The formula for a triangular pyramid is 1/3AH. A is the area of the base. H is the height of the pyramid. So to find the area of a right triangle, you would use the formula (a x b)/2. So (10 x18)/2 is 90 inches^2. Now you can fill in the first formula. 1/3(90 x 14), which equals 420 inches^3. I hope you find this helpful (if correct.)

Answer:
5:6
20:24
30:36
Step-by-step explanation:
In order to find an equivalent ratio, you have to multiply or divide your numerator and denominator by the same number.
For example:
10/12 x 3/3
30/36 = 30:36
10/12 is equivalent to 30:36

Answer: Choice (d)</h3>
Explanation:
To reflect over the y axis, we apply this rule
which says to flip the sign of the x term but keep the y coordinate the same.
So that means something like J(-2,5) becomes J ' (2, 5). The other points are handled in the same fashion and that leads us to choice (d). Points on the y axis will stay where they are.
I don't know if I understand the question but I think it is 15
