Answer:
0.83 mi/min
Step-by-step explanation:
Start with 80 km/hr. Convert this to the units miles/hr:
(80 km/hr)(1 mile/1.6 km) = 50 miles/hr
Next, apply the equality 60 min / 1 hr = 1 to 50 miles/hr:
50 miles. 1 hr
------------- * ------------ = 5/6 mi/min, or 0.83 mi/min
hr 60 min

Answer:
x = 22.62° (nearest hundredth)
Step-by-step explanation:
As this is a right triangle, we can use the cosine trigonometric ratio to find x.
where:
- is the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
- A = 12
- H = 13
Substitute the given values into the formula and solve for x:
9514 1404 393
Answer:
B. neither perpendicular nor parallel
Step-by-step explanation:
If the lines were perpendicular, the coefficients would be swapped and one negated. (You would have 8x -y = c, or 9x +2y = c in the system.)
If the lines were parallel, the coefficients in the two equations would only differ by a common factor. (Both equations would reduce to 2x -9y = c, or x +8y = c.)
The lines are not the same line (coefficients are different).
So, the only reasonable description is ...
neither perpendicular nor parallel
F(c)= 2x+3 this should be the answer
