First you take the 20 hours it took for the 3 service calls... 20/3=6.67. Then you multiply 6.67X7.5=50.025 hours.
So we know that 2 workers can make 2 chairs in 2 days. Therefore if we use that same proportion, we will find that 8 workers can make 8 chairs in 2 days.
But the question is asking for 20 days, so we must multiply this by 10.
So, when we multiply 8 by 10, we find that in 20 days, 8 workers can make 80 chairs.
Answer:
<em>y = - 4x + 5 </em>
Step-by-step explanation:
y = mx + b
(0, b) y-intercept
m =
~~~~~~~~~~
( - 2, 13)
(0, <em>5</em>) <----- y-intercept
(3, - 7)
(4, - 11)
<em>m =</em>
= <em>- 4</em>
<em>y = - 4x + 5</em>
The area of △XYZ according to the figure is 363ft²
<h3>Area of triangles</h3>
The formula for calculating the area of a triangle is expressed as:
A = 0.5bh
- b is the base
- h is the height
<h3>Calculate area of each triangles</h3>
For the triangle △NMO
Area of △NMO = 0.5bh
147 = 0.5b(14/12)
147 = 7b/12
7b = 12 * 147
b = 252
b = 252ft
b = 3024in
Get the base of △XYZ
14/3024 = 22/XZ
XZ = 4,752in
Area of △XYZ = 0.5 (4,752)(22)
Area of △XYZ= 52,272in²
Area of △XYZ = 363ft²
Hence the area of △XYZ is 363ft²

Answer:

Step-by-step explanation:
As long as the two equations represent the same straight line on the coordinate plane (they overlap), there will be infinite many intersections and infinite number of solutions.
