Answer:

Sequence 1 is arithmetic, sequence 2 is geometric.

Step-by-step explanation:

Sequence 1 is being subtracted by 16 each time, so it is arithmetic.

Sequence 2 is being divided by 2 each time, so it is geometric.

Both, sequence 1 and 2, have terms 32 and 16.

stellarik [79]

<span>So the given numbers are:
=> One year, the price of wheat is 8.87 dollars
=> the next year, the price of wheat is 9.60 dollars.
We were asked to round each prices of bushels of wheat to its nearest tenths.
=> 8.87, where 8 before the decimal point is ones, 8 next to decimal point is tenths and 7 is the hundredths.
=>round off to the nearest tenths
=> 8.9
=> next is 9.60, where 9 is the ones value, 6 is the tenths value and 0 is the hundredths.
=> round off to nearest tenths
=> 9.6

timurjin [86]

Each angle on a triangle would add up to 180 degrees. Since a ladder goes straight up, that angle would be 90 degrees. If you add that with the 39 degree angle, you'd get 129. Subtract that from 180 and you have your answer.

Daniel is organizing his rock collection of 18 rocks into equal groups. How many possible ways can Daniel line up his rock colle

Colt1911 [192]

Answer:

The correct options are (2, 3 and 6).

Step-by-step explanation:

It is provided that Daniel has a rock collection of 18 rocks.

He wants to organize these 8 rocks into equal groups.

The factors of 18 are:

Factor (18): {1, 2, 3, 6, 9, 18}

A group is a selection of more than 1 items. So, there cannot be 18 groups.

And there cannot be 1 group, since then Daniel would not be organizing the rocks.

So, the possible ways Daniel line up his rock collection are {2, 3, 6 and 9}.

Thus, the correct options are (2, 3 and 6).
