This is the concept of density, volume and mass of different materials; To calculate for the volume of an aluminium material with density of 2.375 grams per cubic centimeter and a mass of 0.78 Kilogram we proceed as follows;
Density=mass/volumemaking volume the subject we get;volume=mass/densitythus;mass=0.78 kg= 780 gdensity=2.375 g/cm^3Hence,volume=780/2.375=328.421 cm^3
Answer:k equals 4.5
Step-by-step explanation: you multiply 1.5 times three
Answer:
Step-by-step explanation:
Given that you and a friend play a game where you each toss a balanced coin.
If the upper faces on the coins are both tails, you win $1;
if the faces are both heads, you win $2;
if the coins do not match (one shows a head, the other a tail), you lose $1 (win (−$1)).
Let Y be the amount won
Then Y can take values as 1,2 and -1

The above is the probability distribution for Y.
Area of pond:
A=
r=1,5m
A=3,142*1,5*1,5=7,0695
Area of pond with path
B=
r=50 cm+1,5m=0,5m+1,5m=2m
B=3,142*2*2=12,568
Area of path:
12,568-7,0695=5,4985=5,50
1,691,040,000
Hope this helps
