True or False: An equation to find Circumference is C = πr2
Answer:
False
Step-by-step explanation:
It's actually C=πd d is diameter or C=πr^2
Answer:
True
Step-by-step explanation: Calculate circumference from area
We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of r to find that r = √13. We find the circumference of the circle with the formula C = 2πr.

x is a positive integer.
33 = x is a positive integer.
Work out the four possible values of x, writing your values in ascending order.
Answer:
Four possible values of x: 10, 3, 20, 31
Writing it in ascending order : 3, 10, 20, 31, 33
Step-by-step explanation:
Because x is a positive integers it means that x could be any number that goes from zero to infinity.
The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33.
What is an integer?An integer is a whole number irrespective of the sign that the integer is all whole numbers that are going from 0 to infinite or 0 to minus infinite.
Integer ; ....-2 , -1 , 0 , 1 , 2 , .....
Given the expression, 33/x
Now positive integers are whole numbers ( 1,2,3,...)
To 33/x be the whole number and x is also a positive integer.
33/1 = 33 (1,3 Positive integer)
33/3 = 11 (3,11 Positive integer)
33/11 = 3 (11,3 Positive integer)
33/33 = 1 (33,1 Positive integer)
Hence "The possible values of x such that 33/x remains a positive integer in ascending order are 1,3,11 and 33".

Kayla is thinking of a 3-digit number. * It is divisible by 18. * It is a palindrome (It reads the same left-to-right as it does right-to-left, like 252 and 848). * It is one less than a multiple of 5. What is Kayla’s number?
Answer:
414
Step-by-step explanation:
414 divided by 18 is 23
414 is a palindrome
414 is one less than 5

Simplify each expression by using the distributive property and combining like terms. 3 (2x - 4) - 4x
Given:
The expression is
[tex]3(2x-4)-4x[/tex]
To find:
The simplified form of the given expression by using the distributive property and combining like terms.
Solution:
We have,
[tex]3(2x-4)-4x[/tex]
Using the distributive property, we get
[tex]=3(2x)+3(-4)-4x[/tex]
[tex]=6x-12-4x[/tex]
On combining like terms, we get
[tex]=(6x-4x)-12[/tex]
[tex]=2x-12[/tex]
Therefore, the simplified form of the given expression is [tex]2x-12[/tex].
What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9
Hey there!
The answer to your question is [tex]4x^2+2x-2[/tex]
Given:
[tex]x^2-3x+7[/tex] [tex]and[/tex] [tex]3x^2 +5x-9[/tex]
First, we can start by adding like terms. The following are like terms:
[tex]x^2[/tex] [tex]and[/tex] [tex]3x^2[/tex]
[tex]-3x[/tex] [tex]and[/tex] [tex]5x[/tex]
[tex]7[/tex] [tex]and[/tex] [tex]-9[/tex]
Now, we can add these pairs together, giving us:
[tex]4x^2[/tex]
[tex]2x[/tex]
[tex]-2[/tex]
Now, add all this together, and we get our answer as:
[tex]4x^2 + 2x - 2[/tex]

Answer:
The measure of angle 6 is 72.
The measure of angle 7 is 108.
Step-by-step explanation:
Corresponding angles are equal. So angle 1, 3, 5 and 7 are all equal.
If you look at angle 1 and 2, they are adjacent angles, so together they add up to 180. So if you subtract 108 from 180 you get 72... and we already established that all corresponding angles are equal, so if angle 2 is 72 degrees, we can conclude that angle 6 is as well.

The sum of two numbers is 51, the difference is 17. Find the numbers.
Answer:
Sum: 34 + 17 = 51
Difference: 34 - 17 = 17
Step-by-step explanation:
math
Answer:
34, 17
Step-by-step explanation:
We can first get the two equations x + y = 51 and x - y = 17 by calling the first number x and the second one y. Next, we can add y on both sides in the second equation to get that 17 + y = x. Now, since we know that 17 + y is equal to x, we can substitute 17 + y in for x in the first equation. We get that 2y + 17 = 51, and if we subtract by 17 on both sides and get that 2y = 34. This means that y is equal to 17, meaning that x is 34.
