To convert a percent to a decimal, you move the the decimal left two places to convert the percent to a decimal. For example, if you were to convert 14% to a decimal, you move the decimal left two places so that 14% converted to a decimal would look something like this: 0.14
Answer:
Step-by-step explanation:
Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...
x + (x+40) = 1180
2x = 1140 . . . . subtract 40
x = 570 . . . . . .divide by 2
x+40 = 610 . . . . the speed of the faster plane
The two speeds are 570 mph and 610 mph.
Answer:
40 % of the snacks were carrot sticks.
Step-by-step explanation:
Total number of carrot sticks in lunch = 18
Total number of apple slices in lunch = 27
So, Total Snacks in the Lunch = Carrot Sticks + Apple Slices
= 18 + 27 = 45
Now, 
= 
⇒Percentage of Carrot Sticks = 40%
Hence, 40 % of the snacks were carrot sticks.
Answer: D) The balloon
Explanation:
Ignore the "above sea level" and "below sea level" portions. Focus purely on the numbers themselves. The largest value is the furthest away from sea level. The smallest value is closest to sea level.
Therefore, the balloon is furthest from sea level because 27 is the largest of the four values (5, 12, 18, 27).
Answer:
-1
Step-by-step explanation:
Simplify the following:
x - 2/2 - x
Hint: | Reduce (-2)/2 to lowest terms. Start by finding the GCD of -2 and 2.
The gcd of -2 and 2 is 2, so (-2)/2 = (2 (-1))/(2×1) = 2/2×-1 = -1:
x + -1 - x
Hint: | Group like terms in x - 1 - x.
Grouping like terms, x - 1 - x = (x - x) - 1:
(x - x) - 1
Hint: | Look for the difference of two identical terms.
x - x = 0:
Answer: -1
