Answer:
1332.04
Step-by-step explanation:
C=2πr=2·π·212≈1332.03529
Answer:
1332.035 millimeters
Step-by-step explanation:
If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. You can also work out the circumference of a circle if you know its radius. Remember that the diameter is double the length of the radius. We already know that C = πd. If r is the radius of the circle, then d = 2r. So, C = 2πr.

-15 + t = 60
t=
Answer:
t = 75
Step-by-step explanation:
Step 1: Write equation
-15 + t = 60
Step 2: Solve for t
Add 15 to both sides: t = 75
Step 3: Check
Plug in t to verify it's a solution.
-15 + 75 = 60
60 = 60
Answer:
t= 75
Step-by-step explanation:
15-75=60

For figure ABCDEF shown here, identify the image after a clockwise rotation of 240°, or
counterclockwise rotation of 120°. The naming always begins at the top of the figure and
proceeds clockwise. For example, a reflection across AD has an image of AFEDCB. Drag and
drop each letter into the correct box to identify the image after a clockwise rotation of 240
°, or a counterclockwise rotation of 120°.
Answer:
FABCDE
Step-by-step explanation:
divide 240 by 60 and you get 4 turns
Write and solve an equation and then check your answer. Complete the statements. Graciella divided her grapes equally among 6 friends. If each friend received 16 grapes, how many grapes did Graciella have? The variable, g, represents . The equation that correctly models the problem is . To undo what has been done to the variable, on both sides of the equation. The solution of the equation is . Check the solution by substituting in for g and simplifying.
Answer:
The variable, g, represents
✔ the number of grapes Graciella had
.
The equation that correctly models the problem is
✔ g/6 = 16
.
To undo what has been done to the variable,
✔ multiply by 6
on both sides of the equation.
The solution of the equation is
✔ g = 96
.
Check the solution by substituting
✔ 96
in for g and simplifying.
The solution of the equation will be g = 96.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
The variable, g, represents the total number of grapes that Graciella had.
The equation that correctly models the problem is:
g/6 = 16
To undo what has been done to the variable, we can multiply both sides of the equation by 6:
g = 6 x 16
g = 96
Therefore, Graciella had 96 grapes.
To check the solution, we substitute 96 for g in the original equation:
g/6 = 16
96/6 = 16
16 = 16
The equation is true, so our solution of g = 96 is correct.

You are filling bags with cookies to give your friends. You have 18 chocolate chip cookies and 24 peanut butter cookies. You want identical groups of cookies in each bag with no cookies left over. What is the greatest number of bags you can fill? (Please fill in the blank: Each bag will have _____ cookies.)
Answer:
This means we need 3 chocolate chips and 4 peanut butter in each bag for a total of 7 cookies in each bag
Step-by-step explanation:
Find the prime factors of each number
Chocolate chips 18 = 3*6 = 3 * 2*3
Peanut butter 24 = 4*6 = 2*2*2*3
We want to fill the greatest number of bags so cancel the like factors
Chocolate chips 18 = 3*6 = 3
Peanut butter 24 = 4*6 = 2*2 =4
This means we need 3 chocolate chips and 4 peanut butter in each bag for a total of 7 cookies in each bag
Determine the domain of (f/g)(x) when f(x)=1/x and g(x)= sqrt x+8
(answer choices in photo)
Answer:
(−8,0)∪(0,∞)
Step-by-step explanation:
This is composition, which I'm going to assume you've covered (sorry if I use any weird terms because of that).
So, anyway, (f/g)(x) is basically [tex]\frac{f(x)}{g(x)}[/tex].
In this case, the answer would be [tex]\frac{\frac{1}{x} }{\sqrt{x+8} }[/tex]
I'm going to assume we're using the real number system.
In that case, x can't be less than 0 (can't even be equal to because divide by zero error
So, [tex]\sqrt{x+8} > 0[/tex]
Solve for x by squaring.
[tex]\sqrt{x+8} > 0[/tex]
[tex]x > -8[/tex]
However, in the numerator, there is 1/x. A number divided by 0 is undefined. So, x has to be greater than -8, and it can't be 0.
So, with that, the interval notation is like this.
(−8,0)∪(0,∞)

can someone solve 2x+5=x-1
Answer:
x = -6
Step-by-step explanation:
Answer: x=-6
Step-by-step explanation:
Given
2x+5=x-1
Subtract 5 on both sides
2x+5-5=x-1-5
2x=x-6
Subtract x on both sides
2x-x=x-6-x
x=-6

The sum of two numbers is 68. The second number is 2 more than twice
the first.
Answer:
22 and 46
Step-by-step explanation:
let
one number is x
another is 2x+2
now 2x+2+x=68
or, 3x+2=68
3x=66
or x=66/3=22
so one number is 22 and another is (22X2+2)=46
