According to the rate of change, it is found that the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.
What is the average rate of change?
The average rate of change of a function is given by the change in the output divided by the change in the input.
In this problem, it is stated that at the top of the mountain, the average rate of change is of -2.5 ºC per hour, and at the bottom of the mountain the rate is the same, hence the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.

A person bought some Australian dollar of NRs 1,50,000 according to the exchange rate. Australian dollar 1 = NRs 77.02. After five days, in compare to Australian dollar the Nepali currency is devaluated by 5%. What is the profit or loss of that person when he exchanged the dollors he had into Nepali rupees again in that day? Find it.
Answer:
5.26% profit (NRs 7,894.24)
Step-by-step explanation:
The exchange of 1,50,000 NRs to A$ will give ...
A$ 1/(NRs 77.02) = x /1,50,000
x = A$ 1,50,000/77.02 = A$ 1947.54 . . . . . (rounded down)
If the Nepali rupees are devalued by 5%, then what did buy A$ 1 will now buy only A$ 0.95. Then the exchange back to NRs will give ...
(NRs 77.02)/(A$ 0.95) = x/(A$ 1947.54)
x = NRs (1947.54)(77.02/0.95) = NRs 1,57,894.24
The effective profit is the difference from the amount initially exchanged, NRs 7,894.24, or ...
(1,57,984.24/1,50,000 -1) × 100% ≈ 5.26%
__
Additional comment
Except for the loss in the exchange due to rounding down, the profit would be 1/0.95 -1 = 5.2632%. Instead, it is 5.2628%. This is why investors move their money to investments that retain their value when the local currency is losing its value.
After all, tryouts are completed, the school will be hosting a party for all the new athletes. At the party, hot dogs and hamburgers will be provided to all athletes and their guests, if they choose to bring a guest. The ratio of hot dogs purchased to a number of guests is 1:0.8. Determine how many hot dogs you would need if 150 people attend the party.
Explanation:
h = number of hot dogs
The ratio of people to hot dogs is 1:0.8
If 150 people show up to the party, then
(number of people)/(number of hot dogs) = 1/0.8
150/h = 1/0.8
150*0.8 = h*1 ... cross multiply
120 = h
h = 120
You'll need 120 hot dogs.

The laptop screen turns off when the angle between the keyboard and the screen is less than 20°. How many more degrees can the laptop screen close before the screen turns off?
The laptop screen can close ?° more before the screen turns off
Answer:
40⁰
Step-by-step explanation:
z+40+z-20=180
2z+20=180
2z=160
z=80
z-20=80-20=60
the laptop screen of in 60-20=40⁰
The laptop screen turns off at 40°.
What is a linear pair?Two neighboring angles that add up to 180 degrees are referred to as a linear pair, as are two angles that, when added together, create a line or a straight angle.
Given, the angles (z + 40)° and (z - 20)°.
The angles (z + 40)° and (z - 20)° form a linear pair, and the sum of the linear pair is 180°, therefore,
(z + 40)° + (z - 20)° = 180°
2z + 20 = 180
2z = 160
z = 80
The value of (z- 20)° is:
(z- 20)°
= (80-20)°
= 60°
The laptop screen turns off at
60° - 20°
= 40 °
Hence, the laptop screen turns off at 40°.

Jerry solved the system of equations.
x minus 3 y = 1 7 x + 2 y = 7.
As the first step, he decided to solve for y in the second equation because it had the smallest number as a coefficient. Max told him that there was a more efficient way. What reason can Max give for his statement?
The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.
The variable x in the second equation has a coefficient of 7 so it will be easy to divide 7 by 7.
The variable y in the second equation has a coefficient of 2 so it will be easy to divide the entire equation by 2.
The variable x in the second equation has the largest coefficient. When dividing by 7, the solution will be a smaller number.
Answer:
c
Step-by-step explanation:
The variable y in the second equation has a coefficient of 2 so it will be easy to divide the entire equation by 2.

2x = 2 x 25?
50 + ? = 150
50 + 100 = 150
x = 50?
2x + 50 = 150
2 x 50 + 50 = 150
100 + 50 = 150
The answer is x = 50.The measure of x is 50.
What are Vertical Angles?Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines. Because they are opposite each other, they are also known as vertically opposite angles.
Using Vertical Angle property as
(50+ 2x) = 150
So, subtract 50 from side we get
50 + 2x - 50= 150 - 50
2x = 100
Now, divide both side by 2 we get
2x/2 = 100 / 2
x = 50

Fiona’s mom bought 36 apples for Fiona and her 9 friends to eat. They each ate the same number of apples. Each of them only ate whole apples. How many apples were left over from the 36 her mom bought?
Answer:
6 Apples
Step-by-step explanation:
Fiona and her nine friends would make ten friends in total
They each ate whole apples and the same amount
So, 36÷10 would equal 3 apples eaten each with a remainder of 6 making 6 apples leftover
