Answer:
It took 12 hours to lose the water
Step-by-step explanation:
The total amount of water lost from Gerald’s bucket is inch
The amount of water he estimated to be lost in a single hour is inch
Dividing the total water lost by water lost per hour, we can get the the total number of hours it took to lose the water.
Therefore, it took 12 hours to lose the water.
Answer:
4+3n
Step-by-step explanation:
We get the formula 4+3n because the pattern is +3 each term starting with the first term as 7. Since the first term is 7, we get 4+3n.
This is a system of equations problem. Set up the 2 equations like so: If the angles are complementary then they add up to 90, therefore, a + b = 90. We also know that a is 16 more than b. The word "is" means equals and "more" is addition. Therefore, a is 16 more than b is "a = b + 16". Now sub in that value of a (b + 16) into the first equation and solve for b. Then back-substitute to solve for a. (b + 16) + b = 90 so 2b + 16 = 90 and 2b = 74. So b = 37. If b = 37, then a + 37 = 90 and a = 53. Check yourself to make sure that 37 + 53 add up to equal 90 (they do, just get used to checking yourself for accuracy).
To find the mean of something you are finding the average, so add all the times they were late to school. Then divide by the number of numbers you had to add. You will have your answer by doing that. What it means to interpret your answer is to explain it.
