Answer:
Each tank holds 4.33 gallons of water.
Step-by-step explanation:
Gallons of water used to fill tanks = 13 gallons
Number of fish tanks filled = 3 fish tanks
To calculate the amount of water in one tank, we will divide gallons of water used to fill tanks by number of fish tanks filled.
Water in one tank =
Water in one tank = 4.33 gallons
Each tank holds 4.33 gallons of water.
Answer:
its 34z
Step-by-step explanation:
If you simplify the expression, it comes out to just 14.
Answer:
Option C
Step-by-step explanation:
See here the net seems like a equilateral triangle
- And another equilateral traingle is inscribed in it
- So 4 equilateral triangles
Hence option C

Answer: Choice B</h3><h3>
x = 9*sqrt(3) and y = 18</h3>
==============================================
Explanation:
The short leg is given to be 9 units long. This side is opposite the smallest angle. The rule is that smallest side is opposite the smallest angle. The hypotenuse is twice as long as the short leg in a 30-60-90 triangle, so 2*9 = 18 is the hypotenuse.
The long leg is equal to sqrt(3) times the short leg
long leg = (short leg)*sqrt(3)
long leg = 9*sqrt(3)
-------------
You can use the pythagorean theorem with a = 9 and c = 18 to solve for b
a^2 + b^2 = c^2
9^2 + b^2 = 18^2
81 + b^2 = 324
b^2 = 324 - 81
b^2 = 243
b = sqrt(243)
b = sqrt(81*3)
b = sqrt(81)*sqrt(3)
b = 9*sqrt(3)
It's a longer way to get the same answer as above for the length of the long leg.
