Find exact radius of circle please help!
===========================================================
Explanation:
Let r be the radius we want to find
The area of the full circle is A = pi*r^2
The unshaded portion is 60 degrees, so the unshaded portion must be 360-60 = 300 degrees.
The full area was pi*r^2, but we only want 300/360 of that full area.
So,
s = shaded area
s = (300/360)*(full circle area)
s = (300/360)*(pi*r^2)
s = 30pi
(300/360)*(pi*r^2) = 30pi
(300/360)*r^2 = 30
(5/6)*r^2 = 30
5r^2 = 30*6
5r^2 = 180
r^2 = 36
r = sqrt(36)
r = 6
The radius is 6 inches.

What is the solution to the system?
1/2x + 3/2= -7
-3x + 2y = -2
Answer: (-2, -4)
Answer:
the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4
Step-by-step explanation:
I presume there is a variable y missing in the first equation, and in fact the system looks like:
(1/2) x + (3/2) y = - 7
- 3 x + 2 y = -2
In such case, we proceed to multiply both sides of tye first equation by 6
6 (1/2) x + 6 (3/2) y = - 42
3 x + 9 y = - 42 and we add term by term this equation to the second one, so as to cancel out the term in x:
3 x + 9 y = - 42
- 3 x + 2 y = -2
_____________
11 y = - 44
divide both sides by 11 to isolate y
y = -44 / 11 = -4
Then with the value y = -4, now we replace it in the second equation to solve for x:
- 3 x + 2 y = - 2
- 3 x + 2 (- 4) = -2
- 3 x - 8 = - 2
add 8 to both sides
- 3 x = 6
divide both sides by (-3) to isolate x
x = 6 / (-3) = - 2
Therefore the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4
Solve this system by substitution, y = 4x + 12. -3x + 2y = 4
Step-by-step explanation:
in equation 1
y=4x+12
so now
eqs 2
2y=4+3x
then
-y=x+8
y= -x-8
so
-x-8=4x+12
-20=5x
-4=x
so
y= 4-8
y=-4

simplify (5 square root 2) * ( 3 square root 2 )
Answer:
30
Step-by-step explanation:
multiply 5 x 3 and you get 15 then multiply the roots and you also get 2 so then you have to multiply 5 and 2 to get 30.
The solution is : the simplification of 5√2 × 3 √2 is: 30.
Here, we have,
given that,
5√2 × 3 √2
now, we need to simplify this, i.e. we have to multiply this.
so, we get,
multiply 5 x 3 and we get 15
then multiply the roots and we also get 2
i.e. √2 ×√2 = 2
so then you have to multiply 15 and 2 to get 30.
i.e. 15 * 2 = 30
so, we have,
5√2 × 3 √2
= 5 × 3 × √2 ×√2
=15 × 2
=30
Hence, The solution is: the simplification of 5√2 × 3 √2 is: 30.

Find all real zeros of the function y=-9x-1
A. -9
B. 1/-9
C. 1/9
D. -9 -1
Please select the best answer from the choices proided
Answer:
OPTION D
Explanation:
For zeros of the function (y is the function, a function of x) we need y = 0 so that in turn means we need - 9x - 1 = 0 or - 9x = 1 (i.e. add 1 to both sides); now divide by - 9, and x = 1/-9 which is exactly the same as - 1/9 or - (1/9) and this is the only zero of the function.
or
If y = -9x - 1,
When y = 0
0 = -9x - 1
0 + 1 = -9x - 1 + 1
1 = -9x
1/9 = -9x/9
1/9 = -x
1/[9 X (-1)] = -x/-1
- (1/9) = x
When x = 0
y = (-9 X 0) - 1
y = 0 - 1
y = - 1
-4x< 8 help please solving one step inequalities
Answer:
x>-2
Step-by-step explanation:
when dividing by a negative number, the inequality sign flips.
Answer:
x > -2
Step-by-step explanation:
-4x< 8 (divide both sides by -4)
-x < 8/4
-x < 2 (divide or multiply both sides by -1, remember to flip the inequality when multiplying or dividing by -1)
x > 2 (-1)

A plane goes from a standstill to 350 mi/hr in about 45 sec. What is the plane's acceleration?
Answer:
The acceleration is 466.7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the plane starts from a standstill
[tex]v = 350mi/h[/tex] -- final velocity
[tex]t = 45s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Convert time to hour
[tex]t = 45s[/tex]
[tex]t = \frac{45}{60}hr[/tex]
[tex]t = 0.75hr[/tex]
Substitute values for v, u and t
[tex]350 = 0 + a*0.75[/tex]
[tex]350 = 0.75a[/tex]
Divide both sides by 0.75
[tex]\frac{350}{0.75} = a[/tex]
[tex]466.67 = a[/tex]
[tex]a=466.67m/s^2[/tex]
Hence, the acceleration is 466.7m/s^2
