Steps to solve this-- Find the percent of increase from 380 to 440. Round to the nearest tenth of a percent if necessary. 13.6%
OLga [1]
If 380 would be 100%

Then use rule of 3

380 ______ 100%

440 ______ y

380y = 440×100%

380y = 440 × 1

Dividing both the sides by 380

y = 440/380

y = 1,158

Let's multiplity "y" by 100

y = 115,8%

As we did have 100% initially

Then the increase will be

The increase = 115,8% -100%

= 15,8%

This would your answer

A base of ten raised to a negative exponent corresponds to a number that is-
Masteriza [31]

Answer:

A base of ten raised to a negative exponent corresponds to a number that is between 0 and 1.

Step-by-step explanation:

A base of ten raised to a negative exponent, say - 1 will correspond to the number, 10^{- 1} = \frac{1}{10^{1}} = \frac{1}{10}.

Again, a base of ten raised to a negative exponent, say - 2 will correspond to the number, 10^{- 2} = \frac{1}{10^{2}} = \frac{1}{100}.

{Since we know the property of exponents as x^{- a} = \frac{1}{x^{a}}}

Therefore, all those numbers are between 0 and 1.

Hence, a base of ten raised to a negative exponent corresponds to a number that is between 0 and 1. (Answer)
