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.)
All you have to do is times 15.5 with 9.48 and you get your answer witch is $146.94
It would be log3 14/log3 4
Hope this helps. (:
Answer:
<em>$2.29/gal</em>
Step-by-step explanation:
The unit price is in units of cost per volume, or dollars per gallon, so you divide the cost in dollars by the volume in gallons.
unit rate = ($18.32)/(8 gal) = $2.29/gal
Hey there! :)
Answer:
x = -24.
Step-by-step explanation:
Plug in the values to find the value of 'k':
-3 = k(6)
Divide both sides by 6 to solve for 'k':
-3/6 = k
k = -1/2
Plug this into the equation to solve for the value of x when y= 12:
12 = -1/2(x)
Divide both sides by -1/2:
-24 = x
x = -24.
