The answer is D) The car travels 53 mph(Miles Per Hours).
212/4 = 53
318/6 = 53
424/8 = 53
530/10 = 53
Answer:
120*2.75*60/5280
= 3.75
Step-by-step explanation:
So James is walking at 120 steps a minute, there are 60 minutes in one hour, and 5,280 feet in a mile. So, to find how quickly James is walking, we multiply how many steps he is taking a minute by how much distance each step is (120 * 2.75) that gives us how much distance in one minute, so we then multiply by 60 because there are 60 minutes in one hour. Then divide the entire equation by how many feet are in one mile (5,280) giving us the answer 3.75 miles per hour. And the equation 120*2.75*60/5280
Both slopes have the same value which is 7.5.
To compute for the slope we will use this formula:
m = y^2 - y^1 over x^2 - x^1
For the first slope, the points are<span> (4, 30) and (12, 90). Substitute and simplify.
m = (90 - 30) over (12 - 4)
m = 7.5
For the second slope, the points are </span><span>(4, 30) and (10, 75). Same with the above computation.
m = (75 - 30) over (10 - 4)
m = 7.5
Since the relationship is linear, the slope does not change. </span>
Firstly, the negative sign indictaes that this is a decay. Secondly, it
is decaying by 31% (or 31 per 100) per annum, or 0.31, however, I dont
think any of these answers are right.
certainly C and D represent growth as they are 131% and 169% (1.31 and
1.69 respectively), B represents a decrease of 4% or 0.04, and A
represents a decrease of 87% or 0.87, which as you can see does not
correspond to to a decrease of -0.31or -31%, are you sure you have
supplied all the information in the question(such as a starting point).
If you have then I would refer to teacher/tutor for further examination.
