Answer:
DR = 10 units
AR = 8.66 units
Step-by-step explanation:
By applying sine rule in the given right triangle,
sin(∠R) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(30°) = [tex]\frac{AD}{DR}[/tex]
[tex]\frac{1}{2}=\frac{5}{DR}[/tex]
DR = 10 units
By applying tangent rule in the given triangle,
tan(∠R) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]tan(30^0)=\frac{AD}{AR}[/tex]
[tex]\frac{1}{\sqrt{3}}=\frac{5}{AR}[/tex]
AR = 5√3
AR = 8.66 units

What is the radius of a hemisphere with a volume of 91358 inº, to the nearest tenth
of an inch?
Answers
Answer:
Calculating for a FULL SPHERE
sphere radius = cube root (.75 * sphere volume / PI)
sphere radius = cube root (.75 * 91,358 / 3.14159265)
sphere radius = 27.9395447176 inches
That's for a FULL SPHERE.
For a HEMISPHERE we divide by two:
13.9697723588
To the nearest tenth of an inch it is
14.0 inches.

Answers
Answer:
Hello! radius is 42.5
Step-by-step explanation:
266.9 ÷ 3.14 = 85 thats the diameter 85 but we want the radius so since we know diameter is twice the radius I divide by 2 to get the radius so 85 ÷ 2 = 42.5 so 42.5 is the radius Hope that helps!

A line passes through the point (12,0) and is parallel to the line with the equation y = 1∕6x + 1. What's the equation of the line?
Answers
Answer:
y=1/6x-2
Step-by-step explanation:
Parralel lines have the same slope.
Since the slope of the parralel equation has to be 1/6, and the point is (12,0)
then you input 12 for x and get 2. But you need to get 0 for y, so the intercept would be negative 2.

Solve
x + y = 100 x -y = 10
Pair of Equation
Answers
lets take
x+y=100 firstly.
then x=100-y equation (i)
Now,
x-y=10
Putting value of x from equation(i)
100-y-y=10
-2y=10-100
-2y=-90
therefore, y=45
Now,
putting value of y in equation(i)
we get
x=100-45
ie x=55
hence, x=55 & y=45
Answer:
The solution is (55, 45).
Step-by-step explanation:
Solve the system of linear equations
x + y = 100
x - y = 10
through elimination by addition / subtraction.
Combining these two equations temporarily eliminates y, leaving us with 2x = 110. Then x = 55.
Substituting 55 for x in the first equation, we get:
55 + y = 100. Subtracting 55 from both sides leaves us with y = 45.
The solution is (55, 45).
