I think you should try this one yourself after I post my answer. Estimation is a very valuable tool -- the more you use it, the handier it gets.
Formulas
pi = 3
V = 4/3 * pi * r^3
Givens
r = 2
pi = 3
Solution
V = 4/3 * pi * r^3 Substitute values for symbols
V = 4/3 * 3 * 2^3 Cancel the 3s
V = 4 * 2^3 Expand the 2s
V = 4 * 2 * 2 * 2 Find V
V = 32
So we will be using 
form, in which m = slope and b = y-intercept. Since we know the slope (-8), all we need to do is solve for the y-intercept. We can do this by inserting (-2,2) into the equation and solve for b.
Firstly, do the multiplication: 
Next, subtract 16 on both sides, and your answer will be -14 = b
Using the previous info we have, our equation is y = -8x - 14
To convert into decimal, move the decimal to the left by 6 positions.
It will be 0.00000563
Answer is A.
Well let's see.
The equation has exactly one solution.
Hope this helps.
Answer:
At 11:50
Step-by-step explanation:
1. Subtract the hours and the minutes separately
12: 20
<u>- 0</u>: <u> 30</u>
12: -10
2. If the minutes are negative, subtract 1 from the hours and add 60 to the minutes.
12: -10
<u> - 1</u>: <u>+ 60
</u>
11: 50
You should remind PJ about her deliveries at 11:50.
