Let m be the density of iron
Let M be the density of copper
So, m = M = 101.5 grams
We know that the formula for mass is:
m = d x v
where:
m is mass
d is density
v is volume
the density of iron is calculated by d = m / v, we derived this formula from the mass formula.
So d = 6.8g/ 3.3cm^3 = 2.26 g/cm^3
It was said that the density of iron is more than the density of copper, so 6.8 should be greater than 2xd, it indicates that d is less than 3.4.
Therefore, the density of copper is more likely less than 3.4g/cm^3

Answer:
60 feets
Step-by-step explanation:
Given that :
Using Pythagoras rule :
Hypotenus = sqrt(Adjacent^2 + opposite^2)
From the attached picture :
x² = 87^2 - 63^2
x^2 = 7569 - 3969
X^2 = 3600
Take the square root of both sides :
X = sqrt(3600)
X = 60 feets
Hence, Katy and Tony are 60 feets apart
