Answer:
Step-by-step explanation:
To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.
Answer: [tex]\frac{\pi *r^{2} }{4}[/tex]
Step-by-step explanation: We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle: [tex]\frac{\pi *r^{2} }{4}[/tex]

calculate the range of the data. *
(1 Point)
104, 117, 104, 136, 189, 109, 113, 104
Answer:
The range here is 85
Step-by-step explanation:
Here, we want to calculate the range of the data
Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset
From the given data points, the highest value is 189, while the lowest value is 104
So the range is the difference between the two which is;
189-104 = 85

About Carrier culture initially contains 2500 bacteria and doubles every half hour
Answer:
A bacteria culture initially contains 2500 bacteria and doubles every half hour. The formula for the population is p(t)=2500e^(kt) for some constant k. Find the size of the bacterial population after 100 minutes. Find the size of the bacterial population after 4 hours.
Step-by-step explanation:
Answer:
1. 10000 bacteria
2. 640000 bacteria
Step-by-step explanation:
2500 bacteria: 30 minutes
x bacteria: 60 minutes
The bacteria gets doubled twice
2500*2*2=10000
x bacteria:240 minutes
The bacteria gets doubles 8 times
2500*2*2*2*2*2*2*2*2= 640000

Compare Texas to Carolina. Write the answer in scientific notation. Texas= 2.5x10 to the power of 5. Carolina= 1.2x10 to the power of 3.
Answer:
Texas is 2.08333 * 10^2 times the size of Carolina.
Step-by-step explanation:
Given :
Given that:
Texas= 2.5x10^5
Carolina = 1.2x10^3
Comparing the size of Texas and Carolina
Texas / Carolina
(2.5 * 10^5) ÷ 1.2 * 10^3
(2.5/1.2) * 10^5-3
2.08333 * 10^2
Hence, Texas is 2.08333 * 10^2 times the size of Carolina.

Mohamed wants to buy a television that costs $800, including taxes. To pay for the television, he will use a payment plan that requires him to make a down payment of $200, and then pay $65 each month for 10 months. What is the percent increase from the original cost of the television to the cost of the television using the payment plan?
Answer:
6.25%
Step-by-step explanation:
I'm simply returning the favor.
If the down payment is $200, then we can subtract:
$800 - $200 = $600
Then we can find the "rent" times ten, then subtract it from the $600 left to pay.
$65*10 = $650
Now here is the hard part. We know that 600 < 650. So we need to subtract 650 from 600.
$650 - $600 = $50
Now we need to find how much more Mohamed paid than the original price.
$850 is _____% more than $800.
$850 is 106.25% more than $800.
Subtract 100% to get the difference.
6.25% is your answer.
Hope this helps. Have a nice day.

the graph of g(x) =x -5 is a translation of the graph of the parent function 5 units
Answer:
the answer is: 8(x)= 4 -5
Step-by-step explanation:
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.
The given function is g(x)=x-5.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Here, parent function is g(x) = x
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Shifted down: 5 units
The graph of parent function and translated function are given below. Therefore, the transformation is shifted down 5 units.

The inequality that describes the possible value of x is 2< x < 22.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
Given that ∠A = 50°
AB ≈ DE ≈ EF
BC = 12
CD = 10
And the ∠E = (5x - 10)°
From the Graph, we can see that Angle A is the alternate angle to angle G
Alternate angles are the angles that occur on opposite sides of the transversal line. We can easily spot two interior alternate angles by drawing Z. The value of alternate angles is equal.
thus, ∠A = ∠E
50° = 5x -10
5x = 60
x = 12
Therefore, from the given options the value of x lies in the inequality 2 < x < 22.

Find the measure of the given angles. Show work!!
Answer:
m∠A = 45⁰
m∠B = 75⁰
Step-by-step explanation:
Given question 4;
m∠A = x + 51
m∠B = 81 + x
m∠C = 60⁰
The value of the missing angles can be determined by the finding the value of x first;
m∠A + m∠B + m∠C = 180⁰ (sum of angles in a triangle)
(x + 51) + (81 + x) + 60⁰ = 180
(x + x) + (51 + 81 + 60) = 180
2x + 192 = 180
2x = 180 - 192
2x = -12
x = -12/2
x = -6
Thus, the values of the angles are calculated as follows;
m∠A = x + 51
= -6 + 51
= 45⁰
m∠B = 81 + x
= 81 - 6
= 75⁰

Answer:
Caitlyn's average is roughly 11.4.
Step-by-step explanation:
You get this by dividing 46 by 4, which gets you 11.5.
You then divide 79 by 7, that equals 11.3, rounded.

The measure of an angle is nine times the measure of its complementary angle. What is the measure of each angle?
Answer:
the angle is 81 and it's complementary angle is 9
let X be the angle
let 90-x be it complementary angle
so X=9(90-x)
X=810-9x
810=10x
X=810/10
X=81
and complementary angle 90-x which is 90-81 is equal to 9...

I need help with this equation for math
Answer:
The answer would be B
Step-by-step explanation:
the y-intercept would be a postive 4 and because it's a negative slope, it would rule out all of them except B.
Answer:
y = -1/2x +4
Step-by-step explanation:
We have two points so we can find the slope
m = (y2-y1)/(x2-x1)
= ( 0-4)/(8-0)
= -4/8
= -1/2
We know the y intercept is 4
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -1/2x +4
