Answer:
its 72y
Step-by-step explanation:
12 *6=72
Add the y = 72y
Answer:
- boat: 15 mph
- current: 5 mph
Step-by-step explanation:
The relation between time, speed, and distance is ...
speed = distance/time
__
The speed downstream is ...
downstream speed = (100 mi)/(5 h) = 20 mi/h
The speed upstream is ...
upstream speed = (100 mi)/(10 h) = 10 mi/h
The boat's speed in still water is the average of these:
boat speed = ((downstream speed) + (upstream speed))/2 = (20 +10)/2 mi/h
boat speed = 15 mi/h
__
The speed of the current is the difference between the travel speed and the boat speed:
current speed = downstream speed - boat speed
= (20 mi/h) - (15 mi/h)
current speed = 5 mi/h
Answer:
the value of the z is -3.5
Step-by-step explanation:
According to the question, the following information is given
-2z - 7
Based on the above information
We assume that we have to determine the z value
so
-2z - 7 = 0
-2z = 7
z = 7 ÷ -2
= -3.5
Hence, the value of the z is -3.5
The same is to be considered and relevant too
Answer:
To know if Nicholas is correct
4(540π) inches³ ≥ 2304π inches³
Unfortunately, 2160π inches³ is less than 2304π inches³. This means Nicholas is absolutely wrong .4 times the volume of the cylindrical bucket is less than the volume of the spherical tank.
Step-by-step explanation:
The question wants you to look for the volume of the cylindrical bucket and the spherical bucket and know if 4 times the volume of the cylindrical bucket will fill the spherical tank.
volume of a cylinder = πr²h
where
r = 6 inches
h = 15 inches
volume of the cylinder bucket = πr²h
volume of the cylinder bucket= π × 6² × 15
volume of the cylinder bucket = π × 36 × 15
volume of the cylinder bucket = 540π inches³
volume of the spherical storage container
volume = 4/3πr³
r = 24/2 = 12 inches
volume = 4/3 × π × 12³
volume = 4/3 × π × 1728
volume = 6912π/3
volume = 2304π inches³
To know if Nicholas is correct 4(540π) inches³ ≥ 2304π inches³
Unfortunately, 2160π inches³ is less than 2304π inches³. This means Nicholas is absolutely wrong .4 times the volume of the cylindrical bucket is less than the volume of the spherical tank.
