Speed is the rate of distance over time.
<em>The speed of the boat is 13mph south-west</em>
Given
<em />
<em> --- west</em>
<em />
<em> -- south</em>
<em />
The speed is illustrated with the attached image
Because both speeds act at a diagonal, the speed (v) of the boat is calculated using Pythagoras theorem as follows:
Take square root
<em />
<em>Hence, the speed of the boat is 13mph south-west</em>

Answer:
see below
Step-by-step explanation:
Using the segment addition postulate
AB + BC = AC
x+2 + 7x-3 = AC
Combine like terms
8x -1 = AC
Using the segment addition postulate
PQ + QR = PR
8y+5 + QR = 13y+25
Subtract 8y from each side
5 + QR = 13y-8y+25
5 + QR = 5y+25
Subtract 5 from each side
QR = 5y+25-5
QR = 5y+20
Answer:
Step-by-step explanation:
At time zero the level was 7 gallons and at time 3 min, the level was 5 gallons.
<u>Take two points:</u>
<u>Find the rate of change:</u>
This is a 2 gallons per 3 minutes
<u>Tank holds 10 gallons, it was emptied by 3 gallons and it took:</u>
- 3 : (2/3) = 3* 3/2 = 4.5 minutes
Answer:
He will be 92 pounds by the time he is 1.
Step-by-step explanation:
If you add 9+3 thats 12. Then you keep adding nine until you did it 11 times. Then you will get his age.
