Answers
Answer:
The length of the radius is 2.95 units
The length of the radius of the circle is 2.95 units.
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that blue segment below is a diameter of O
Diameter is five point nine.
We need to find the radius of the given circle.
Radius is equal to diameter by two
Radius= Diameter/2
Now put value of diameter in the above formula
Diameter = 5.9
Radius =5.9/2
=2.95
Hence, the length of the radius of the circle is 2.95 units.

24ft*12 in = 288 inches/36 inches(1yd) = 8yd
120in/12in = 10ft
2yd*36in = 72 in
5yd*36in = 180 in

Which proportion correctly shows the relationship between the part, whole, and percent of a percent problem
Answers
Answer:
C. [tex]\frac{Part}{Whole} =\frac{Percent}{100}[/tex]
Step-by-step explanation:
A good way to think about it is this. You know that 1/2 is 50%. It's common knowledge.
In this case 1 is the Part and 2 is the whole
[tex]\frac{Part}{Whole} = \frac{1}{2} = .50[/tex]
So to get 50% in decimal form we would have to divide it by 100 to move the decimal over two places
[tex]\frac{Percent}{100} = \frac{50}{100} = .50[/tex]
Therfore,
[tex]\frac{1}{2} = \frac{50}{100}[/tex]
or
[tex]\frac{Part}{Whole} =\frac{Percent}{100}[/tex]

Two numbers, x and y, have a sum of 8 and a difference of –14. A. Write a system of equations that can be used to determine the values of x and y. B. Solve the system of equations. Show your work.
Answers
Answer:
The system is:
x + y = 8
x - y = -14
And the solution is:
x = -3
y = 11
Step-by-step explanation:
We have two numbers x and y, such that:
x + y = 8 (the sum is equal to 8)
x - y = -14 (the difference is equal to -14)
This is the system of equations we need to solve.
To solve the system, we first need to isolate one of the variables in one of the equations, I will isolate x in the first equation:
x = 8 - y
Now we can replace this in the other equation to get:
(8 - y) - y = -14
8 - 2*y = -14
8 + 14 = 2*y
22 = 2*y
22/2 = y
11 = y
Now we can replace this in the equation "x = 8 - y"
To get:
x = 8 - 11 = -3
Then the solution to the system is:
x = -3 and y = 11

Step-by-step explanation:
A triangle has two angles that measure 45 degrees and 35 degrees. What is the
measurement of the third angle?
Answers
Well, we know that a triangle's angles add up to 180°, so 45 + 35 + x = 180, and x = 100.
The third angle is 100.
Answer:
The measurement of the third angle is 100 degrees.
Step-by-step explanation:
Just add 45 + 35 which equals to 80. Every triangle's angles equal to 180 degrees so subtract 80 from 180. That equals 100 degrees.
Equation: 45+35=80
180-80=100

A circle is centered on point B. Points A, C and D lie on its circumference.
If ZABC measures 40°, what does ZADC measure?
Answers
Given:
A circle is centered on point B.
Points A, C and D lie on its circumference.
If [tex]m\angle ABC[/tex] measures 40°.
To find:
The [tex]m\angle ADC[/tex].
Solution:
Central angle theorem: According to this theorem, the central angle is equal to the twice of inscribed angle on the same intercepted arc.
In the given figure [tex]\angle ABC[/tex] is the central angle and [tex]m\angle ADC[/tex] is the inscribed angle on the same arc AC.
Using central angle theorem, we get
[tex]m\angle ABC=2m\angle ADC[/tex]
[tex]40^\circ=2m\angle ADC[/tex]
[tex]\dfrac{40^\circ}{2}=m\angle ADC[/tex]
[tex]20^\circ=m\angle ADC[/tex]
Therefore, the measure of angle ADC is 20°.
Find the area of the given shape
Answers
The area of that triangle is 28 square inches.
Explanation:
You must choose a height that is perpendicular to the base.
In that case, the height 8 inches is perpendicular to the base 7 inches.
8 inches x 7 inches= 56 inches.
Since the formula for a triangle is base x height divided by 2, we divided 56 by 2
56 divided by 2 = 28
So the area is 28 square inches

PQ² + 14² = 50²
PQ² + 196 = 2500
PQ² = 2500 - 196 = 2304
PQ = √2304
PQ = 48
Sin Q = [tex]\frac{opposite side}{hypotenuse}=\frac{14}{50}\\[/tex]
[tex]Cos Q = \frac{adjacent side}{hypotenuse}=\frac{48}{50}\\\\Tan Q = \frac{oppsite}{adjacent}=\frac{14}{48}\\\\\\\Sin R = \frac{48}{50}\\\\Cos R = \frac{14}{50}\\\\Tan R = \frac{48}{14}\\\\[/tex]
2) tan 48 = [tex]\frac{x}{17}[/tex]
x = 17 * tan 48 = 17 * 1.1106 = 18.8802
