Answer:
104.65 km/hour
Step-by-step explanation:
We need to convert miles to kilometers. The miles cancel so
65 miles 1.61 kilometers 104.65km
--------------- * ------------------- = -----------------
hour 1 mile hour
The speed limit is 104.65 km/hour
Answer:
Step-by-step explanation:
1) they have same slope of 2 and are, therefore parallel.
Segment FG is on the line 2 x - y= -3
y = 2x + 3
Slope = 2
segment EH is on the line 2x - y = 1
-y = -2x +1
y = 2x - 1
Slope = 2
The formula for the area of a rectangle is length times width, or A=l·w
The Area A=256
The width is w
The lenght is given as 6 feet less than 4 times its width, or in math language this is l=4w-6
Let's go back to the formula
A=l·w ⇒ 256=(4w-6)·w
simplify ⇒ 256=4w²-6w
put everything on the same side and set the equation equal to zero
⇒ 4w²-6w-256=0
Solve for w using quadratic formula
You are going to get two answers after using the quadratic formula: one positive and one negative. Just remember it doesn't make sense to get a negative answer if we are talking about width, so use the positive answer only
w≈8.7851 units
