A scientist has a culture of bacteria. The initial culture starts with 500 bacteria, and the number grows by 20% per hour, h. Which equation can be used to find the number of hours it takes for the number of bacteria to reach 1,000?
O 1,000 - 500(0.20)
O 1,000 - 500(1.20)
O 1,000 - 500 +0.20h
1,000 - 500+ 1.20%

don't report but were is the digram

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.

40 i don’t know lololol

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
