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:
Step-by-step explanation:
Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.
1.5=1 pound 7.5=5 pounds 10.5=7 pounds 16.5=11 pounds
Answer:
They are perpendicular lines
Step-by-step explanation:
If one line has slope -8 and the other one has slope 1/8, they must be perpendicular to each other because the condition for perpendicular lines is that the slope of one must be the "opposite of the reciprocal of the slope of the original line."
the opposite of -8 is 8 , and the reciprocal of this is 1/8
