Step-by-step explanation:
Given
Points (2,3) and (-3,8)
Required
Determine the gradient
Gradient (m) is calculated by dividing the change in y values by the change in x values.
i.e.
Where:
becomes
<em>Hence, the gradient is -1</em>
d ( f o c) / dt = 9
( solution is attached below)
Answer:
89 hours
Step-by-step explanation:
First solve all the deductions.
For each multiply the $10, which you are paid, and the percentage.
For FICA: $10 x 0.0765 = $0.77 per hr
For Fed tax: $10 x 0.12 = $1.2 per hr
For State tax: $10 x 0.08 = $0.8 per hr
Now subtract the remaining pay:
10 – 0.77 – 1.2 – 0.8 = $7.23
Time required = $640 / $7.23 per hr
Time required = 89 hrs
Final answer:
89 hours
The answer is 10 cm
Imagine cement cover as a rectangle which volume is 660,000,000 cm3. So this rectangle has width (w = 60m), length (l = 110m), and height (h = ?). The height of the rectangle is actually a thickness of the cement layer. So, we will use the formula for the volume (V) of the rectangle to calculate the thickness:
V = w · l · h
It is given:
V = 660,000,000 cm³
w = 60 m = 60 · 100 cm = 6,000 cm
l = 110 m = 110 · 100 cm = 11,000 cm
h = ?
Using the formula: V = w · l · h
660,000,000 = 6,000 · 11,000 · h
660,000,000 = 66,000,000 · h
⇒ h = 660,000,000 ÷ 66,000,000 = 10 cm
