Pie equals 3.14 so if you turn that into a fraction you will get your answer
Answer:
B
Step-by-step explanation:
54/6=9 meaning each face has an area of 9.
Meaning each side has an area of 3.
That means the volume is 3*3*3=27
Answer:
She bought 22 pounds of blueberries.
Step-by-step explanation:
$86.90 divided by $3.95 = 22 pounds
When you have an expression to the power of (1/2) that means the same thing as having a square root.
Lets call a=x
To get rid of the square root we square both sides getting:
2x^2+5x+2= 3^2
Simplifying this we get: 2x^2+5x+2=9
We can subtract 9 from both sides getting: 2x^2+5x-7
Now when we solve for this we can use the quadratic formula:
(-b +/- sqrt(b^2-4ac)) / 2a
a=2 , b=5 , c=-7
Plugging in we end up with : (-5 +/- sqrt(81)) /4
This simplifies to : (-5 +/- 9) / 4 ..... (-5+ (-9))/4 OR (-5-(-9))/4
we have x= -14/4 , 1
to get the equation of any straight line, we simply need two points off of it, so hmm let's use the two points you see in the picture below from the provided table.
