The rate of growth for a plant is 0.2 centimeters per 0.5 day. A student found the number of days for the plant to grow 3.6 centimeters to be 1.44 days. Which of the following explains the error and how to correct it? A)
The student found the unit rate of growth to be 0.1 centimeter per day. The unit rate is 0.5. So, the number of days for the plant to grow 3.6 centimeters is 1.8 days.

B)
The student graphed the relationship by graphing the point (0.2, 0.5). By continuing the line from the origin, the student should have found the point (3.6, 36). So, the correct number of days for the plant to grow 3.6 centimeters is 36 days.

C)
The student wrote the equation y = 3.6x to represent the relationship. The student should have used the equation y = 0.2x. The correct number of days for the plant to grow 3.6 centimeters is 7.2 days.

D)
The student created a ratio table and incorrectly placed 3.6 in the row with the number of days. The correct number of days for the plant to grow 3.6 centimeters is 9 days.

simple 80 pieces in 1 sercing so 80*47=3760+20=3780

here is me explaining it:

the pizza would be delivered around 5, give or take 15 minutes. this means it could be delivered anywhere from 4: 45 to 5: 15

let's say 5: 00 is equivalent to 0 on a number line and x represents time. 4: 45 would be equal to -15x because we are 15 minutes behind our starting point, 5: 00. 5: 15 would be equal to 15x because we are 15 minutes ahead of your starting point (which means you're late on the pizza delivery! )

absolute value is very confusing. the basic definition is how far you are from your starting point. if we deliver the pizza at 4: 45 (15 minutes before the starting point) we would be -15. this means we are 15 away from our starting point, 5: 00. that's the absolute value. |-15| (absolute value of negative fifteen) is equal to 15. if you did not understand this i suggest rereading this paragraph.

the normal way you would write this scenario would be 4.75 (4 and 3 quarters, or 4: 45. you can also write as a fraction.) is less than x and x is less than 5.25 (5 and 1 quarter or 5: 15). 4.75< x< 5.25 the reason why i am using numbers is because you cannot represent typical time as values on a graph, number line, or in an equation.

another way to write this scenario is with absolute value. we can write this as |x| being less than or equal to .25 (remember, this just means 15 minutes).           |x| ≤ .25.

sorry if the end was confusing. because we are talking about time this whole question is 10x harder. like i said earlier, you cannot represent time as, well, time, in a graph, equation, or number line. i set the values as follows: 1/4 or .25 for 15 minutes, and 1 for 1 hour. this is just a common way to set up graphs involving time.

|x| ≤ .25

i hope this ! : )
