ANSWER
EXPLANATION
The volume of a pyramid is given by the formula,
The base of the pyramid is an equilateral triangle.
The base area is
The volume of the pyramid is now equal to:
12x¹y² / 3x²y²
= (12/3)x¹ ⁻ ² y² ⁻ ² By law of indices.
= (12/3)x⁻¹y⁰ y⁰ = 1<span>
</span>= 4x⁻¹
<span>
= 4 / x </span>
Answer:
402 mph
Step-by-step explanation:
Draw a right triangle with 400 and 40 as the two legs.
You know this is a right angle because 45 degrees NE is perpendicular to 45 degrees NW. (imagine a compass)
So, the two side lengths are 400 and 40
Using the Pythagorean theorem, (a^2 + b^2 = c^2) you can see that the answer is 401.995, or 402
