Find the number of pieces that aren't red, by subtracting the red from the total:
11 - 5 = 6 are not red.
The probability is the number of none red, over the total number of pieces: 6/11
Answer: 56.25 of 70% and 93.75pints of 90%
Step-by-step explanation: First find the ratios. One juice is 70% and the other is 95%. Your goal is 85%. This is 15% from 70 and 10% from 95. This means you need (15)/(15+10) of 95, which is 3/5 of all the juice to be 95. This means you will need more of the 95% juice, which makes sense because 85 is closer to 95. So 3:5 and total 150=56.25 of 70% and 93.75pints of 90%
Final answer: 5
Step by step process:
You can make the equation a little simpler by putting in the 3 for x
btw I show exponents with this ^
(3)^2/3 + 2
3^2=3*3=9
Now you have 9/3 + 2 and you keep simplifying
9/3=3
3+2=5
Final answer: 5

Answer:
6
Step-by-step explanation:
You can memorize these for the smaller shapes
for equilateral polygons:
triangle: 60
square: 90
pentagon: 108
hexagon: 120
Otherwise, I believe the formula is the total degrees in a polygon (s-2)*180 where s is the number of sides.
So the measure of each angle on average would be (s-2)*180/s.
There (s-2)*180/s = 120
180(s-2) = 120s
180s-360 = 120s
60s = 360
s = 6
