a flat-bottom reflecting pool has length 30 yards, width 10 yards, and depth 0.3 yard. Find th e surface area of the pool and th
Zigmanuir [339]
The surface area of the object above can be calculated by summing up all the areas of the surfaces. Therefore, we will have 5 surfaces with rectangles as the shape. The volume would be the product of the length, width and the depth. We calculate as follows:

SA = 2(depth)(length) + 2(depth)(width) + (width)(length)
SA = 324 yd^2

VOlume = 30x10x.3
Volume = 90 yd^3

BEST ANSWER GETS BRAINLIEST
Alexandra [31]

Answer:

1. The speed of the truck, S = D/T.

2. The formula that connects D and T is: S = D/T.

3. The coefficient of variation, k, is the ratio of the standard deviation to the mean speed.

Step-by-step explanation:

a) The speed of a truck at a fixed speed is given as the distance covered by the truck divided by the time it takes the truck to cover the said distance.  This implies that speed is a function of distance and time.  However, this formula represents the mean speed.  There are variations in speed.

b) If the truck covers a distance of 60 kilometers, for example, under 3 hours, we can conclude that the speed is 20 kilometers per hour (60/3) or 20 km/hr.
