Cosx = 0.5445
arccos(x) = 0.5445
x = 0.995
If you divide 5 (which is the amount of the numbers five and less on the dice) by the total amount of numbers, 12, then you come up with 0.4166666666666667, which rounded up would be 0.42.
Answer:
Step-by-step explanation:
In order to solve this exercise it is important to remember that a "Rate" is defined as a ratio that compares two different but related quantities.
Then, "Unit rate" tell us how many units of the first quantity corresponds to one unit of the second quantity. Therefore, the second quantity is equal to 1.
According to the information given in the exercise, you know that the number of hours of homework in 8 weeks is 240 hours.
Then, in order to determine the Unit rate (the number of hours per week), you need to divide 240 hours by 8 weeks.
Through the procedure explained above, you get the that the number of hours per week is the following:
(Notice that it is )
Answer:
0.25 miles
Step-by-step explanation:
The total distance off from her school is obtained by subtracting the distance traveled in a bus plus the distance walked from the total distance.
Given that she walks for half a mile and travels 2 miles in the bus:
Hence, the bus drop her 0.25 miles off from school.
The easiest way to do this is using and algebraic equation. First, 43% is equal to the decimal .43.
Multiplying the total number by the percentage gives you the answer, so
Let x = the number you're looking for.
X * .43 = 16
X = 16 / .43
X = 37.20930232558
Now, I'm assuming you're allowed to round so
37.2093
