When purchased, the height of a Japanese maple sapling is 14 inches. The tree is expected to grow 2.5 inches each month. Which f
victus00 [196]

Answer:

Step-by-step explanation:

The initial height of a Japanese maple sapling is 14 inches.

The tree is expected to grow 2.5 inches each month. This increase in height is linear, thus it is in arithmetic progression.

The expression for arithmetic progression is

Tn = a + (n-1)d

Where a = the first term of the series

d = common difference

Tn is the nth term of the series

n = the number of terms.

From the information given

a = 14 inches because it is the initial height of the tree

d = 2.5 because it is the difference in height between 2 consecutive months

n = m( number of months)

Tn = f(m)

function models the relationship between the height of the tree f(m) and the number of m months of growth will be

f(m) = 14 + 2.5(m-1)

Jaquez earns money by doing yard work. It takes her an average of 3 hours to pull weeds and an average of 2.5 hours to mow the l
vodomira [7]

Answer:

Step-by-step explanation:

Let x = number of hours to pull weed in a day

Let y = number of hours to now lawn in a day

It takes her an average of 3 hours to pull weeds and an average of 2.5 hours to mow the lawn. She can work no more than 8 hours a day.

This means

3x + 2.5y is lesser than/ equal to 8

She charges $50 to weed and $65 to mow the lawn.

This means she charges

50x +65y

She needs to cover her expenses of $120 to make a profit. This means she needs to earn an amount greater than or equal to $120

50x + 65y greater than or equal to 120

Angelo and Deborah are landscapers. Angelo charges a one time fee of $50 plus $15 per hour. Deborah charges a one time fee of $2
Tems11 [23]

Answer:

5 hours

Step-by-step explanation:

Step one:'

given data

Angelo charges a one time fee of $50 plus $15 per hour

let the total charge be y

and the number of hours be x

y= 50+15x----------------1

Deborah charges a one time fee of $25 plus $20 per hour

y= 25+20x----------------2

equate 1 and 2 to find x

50+15x=25+20x

collect like terms

50-25= 20x-15x

25= 5x

divide both sides by 5

x= 25/5

x= 5 hours
