Answer:
Once you know the volume of the displaced water, you can immediately determine its weight by multiplying by the density of water at the relevant temperature. That's because the definition of density (d) is mass (m) divided by volume (v), so m = dv.
Step-by-step explanation:
<span>(x - h)² + (y - k)² = r²
is the equation of the circle with center (h, k) and radius r units.
Thus (x + 2)² + y² = 10 is the equation of a circle whose center is at the point (-2, 0) and having a radius of √10 units<u>

Answer:
The ride will take 2 h
Step-by-step explanation:
From the question,
Deon plans to ride a 20-mi bicycle trail, that is the total distance he plans to cover is 20-mi
Distance, d = 20 mi
Also, his average speed is 10 mi/h
rate of speed, r = 10 mi/h
To determine how many hours the ride will take,
From the formula,
d = rt
where
d is the distance covered
r is the average rate of speed
and t is the time.
We can solve for t, such
d = rt becomes
t = d/r
Now, from the question
d = 20 mi
r = 10 mi/h
∴ t = (20 mi) / (10 mi/h)
t = 2 h
Hence, the ride will take 2 h (hours)
the answer is the third one
