Answer:

We conclude that the value of k represented as a decimal rounded to the nearest tenth is: $k = 16.8$

Step-by-step explanation:

Given the expression

$\frac{5}{7}=\frac{12}{k}$

We need to determine the value of k, represented as a decimal rounded to the nearest tenth.

Let us solve the expression

$\frac{5}{7}=\frac{12}{k}$

Apply cross-function multiply: if $\frac{a}{b}=\frac{c}{d}$ then $a\cdot \:d=b\cdot \:c$

$5k=7\cdot \:12$

$5k=84$ ∵ 7 · 12= 84

Divide both sides by 5

$\frac{5k}{5}=\frac{84}{5}$

Simplify

$k=\frac{84}{5}$

$k = 16.8$ (Rounded to the nearest 0.1 or the Tenths Place)

Therefore, we conclude that the value of k represented as a decimal rounded to the nearest tenth is: $k = 16.8$

Answer: Choice A) An economic theory that is shared by the discipline of Psychology

Through the research I've found so far, the articles mention that economic choices have a psychological link. This is because economics is basically the study of human psychology (more or less) in terms of how to allocate resources and how best to use them. The law of diminishing marginal utility is basically the idea where the concept "more is always better" is simply not true. An example would be that you are at a restaurant and there's an endless buffet. The food isn't infinite and neither is the capacity of your stomach. After a certain point, you'll find that eating another burger isn't as satisfying as eating the first few burgers. You can think of it as a graph where the curve may start with a sharp increase, but eventually it levels off.

Side note: The term "affective habituation" may be used in psychology textbooks as something very similar to the law of diminishing marginal utility.

Find the value of x. Round your answer to the nearest tenth.

NikAS [45]

Answer:

In this question, we can use the Pythagorean theorem to solve for x.

11^2 + x^2 =24^2

x^2 = 24^2 -11^2

x is about 21.3

About 1.2 million people live in a region with a 6-mile radius what is the population destiny in people per square mile

Paladinen [302]

Answer:

10616 people per square mile

Step-by-step explanation:

No. of people living in the region = 1.2 million

Radius of the area = 6 mile

Since radius of region is given, area of can be calculated by using formula to get area of circle which is $\pi r^2$ where r is radius of circle.

the value of pie is 3.14 which will be used in the calculation

Area of region

$\pi r^2 \\=> 3.14 * 6^2\\=> 113.04$

population density of any place is calculated by dividing the total population of region with area of the region

mathematically it can be written as

population density of any place = the total population of region / area of the region

substituting the value of total population of region with 1.2 million and area of the region as calculated 113.04 square mile we have

population density of any place = 1.2 million/113.04 square mile

= 0.0106157113 million / square mile

Since one million is equal to 1,000,000

0.0106157113 million will be equal to 0.0106157113 * 1,000,000

= 10615.7113

rounding 10615.7113 nearest to unit value, it will be 10616.

Therefore, population density is 10616 people per square mile.
