Answer:
16
Step-by-step explanation:
Given the equation, 
, let's solve for x as follows,
Subtract 200 from both sides
Subtract 15x from both sides
Divide both sides by -5
The height of the platform would be the last part of the equation
45 feet
Just find the volume of a triangular prism.
volume=1/2*length*width*height.
It looks like ∆ is defined as
<em>a</em> ∆ <em>b</em> = (<em>a</em> + <em>b</em>)² + 5
If that's the case, then
1 ∆ (-4) = (1 + (-4))² + 5 = (-3)² + 5 = 9 + 5 = 14
Answer: 3.44
Step-by-step explanation:
Step 1: Multiply the whole number by the denominator:
3 × 9 = 27
Step 2: Add the product you got in Step 1 to the numerator:
27 + 4 = 31
Step 3: Divide the sum from Step 2 by the denominator:
31 ÷ 9 = 3.444444
The answer to 3 4/9 in decimal form is displayed below:
3 4/9 ≈ 3.44
