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.

To stock your school store, you buy a total of 25 sweatshirts and hats for $172.50. You pay $8.00 per sweatshirt and $2.50 per hat. How many of each item do you buy?
Answer:
the answer is 20 and 5
Step-by-step explanation:
Number of hats is 5 and the number of sweatshirts is 20
The total number of items bought is 25
The total amount is $172.50
Let a represent the number of sweatshirts
Number of hats is 25-a
Cost of sweatshirt= 8x
Cost of hat= 2.50×(25-x)
= 62.50-2.5x
8x + 62.50 - 2.5x-172.50
8x-2.5x+62.50-172.50
5.5x -110
5.5x= 110
x= 110/5.5
= 20
Number of hats= 25-20, = 5
Number of sweatshirts= 20

A number line can represent positions that are north and south of a truck stop on a highway. Decide whether you want positive positions to be north or south of the truck stop.
The truck stop
5 miles north of the truck stop
3.5 miles south of the truck stop
Answer:
The northern position would be positive while the southern position would be negative.
Step-by-step explanation:
Imagine 0 as the truck stop. North would be above the truck stop, while south would be below it.
On a number line, anything above 0 is a positive number. Anything below 0 is a negative number.
Therefore, the northern position would be positive while the southern position would be negative.

What is the Area and Perimeter for tbe rectangle?
length of rectangle = ( 4n-5 )
breadth of rectangle = ( 3n-2)
To find :-Area and perimeter of rectangle.
solution :-by the question ,
We know the area of rectangle = length × breadth
Area = (4n -5) (3n-2)
[tex] = {12n}^{2} - 8n - 15n + 10[/tex]
[tex] = {12n}^{2} - 23n + 10[/tex]
now ,
perimeter = 2 ( length + breadth (
= 2 ( 4n-5 + 3n-2)
= 2 ( 7n-7)
= 14n -14
