Answer:
20 miles
Step-by-step explanation:
If Maria has been riding for 2 1/2 hours and Aiden only for 2. That means that the first 4 miles she rode alone was for 1/2 hour. So that is the rate.
1/2 hour for every 4 miles
Maria rode for 2 1/2 hours divided by 1/2 hours is 5. So 5 x 4mi = 20 miles
A Cause I just did that question
Answer:
Mass m = 20.04 grams
Correct question;
Sinker is a weight used by fishermen. A fisherman uses a sinker in the shape of a sphere with radius 0.75 cm. The sinker is made of lead, which has density 11.34g/cm^3. What is the mass of the sinker?
Step-by-step explanation:
Mass of an object can be defined as
Mass m = density p × Volume V
Given;
Density of the sinker = 11.34g/cm^3
Radius of the sinker = 0.75 cm
And we know that the volume of a sphere is given as;
V = 4/3 × πr^3
Substituting r, we have;
V = 4/3 × π × 0.75^3
V = 1.767 cm^3
Then we can calculate mass as;
m = pV
m = 11.34×1.767
m = 20.03778 g
m = 20.04 grams
This is not full question I think
