Answer:
1/2
Step-by-step explanation:
54,56,60,65,30,55,55,65,66 and 65
then place them in order from least to greatest
30,54,55,55,56,60,65,65,65 and 66
and to average they seem to grow equally over and under sixty inches.
1/2 or 50%
5 are lower than 60
and 5 are =/> 60
Answer: Choice B)
Work Shown:
Note: secant is positive in quadrant Q4, when theta is between 3pi/2 radians and 2pi radians (270 degrees and 360 degrees). So that's why we don't consider the minus form of the plus minus.
We have 60 gallons of 20% antifreeze.
How much 70% antifreeze do we add to get 60% antifreeze?
We'll make "x" the gallons of 70% we must add.
.20 * 60 + .70 x = .60 * (60 + x)
12 + .70x = 36 + .60x
.10x = 24
x = 240 gallons of 70% antifreeze.

you have to solve for X is somthnking
Answer: It's already in it's simplest form.
