Answer:
A. A + B (it'll be negative because they're both negative numbers and adding a negative is the same as subtracting a positive)
B. B - A ( It'll be positive because subtracting a negative is the same as adding a positive, and B is closer to 0 so it's a "bigger" number than A. so, adding A to B will make it positive)

Answer:
14400 blinks per day
Step-by-step explanation:
We need to convert minutes to days
60 minutes = 1 hour
24 hours = 1 day
The units will cancel leaving blinks per day.
150 blinks 60 minutes 24 hour 216000
---------------- * ---------------------- * ------------ = --------------- blinks/day
15 minutes 1 hour 1 day 15
14400 blinks per day
Answer:
1759.52cm^3
Step-by-step explanation:
Given data
Cylinder E
h = 30 cm and
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*30
V= 3.142*16*30
V=1508.16 cm^3
Cylinder F
h=5 cm
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*5
V= 3.142*16*5
V=251.36 cm^3
Hence the total volume is
=251.36+1508.16
= 1759.52cm^3
