At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. What percentage of the usual price is the savings? Explain or show your reasoning. Use whatever strategy you would like.

Answers

Answer: 15%

Step-by-step explanation:

The usual price is $80.

This week however, the set sold for $12 less than this usual price of $80.

Savings therefore are $12 because people save $12 by buying it at $12 off.

Percentage of usual price:

= Savings / Usual price * 100%

= 12 / 80 * 100%

= 0.15 * 100

= 15%

I believe the answer is D.

That’s because in radicals if there’s a square inside they square root that and put it on the outside. For example for √8, it would be 2√2, since the four can be square rooted, and there is still a 2 left inside the square root. For √48, there is a sixteen inside so you square root the 16 and get 4√3. Hope this helps

which graph models the solution of the Inequality -6 ≤ -3x

Answers

Answer- B

First make x the subject which would be -6/-3 ≤ x
Which is 2 ≤x and that is represented in B

We know that graph (B) models the solution of the given inequality -6 ≤ -3x.

What are graphs?Drawing the curve that represents a function on a coordinate plane is known as graphing a function. Every point on the curve will satisfy the function equation if the curve (or graph) represents the function.Line graphs, bar graphs, pie charts, scatter plots, and histograms are examples of common graph types. Graphs are a fantastic tool for displaying statistics and visualizing data. To depict numerical data that is unrelated to one another, a bar graph or chart may be utilized.

So, in the given inequality:

-6 ≤ -3x

We know that:

Make x subject: -6/-3 ≤ xWhich is 2 ≤ x, represented in a graph (B).

Therefore, we know that graph (B) models the solution of the given inequality -6 ≤ -3x.

The measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x . What is the value of x ?

Answers

By the interior angle theorem of triangles, the value of x is 5°.

What is a triangle?

A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.

We know the sum of the interior angles in a triangle is 180°.

Given, In a triangle DEF the measure of angle D is 50⁰, the measure of angle E is 80⁰, and the measure of angle F is 10x .

Therefore, m∠D + m∠E + m∠F = 180°.

50° + 80° + 10x = 180°.

10x = 180° - 130°.

10x = 50°.

x = 5°.

So, The value of x is 5°.

Identify and discuss 2 reasons why the safety of your workers in the workplace should be an important issue? PLZ HELP T^T TITLE:What Is Communism?What is communism? Communism was a plan designed to makeeveryone equal and to give power to the average working man. A Germaneconomist, Karl Marx, explained his idea of communism in his book "TheCommunist Manifesto," written in 1848. There is both an economic andpolitical aspect (side) to communism.In understanding the economic aspect, Marx declared that manyproblems in society are due to the unoqual distribution of wealth (manypoor and few rich). To bring about happiness and prosperity for all, the differences between the rich and poor must be eliminated and everyone should be equal(equality), which means you have to get rid of private ownership of property and business (privateenterprise). So, in Marx theory of communism, everyone owns everything, and the economy isowned and run by the govt. (socialism). And since the rich will never give up their goods or thepower they get from their wealth voluntarily, a rebellion of the poor -- the working class - isnecessary.Who will run the govemment, the political side of communism -- the people. But in practice,the govt is run by one or a few powerful leaders (dictators who represent the people andtherefore there is no need for other political parties. Therd Pay be elections, but only candidatesfrom the communist party can ran. Any other party would not represent the interests of all thepeople, i.e., ensure that all people benefit from the wealth of the country. The govt will takewhatever steps are necessary to ensure they maintain total control of the economic and political(govt) life of the country. In return, they will provide for the basic needs of all people (equality).The first country to be ruled by a communist government was Russia, (USSR). VladimirLenin, established rule by the Communist Party in Russia in the early 1900's through a revolutionthat overthrow the monarch. Russia had been ruled for centuries by a monarch, he was called the"czar." Most Russians labored on farms for little money, no education, and little hope ofimproving their lives or those of their children. Many people, while not believers in communism,wanted a government that would improve their difficult lives. The idea that communism wouldprovide that hope was popular among many.People in Russia were forced to do the work that the government dictated (said), and violenceagainst Russian citizens became common. Many poor citizens saw improvements in their livessuch as free education, basic health care, food and housing provided by the government. Othersexperienced the violence the government used against anyone they thought did not approve oragree with their role or the ideas of communism. Millions were sent to prison camps, executed,and others saw their businesses, homes, and farms taken by the government because undercommunism, the people, not, individuals own everything.
