Step-by-step explanation:
To find the rate, divide the number of heartbeats by the number of seconds.
You: 22 beats / 20 seconds = 1.1 beats per second.
Friend: 18 beats / 15 seconds = 1.2 beats per second.
The dimension of an object is a topological measure of the size of its covering properties. Roughly speaking, it is the number of coordinates needed to specify a point on the object. For example, a rectangle is two-dimensional, while a cube is three-dimensional. The dimension of an object is sometimes also called its "dimensionality."
the last digit is the ones place, if it is 5 or higher you would round up
under 5 you round down
so to the nearest 10 the number would be 67910
To do this, you make an equation; .18 = .75x
divide .75 on both sides, and x equals .24
Answer:
x = -50/7
