Sylvester says that 0.000002015 written in scientific notation is 2.015 x 10 by the power of 6. Do you agree with him? Explain w

Marrrta [24]

Answer:

$0.000002015$ is not equal to $2.015x10^6$

Step-by-step explanation:

When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.

For example $50.000x10^3=50000$ and $45.00x10^{-3}=0.045$

$2.015x10^6=2,015,000$

wich is clearly not equal to 0.000002015

the correct scientific notation for 0.000002015 must be:

$2.015x10^{-6}$

With a negative in the power of 10, referring to a small quantity.

Lets x = Mary's age

Emily is there years older than twice her sister Mary's age = 2x + 3

Sum of both is less than 30:

x + 2x + 3 < 30

Solve for x

3x + 3 < 30

3x < 27

x < 9

Mary's age = 9

Inequality represents Mary's possible age:
