Whats 2.3

Mathematics
1 answer:
vfiekz [6]3 years ago
5 0

Answer:

\frac{7}{3}

Step-by-step explanation:

We require 2 equations with the repeating decimal after the decimal points.

let x = 2.3333... → (1) ← multiply both sides by 10

10x = 23.333..... → (2)

Subtract (1) from (2), thus eliminating the repeating decimal

9x = 21 ( divide both sides by 9 )

x = \frac{21}{9} = \frac{7}{3}

Rate of Change- A scuba diver is 30 feet below the surface of the water 10 seconds after he entered the water and 100 feet below
nirvana33 [79]
We can create two points.

30 feet below the surface of the water 10 seconds after he entered the water
100 feet below the surface after 40 seconds

So we have (10, 30) and (40, 100)

Plug this values into the slope formula:

m = y2-y1/x2-x1

m = (100 - 30)/(40 - 10)

m = 70/30

m = 2 1/3
