in a packet of skittles there are 27% are red and 23% are green and the rest are blue what percentage are blue?
Firdavs [7]

Answer: 50% are blue.

Step-by-step explanation:

The total number of skittles  in the packet will be represented by 100%. If 27% are red and 23% are green then the combination of the red and green skittles subtracted from 100 will give the percentage of the blue skittles.

27% + 23% = 50%

100% - 50% = 50%  

This means half of the skittles in the packet are blue which is 50%.

What is the area of this triangle? (Image Attached)
Snezhnost [94]
\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}\\\\
-----------------------------\\\\
\textit{so, let's find the missing side}
\\\\\\
c=\sqrt{2.7^2+3.4^2-2(2.7)(3.4)cos(40^o)}
\\\\\\
c=\sqrt{4.78542402433556327368}\implies c\approx 2.187561204706182220

or we can round it, to say c = 2.19, so  hmm that's the missing side
now, we use Heron's Formula, which uses all 3 sides only

\bf \textit{Heron's Area Formula}\\\\
A=\sqrt{s(s-a)(s-b)(s-c)}\qquad 
\begin{cases}
a=2.7\\
b=3.4\\
c\approx 2.19\\\\
s=\cfrac{a+b+c}{2}
\end{cases}

and that'd be the area of it

494 divided by 14 is<br> remainde
True [87]

Answer:

494 divided by 14 = 35 with a remainder of 4.

Step-by-step explanation:

The remainder is the integer "left over" after dividing one integer by another to produce an integer quotient (integer division).

To calculate remainder, work the division in your calculator as normal. Once you have the answer in decimal form, subtract the whole number, then multiply the decimal value that's left by the divisor of your original problem. The result is your remainder.

I hope this was helpful to you! If it was, please consider rating, pressing thanks, and marking my answer as 'Brainliest.' It would help a lot. Have a wonderful day.

(1/3) × the cone's volume = The cylinder's volume.

Step-by-step explanation:

Step 1:

The volume of any cone is obtained by multiplying \frac{1}{3} with π, the square of the radius (r^{2}) and the height (h).

So the volume of the cone, V=\pi r^{2} \frac{h}{3}.

Step 2:  

The cylinder's volume is nearly the same as the cone but instead by multiplying \frac{1}{3} we multiply with 1.

So the cylinder's volume is determined by multiplying π with the square of the radius of the cylinder (r^{2}) and the height of the cylinder (h).

So the the cone's volume, V = \pi r^{2} h.

Step 3:

Now we equate both the volumes to each other.

The cone's volume : The cylinder's volume = \pi r^{2} \frac{h}{3}: \pi r^{2} h = \frac{1}{3} : 1.

So if we multiply the cone's volume with \frac{1}{3} we will get the cylinder's volume with the same dimensions.
