Based on the calculations, the circumference of this circle in terms of Pi is equal to [tex]40\pi\;cm[/tex].
How to calculate the circumference of a circle.Mathematically, the circumference of a circle is given by the formula:
[tex]Circumference = 2\pi r[/tex]
Where:
r is the radius of a circle.Given the following data:
Radius of a circle = 75 in.
[tex]\pi = 3.14[/tex]
Substituting the given parameters into the formula, we have;
[tex]Circumference = 2\pi \times 20\\\\Circumference = 40\pi\;cm[/tex]

solve the systems of equations y=2x and y=-x - 6
Answer:
y = -4
x = -2
Step-by-step explanation:
Hi there...
y = 2x
y = -x - 6
Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...
2x = -x - 6
add x on both sides...
3x = -6
divide by 3 on both sides...
x = -2
Now, plug in x for y. Here's what I mean...
y = 2x
y = 2 (-2)
y = -4

A gas station sells 1600 gallons of gasoline per hour if it charges $ 2.70 per gallon but only 900 gallons per hour if it charges $ 2.95
per gallon. Assuming a linear model
(a) How many gallons would be sold per hour of the price is $ 2.90 per gallon?
Answer:
(b) What must the gasoline price be in order to sell 1300 gallons per hour?
Answer:
Answer:
Look just at finding the linear model. Two points. Use price per gallon for x and gallons per hour sold for y. Your two points (x,y) are (2.15,1600) and (2.55,800).
Slope m=%281600-800%29%2F%280.15-0.55%29
m=800%2F0.40
m=2000
Using point-slope form for a line, and the lower-y point,
y-800=2000%28x-2.55%29
highlight%28y=2000%28x-2.55%29%2B800%29

Six Pepperidge Farm bagels were weighed, yielding the following data (grams):
117.6
109.5
111.6
109.2
119.1
110.8
(Note: 4 ounces = 113.4 grams)
a. Assuming that the six bagels are a random sample and the weight is normally distributed, estimate the true average weight and standard deviation of the weight using maximum likelihood.
b. Again assuming a normal distribution, estimate the weight below which 95% of all bagels will have their weights. (Hint: What is the 95th percentile in terms of μ and σ? Now use the invariance principle.)
Answer:
A) Average weight = 112.97
standard deviation = 3.913
B) 119.4069
Step-by-step explanation:
A) Estimate the true average weight and standard deviation of the weight
attached below is a detailed solution
Average weight = 112.97
standard deviation = 3.913
B) Assuming a normal distribution Estimate the weight below

Step-by-step explanation:
Answer:
A. The first option.
Step-by-step explanation:
Using the distributive property you can see that when you distribute them you would get something like (8 x 4) + (3 x 4) = 44. The first option is the only one that states this.

What is BD? please help bru i keep getting trollers
Answer:
BD=13
(This must not be drawn to scale)
Step-by-step explanation:
You have to use the Angle Bisector Theorem to get a ratio.
12/x=27/(x+5)
cross multiply
12(x+5)=27x
12x+60=27x
60=27x-12x
60=15x
60÷15=x
x=4
BD=x+x+5=4+4+5=13
Solve the equation -10(d+1)=-14 I ready, please help ASAP!!
Answer:
d = 0.4
Step-by-step explanation:
-10 (d + 1) = - 14
=> -10d - 10 = -14
=> -10d = -14 + 10
=> -10d = -4
=> 10d = 4
=> d = 4 / 10
=> d = 0.4

ok so the answer for the one after 12x is 8x I think but it would only make sens i dunno the answer to the fraction
Answer and Step-by-step explanation:
Let's solve your equation step-by-step.
−2(x+5)=4
Step 1: Simplify both sides of the equation.
−2(x+5)=4
(−2)(x)+(−2)(5)=4(Distribute)
−2x+−10=4
−2x−10=4
Step 2: Add 10 to both sides.
−2x−10+10=4+10
−2x=14
Step 3: Divide both sides by -2.
-2x/2 = 14/-2
x equals...
x=-7

Answer:
[tex]F = 1.8C + 32[/tex]
Step-by-step explanation:
Given
The attached table
Required
The relationship between both temperatures
This implies that we calculate the table equation
First, we calculate the slope (m)
[tex]m = \frac{F_2 - F_1}{C_2 - C_1}[/tex]
Where:
[tex](C_1,F_1) = (0,32)[/tex]
[tex](C_2,F_2) = (20,68)[/tex]
So, we have:
[tex]m = \frac{68 - 32}{20 - 0}[/tex]
[tex]m = \frac{36}{20}[/tex]
[tex]m = 1.8[/tex]
The equation is then calculated using:
[tex]F = m(C - C_1) + F_1[/tex]
This gives:
[tex]F = 1.8(C - 0) + 32[/tex]
[tex]F = 1.8(C ) + 32[/tex]
[tex]F = 1.8C + 32[/tex]
One number is five less than another. Their sum is fifteen. Find the numbers.
Answer:
THE NUMBERS ARE 10 AND 5
Step-by-step explanation:
LET THE ANOTHER NUMBER BE X THEN
ONE NUMBER = X - 5
BY THE QUESTION
X - 5 + X = 15
2X = 15 + 5
2X = 20
X = 10
X - 5 = 10 - 5 = 5
Answer:
hi 5 and 10 is required no.
let no. be x
another no.be x+5
Step-by-step explanation:
sum=15
x+x+5=15
2x=15-5
2x=10
x=10/2=5
x+5=5+5=10

Write an expression to show k less than 10
Step-by-step explanation:
"Write an expression to show k less than 10"
"less than" means that the number is being subtracted from a different number.
This means that "10" is being subtracted from "k"
Thus,
k - 10 is the appropriate expression for the statement, "k less than 10"
ANSWER: k - 10
Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
20, 10, 5, ...
Answer:
geometric, with a common ratio of 1/2
Step-by-step explanation:
The sequence is geometric because you get successive trems by multiplying the previous term by a certain constant, the 'common ratio'. (If you got each successive term by adding or subtracting the same constant number each time, that would be an arithmetic sequence.)
In this case, it looks like you get each successive term when you multiply the previous term by 1/2.
Thus, the common ratio is 1/2.

There are formulas to solve cubics, but that probably is not the way you are expected to go. Here is a trial and error approach that works in this case.
Assume that the cubic can be factored and that the roots are r1, r2, and r3. Then the factored form is
(x-r1)(x-r2)(x-r3)=0
This shows that the constant must equal the product of the roots.
(r1)(r2)(r3)=-33
One possibility is that the roots are integers. In this case, a factor of 33 might work. Prime factorization of 33 gives 3 and 11. Try 3. Then (x-3) is a factor.
Divide the cubic by (x-3). It works. the result is
x^2+12x+11
This has factors of (x+11) and (x+1). Therefore, the roots are 3, -1, and -11

The ratio of math teachers to choir teachers is 3:2 respectively. There are 12 math teachers. How many math and choir teachers are there all together?
Answer:
Hi liddywiddy, sorry you had to wait so long
There are 20 teachers in all
Step-by-step explanation:
the ratio 3:2 is now 12:x
12 / 3 = 4
so the multiplier is 4
now:
4x2 = 8
Next we add them: 12+ 8 = 20
Answer:
20 teachers in all
Step-by-step explanation:
12 / 3 = 4,
4 * 2 = 8,
so 12 + 8 = 20

Imagine you are hanging two identical picture frames. Each frame is 28 inches wide and the wall you are hanging them on is 10 feet wide. There needs to be 8 inches of space in between the two frames. How far do the frames need to be from the left and right side of the walls in order to be centered?
Answer:
28 inchesStep-by-step explanation:
Sum of the width of the two frames and a gap between them:
28*2 + 8 = 64 inThe gaps from the left and right are equal to x:
x = (10 feet - 64 in)/2 = (120 in - 64 in)/2 = 28 inA convex octagon has interior angles with measures (x + 55). (3x + 20), 4x°. (4x - 10). (6x - 55) (3x + 52). 3.xº, and (2x + 30). Find

You roll a fair six-sided die. The die shows a three or a five.
Answer:
b) 0.333
Step-by-step explanation:
there are 6 options that you can get when you roll a dice. 1, 2, 3, 4, 5, 6. if you want to get a 3 or a 5, that means you want 2/6 possible outcomes. 2/6 is 0.333
A math student has a plan to solve the following system by the elimination method. To eliminate the x-terms, he wants to multiply the top equation by 7. What
should he multiply the second equation by so that when he adds the equations, the x-terms are eliminated?
-3x-7--56
-7x+10y - 1
Answer:
-3
Step-by-step explanation:
7(-3x-7y-56)
-21x-49y-392
-3(-7x+10y-1)
21x-30y+3
because the eq. multiplied by 7 is negative, the second eq mus be positive in order to eliminate the x variable. this is why we multiply by a (-). by multiplying the second eq by 3, both eq. will result in a coefficient of 21. one positive one negative allowing the x variable to be eliminated from the problem.
