Answer: Volume of vanilla ice cream in the cone= \dfrac{4\pi}{3}\ in^3

Step-by-step explanation:

Given : The diameter of cone = : d= 2 inches

Then radius of cone = Half of diameter = 1 inch

Height of cone = 6 inches.

Volume of cone = \dfrac{1}{3}\pi r^2 h , where r= radius , h= height of cone.

Then, Volume of cone = \dfrac{1}{3}\pi (1)^2 (6)=\dfrac{1}{3}\pi (6)= 2 \pi\ in^3

Since ice cream cone is filled with a vanilla and chocolate ice cream at a ratio of 2:

1.

Let x be the volume of chocolate ice cream , then the volume of vanilla ice-cream will be 2x.

Also,   Volume of cone=Volume of vanilla ice cream + Volume of chocolate ice cream

i.e. 2\pi = 2x+x\\\\ \Rightarrow\ 3x= 2\pi \\\\\Rightarrow\ x=\dfrac{2\pi}{3}\ in^3

Then , the volume of vanilla ice cream in the cone= 2x=\dfrac{4\pi}{3}\ in^3

\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\quad 
\begin{cases}
r=radius\\
h=height\\
----------\\
diameter=2\\
r=\frac{diameter}{2}\\
\quad = 1\\
h=6
\end{cases}\implies V=\cfrac{\pi\cdot  1^2\cdot 6}{3}
\\\\\\
V=2\pi \\\\
-------------------------------

\bf \cfrac{\stackrel{vanilla}{volume}}{\stackrel{chocolate}{volume}}\qquad 2:1\qquad \cfrac{2}{1}\implies \cfrac{2\cdot \frac{V}{2+1}}{1\cdot \frac{V}{2+1}}\implies \cfrac{2\cdot \frac{2\pi }{2+1}}{1\cdot \frac{2\pi }{2+1}}
\\\\\\
\cfrac{2\cdot \frac{2\pi }{3}}{1\cdot \frac{2\pi }{3}}\implies \cfrac{\quad \frac{4\pi }{3}\quad }{\frac{2\pi }{3}}

What is the equation parallel to 4y-3x=8
Andreyy89

Answer:

Whatever option has a slope of 3/4 and isn't y = 3/4x + 2

Step-by-step explanation:

This means that it has to have a slope of 3/4 (written as 3/4x + b). This is because parallel lines have the same slope; rearranging the first equation gets us y = 3/4x + 2. So, our slope for a parallel line has to be 3/4.

If a and b are odd integers, then a – b is an even integer.
Readme [11.4K]
So the answer choices are
1. a-b=even
2. a and b are not odd
3. a and b are odd
4. a-b=even
5. a-b=not even

even=not odd
not even=odd so choice 5 is really a-b=odd
basically choice 4 and 1 are the same so we cross one out
so
the problem said that a and b are odd so therefor choice2 is wrong and choice 3 is correct

then both are odd
odd-odd=even because
an even number is represented as 2n where n is an integer
an odd number can be represented as 2n+1 so assume you have 2 odd numbers 2 away from each other so odd and (odd+2)
odd+2-odd=2n+1+2-(2n+1)=2n+1+2-2n-1=2n-2n+1-1+2=2
you are left with odd
using integers
7 and 11
11-7=4
even

so odd-odd=even, it depends on weather you consider 0 odd or even


so the asnwers are:
a and b are odd
a-b is not an even integer
