Sample question:

Aimee bought 2 CDs each costing $11.95 and 3 CDs each costing $6.48. She paid with a $50 note. How much change did she receive?

Answer:

2 × 11.95 = 23.9

A furniture store offers free setup and delivery services to all points within a 25-mile radius of its warehouse distribution center. If you live 20 miles east and 14 miles south of the warehouse, will you incur a delivery charge? JUSTIFY YOUR ANSWER!

Answers

Answer:

Step-by-step explanation:

make a good drawing and notice the right triangle with legs 20 mi and 14 mi

the distance from home to the warehouse is the hypotenuse c of the right triangle thus we will use the Pythagorean Theorem:

c^2 = 20^2 + 14^2

c^2 = 596

c = 24.41 mi approximately is the distance from home to a warehouse

since 24.41 < 25 you will incur a delivery charge.

Answer:

no, delivery charges will not be incurred

Austin correctly answered 92% of the questions on a geography quiz. Liz answered 47 of the 50 questions correctly. Which student got the most questions correctly.
(if you answer this may you please show your work)

Answers

Answer: Liz
To find the percent Liz got correct, you would do 47/50 to get 0.94. You would then move the decimal 2 places to get 94%.
94%>92%

Answer:liz scored better

Step-by-step explanation:

Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score

Here is a sequence of numbers:1361015What is the name given to these numbers? Four major candidates ran in the 1824 election, all under the "Democratic-Republican" name. One of the candidates, Andrew Jackson, was already famous. In the 1780s, he earned the right to practice law and served in various offices of the state government, including senator. He earned the nickname "Old Hickory" for his toughness as a general during the War of 1812 and First Seminole War. Jackson supported slavery and "Indian removal." This earned him support from voters in southern and frontier states. The other three candidates were John Quincy Adams of Massachusetts, Henry Clay of Kentucky, and William Crawford of Georgia.U.S. presidents are elected through the Electoral College. The Founding Fathers worried that Americans were too spread out to learn enough about the candidates. Under the Electoral College, Americans cast their ballot for the popular vote, which chooses the electors for each state. The number of electoral votes each state equals the number of representatives and senators combined. The candidates must win an absolute majority of electoral votes to win the election.In 1824, Andrew Jackson won the popular vote, but he did not win it in each state. Jackson and Adams both won many electoral votes. Jackson won the most with 99. However, a candidate needs an absolute majority of electoral votes to win. In 1824, Jackson needed 131 to win. When there is not majority winner, the election goes to the House of Representatives. This has only happened twice in U.S. history.Even though he won the popular vote and many electoral votes, Andrew Jackson lost the presidency in 1824. John Quincy Adams was the Secretary of State at this time. Henry Clay was the Speaker of the House of Representatives. Henry Clay, receiving the least, was left out. However, as a leader in the House of Representatives, he had influence over the other members. Clay openly hated Jackson and there were rumors that Clay made a deal with Adams in exchange for his support. The House election declared John Quincy Adams president. Soon, he chose Henry Clay to fill the seat he left vacant, Secretary of State. Jackson was shocked and enraged. Although there was no inquiry of possible wrongdoing, Jackson accused Adams and Clay of making a "corrupt bargain."John Quincy Adams was a disappointment as president. Many of his goals created divisions like federal funds for internal improvement. Some states thought that taking federal funds would force them to follow certain rules. They felt this reduced their rights as independent states. Jackson took advantage of issues like this one to gather more support. More Jackson supporters found their way to seats in Congress. He was as a man of the people and said Adams could never understand the common mans concerns.John Quincy Adams ran against Andrew Jackson in the 1828 election. Personal attacks grew even more vicious, but Andrew Jackson appealed to many. He believed government was for the common man. He believed in strict reading of the law and limited internal improvements. He also believed in states rights.Andrew Jackson easily won the 1828 election, winning both the popular vote and a majority of electoral votes. Historians note the sectional nature of the voting. Support for Jackson was concentrated in South while Adams support was mostly in the North. Jackson was so popular because he brought changes to the government. He also wanted to make sure the government was responsible for its actions. Jackson pushed settlement into the frontier. He supported the Indian Removal act. He also defended the spread of slavery. Though his support was heavier in the South, he was determined to keep a unified nation. The rise and presidency of Old Hickory is memorable to Americans today.Which best describes the purpose of the Electoral College in the United States?
