3.89 rounds to 3.9

This is because if you see the 8 and you have to round to nearest tenth you would see the hundredths place and see if it is greater than or less than 5. If it isles she than it would stay 3.8 but if it is greater than 5 it would be 3.9.

3.89 rounded to the nearest tenth is 3.9

You go to the tenths place which is 8, and then go to the number next to it. 9 is greater than 5, so you have to round up.

You regroup and get 3.9

3.9

Answer:

your question doesn't make sense if an electrician came to your house it would cost $40 then $55 dollars per hour but there is no way that you can solve that (40+(55•2)=150+55=205 which is already over $190 dollars

Arada [10]

Answer:

E, F, B, and C

Step-by-step explanation:

Im just learning about these kind of things and this is a challenging question not going to lie.

I chose B because expanding and building more factories is apart of economics. You need more land to expand your business, but this will also affect the economy.

C seems like a good answer also because writing about economic trends is an important thing in economics. This also helps others learn out the economy and what not to do and what to do to help make our environment a better place.

I chose E because starting a business is apart of economics. A lot of business are apart of economic systems and help money come into our economy.

F is a good answer for me because the U.S government has been apart of America's economic system for a long time just like they are involved with everything else. The government is a big help and a big part of our economy, especially for america.

Identify the two tables which represent quadratic relationships

madam [21]

Answer:

Option (4) and Option (5)

Step-by-step explanation:

By calculating the second difference, if the second difference in a table is equal, table will represent the quadratic relationship.

In the given option, we analyze that table given in Option (4) will represent the quadratic relationship.

x y Ist difference $(y_2-y_1)$ IInd difference

0 4 - -

1 -4 -4 - (4) = -8 -

2 -4 -4 - (-4) = 0 0 - (-8) = 8

3 4 4 - (-4) = 8 8 - 0 = 8

Second difference of the terms in y are the same as 8.

Therefore, table of Option (4) represents the quadratic relationship.

Similarly, in Option (5) we will calculate the second difference of y terms.

x y Ist difference IInd difference

0 -4 - -

1 -8 -8 - (-4) = -4 -

2 -10 -10 - (-8) = -2 -2 - (-4) = 2

3 -10 -10 - (-10) = 0 0 - (-2) = 2

Here the second difference is same as 2.

Therefore, table of Option (5) will represent the quadratic relationship.
