Answer:
9,000,000,000 gallons of water.
Step-by-step explanation:
We have been given that a website recommends that you should have 3 gallons of water for every inch of goldfish in your tank. We are asked to find the gallons of water needed for one billion goldfish that are each 3 inches.
First of all, we will find gallons of water needed for each fish.
Now, we will multiply number of gallons of water required for 1 fish by 1 billion to find required gallons of water.
Therefore, you need 9,000,000,000 gallons of water for 1 billion fish.
Answer:
grams of gold=8x10^12 g
Step-by-step explanation:
first we calculate the volume of the ocean this is achieved by multiplying the area by the depth
A=3.63x10^8 km^2=3.63x10^14 m^2
V=AxL
V=3.63x10^14 x 3800=1.3797x10^18m^3=1.3797x10^21L
then we multiply the volume in liters by the concentration of gold in the ocean per liter
grams of gold=1.3797x10^21 x 5.8x10^-9=8x10^12 g
Answer:
1/6
Step-by-step explanation:
She sold 12 cupcakes in total, 2 being coconut.
There would be a 2/12 chance that they would by a coconut cupcake. Simplifying it would be 1/6
We can use the pythagorean theorem to solve this
The pythagorean theorem = a^2 + b^2 = c^2, while
a = one leg
b = the second leg
c = the hypotenuse
In this problem,
a = 3
b = 15
c = ?
Let's plug our values into the pythagorean theorem
(3)^2 + (15)^2 = c^2
9 + 225 = c^2
Add together the left side
234 = c^2
Take the sqrt of both sides
sqrt(234) = c
The length of BC = sqrt(234)
