An average person's heart beats about 103,680 times a day. write and solve an equation to find about how many times the average person's heart beats in one minute.I really need help on this math
Answers
24 hours in 1 day 60 minutes in one hour
60x24=1,440 minutes in a day
103,680/1,440 = 72 beats per minute
60x24=1,440
103,680/1,440=72 beats per minute
an average human heart beats 72 to 80 beats per minute

A baseball diamond has an area of 3600 feet to the second power. what is the distance between each base? .
Answers
The base ball diamond has the dimensions of a square. See the diagram in the attachment.
Therefore the area is given by the formula
We were given the area to be 3600 feet squared. We just have to substitute this value into the formula to obtain;
Taking the positive square root of both sides gives;
Thus implies that;
We can also rewrite this as;
The distance between each base is how far one side is from the other. This is equal to the perpendicular distance between them and this is the same as the length of the sides.
A diamond is the same thing as a square. So the side lengths are all the same. Multiplied length by width you get area. So square the area (3600) and you get 60 feet side length. The bases are 60 feet away from each other.
