Answer:

Rounding decimals is very similar to rounding other numbers. If the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change.

Step-by-step explanation:

Example: rounding 0.813 to the nearest tenth would give 0.8

Example: rounding 0.572 to the nearest tenth would give 0.6

If the number is higher then 5 you will round up if it is lower it will stay the same

Hope this helps

In 1980, the average cost of a pack of cigarettes was $0.88. In 2000, the average cost was $5.31 per pack.

yan [13]

Answer:

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average rate of change is slope.

Step-by-step explanation:

The average rate of change of the cost of a pack ( $r$ ), in monetary units per year, is equal to the change in the average cost of a pack ( $\Delta c$ ), in monetary units, divided by the change in time ( $\Delta t$ ), in years. Then, the average rate of change is:

$r = \frac{\$\,5.31-\$\,0.88}{2000-1980}$

$r = \$\,0.22\,\frac{1}{yr}$

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average rate of change is slope.

Vertex A in quadrilateral ABCD lies at (-3, 2). If you rotate ABCD 180° clockwise about the origin, what will be the coordinates

Leni [432]

Answer:

A. (3, -2)

Step-by-step explanation:

A 180° rotation about the origin places an object in the quadrant diagonal to the one it started in. Moving the object two 90° turns, will place it in a coordinate that will make the values of 'x' and 'y' opposite to the initial value. In this case, vertex A has an initial point of (-3, 2), so after a 180° rotation, it would be (3, -2).
