Answer:
(a) The total area of compound figure is
.
(b) The total perimeter of compound figure is 68.84 ft.
Step-by-step explanation:
Perimeter: The total distance covered by the figure.
Area: It is defined as the space occupied by the figure.
Given:
Length of rectangular figure = 19 ft
Breadth of rectangular figure = 12 ft
Radius of circle, r = 
Part (a):
Now calculating the total area of the compound figure.

Now putting all the given values in this formula, we get:

Part (b):
Now calculating the total perimeter of the compound figure.

Now putting all the given values in this formula, we get:

Answer:
2) 7x-6=2x+2
Step-by-step explanation:
It equals 8/9, and the equation, (5x + 2(x-3) = -2(x - 1)) equals 8/9 as well.
A 120 watt light-bulb is a 0.120 kilowatt light bulb.
In one hour, it uses 0.120 kilowatt-hour of energy.
If electrical energy costs $0.20 per kilowatt hour, then that light bulb costs
(0.120 kilowatt-hour / hour) x (0.20 dollar / kilowatt-hour) =
(0.120 x $0.20 / hour) =
$0.024 / hour = <span>2.4¢ per hour </span>
Answer:
for second question
first length is 9cm
Area=l*b
= 9cm *9cm
=81<em><u>cm</u></em>
then, For semicircle
radius is 9 cm
area= 1/2*9cm
now , area of two semi circle = 2*1/2*9
= 9 cm
now area of shaded = 81-9
=72
In the equation

divide both sides by
to get

Take the base-3/2 logarithm of both sides:

Alternatively, you can divide both sides by
:

Then take the base-2/3 logarith of both sides to get

(Both answers are equivalent)
