Answer:
C
Step-by-step explanation:
If the cost is represented by n, why would you subtract the cost of the notebook by 0.78 while multiping it witht the cost?
1 x 72<span>, </span>2 x 36<span>, </span>3 x 24,4 x 18<span>, </span>6 x 12<span>, or </span><span>8 x 9</span>
62%
of 25
'of' means multiplication.
Convert 62% to a decimal, divide it by 100(since percentages are parts of 100):
62/100 = 0.62
Multiply:
A. T= d/r
A good way to remember this is by making a pyramid with 3 parts and putting distance at the top and rate and time in the other two parts. This way you can visibly see the equation and use it if you need to find one for rate.
B. It's reasonable to write distance as a positive number because distance is always positive. You are not able to have a negative distance. Imagine someone standing on a side walk. Even if they are not moving, their distance is 0 which is positive. If they move backwards or forwards, their distance is still positive because it is more than that 0 and they are gaining something.
C. Just plug in the numbers into the formula.
T= d/r
T= 32.12 m /<span>8.8 m/min
T= 3.65 min
