Answer:
So our answer in pi form is 30.25π
Step-by-step explanation:
The circumference of a circle is given by the formulas :
[tex]2\pi r[/tex] or [tex]\pi d[/tex] where r is radius and d is the diameter
Since
11π = 2πr
We can solve for r to use it in the area of a circle formula:
[tex]\frac{11\pi }{2\pi } = r[/tex]
r = 5.5
The area of a circle is given by the formula:
[tex]\pi r^{2}[/tex] where r is the radius/.
Since we found r we can find the area:
π(5.5)² = 30.25π
So our answer in pi form is 30.25π
Answer:
As you have not specified the format in which to give the answer, I am giving three ways of writing it:
[tex]\sf 30.25 \pi \ units^2[/tex]
[tex]\sf \dfrac{121}{4} \pi \ units^2[/tex]
95.03 units² (nearest hundredth)
Step-by-step explanation:
Formulae
Circumference of a circle = 2πrArea of a circle = πr²(where r is the radius)
Given:
circumference = 11πTherefore, use the given value and the circumference equation to find the radius:
⇒ circumference = 11π
⇒ 2πr = 11π
⇒ 2r = 11
⇒ r = 5.5
Now we have found the radius, simply substitute this into the equation for area of circle:
⇒ area of a circle = πr²
= π5.5²
= 30.25π units²

For what value of k will the following linear system have infinitely many solutions?
2a+b=-6, 6a+kb=-18
There are infinitely many solutions to a linear equation with the same variable term on both sides of the equation.
We have to find the coefficient of "b"
from first equation:
2a + b = -6b = -6 - 2afrom second equation:
6a + kb = -18b = (-18 - 6a)/ksolve them simultaneously:
(-18 - 6a)/k = -6 - 2a(-18 - 6a)/(-6 - 2a) = kk = 3WILL CHOOSE BRAINLIEST!!!
To rent a car, company A charges $55 per day and 33 cents per mile. Company B charges no daily fee, but 55 cents per mile. How many miles must you drive for Company B to cost the same as company A?
please show your work
and give the answer
Answer:
about 101 miles to equal the same amount as place A. (if this is daily")
Step-by-step explanation:
so how I went about this is first I added 55+0.33 because thats how much you need to drive one mile for one day with place A. and that equaled 50.30 so then I divided 50.30 by 0.55 because thats all it costs per mile for place B so I got 100.545454545 so i just rounded it up to 101
i hope im right plmn;)
Answer:
no they are not the same tax or rate because 33 cents off is company B

Can someone help pls.
My goodness, this is rather confusing in the way it is worded. Nevertheless, I will attempt to do what I can. Just please keep in mind that this is my own interpretation of the problem, and therefore could be... incorrect.
I think, to start out, we could set up the problem like so
15 + t ≥ 26
because t is not a set number.
Then all that is needed is to subtract 15 from both sides, and the equation becomes
t ≥ 11
So the resulting answer is t ≥ 11.
I hope that my interpretation helps.

Solve the equation: √x = 3 - (1 / 4)x
Answer:
Let u = √x which gives u2= x and rewrite the given equation in terms of u
u = 3 - u 2 / 4
Multiply all terms by 4, simplify and write the above quadratic in standard form and solve it for u.
u 2 + 4 u - 12 = 0
Two solutions: u = - 6 and u = 2
Use the substitution used above u = √x to solve for x.
u = - 6 = √x has no solution
u = 2 = √x has solution x = 4
Below is shown the graph of the right side of the given equation when written with its right side equal to zero. The x intercept of the graph is the graphical solution to the equation as shown below.
Step-by-step explanation:
Answer: x = 4
Step-by-step explanation:
Given:
√x = 3 - (1 / 4)x
Rewrite:
[tex]\displaystyle \sqrt{x} = 3 - \frac{1}{4}x[/tex]
Square both sides:
[tex]\displaystyle (\sqrt{x} )^{2} = (3 - \frac{1}{4} x)^{2}[/tex]
[tex]\displaystyle x= \frac{1}{16}x^{2} -\frac{3}{2} +9[/tex]
Set the equation equal to 0:
[tex]\displaystyle \frac{-1}{16}x^{2} +\frac{5}{2} -9=0[/tex]
Use the quadratic formula:
[tex]\displaystyle x=\frac{-b\sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]\displaystyle x=\frac{-(\frac{5}{2})\sqrt{(\frac{5}{2})^{2} -4(\frac{-1}{16} )(-9)} }{2(\frac{-1}{16} )}[/tex]
x = 4, 36
Plugging back into equation shows us only one answer works,

Michiko claims that to solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, instead of multiplying the second equation by –2 and then adding the equations, she could multiply the second equation by 2 and then subtract the second equation from the first equation. Which statement is correct?
A: Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations.
B: Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations.
C: Michiko is wrong because her method will give the opposite of the correct value for x for any system of linear equations.
D: Michiko is wrong because her method will give the opposite of the correct value for y for any system of linear equations.
Answer: B) Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations

Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, Michiko suggests multiplying the second equation by 2 and then subtracting the second equation from the first equation.
Multiplying the second equation by 2 gives:
42x + 8y = -26
Now, subtracting the second equation from the first equation gives:
15x + 8y - (42x + 8y) = 1 - (-26)
Simplifying this equation gives:
-27x = 27
Divide both sides by 27
x=-1
we can substitute x = -1 into either of the original equations.
Using the first equation, we get:
15(-1) + 8y = 1
Simplifying this equation gives:
8y = 16
Dividing both sides by 8 gives:
y = 2
Hence, Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

x = 37°

Step-by-step explanation:
To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.
Question 1
[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]
Question 2
To find the bigger arc, subtract the smaller arc from 360°
⇒ 360° - 140° = 220°
[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]
Question 3
The smaller arc can also be found by subtracting the external angle from 180°
Smaller arc = 180° - 80° = 100°
[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]
[tex]160^{\circ}=x-100^{\circ}[/tex]

3. Surface Area = 300 yd^2
Step-by-step explanation:
2.
Surface Area of Prism Formula:
Triangle Formula: Area = 1/2 * Base * Height
Left Triangle: Area = 1/2 * 8m * 6m = 1/2 * 48 = 24 m^2
Right Triangle: Area = 24m^2
Rectangle Formula: Area = Length * Width
Top Rectangle: Area = 22m * 6m = 132m^2
Middle Rectangle: Area = 22m * 8m = 176m^2
Bottom Rectangle: Area = 22m * 10m = 220m^2
Add Total Surface Area:
Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect
Surface Area = 24 + 24 + 132 + 176 + 220
Surface Area = 576 m^2

Answer:
C. 1/5 divide by 4
Step-by-step explanation:
When you divide two fractions, you multiply the first fraction by the reciprocal of the other one. To find the reciprocal of the second fraction, yo just have to switch the value of the numerator and denominator (i.e. 4/1's reciprocal is 1/4).
Another important thing to note is that 1/5 x 1/4 is 1/20 because you multiply straight across numerators and denominators.
