Population density is the number of people per unit of area. The population density of a certain region is 55 people per square kilometer. If the region covers 24 square​ kilometers, what is the population of the​ region?

If the equation is 0=0.64z-z+0.36z and the answer is true for all z what are 2 values to check the solution
Example of what I mean...

Answers

Answer:

You can choose trivial values such as [tex]z=0[/tex], but also something like [tex]z=69[/tex] if you feel more daring. Both equations will come out to yield [tex]0=0[/tex], which is obviously true.

Step-by-step explanation:

Because the answer is true for all [tex]z[/tex], any two values can be chosen. It is most often useful to choose easy values of [tex]z[/tex] for these kinds of situations, though.

69 is your answer have a great day

Taylor had $60 dollars to buy a new pair of sneakers. He saw a pair he really liked that originally cost $72 but were on sale for 15% off. Does Taylor have enough money to buy them on sale?

Answers

No! They do not have enough

Answer:

No.

Step-by-step explanation:

72 times 0.15=10.8

72-10.8=61.2

No. Taylor doesn't have enough.

You could also have done 72 times 0.85, and then you wouldn't have had to minus 10.8 and all those stuff.

Given a scale drawing of the square with a horizontal scale factor of 40% and a vertical scale factor of 240%, what are the dimensions, in units, of the scale drawing?

Your answer should fit the following format:

The length of the shorter side is _________ units, and the length of the longer side is _______ units.

Answers

Answer: The shorter side is 2 units, and the longer side is 12 units.

Step-by-step explanation: The original square is 5 units. multiply by decimal equivalents to find the new scaled units

40% of 5 is 2  That is: 0.4 × 5 = 2.0

240% of 5 is 12   That is 2.4 × 5 = 12.0

240

Last year Ron bought 40 pen sets and sold 25. This year he bought 75 pen sets and sold 60. The absolute error each year was the same. Are the percent errors also the same? Explain using the solutions.

Answers

Answer:200

Step-by-step explanation:

Answer:

No, different

Step-by-step explanation:

Last year

Bought 40 sets

Sold 25 sets

Error = 25 - 40 = -15Absolute error = | - 15| = 15Percent error =  15/40*100% = 37.5%This year

Bought 75 sets

Sold 60 sets

Error = 60 - 75 = -15Absolute error = |-15| = 15Percent error = 15/75*100% = 20%

We can see absolute errors are same but percent errors are different.

The reason is the referenced numbers are different.
