Answer:
The constant of proportionality is 6
Step-by-step explanation:
Recall the equation for direct variation is [tex]y=kx[/tex] where [tex]y[/tex] varies directly with [tex]x[/tex] and [tex]k[/tex] is the constant of proportionality. If we take any listed coordinate point, we can determine the value of [tex]k[/tex]. I will use (20,120) as an example:
[tex]y=kx\\\\120=k(20)\\\\6=k[/tex]
Therefore, the constant of proportionality is 6

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.
Answers
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.

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.
Answers
Answer:
c

The variable y in the second equation has a coefficient of 2 so it will be easy to divide the entire equation by 2.

Answers
Answer:
100 and 101
Step-by-step explanation:
Hi there!
Let x be equal to the smaller number.
Let x + 1 be equal to the larger number, which is consecutive to the smaller number.
We are given that the sum of the two numbers is 201:
[tex]x+(x+1)=201\\x+x+1=201\\2x+1=201\\2x=200\\x=100[/tex]
Therefore, the smaller number is 100. Because the larger number is x + 1, it is 101.

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°.

A researcher has reported the standard deviation of a data set. What might be the reason they chose this measure of variability? a. When plotted, the data set had a normal distribution b. When plotted, the data set had one number that was more frequent than the others c. When plotted, the data set was skewed d. When plotted, the data had a large distribution
Answers
Standard deviations are used to measure the variability of the set
The reason they choose the standard deviation as the measure of variability is (a) when plotted, the data set had a normal distribution
How to determine the reason for the measure of variabilityWhen a data is distributed, the data can be measured using the median, the mean or the standard deviation.
If the data is a normal distribution, then the best measure of variability to use is the standard deviation
Hence, the true statement is (a) when plotted, the data set had a normal distribution

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.
Answers
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.
