$34 is a proper 20% tip on a $171.81 dinner. Move the decimal point twice to the left, then multiply that twice.
Answer:
30 and 20 respectively
Step-by-step explanation:
Let the number of sofas to be built be s and the number of recliners be r.
For the time part, we have the following equation:
8s + 6r = 340
For the money part:
180s + 105r = 6750
Now let’s solve these equations simultaneously.
Let’s change the form of the second equation:
180s + 17.5(6r) = 6750
From the first equation, 6r = 340 - 8s
Insert this into the third equation
180s + 17.5(340-8s) = 6750
180s + 5950 - 140s = 6750
40s = 6750 - 5950
40s = 800
s = 20
Substitute the value into the first equation
8(20) + 6r = 340
6r + 160 = 340
6r = 180
r = 30
The area of the region = area of the two rectangles = 64 units².
<h3>How to Find the Area of Rectangles?</h3>
A rectangle has a length and a width, and its area can be calculated using the formula below:
area of rectangle = (length)(width).
The region shown is composed of two rectangles. To find the area of the region, calculate the area of each of the rectangles in the image given.
Area of rectangle 1 = (length)(width)
Length = 12 units
Width = 4 units
Area of rectangle 1 = (12)(4)
Area of rectangle 1 = 48 units²
Area of rectangle 2 = (length)(width)
Length = 4 units
Width = 4 units
Area of rectangle 2 = (4)(4)
Area of rectangle 2 = 16 units²
The area of the region = area of the two rectangles = 48 + 16 = 64 units²
