The growth is decaying, the original value is 500 and the common multiplier is 5, 500 divided by 5 turns to 100. 100/5=20. 20/5=4. x/5 or 1/5 if it has to be in a fraction format
In order to list the measurements from smallest to largest, we convert all the measurement to a common unit. In this item, we convert the given to meters, m.
A. The conversion factor to be used here is 1 m = 100 cm
(7 cm)(1 m / 100 cm) = 0.07 m
B. Conversion factor: 1 m = 1000 mm
(18 mm) (1 m / 1000 mm) = 0.018 m
C. Let us list this as is, 1 m
D. The conversion factor here is 1 m = 10 dm
(3 dm)(1 m / 10 dm) = 0.3 m
By the converted values, we are then able to arrange the given measurements.Hence, the arrangement should be 18 mm, 7 cm, 3 dm, and 1 m.
Hold up. Hee haw. Whoa!
Your first instinct was to multiply it out and get rid of the parentheses.
That's often a good instinct, but this time, it made things harder for you.
This is a good example of a rule you should consider:
Before you do anything to anything, sit back, relax,
LOOK at the problem, THINK about it, and plan your
strategy. Decide what the solution might look like,
and what you're going to do to the given information
in order to move towards the solution.
You might look at this particular equation and ponder:
-- If I multiplied this thing out and got rid of the parentheses, it would
have x³ in it. So there are going to be 3 solutions.
-- If either factor is zero, then the equation is true.
-- One of the factors is 6x. Setting that to zero gives one solution: x=0.
-- The other two solutions come from setting (4x² - 4) = 0 .
-- That's the difference of 2 squares, so it's (2x + 2) (2x - 2) = 0
-- The other 2 solutions come from setting each of those factors to zero.
There you are. You got this far just by thinking, without even picking up
your pencil yet.
