Answer:
C ≈ 251.33
Step-by-step explanation:
The circumference of a circle is C = 2πr
Radius = r = 40 is given in the problem
C = 2* 3.14 * 40
C ≈ 251.33
Answer:
251.2
Step-by-step explanation:
Given,
Radius ( r ) = 40
To find : Circumference of a circle = ?
Formula : -
Circumference of a circle = 2πr
Note : -
The value of π is :
22 / 7 ( in fraction ).3.14 ( in decimal ).Solution : -
Circumference of a circle = 2πr
= 2 x 3.14 x 40
Circumference of a circle = 251.2
Therefore,
Circumference of a circle is 251.2

What would be 3/5 to a mixed number?
Answer: 1 2/3
Step-by-step explanation:
What you end up with, in this case, is 5/3=1 with a remainder of 2. The whole number you came up with (in this case "one") goes in front of the fraction in your answer. To get the fraction part, take the remainder and stick it on top of the denominator (which in this case is 3.) The answer you end up with is 1 2/3.

Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
The time that rocket will hit ground is 8.196 seconds.
What is quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x² (a ≠ 0) for an equation to be a quadratic equation.
Given equation y = -16x² + 121x + 83
let y be the from ground and x be the time,
the time when rocket hit ground y = 0
-16x² + 121x + 83 = 0
solving using quadratic formula
x = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex])/2a
here a = -16, b = 121 and c = 83
[tex]\sqrt{b^{2} - 4ac}[/tex] = [tex]\sqrt{121^{2} - 4(-16)(83) }[/tex]
= [tex]\sqrt{14641 + 5312}[/tex] = 141.25
x = -(-121 + 141.28)/32 = -0.633
x = -(-121 - 141.28)/32
x = 8.196 second
Hence the time is 8.196 seconds.

Jackson has $1.50 in quarters and dimes. Let x represent the number of quarters and y represent the number of dime. Find the domain and range of this situation.
Answer:
3 dimes
Step-by-step explanation:
Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)
Part B: Plug in what you DO know and solve the one you DON’T:
0.10x + 0.25(2) = 0.80
0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:
0.10x = 0.30 (Divide both sides by 0.10)
x = 3

Answer:subtract the numbers in your head.
Step-by-step explanation:
Write the equation of the graph shown below in factored form.
f(x) = (x − 3)2(x + 2)(x − 1)
f(x) = (x + 3)2(x − 2)(x + 1)
f(x) = (x + 3)2(x + 2)(x + 1)
f(x) = (x − 3)2(x − 2)(x − 1)

Answer:
8[tex]\frac{3}{5}[/tex] OR [tex]\frac{43}{5}[/tex]
Step-by-step explanation:
The total amount of rice that the chef bought is 8 6/10
The chef brought 3/2 pounds of white rice
The chef also brought 71/10 pounds of brown rice
Therefore the total amount can be calculated as follows
3/2 + 71/10
= 15 + 71/10
= 86/10
= 8 6/10
Hence the total number of rice bought by the chef is 8 6/10

Answer:
[tex]-\frac{41}{36}[/tex]
Step-by-step explanation:
To add or subtract fractions, we need to make their denominators equal. To do so, we find the Least Common Denominator (LCD), then rewrite the fractions in the equation with that denominator.
The LCD of 9 and 12, the denominators, is 36 because [tex]9*4=36[/tex] and [tex]12*3=36[/tex].
Thus:
[tex]-\frac{5*4}{9*4} =-\frac{20}{36}[/tex] and [tex]-\frac{7*3}{12*3} =-\frac{21}{36}[/tex]
Now, add the fractions together.
[tex]-\frac{20}{36} -\frac{21}{36} =-\frac{20+21}{36} =-\frac{41}{36}[/tex]
Thus, the answer is [tex]-\frac{41}{36}[/tex].
