Answer:
I(7) = 22.96 W/m²
Step-by-step explanation:
Let intensity of light, be I(d) where d is distance. There must be a proportionality factor K such as
I(d) = K /d²
Now for d = 5 m I(d) = K* 1/d²
then 45 * 25 = K
K = 1125
To find the intensity when the distance from the light bulb is 7 m away
I(7) = K / 49
I(7) = 1125/49 W/m²
I(7) = 22.96 W/m²
The answer is <span>C. 9/25.
There are in total 25 marbles:
6 green + 9 red + 7 white + 3 black = 25 marbles.
There are 9 red marbles of the total 25 marbles. You can draw 9 red Thus, the probability of drawing a red marble out of the bag is 9 out of 25, which is 9/25.</span>
Answer:
2.5%
Step-by-step explanation:
After 10.4 ounces, the number of adults goes down drastically. The rest of the options are 47.5%, 95% and 97.5%, which are not the answers. Hence, the answer is 2.5%.
Answer:
77% and as a fraction it would be 77/100
Step-by-step explanation:
0.77 is a decimal that is in the hundredths place so you already know that it'll be 77% right away then for the fraction you would just put it over 100 but since 77 is an uneven number you cannot simplify it otherwise you would.
