Answer:

8.0 * 10^4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Explain how to determine if the two expressions are equivalent using x = 6 and x = 10. 8x 40 8(x 5)

Answers

The two expressions are equivalent, which gives the same values at x=6 and x=10 when put the values of x and compare them.

What is the equivalent expression?

Equivalent expressions are the expression whose result is equal to the original expression, but the way of representation is different.

The given expressions are,

[tex]8x +40[/tex]

[tex]8(x+ 5)[/tex]

It has to determine if the two expressions are equivalent using x = 6 and x = 10.

The value of the first equation at x=6 are,

[tex]8x +40=8(6)+40\\8x +40=48+40\\8x +40=88[/tex]

The value of the first equation at x=10 are,

[tex]8(10) +40=80+40\\8(10) +40=120[/tex]

Now, the value of the second equation at x=6 are,

[tex]8[(6)+5]=48+40\\8[(6)+5]=88[/tex]

Similarly, the value of the second equation at x=10 are,

[tex]8[(10)+5]=80+40\\8[(10)+5]=120[/tex]

The values of both equation are same at x=10 and x=6.

Hence, to determine, the two expressions are equivalent using x = 6 and x = 10, put the values of x and compare the values.

List the first five natural numbers.

Answers

[tex]1, 2, 3, 4, 5 [/tex]

Answer:

The first five natural numbers are 1, 2, 3, 4, and 5.

Step-by-step explanation:

Natural numbers, which include all positive integers from 1 to infinity, are a component of the number system. Natural numbers, which do not include zero or negative numbers, are also known as counting numbers. They are only positive integers, not zero, fractions, decimals, or negative numbers, and they are a component of real numbers. Numbers may be found everywhere around us, used for counting items, representing or transferring money, calculating temperature, telling time, and so on. "Natural numbers" refer to the numbers that are used to count items. When counting items, we may say 5 glasses, 6 books, 1 bottle, and so on. A collection of all whole integers except 0 is referred to as whole numbers. These figures play an important role in our daily actions and communication.  Natural numbers are those that can be counted and are a portion of real numbers. Only positive integers, such as 1, 2, 3, 4, 5, 6, etc., are included in the set of natural numbers. Non-negative integers are also known as natural numbers (all positive integers). 23, 56, 78, 999, 100202, and so forth are only a few instances. A collection of elements is referred to as a set (numbers in this context). In mathematics, the set of natural numbers is expressed as 1,2,3,... 1 is the lowest natural number. We know that the smallest element in N is 1 and that we can talk about the next element in terms of 1 and N for any element in N. (which is 1 more than that element). Two is one greater than one, three is one greater than two, and so on. The natural numbers from 1 to 100 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99 and 100.

Maybe mark brainiest

Dime = 10 cents

Nickel = 5 cents

Total value of coins = 3(10) + 4(5) = 30 + 20 = 50

To find the percent, first create a fraction. The fraction will be the amount of money that Benjamin has over the total (one dollar).

50 / 100 = 5 / 10 = 0.5

Suppose that spain has a workforce of 22.85 million people, and that the average salary for each person is €24,200 annually. spain has imports of €290.85 billion and exports of €200.13 billion. if the spanish government levies a 7% tariff on exports, an 18% tariff on imports, and a 21% income tax, how will the revenue gained from tariffs and the revenue gained from income tax compare? a. the government will earn €80.7214 billion more from tariffs than from income tax. b. the government will earn €29.5030 billion more from tariffs than from income tax. c. the government will earn €63.7707 billion more from income tax than from tariffs. d. the government will earn €49.7616 billion more from income tax than from tariffs.

Answers

The revenue that the Spain government gained from tariffs and the revenue gained from income tax compare as given by: Option d. the government will earn €49.7616 billion more from income tax than from tariffs.

How to find the percentage from the total value?

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we have these information:

Import amount = €290.85 billionTariff on import = 18% on import amountExport amount =  €200.13 billionTariff on export = 7% on export amountTotal people in Spain = 22.85 millionEach person's average salary = €24,200 annuallyTax on income = 21%

Calculating the earnings from tariffs and income tax:

Earning from imports = 18% of €290.85 billion = [tex]\dfrac{290.85 \times 10^9}{100} \times 18 = 52.353 \times 10^9[/tex] = €52.353 billionEarning from exports = 7% of €200.13 billion = [tex]\dfrac{200.13 \times 10^9}{100} \times 7 = 14.0091 \times 10^9[/tex] = €14.0091 billionTotal income earned by 22.85 million people = [tex]22.85 \times 10^6 \times 24200 = 552.97 \times 10^9 \ \: \rm (in \: euros)[/tex].

Tax generated from income = 21% of €552970 =

[tex]\dfrac{552.97 \times 10^9}{100}\times 21 = 116.1237 \: \rm billion \: euros[/tex]

Earning from tariffs = 52.353 billion + 14.0091 billion = 66.3621 billion

Difference in earning from income tax and tariffs is:

116.1237 billion - 66.3621 billion = 49.7616 billion euros.

Thus, the revenue that the Spain government gained from tariffs and the revenue gained from income tax compare as given by: Option d. the government will earn €49.7616 billion more from income tax than from tariffs.

Set up the problem as an equation where X is years: 14+X = (56+X)/2 Solve for X 14+X = 28 + 0.5*(X) subtract 14 from both sides: X = 14 + 0.5*(X) subtract 0.5*(X) from both sides: 0.5*(X) = 14 Solve for X by dividing both sides by 0.5: X = 28
