In a circle with an 8-inch radius, a central angle has a measure of 60°. How long is the segment joining the endpoints of the arc cut off by the angle?
Answer:
The length of segment joining the endpoints of the arc is [tex]8\ in[/tex]
Step-by-step explanation:
we know that
In the triangle ABC
see the attached figure to better understand the problem
[tex]AC=BC[/tex] -----> is the radius of the circle
[tex]m<CAB=m<CBA[/tex]
[tex]m<ACB=60\°[/tex] ----> given problem (central angle)
Initially the triangle ABC is an isosceles triangle
Remember that
the sum of the internal angles of triangle must be equal to [tex]180\°[/tex]
For this particular case, the isosceles triangle ABC becomes an equilateral triangle, as the three angles are equal to [tex]60\°[/tex]
The equilateral triangle has three equal sides and tree equal angles
so
[tex]AC=BC=AB[/tex]
Hence
The length of segment joining the endpoints of the arc is [tex]8\ in[/tex]
Which of the following values is the 25th percentile?lower quartile, median, upper quartile
Answer:
The value of 25th percentile equals:
lower quartile
Step-by-step explanation:
We have to find the value of the 25th percentile
25th percentile is equal to the lower quartile.
50th percentile is equal to the median.
and 75th percentile is equal to the upper quartile.
Hence, the value of 25th percentile equals:
lower quartile

A surveyor measures the angle of elevation to a point on a mountain to be 18 degrees the point on the mountain is horizontally 4 miles away from the surveyor the vertical change in elevation from the point where the surveyor is standing to the point on the mountain is___ miles?
Answer:
1.3 miles
Step-by-step explanation:
Solution:-
- The surveyor stands at a platform that is B = 4 miles and at an elevation of θ = 18 ° away from the point on the mountain.
- We can construct a right triangle from surveyor to the point of observation. To determine the change in height/elevation (H) we will apply the trigonometric relation as follows:
tan ( θ ) = H / B
- Solve for the elevation (H):
H = B*tan ( θ )
H = 4*tan ( 18 )
H = 1.3 miles
- The change in elevation from surveyor to point of observation is H = 1.3 miles.

Given tan A = .78 find angle A in degrees. Round your answer to the nearest hundredth.
Answer:
[tex]A\approx 37.95^{\circ}[/tex]
Step-by-step explanation:
We have been given that [tex]\text{tan}(A)=0.78[/tex]. We are asked to find measure of angle A in degrees.
We will inverse tangent to find measure of angle A as:
[tex]A=\text{tan}^{-1}(0.78)[/tex]
[tex]A=37.954230875133^{\circ}[/tex]
Upon rounding our answer to nearest hundredth, we will get:
[tex]A\approx 37.95^{\circ}[/tex]
Therefore, the measure of angle A is approximately 37.95 degrees.
The pressure P exerted by a force varies inversely as the area A on which the force is applied. If 16 N/ft2 of pressure is exerted by a force on an area of 3 ft2 , what is the pressure exerted by the same force on an area of 6 ft2?
A) 8 N/ft2
B) 16 N/ft2
C) 4 N/ft2
D) 32 N/ft2
Answer:
A) 8 N/ft2
Step-by-step explanation:
Pressure is the normal force per unit area, that is, it is equivalent to the force acting on the surface unit, and is given by:
[tex]P=\frac{F}{A}[/tex]
Where:
[tex]P=Pressure\\F=Normal\hspace{3}force\\A=Area\hspace{3} where \hspace{3}force\hspace{3} is \hspace{3}applied.[/tex]
In the first case:
[tex]P=16N/ft^2\\A=3ft^2[/tex]
Using the previous equation and solving for [tex]F[/tex] :
[tex]F=P*A=16*3=48N[/tex]
Now, for the second case, since the force is the same applied in the first case, then:
[tex]P=\frac{F}{A} =\frac{48}{6} =8N/ft^2[/tex]
Therefore the answer is:
A) 8 N/ft2

How many kilometers can the prius travel on 16 liters of gasoline?
Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.
It is given that Prius runs on gasoline.
We have to find out that how many kilometers it can run if amount of gasoline is 16 liters.
What will be the value of 16 times of a number x ?
The value will be ; 16 × x .
No. of kilometers Prius travels depends on what is the model of Prius . Also quality of roads makes a difference.
∵ 1 liter = 0.264172 gallons
⇒ 16 liters = 16 × 0.264172 = 4.23 gallons
Let's say a Prius travels x kilometers per gallon.
So ; on 16 liters of gasoline , Prius will travel ;
x × 4.23 = 4.23 × x kilometers
Thus , Prius can travel up to 4.23 × x kilometers on 16 liters of gasoline.

How do you solve 3x+4y=12 and 2x=y-6
3x +4y =12
2x = y-6 Rewrite this as y = 2x+6
now replace that for y in the first equation
3x + 4(2x+6) = 12
now do all the calculations:
3x + 8x +24 =12
11x + 24 = 12
11x = -12
x = -12/11 = -1 1/11
now substitute -12/11 for x in the 2nd equation and solve
y = 2x+6
y = 2(-1 1/11) +6
y = 42/11 = 3 9/11
