By definition, the area of a rectangle is:
Where,
w: width of the rectangle
l: length of the rectangle
The total area is given by:
Where,
A1: rectangular wooden board 1
A2: rectangular wooden board 2
Substituting we have:
Rewriting we have:
Answer:
The width is given by:
Answer:
a. 277.3 m²
b. $307.86
Step-by-step explanation:
a. Area of the wall to be painted = area of rectangle - area of triangle
= L × W + ½×a×b×sin θ
L = 17 m
W = 14 m
a = 8.7 m
b = 9.5 m
θ = 72°
Plug in the values into the equation
Area of the wall = (17×14) + (½*8.7×9.5×sin 72)
Area of the wall = 238 + 39.3024105
Area of the wall to paint ≈ 277.3 m²
b. 20 liters of paint of 1 container cost $21.99
If 1 liter of paint covers 1m², therefore,
277.3 m² will need = 277.3 × 1 = 277.3 liters of paint.
20 liters = 1 container of paint
277.3 liters = 277.3/20 = 13.865 ≈ 14 containers
1 container = $21.99
14 containers = 21.99 × 14 = $307.86
Answer:
The expression gives the amount the plant earned per a man-hour of labor 3 years after it opened.
Step-by-step explanation:
Given:
Amount earned by Manufacturing Plant = $80/per man -hour labor
Percent increase in Amount earned by Manufacturing Plant each year = 6%
We need to find the expression gives the amount the plant earned per a man-hour of labor 3 years after it opened.
Solution:
Now we will use the expression;
Where;
⇒ Amount after t years
⇒ Initial amount
⇒ rate of change in amount
⇒ Amount of time
In The given data;
t =
So we can say that;
To find the amount the plant earned per a man-hour of labor 3 years after it opened we will substitute the value of t as 3.
Hence The expression gives the amount the plant earned per a man-hour of labor 3 years after it opened.
