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.

which shape is not a trapezoid
Answers
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.

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?
Answers
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).

2) Christmas is on its way, so the price of a box of Thornton's chocolates has been increased
by 15%!! A box of Thornton's Continental now costs £17.25. How much did it cost
originally?
Answers
Our regular cost of chocolates is 1.0
New cost is 1.0 + 0.15 = 1.15
1.15 x 17.25 = 19.8375
In the states we round to the hundredth for cost, so it would be £19.84
Alternate method: calculate 0.15 of 17.25 and add that to 17.25
0.15 x 17.25 = 2.5875
17.25 + 2.5875 = 19.8375

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.

find the unit rate and show work
289 miles on 10 gallons
Answers
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

Answers
There are not equivalent to each other because the equation 2x+5=9 is equivalent to 2x=4
Answer: no.
Step-by-step explanation: 2x + 5 = 9 so subtract 5 from each side you get 2x = 4
X= 2
If we substitute that back in 2(2) + 5 = 9 so
If you do -2(2) = 4 it’s -4=4 and it’s not equivalent to each other
Because the statement is not correct.
