Answer:
2n - 7
Step-by-step explanation:
To get the sum you would combine like terms.
So:
n + n= 2n
7 + -14 = 7 - 14 = -7
Put it together:
2n - 7

How do I calculate volume
Answer:
Volume = length x width x height.
You only need to know one side to figure out the volume of a cube.
The units of measure for volume are cubic units.
Volume is in three-dimensions.
You can multiply the sides in any order.
Which side you call length, width, or height doesn't matter.

Answer:
B. 5/3
Step-by-step explanation:
Take out the fourth root by doing 20/4 = 5. Then take out the third root by doing 5/3 so your answer is 5/3
Answer:
Answer = 5/3
Step-by-step explanation:
We simplify the squareroot to become ((x-5)^20)^1/12. Simplifying this further will get us (x-5)^5/3. We know that "b" is the exponent on (x-5), therefore the answer is 5/3.

A hard-boiled egg is removed from a pot of hot water and set on the table to cool. The rate of change of the egg’s temperature T with respect to time t is proportional to the difference between the egg’s temperature in degrees Fahrenheit ( °F) and the room temperature of 75°F. Which of the following is a differential equation that describes this relationship, where k is a constant?
Answer:
dT/dt = k(T-75)
Step-by-step explanation:
dT/dt = the rate of change of the egg's temperature T with respect to time t
k = constant
(T-75) = difference between the egg's temperature and the room temperature 75 degree
The relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).
From the Newton's law of cooling, the rate of cooling of any object depends on the temperature difference between the object and the surroundings. This is usually expressed in a differential equation.
In this particular instant, the differential equation that shows the relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).

find the unit rate and show work
289 miles on 10 gallons
Answer:
28.9 miles per gallon
Step-by-step explanation:
unit rate is usually something per something. Like miles per hour. In this case we have mile per gallon. MPG.
Unit rate is basically A number X per 1 of something.
so in this cares X per gallon.
we want 10 gallons to go to 1 gallon. So we divide by 10 to get to 1. But if we divide by 10 on one side, we have to do it to the other side. so 289/10=28.9
so our final answer is:
28.9 miles per gallon

Mrs. Liang, the librarian, wants to compare the numbers of patrons who prefer e-books to paperback books. She decides
to take a poll of every third adult with a child who arrives at the library for one of the four reading groups: toddlers,
preschoolers, primary grades, and upper elementary. Which statement is true about her method of data collection?
It is balanced because she is including parents with children of all ages so she will get a greater age range.
It is not balanced because it is less likely to include teens, young adults, and senior citizens in the patron population.
It is not balanced because she only surveyed the adults and not the young children.
It is balanced because she is polling four different reading groups, which include all types of people.
See
Answer: It's not balanced because it's less likely to include teens, young adults, and senior citizens in the patron population.
Step-by-step explanation: If wants to get a good sample for the whole "population," she should've taken broader samples of people of all ages.

which shape is not a trapezoid
Answer:
trapezium
If the shape you're looking at doesn't have at least one set of parallel sides, it's not a trapezoid; it's something called a trapezium instead. Similarly, if the shape has two sets of parallel sides, it's not a trapezoid. It's either a rectangle, a parallelogram shape or a rhombus.
