carlos had 24 class play tickets to sell. he sold 3/4 of the tickets. how many tickets did carlos sell
Answers
The answer is 18 but let me explain why that is. First of all let's assume (because it's true) that 3/4 is the same as saying 3/4 of one which is the same as saying 3/4 x 1 the answer then to that is 3/4 (go figure) so then using this logic we can say that 3/4 of 24 is the same as 3/4 x 24, which is an easy expression to evaluate if you have a calculator, but what if you don't, then what? Then you have to evaluate, 3/4 x 24 is the same as saying 3 x 24 = 72, then taking 72 and dividing by 4 which will give you 18, the answer. So I hope you can see the connection here, again if we have 3/4 of one we know that's the same as 3/4 x 1 which is equal to 1 x 3 = 3 then divided by 4 which is 3 divided by 4 which is the same as, you guessed, 3/4. Hope that helps, good luck with math in the future.

Answers
V = volume
R = radius
H = height
² = squared
radius = 10 cm
Height = 8 cm
V = π10²×8
V ≈ 3.14 * 100*8
V ≈ 2512
r = 10cm, h = 8 cm.
Volume = π*10²*8 = π*100*8 = 800π
Volume = 800π cm³ or ≈ 800*3.142 ≈ 2513.6
Volume ≈ 2513.6 cm³

Step-by-step explanation:
Lets label the consecutive odd numbers as 2n+1 and 2n+3 where n is an integer.
We need to prove that
((2n + 3)^2 - (2n + 1)^2 is a multiple of 8.
Using the difference of 2 squares on the left side:-
(2n + 3 + 2n + 1)(2n + 3 - (2n + 1)
= (4n + 4)(2)
= 8n + 8 which is a multiple of 8
Final answer:
The difference between squares of consecutive odd numbers can be expressed as 4n+4 which is a multiple of 8.
Explanation:
Let's take two consecutive odd numbers. We can express an odd number as 2n+1 where n is any integer. So, the consecutive odd number will be 2n+3 (adding 2 to the previous one).
Now, the squares of these consecutive numbers are (2n+1)² and (2n+3)² respectively.
The difference between these squares is (2n+3)² - (2n+1)². Applying the formula a² - b² = (a+b)(a-b), we get 4n+4 as the answer which is a multiple of 8 as 8 divides it without a remainder.
So the difference between the squares of consecutive odd numbers is a multiple of 8.

The x-intercept is -6
Step-by-step explanation:
In order to find the x-intercept, we put y = 0 and to find the y-intercept we put x = 0
In the given method, x is put equal to zero instead of y as x-intercept had to be found.
Given equation is:
Dividing both sides by -2
