How would you choose to reduce the system shown to a 2 × 2? Explain why you would choose this approach. –3x y – 2z = 10 (1) 5x – 2y – 2z = 12 (2) x – y z = 23 (3)

Answers

Answer 1

Answer:

Eliminate y by adding equations (1) and (3) because the coefficients on y are opposites. Then eliminate y by multiplying equation (1) by 2 and adding it to equation (2). Eliminate z by subtracting equations (1) and (2) because the coefficients are the same. Then eliminate z by multiplying equation (3) by 2 and adding it to equation (1).

Explanation:

Wealthy merchants such as Cosimo de’ Medici ruled Italian churches to city states.

What is City states?

Ancient Greece had a polis, or city-state, form of government. Each city-state was set up with an urban core and the countryside surrounding it. In a polis, the city was enclosed by protective outside walls and included public areas with temples and governmental structures.

The summit of a hill, or acropolis, was frequently where the temples and political structures were erected. The well-known Parthenon in Athens is an iconic example of a monument that was the focal point of an ancient acropolis.

A temple dedicated to the goddess Athena was called the Parthenon. Since the city served as the epicenter of trade, commerce, culture, and political action, the bulk of people in a polis lived there.

adelaide sorted mineral samples into two groups: dull and shiny. which of the following properties did adelaide use to separate mineral samples into group?

Answers

Answer:

B. luster

Explanation:

This is about physical properties used in classification of minerals.

The four basic properties used to identify minerals from the ground are;

1) Luster; this is a property which shows how well the reflection occurs when a mineral is exposed to light.

2)color; different minerals have different colors and this is a good property to identify minerals.

3) diaphaneity; this is defined as the ability of a mineral to have light transmitted through it.

4) shape: this is also a good property to identify minerals.

There are other properties used to identify minerals like streak which is the colour of the powdered form of a mineral, hardness, fracture e.t.c.

Now,we want to classify the mineral samples as either dull or shiny. For a mineral to be dull, it means it will not be able to reflect light properly whereas if it is shiny, light will easily be reflected from it.

The only property of minerals in the options that corresponds with shiny or dull is the Luster property.

Thus, option B is correct.

The angle between the dock and the line connecting Michael and the ship is 48°, and the angle between the other dock and the line connecting Jacob and the ship is 37°. A triangle with points labeled Ship, Jacob, and Michael is shown. The length between Michael and Jacob is 20 miles. The angle between the ship, Michael, and Jacob is 48 degrees. The angle between the ship, Jacob, and Michael is 37 degrees. If the ship can travel to either dock, which dock would be closest? Explain your answer. Michael’s dock would be closer because the angle opposite is smaller. Jacob’s dock would be closer because the angle opposite is smaller. Michael’s dock would be closer because the docks are 20 miles apart. Jacob’s dock would be closer because the docks are 20 miles apart.

What are triangle inequalities?

The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for any triangle, the sum of the lengths of the first two sides is always greater than the length of the third side.

The vertices must be colinear, which means that the three sides form a line segment rather than a triangle if the length of one side equals the total of lengths of the other two sides. The triangle inequality is what we refer to here. Any triangle side must be shorter than the sum of the other two sides.

Therefore, the correct option is A.) Michael’s dock would be closed because the angle opposite is smaller.

How much interest will Michael earn on this CD in the first year, based on the nominal interest rate? $400 $600 $800 $1,000

Answers

Answer:$600

Explanation:

Interest will Michael earn on this CD in the first year, based on the nominal interest rate will be $ 600.

What is Interest rate?

An interest rate indicates how expensive borrowing is or how lucrative saving is.

Therefore, if you are a borrower, the interest rate is the sum you pay for borrowing money and is expressed as a percentage of the overall loan amount. For a loan of a certain size, the higher the percentage, the greater the amount you must repay.

If you save money, the savings rate will let you know how much, in terms of a percentage of your savings, will be deposited into your account. More money will be deposited into your account for a given deposit size the higher the savings rate.

Read the quote from President Wilson’s letter to the National Child Labor Committee. "As the labor situation created by the war develops I am more interested than ever, if that were possible, in throwing all the safeguards possible around the labor of women and children." The "labor situation" Wilson refers to most likely concerned him because: going to war meant US industry had to begin manufacturing military supplies. women and children had to do the jobs of male workers who became soldiers. no one was left to support families when men enlisted and went to war. women and children had to replace striking factory workers.

Answers

Answer:

B

Explanation:

Women demonstrated that they could perform “men's work” to a high standard during the Second World War. Thus, option C is correct.

What are the labor situation referred by Wilson?

Wilson backed and signed into law the Adamson Act, which secured an eight-hour workweek for railroad workers after American railroad unions threatened to strike in 1916. This act paved the way for shorter workdays for all industrial workers.

When males were recruited to military duty and the demand for war materials increased, women were granted access to manufacturing jobs.

For the soldiers, they made blankets, fixed shoes, laundered clothing, and sewed uniforms. Giving sick and injured soldiers medical attention during the conflict was arguably the most significant role played by women.

Therefore, women and children had to do the jobs of male workers who became soldiers.
