Answer:
113.115 cm
Step-by-step explanation:
Formula:
C = 2πr
Given:
Radius: 22 cm
Diameter: 44 cm
The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter.
Simply plug in your numbers to find the circumference first.
C = 2π(22)
C = 44π cm or 138.23 cm
Then, divide the circumference in half, and add your diameter.
Perimeter = (44π/2) + 44 = 113.115 cm

In a bag of balls, 3 are yellow, 4 are blue, 6 are green, and 2 are red. Kay
picks 30 balls from the bag, replacing the ball into the bag each time. How
many times would you expect a green ball to be picked?
Answer:
12 marbles
Step-by-step explanation:
First, add the marbles together.
3 + 4 + 6 + 2 = 15
Then, put the 6 in the numerator.
6/15
Next, multiply by 2 to make the denominator 30.
12/30
Kay should expect 12 out of her 30 marbles to be green
Have a wonderful day! :)

What is Graph?
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Quadrilateral RUST has a vertex at R (1,5)
We have to find the coordinates of R after the translation (x,y) of (x+ 1, y - 2)
(1, 5)-->(1+1, 5-2)
Coordinates after translation are (2, 3)
Now by a dilation by a scale factor of 3, centered at the origin
so R'(6, 9)
Hence, (6, 9) are the coordinates of R after the translation (x,y) (x+ 1, y - 2),followed by a dilation by a scale factor of 3,

Hiii dont mind the answer that i put but im not sure if im right, can someone please help me?
Answer:
Option 4
Step-by-step explanation:
The volume of a cylinder is going to be the area of the base (which is a circle) times the height. if you have cylindrical mug, then you can use the base area×height relationship, but it won't be exact because some of the volume is going to be used for the walls of the mug itself.
Anyways:
Volume = Base Area × Height
•Base Area -> Circle = π×radius²
•Height is given as 7in.
Volume = π×(6.2in)² × 7in = 845.33975...
Volume is in units cubed (the 3rd power) which is where the in³ is from. Your closest option here looks to be the 4th choice.

Suppose vanilla beans cost $600 per kilogram. Julie bought 9 grams of vanilla beans. Jacques bought 70 grams of vanilla beans.
How much more did Jacques pay for his vanilla beans?
Answer:
The Correct option is 36.60
Step-by-step explanation:
The key to solving this question lies around measurement conversion,specifically converting grams into its equivalence in kilograms.
1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg
70 grams=0.07 kg
Julie pays=$600*0.009=$5.4
Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-$5.4) than Julie paid
Option is wrong because that was what Julie paid
Option D is wrong because that was what Jacques paid
Option B is obviously wrong

George takes a photograph of a rectangular window that is 312 feet tall and 134 feet wide. He prints the photograph on paper so that the image of the window is 12 foot tall and 14 foot wide. What is the ratio of the area of window to the area of the image of the window?
Answer:
A':A = 1742:7
Step-by-step explanation:
Applying,
A' = L'W'............... Equation 1
Where A' = Area of the window, L' = Length of the window, W' = Width of the window.
From the question,
Given: L' = 312 ft, W' = 134 ft
A' = (312×134)
A' = 41808 ft²
Similarly,
A = LW.................. Equation 2
Where A = Area of the image of the window, L and W is thw length and width of the image of the window
Given: L = 12 ft, W = 14 ft
Therefore,
A = 12×14
A = 168 ft²
Therefore the ratio of A' to A = 41808:168 = 1742:7
A':A = 1742:7

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1800 hours and a standard deviation of 25 hours. Using the empirical rule, what percentage of light bulbs last between 1725 hours and 1875 hours?
Answer:
99.7%
Step-by-step explanation:
The empirical rule formula states that:
68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ
Step 1
We have to find the number of standard deviations from the mean
μ = Mean = 1800 hours
σ = Standard deviation = 25 hours
For 1725 hours
μ - xσ =
1800 - 25x = 1725
25x = 1800 - 1725
25x = 75
x = 75/25
x = 3
For 1875 hours
1800 + 25x = 1875
25x = 1875 - 180
25x = 75
x = 75/25
x = 3
Step 2
From the above calculation, the bum of standard deviations from the mean is 3
Hence, the percentage of light bulbs last between 1725 hours and 1875 hours is 99.7%
Terry rents a kayak while he is on vacation. He is required to pay a deposit of $95 plus an additional $11.50 per day. Terry only has $150 to spend on kayaking. Write and solve an inequality you can use to determine the maximum number of days Terry can afford to rent a kayak.
Answer:
A maximum of 4 days
Step-by-step explanation:
Inequality: 95 + 11.50x ≤ 150
Okay so the 95 is his fee. Then for everyday, it's 11.50 and we don't know how many days yet, so 11.50x. The 95 dollars and the 11.50x has to equal to or less than 150 since that is how much he has to spend on vaca.
95 + 11.50x ≤ 150
-95 -95
11.50x ≤ 55
/11.50 /11.50
X=4.78260869565
You would round down since he has a budget.

Solve w = x + for y.
Reply really fast and give like the work for it too please
Answer:
see below
Step-by-step explanation:
w = x+y/z
Subtract x from each side
w-x = x+y/z -x
w-x = y/z
Multiply each side by z
(w-x) *z = y/z*z
(w-x) *z = y
You can distribute the z if desired
wz -xz = y
Answer:
y = z(w - x)
Step-by-step explanation:
w = x + y/z
Subtract x from both sides
w - x = y/z
Multiply both sides by z
z(w - x) = y
Flip
y = z(w - x)
