How do you calculate the mass of a solid copper cuboid with a density of 9.86 g/cm^3. The dimensions of the cuboid are 10 cm by 3 cm by 5 cm
step 1
Find the volume of the cuboid
step 2
Find the mass
we know that
To find out the mass multiply the density of the solid by its volume
so
Answer:
4y-x+6
Step-by-step explanation:
This means that...
the first worker does 1/8 of the job each hour.
the second worker does 1/4 of the job each hour.
the third worker does 1/4 of the job each hour.
So together they get 1/8+1/4+1/4 of the job done per hour.
Rate: 5/8 of the job per hour
Now if we know the rate, the job will be finished in...
1/(5/8) hours ----> 1.6 hours or 1 hour and 36 minutes
answer: 1.6 hours or 1 hour and 36 minutes

Answer:
-2
Step-by-step explanation:
The equation is -12/c=6
by solving for c you get,
-12/c=6
Then multiply both sides by the LCM c to get, -12=6c
Divide both sides by 6 to get,
-12/6=6c/6
-2=c
Verification:
-12/-2=6 since when a negative number divides a negative number the answer is a positive value
