The area of circle can be expressed by the
formula A = ar?where r is a radius of circle.
express radius in terms of area of circle.
9514 1404 393
Answer:
r = √(A/π)
Step-by-step explanation:
Solve for r. Do this by dividing by the coefficient of the r² term, then taking the square root.
A = πr²
A/π = r²
r = √(A/π)

I need an explanation for the problem 4v2=-12v-9. I don't understand why it factors into 4v+3 and 4v+3
Answer:
The factors are [tex]2v+3,2v+3[/tex].
The factors are not [tex]4v+3,4v+3[/tex]
Step-by-step explanation:
Equation is [tex]4v^2=-12v-9[/tex].
This equation can be written as follows:
[tex]4v^2+12v+9=0[/tex]
Here,
[tex]12v=6v+6v[/tex]
Therefore,
[tex]4v^2+6v+6v+9=0\\2v(2v+3)+3(2v+3)=0\\(2v+3)(2v+3)=0[/tex]
So, the factors are [tex]2v+3,2v+3[/tex].
The factors are not [tex]4v+3,4v+3[/tex]

Find the bank discount and proceeds using ordinary interest for a loan to michelle anders for 7,200 at 8.25% annual simple interest from august 8 to november 8
Answer:
$145.5
Step-by-step explanation:
Period, t = August 8.to November 8 = 3 months
Simple interest formula :
A = P(1 + rt)
A = final amount =. 7200
7200 = P(1 + (0.0825 * 3/12))
7200 = P(1 + 0.020625)
7200 = P(1.020625)
7200 = 1.020625P
P = 7200 / 1.020625
P = 7054.5009
Bank discount :
A - P
7200 - 7054.5009
= $145.4991
= $145.5

Actually Welcome to the Concept of the Surface areas and Volumes.
Since, we know that the lateral area of a Right circular cone is given as,
AL = πrl
here, l = slant height , r = radius of the circular base.
so now, we have to find first slant height to get the lateral surface area,
[tex]l \: = \sqrt{ {r}^{2} + {h}^{2} } [/tex]
here, r = 8 cm and h = 15,
hence,
[tex]l \: = \sqrt{64 + 225} = \sqrt{289} = 17cm[/tex]
hence, now we apply the formula,
AL = π(8) (17) cm^2
===> AL = 136 π cm^2

⅕m - 12 = -32
could someone solve this
Answer:
m = -100
Step-by-step explanation:
(1/5)m -12 = -32
add 12 on both sides
(1/5)m = -20
multiply both sides by 5
m = -100
Answer:
m = -100
Step-by-step explanation:
So in order to solve this equation we are going to have to convert 1/5m to a decimal, this will make it easier to solve the equation:
1/5m = 0.2m
Next we are going to take our 0.2m and place it within the equation where 1/5m is:
⅕m - 12 = -32 or 0.2m - 12 = -32
So now we are going to add 12 to both sides of the equal sign in the equation to segregate the 0.2m within the equation:
0.2m - 12 = -32 or 0.2m + (-12 + 12) = (-32 + 12)
making the equation look like this:
0.2m = -20
now we are going to divide 0.2 from both 0.2m and -20 to get the value of m:
0.2m/0.2 = -20/0.2
Thus getting the answer:
m = -100
So how do we know that -100 is the value of m? well we check our work of course by substituting -100 in place of m!
⅕(-100) - 12 = -32 or 0.2(-100) - 12 = 32
0.2(-100) - 12 = 32
-20 - 12 = -32
-32 = -32

15x=12x+15 whats the angle measures.
Answer:
x = 5 (please read the step by step explanation)
Step-by-step explanation:
So, I'm just going to solve for x because the instructions aren't too clear. I believe there is supposed to be an image attached to it, but seeing as I don't have that, I'll just solve for x and you can plug in with the values.
15x = 12x + 15
Same to both sides:
3x = 15
Isolate x:
x = 5
Just plug in those values and you'll be good to go! Have a good day!
How many gallons of a 20% antifreeze solution and a 15% antifreeze solution must be mixed to obtain 30 gal of a 18% antifreeze solution? Round to the nearest gallon
Answer:
20% antifreeze solution = 18 gal
15% antifreeze solution = 12 gal
Step-by-step explanation:
Let
20% antifreeze solution = x
15% antifreeze solution = y
x + y = 30
0.20x + 0.15y = 30 * 0.18
0.20x + 0.15y = 5.4
x + y = 30 (1)
0.20x + 0.15y = 5.4 (2)
From (1)
x = 30 - y
Substitute x = 30 - y into (2)
0.20x + 0.15y = 5.4 (2)
0.20(30 - y) + 0.15y = 5.4
6 - 0.20y + 0.15y = 5.4
- 0.20y + 0.15y = 5.4 - 6
-0.05y = -0.6
y = -0.6/-0.05
y = 12 gal
Substitute y = 12 into (1)
x + y = 30 (1)
x + 12 = 30
x = 30 - 12
x = 18 gal
20% antifreeze solution = 18 gal
15% antifreeze solution = 12 gal
y-2=1/2(x-4) in slope intercept form
Answer:
y = 1/2x
Step-by-step explanation:
y - 2 = 1/2 (x-4)
y = 1/2x - 2 + 2
y = 1/2x
(The y - intercept is 0 because -2 and 2 cancels each other out)
Hope this helps :)
Let me know if there are any mistake!!
The slope intercept form of the equation y - 2 = 1/2 (x - 4) will be
⇒ y = 1/2x
What is equation of line?
The equation of line in slope intercept form is defined as;
y = mx + b
Where, 'm' is slope of line and 'b' is y-intercept.
Given that;
The equation of line is;
y - 2 = 1/2 ( x - 4 )
Now,
We can change the equation of line in slope intercept form as,
y - 2 = 1/2 ( x - 4)
Solve as;
y - 2 = 1/2 x - 1/2 × 4
y - 2 = 1/2 x - 2
Add 2 both side,
y - 2 + 2 = 1/2 x - 2 + 2
y = 1/2 x
Thus, The slope intercept form of the equation y - 2 = 1/2 (x - 4) will be;
⇒ y = 1/2x
