A plant is already 54 centimeters tall, and it will grow one centimeter every month. The plant's height, H (in centimeters), after M months is given by the following.
What is the plant's height after 13 months?
Answer:
67 cm
Step-by-step explanation:
We are given the initial height of the plant let's call it H.
H = 54 cm. This is the original height of the plant at M(months) = 0.
We are given that it grows at 1 cm/month. This is the rate of growth.
Rate = 1
Time (M) is given in Months.
So when M = 0, H = 54
Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.
When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.
H = 1M + 54.
Now we just plug in 13 for M, to get 13 months.
H = 13 + 54
H = 67 cm
So our plant would be 67 cm in height after 13 months.

Calculate the area of the parallelogram, giving your answer correct to 3 significant figures.
Answer:
114 units²
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, so
AB = CD , that is
13x - 7 = 5x + 9 ( subtract 5x from both sides )
8x - 7 = 9 ( add 7 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
Then
5x + 9 = 5(2) + 9 = 10 + 9 = 19
3x = 3(2) = 6
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height ), thus
A = 19 × 6 = 114 units²

A sports drink bottle contains 16.9 fluid Ounces. Andre drank 80% of the
bottle. How many fluid Ounces did Andre drink?
Answer:
13.52 fluid ounces should be the right answer! :)
Step-by-step explanation:
Andre drank from the bottle 13.52 fluid ounces if he drank 80% of bottle.
What is Percentage?Percentage is defined as the parts of a number in a whole of 100. This is denoted by the symbol '%'.
In other words, percentage can be defined as the ratio expressed as a fraction of 100.
Any number can be expressed as a percentage of another number by dividing the number with the whole of other number and then multiplying with 100.
Given that, fluid contained in a sports bottle = 16.9 fluid ounces.
Andre drank 80% of the fluid contained in the bottle.
80% of the bottle = 80% × 16.9
= (80 / 100) × 16.9
= 0.8 × 16.9
= 13.52
So this is the total fluid ounces Andre drink.
Hence Andre drank 13.52 fluid ounces from the bottle.
