Answer:
D. 79%
Step-by-step explanation:
Took the the on USA Test prep
If a point is randomly selected from the rectangular area of the graph, the probability that it will be in the blue region is 79%.
What is the probability?The ratio of the number of favorable outcomes to the total number of outcomes of an event is known as probability.
It is given that, the length=20, the width=10, and the radius of half circle=10.
Calculate the area of the rectangle.
Knows the area of the rectangle is the product of length and width.
So,
[tex]\Rightarrow \text{Area of rectangle}=\text{10}\times \text{20} \\ \Rightarrow \text{Area of rectangle}=200 \\[/tex]
Calculate the area of the half-circle.
Knows the area of the half-circle[tex]=\frac{\pi r^{2} }{2}[/tex].
So,
[tex]& \Rightarrow \text{Area of half circle}=\frac{3.14\times 10\times 10}{2} \\ & \Rightarrow \text{Area of half circle}=\frac{314}{2} \\ & \Rightarrow \text{Area of half circle}=157 \\[/tex]
Calculate the probability that it will be in the blue region.
Knows the formula for the probability, [tex]\text{Probability}\left( \text{Event} \right)=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}[/tex]
So,
[tex]& \Rightarrow \text{Probability}=\frac{\text{157}}{200} \\ & \Rightarrow \text{Probability}=0.78539 \\ & \therefore \text{Probability }\%=79\% \\[/tex]
Thus, the correct answer is an option (D). i.e., 79%.

Answer:
1) x + 4 = 11
Subtract 4 on both sides, to get x = 7 .
2) x + 3 = 24
Subtract 3 on both sides, to get x = 21 .
3) 4x = 12
Divide 4 on both sides, to get x = 3 .
4) 5x + 3 = 33
First subtract 3 on both sides to get
5x = 30, now divide 5 on both sides, to
get x = 6 .
5) 8x + 5 = 3x + 20
First subtract 5 from 20 in order to
move it, now you have 8x = 3x + 15 .
Next subtract 3x from 8x in order to
move it, now you have 5x = 15 . Lastly
divide 5 on both sides, to get x = 3 .
1) 1/2 x = 4
Multiply both sides by 2, to get 1x = 8,
or x = 8 .
2) 4/3 x = 4
Multiply both sides by 3, to get 4x = 12 .
Next divide 4 on both sides to get
x = 3 .
3) 2x + (-4) = 8
Add 4 on both sides, to get 2x = 12 .
Next divide 2 on both sides to get
x = 6 .
4) 1/3 x + 1/2 x = 20
First multiply the denominators to get a
common denominator of 6 and then
add 3 and 2, to get the numerator. Now
you have 5/6 x = 20 . Next multiply 6
on both sides to get 5x = 120 . Lastly
divide 5 on both sides to get x = 24 .
5) 1/3 x = 1/5 x + 10
First multiply the denominator to get a
common denominator of 15 and then
subtract 3 from 5 to get the numerator.
Now you have 2/15 x = 10 . Next
multiply 15 on both sides to get
2x = 150. Lastly divide 2 on both sides
to get x = 75 .

In a circle of radius 1, what is the length of an arc cut off by a central angle of 2 radians?
Answer:
What is the length of an arc cut off?
If θ (in radians) is a central angle in a circle with radius r, then the length of the arc cut off by θ is given by s = r θ (θ is in radians).
Step-by-step explanation:
Length of an Arc = θ × r, where θ is in radian.
Length of an Arc = θ × (π/180) × r, where θ is in degree.

The line y=−0.5x+b passes through the points (1,5.5), (3,p), (4,4), and (7,n). Find b, n, and p.
Step-by-step explanation:
Finding b
If we use the given slope and use one of the points to write the equation in point-slope form (y - y₁) = m(x - x₁)), we can rearrange it to find the y-intercept:
Using (4,4)
⇒ y - 4 = - 0.5 (x - 4)
y - 4 = - 0.5 x + 2
y = -0.5 x + 6
∴ b = 6Calculating 'n' and 'p'
We can find n and p by plugging the points into the newly found equation y = -0.5 x + 6.
For n using (7, n)
since y = -0.5 x + 6
n = -0.5 (7) + 6
∴ n = 2.5For p using (3,p)
since y = -0.5 x + 6
p = - 0.5 (3) + 6
p = - 1.5 + 6
p = 4.5Checking the answer
We can check the answer we got in two ways:
We could also have found n a different way:Using the points (4, 4) and (7, n) as (x₁, y₁) & (x₂, y₂) respectively
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
- 0.5 = (n - 4) ÷ (7 - 4)
- 0.5 = ⁿ⁻⁴/₃ [multiply both sides by 3]
- 1.5 = n - 4 [add four to both sides]
n = 2.5 [this matches the value of n we found]
We can plot the line and see if it goes through the points we found. As seen in the graph below, the line passes through all the points.

If a rhombus is inside a regular hexagon, what is the size of x
Answer: x = 60°
Step-by-step explanation:
The rest of the question is the attached figure.
Given: A rhombus inside a regular hexagon, work out the angle x.
As shown
ABCDEF is a regular hexagon.
The regular hexagon have 6 congruent angles, and the sum of the interior angles is 720°
So, the measure of one angle of the regular hexagon = 720/6 = 120°
So, ∠F = ∠BAF = 120°
AFEG is a rhombus.
The rhombus have 2 obtuse angles and 2 acute angles.
∠F is one of the obtuse angles of the rhombus = 120°
∠F and ∠FA G are supplementary angles
So, ∠F + ∠FA G = 180°
∴ ∠FA G = 180° - ∠F = 180 - 120 = 60°
∴ x = ∠GAB = ∠BAF - ∠FA G = 120 - 60 = 60°
So, the measure of the angle x = 60°

dani takes her two friends out for lunch. dani's meal costs $5. 72 and her friends' meal are $4. 89 and $7. 30. dani pays for the meals with a $20 dollar bill. how much change should she get?
Your answer is : $2.09
To find this answer you first need to find out how much money Dani spend.The equation for this is (5.72+4.89+7.30=17.91).The last step is to subtract the amount Dani spent by the amount she paid so new equation is (20.00-17.91=2.09)The answer is $2.09
