Answer:
210 minutes
Step-by-step explanation:
First, we want to find out how many meters cubed of water there is, which is the volume.
The volume of this prism would be, the average of the two sides multiplied by 2 and 1.
1.5+0.6 = 2.1
2.1/2 = 1.05
1.05*2=2.1
2.1*1=2.1
2.1 meters is the volume but because it goes down by 30 cm, we have to convert 2.1 to cm.
2.1 * 100 = 210 cm.
Every 30 minutes, it goes down by 30 cm so:
210/30 = 7
210 minutes until it's empty
I know that 12-2 would be 10 in simplest form
Answer:
In component form, vector GH is <4, -5>.
Step-by-step explanation:
The head end of the vector (H, the one with the arrow) is 4 units to the right and 5 units below the tail (G).
The components are listed horizontal first, then vertical. The value of the component is the number of (unit) grid squares. Positive is up or to the right, as in the x-y coordinate plane. So, this vector is <4, -5>.
Answer:
2.4
Step-by-step explanation:
Find the mean.
4+8+10+6+2=30
30/5=6
Subtract.
6-4=2
8-6=2
10-6=4
6-6=0
6-2=4
Find the mean.
2+2+4+0+4=12
12/5=2.4
