Taylor states that 2,800,000 in scientific notation is 2.8 x 10 -6 because the number has six places to the right of the 2. Is Taylor's reasoning correct?

Answers

Scientific Notation is the way of writing a number or expressing them in a shorter or more compact way.

No, Taylor's resoning is incorrect because  2,800,000 = [tex]2.8 * 10^{6}[/tex]

From the question, we are given:

2,800,000 .

2,800,000 in scientific notation is  [tex]2.8 * 10^{6}[/tex].  

The reason the power is not to the negative 6 is that we are moving from the right-hand side to the left-hand side 6 times.

Therefore, Taylor's reasoning is incorrect.

If you take out a loan for $561.60 over eight years at an interest rate of 9.3%, what is the total amount you will have to repay?

Answers

The simple interest of a given sum is directly proportional to the rate of interest. The total amount for repayment is $979.43.

What is Simple interest ?

The simple interest is a method of calculating the interest over a sum without considering the compounding.

The simple interest over a period of time varies as arithmetic progression.

Given that,

The amount of loan P = $561.60

Time for the interest T = 8 years.

Rate of interest R = 9.3%.

The total amount A can be given by summing the amount of loan to the interest over it as,

A = P + S.I

And the simple interest is given as,

S.I = (P × R × T) / 100

    = (561.60 × 9.3 × 8) / 100

    = 417.83.

The amount is given as,

A = 561.60 + 417.83

   = 979.43.

Hence, the total amount to be repaid is $979.43.

Answers

Answer:

pizza yum

Step-by-step explanation:

Answer:

$0.80 per square inch

Step-by-step explanation:

To find the cost per every square inch, divide the total cost of the pizza by the inches of the pizza. The pizza is 20 square inches and costs $15.99. The cost for every inch of pizza would be $0.7995, but you can just round that to $0.80 ($15.99/20 = $0.7995).

What is the slope of this line?

Answers

The slope of horizontal lines is zero because they are straight with no curve.

The slope is calculates using the rise over the run.

Rise= How many units we move up. Here we move 0 units.

Whatever the run is (NOT 0) if we divide 0 by the run, we will get 0.

Diagonal lines always have slope.

For thousands of years, ice cream has been a decadent dessert loved by most people around the world.There is some argument about who first invented ice cream. Some believe that ice cream was invented by the Chinese people anywhere from 2,000 to 6,000 years ago. They created a recipe of frozen milk and rice that was served as a dessert. Persia has also been credited with first serving frozen desserts. Over 2,000 years ago, the wealthy people of Persia enjoyed shaved ice from the mountains, covered with grape juice. They later learned to freeze rosewater and add different fruit toppings. These desserts were considered delicacies that only the richest families could experience. About 1,000 years after this, there is evidence that suggested Nero, the Roman Emperor, also enjoyed frozen treats and demanded that a constant supply of ice from the mountains be available to him. He liked to add honey to the top of his dessert.Ice cream as we know it can be traced back to the 9th century in Arab cities, such as Baghdad, Damascus, and Cairo. Near the end of the 13th century, Marco Polo returned to Italy after his travels through China with news of a frozen creamed dessert. In Europe, ice cream could only be found in Italy. Then, in 1533, Italian noblewoman Catherine de'Medici of Italy married Henry II of France. As Queen, Catherine introduced ice cream to France. Soon, the popularity of the dessert spread across all of Europe.Why is there an argument about who really invented ice cream?a: Ice cream wasn't created until the ice cream cone was invented. b: Many people around the world disagreed about which flavor of ice cream would be recognized as the first. c: Only wealthy people were given credit for inventing ice cream. d:There were many people from different places experimenting with frozen desserts around the same time.
