Answer:

About 11.299 hours.

Step-by-step explanation:

To solve this problem, you can set up an equation to model the decay of the medicine. Let's call the time that medicine has been in the body x.

$(1-0.0595)^x=0.5$

$0.9405^x=0.5$

Taking the log x of both sides, you get

$x=\log_{0.9405} 0.5$

$x\approx 11.299$ hours. Hope this helps!

Associative Property of Addition

Let A, B and C be any three real numbers

A+(B+C) = (A+B) + C

Given data

(20.4 + 3.75) + 4.25 = 20.4 + (3.75 + 4.25)

= 20.4 + 8.0

The average distance from Venus to the Sun is 108,200,000 kilometers. Which of the following is the number expressed in scie

NISA [10]

Option C

ANSWER:

The scientific notation of 108200000 is $1.082 \times 10^{8}$ So the correct option is c.

SOLUTION:

Given,the average distance from Venus to the Sun is 108,200,000 kilometers.

We need to find the above given distance in the scientific notation.

Scientific notation is nothing but writing the large numbers as product of ten power something so that we can reduce space required to write that number.

Now, 108200000 can be written in scientific notation as:

= 10820000 x 10

$=1082000 \times 10^{2}$

$=108200 \times 10^{3}$

$=10820 \times 10^{4}$

$=1082 \times 10^{5}$

$=108.2 \times 10^{6}$

$=10.82 \times 10^{7}$

$=1.082 \times 10^{8}$

Hence the scientific notation of 108200000 is $1.082 \times 10^{8}$ So the correct option is c.
