 15:8. If the surface area of larger sphere is 706.9 mm2, fine the surface area of the smaller sphere.
Answer:
201.1 mm²
Step-by-step explanation:
Smaller sphere = 8
Larger sphere = 15
Larger sphere surface area = 706.9 mm²
Smaller sphere surface area = x
Hence:
Since we are dealing with surface area
8²/15² = x/ 706.9
Cross Multiply
15² × x = 706.9 × 8²
x = 706.9 × 8²/15²
x = 201.07377778 mm²
x ≈ 201.1 mm²
Therefore, the surface area of the smaller sphere is 201.1 mm²

Step-by-step explanation:
I made some brownies and cookies to sell for a local fundraiser. The cookies sold for $0.75 each and the brownies sold for $1.25 each. If I sold 51 baked goods and made $53.25 from the bake sale, which item’s sales made the most money? Cookies Brownies
Answer:
Brownies made the most money
Step-by-step explanation:
Let c = cookies
b = brownies
We sold 51 items so c+b = 51
Cookies are .75 and brownies are 1.25
.75c + 1.25 b = 53.25
We have 2 equations and 2 unknowns
c = 51-b
Substituting into the second equation
.75(51-b) + 1.25b = 53.25
Distribute
38.25-.75b +1.25b = 53.25
Combine like terms
38.25+.5b = 53.25
Subtract 38.25 from each side
38.25 +.5b -38.25 = 53.25 -38.25
.5b =15
Divide each side by .5
.5b/.5 = 15/.5
b = 30
Now find c
c =51-b
c = 51-30
c = 21
They sold 30 brownies and 21 cookies
30 brownies * 1.25 =37.50
21 cookies *.75 = 15.75
Brownies made the most money

What is the value of x?
K
83°
L
M
(9x + 40)
Answer:
This inscribed angle is half of the intercepted arc JL, so 2(83)= 9x +40.
166 -40 = 9x, x=14.
Step-by-step explanation:
The value of x in the given figure is 14 which we obtain by inscribed angle is half of the intercepted arc.
The inscribed angle is half of the intercepted arc.
83 = 1/2(9x+40)
Now let us find the value for x
83= 9/2x + 20
Subtract 20 from both sides to isolate the x variable
83-20=9/2x
63=9/2x
126=9x
Divide both sides by 9
14 is value of x
x=14

A fair die is rolled once. Let A be the event of rolling an even number, and let B be the event of rolling a number greater than 3. Find A ∩ B
Answer:
A ∩ B = {4, 6}
Step-by-step explanation:
A die had 6 faces
S = {1, 2, 3, 4, 5, 6}
If A be the event of rolling an even number, then;
A = {2, 4, 6}
If B be the event of rolling a number greater than 3, then;
B = {4, 5, 6}
A ∩ B are the values that are common to both sets
A ∩ B = {4, 6}

What is the volume of a hollow ball whose other radius is 200m and inner radius of 100m? What is the mass if it is iron?
Solution :
Volume of ball = Volume of outer ball - Volume of inner ball
[tex]V = \dfrac{4\pi R^3}{3} - \dfrac{4 \pi r^3}{3}\\\\V = \dfrac{4\pi}{3}( R^3 - r^3 )\\\\V = \dfrac{4\pi}{3}( 200^3 - 100^3 )\\\\V = \dfrac{4\pi}{3}(2^3 - 1^3) \times 10^6\\\\V = 2.93 \times 10^7 \ m^3[/tex]
Now, density of iron is, d = 7300 kg/m³.
So, mass of iron ball is :
[tex]m = d\times V\\\\m = 7300\times 2.93 \times 10^7 \ kg\\\\m = 2.14 \times 10^{11}\ kg[/tex]
Hence, this is the required solution.

The slope of the line below is -4. Write the equation of the line in point-slope
form, using the coordinates of the labeled point. Do not use parenthesis on
the y-side.
(-2, 2)
Answer:
y - 2 = - 4(x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 4 and (a, b) = (- 2, 2 ) , then
y - 2 = - 4(x - (- 2) ) , that is
y - 2 = - 4(x + 2)
