y = number of days
35.50 + 18.25 y = 163.25

18.25 y = 163.25 - 35.50

18.25y = 127.75

y = 127.75 / 18.25

y = 7

so Martin has hired the machine for 8 days

( first day paid 35.50), then 7 days for 18.25

A 4 foot tree was planted in 2012 outside a high school. The tree grew continuously by 22% each year from that point. Find out w

Brut [27]

Answer:

The height of the tree in 2020 was of 19.63 feet.

Step-by-step explanation:

Exponential equation for growth:

The exponential equation for the growth of an amount has the following format:

$H(t) = H(0)(1+r)^t$

In which H(t) is the amount after t years, H(0) is the initial amount and r is the growth rate, as a decimal.

A 4 foot tree was planted in 2012 outside a high school.

This means that $H(0) = 4$

The tree grew continuously by 22% each year from that point.

This means that $r = 0.22$

Find out what the height of the tree was in 2020.

2020 is 2020 - 2012 = 8 years after 2012, so this is H(8).

$H(t) = H(0)(1+r)^t$

$H(t) = 4(1+0.22)^t$

$H(4) = 4(1.22)^t$

$H(4) = 4(1.22)^8 = 19.63$

The height of the tree in 2020 was of 19.63 feet.

Lisa has a rectangular drawing that is 43.5 centimeters by 934 millimeters. How many centimeters of wood framing will she need?

KIM [24]

Lisa's drawing has the following dimensions:
Width=43.5 cm
Length=934 mm

but 1 cm =10 mm
thus
934mm when converted into cm we shall have:
length=93.4 cm

To get the total length of material required to frame the picture, we calculate the perimeter.
P=2(L+W)
P=2(93.4+43.5) cm
P=2(136.9)
P=273.8 cm

The total length of material required will be 273.8 cm
