Answer:
density =8.87g/cm³
From chart the density shows that it is a Colsibro copper alloy, a precipitation hardening copper nickel silicon.
Step-by-step explanation:
This problem bothers on the density of substances
Given data
Mass m of substance = 239.6grams
length l=3cm
width b=3cm
height h=3cm
Volume of substance =l*b*h
=3*3*3=27cm³
We know that the density of the substance ρ=mass/volume
ρ= 239.6/27= 8.87g/cm³

Step-by-step explanation:
Answer:
18 hours
Step-by-step explanation:
First, he worked 3 hours babysitting, so he already made 8*3=24 dollars.
This means he must work 200-24=176 dollars lifeguarding.
Divide that by how much he makes per hour, and 176/15=11.7333 hours lifeguarding.
Round that up if he can't do a fraction of an hour to get 12 hours lifeguarding.
This is possible because the total hours worked is 12+3=15, which is less than 18.
