Step-by-step explanation:
A rectangular piece of paper with length 35 cm and width 14 cm has two semicircles cut out of it, as shown below.
Find the area of the paper that remains. Use the value 3.14 for it, and do not round your answer. Be sure to include the correct unit
Answer: 336.14 cm²
Step-by-step explanation:
To find the area of the rectangle after being cut, we want to find the area of the two semicircles and subtract it from the area of the rectangle. The area of the rectangle is just base times height, or 35cm times 14cm = 490cm² . Since there are two semicircles with the same diameter, we can just solve for the area of a circle and subtract it. To find the area of the circle, we need the radius, which we get by dividing the diameter by 2. After that, we calculate the radius to be 7cm, squared and multiplied by 3.14 (area of a circle) to get 153.86 cm². Subtract the areas, and we get 490 - 153.86 = 336.14 cm²

what is the mean absolute deviation of the following set 3 1 5 5 2 3 2 3 4 2
Answer:
30-3=27
Step-by-step explanation:
Finding the deviation of this is pretty simple
1) Find the mean
By finding the mean, you add the numbers together, and divide the sum by the number of numbers, in this case there are 10 numbers, so divide by 10
2) Subtract the data value, basically adding all of the numbers up, and subtracting it by 3, the mean.
the number sets:
3,1,5,5,2,3,2,3,4,2
mean=
30/10
by finding this, i added the numbers and divided it by the amount of numbers.
This would equal to 3.
Now, all you have to do is subtract 3 from the data value
The data value is 30, subtracted by 3 would be 27

WORTH 100 POINTS
Answer:
Solution given:
x=2
y=3
The requried solution to the pair of equations is (2, 3).
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Part A: To solve the pair of equations graphically, we need to plot both equations on the same coordinate plane. To plot each equation, we can use the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
For the equation y = 2x - 1, the slope is 2 and the y-intercept is -1. For the equation y = 4x - 5, the slope is 4 and the y-intercept is -5. We can plot these two lines on the same coordinate plane and find their intersection point.
Part B: We can find this point by setting the two equations equal to each other and solving for x:
2x - 1 = 4x - 5
Subtracting 2x from both sides, we get:
-1 = 2x - 5
Adding 5 to both sides, we get:
4 = 2x
Dividing by 2, we get:
x = 2
Now that we have found the value of x, we can substitute it into either equation to find the value of y. Using the equation y = 2x - 1, we get:
y = 2(2) - 1
y = 3
Therefore, the solution to the pair of equations is (2, 3).

Given a bag of 4 red marbles, 5 blue marbles and 6 green marbles, find the probability of
drawing a blue marble and then drawing another blue marble without replacing the first
one.
Please help me!!!
Answer:
Step-by-step explanation:
Probability of drawing a blue marble
= Number of blue Marble/ Total number of marble
= 5 / 4 + 5 + 6
= 5 / 15
= 1/3
Probability of taking another blue marble without replacing the first one
= Number of blue marble - 1 / Total number of marble - 1
= 5 - 1 / 15 - 1
= 4 / 14

James scored the following points per game in the last five basketball
games he played: 31, 20, 27, 19, 28. Find the mean absolute deviation of the
number of points scored. *
A. 4.4
B. 6.2
C. 25
D. 125
The mean absolute deviation of the number of points scored is 4.4.
What is Mean Deviation?The mean deviation is used to calculate how far the values fall from the mean of the data set.
Here, Given data is 31, 20, 27, 19, 28
Mean = Sum of all data / number of terms
= (31 + 20 + 27 + 19 + 28)/5
= 125/5
= 25
Then, the deviation will be 6, 5, 2, 6, 3
Mean Deviation = Sum of Deviation / Total number of deviation
= ( 6 + 5 + 2 + 6 + 3) / 5
= 22 / 5
= 4.4
Thus, the mean absolute deviation of the number of points scored is 4.4.

Focus on triangle QAC. We're given that CQ = CA, which in turn means the angles opposite these sides (angles A and Q in that order) are congruent. This is one property of isosceles triangles. Let's make x equal to each of these angles.
With inscribed angle QAC = x, it doubles to 2x which is the measure of minor arc BC (inscribed angle theorem). Minor arc AB is also 2x, since we're told these two arcs have the same measure.
If minor arc BC = 2x, then cutting this in half leads to x again, which points to inscribed angle BDC equal to x. Notice how inscribed angles QAC and BDC subtend the same minor arc BC. Through similar logic, inscribed angle BDA is also x.
In short: angle BDC = angle BDA = x. This leads to angle ADC = 2x. We'll use this later.
-------------------
Let's go back to triangle QAC. The angles A and Q are both x each. The missing angle C is...
Q+A+C = 180
x+x+C = 180
2x+C = 180
C = 180-2x
Making angle QCA equal to 180-2x
Angle ACD is supplementary to this.
So,
angle ACD = 180-(angle QCA) = 180-(180-2x) = 2x. We'll use this later as well.
---------------------
The first section concluded with angle ADC = 2x, while the second section concluded with angle ACD = 2x
For triangle ACD, the bottom angles C and D are both 2x. This is sufficient evidence to show that triangle ACD is isosceles. Furthermore, it means AC = AD, which are the sides opposite angles D and C respectively.
If a,b,c are all non-zero numbers and a+b+c=0, prove that
[tex]a ^{2} / bc + b²/ac + c²/ab = 3[/tex]
no spam and kindly explain your answer!
Given - a+b+c = 0
To prove that-
a²/bc + b²/ac + c²/ab = 3
Now we know that
when x+y+z = 0,
then x³+y³+z³ = 3xyz
that means
(x³+y³+z³)/xyz = 3 ---- eq 1)
Lets solve for LHS
LHS = a²/bc + b²/ac + c²/ab
we can write it as LHS = a³/abc + b³/abc + c³/abc
by multiplying missing denominators,
now take common abc from denominator and you'll get,
LHS = (a³+b³+c³)/abc --- eq (2)
Comparing one and two we can say that
(a³+b³+c³)/abc = 3
Hence proved,
a²/bc + b²/ac + c²/ab = 3

Solve for x please help !!!!!!!
Answer:
x ≈ 20.31
Step-by-step explanation:
By applying tangent rule in the given right triangle,
tan(55°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
Measure of the opposite side = 29 units
Measure of the adjacent side = x
Substitute these values in the expression,
tan(55) = [tex]\frac{29}{x}[/tex]
x = [tex]\frac{29}{tan(55)}[/tex]
x = 20.306
x ≈ 20.31
The diameter of a circle is 4 yards. What is the circle's area?
Use 3.14 for n.
square yards
Area of a circle formula: area = pi x r^2
R is the radius which is 1/2 the diameter.
The diameter is 4 yards so the radius is 4/2 = 2 yards.
Area = 3.14 x 2^2
Area = 12.56 square yards.
According to the graph, what is the value of the constant in the equation
below?
Answer:
The value of the constant in the equation below is 20.
Step-by-step explanation:
You are given the formula height = constant/width. All you have to do is take one of the points given on the graph and plug it in to the formula.
Example:
1 = Constant/20
Constant = 20
As per linear equation, the Constant in the given graph is 20.
What is a linear equation?A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.
Here, Height = Constant/Width
Therefore, Constant = Height × Width
We can take any two random points given on the graph.
Two points are (5, 4) and (20, 1).
For the first point,
Height = 4, Width = 5.
Therefore, Constant = 4 × 5 = 20
For the second point,
Height = 1, Width = 20.
Therefore, Constant = 1 × 20 = 20
Therefore, Constant in the given graph is 20.
