Answer:

15 x 3^2

Step-by-step explanation:

The area of a square or rectangle is equal to the length x width.

If you want to scale the figure you multiply 3 to both the width and the length.

Because you are multiply 3 twice, you are essentially doing 3x3 = 9 or 3^2

15 ^ 3^2 is the answers.

You can also check on a calculator and it will also come as true

Find the height of the building below by using your knowledge of trigonometry.
Lilit [14]

Answer:

50\sqrt{3}

Step-by-step explanation:

The figure represents a 30-60-90 special triangle

in this special right triangle the measure of sides lengths is represented by

a, a\sqrt{3}, and 2a

The side length that sees angle measure 30 is represented by a and here we see a = 50m

The height of the building, which sees angle measure 60, is equal to

50\sqrt{3}

You have the formula. Put in the numbers and solve for r.

The interest earned in 4 years on 5000 is (6500 -5000) = 1500.
.. I = Prt
.. 1500 = 5000*r*4
.. 1500/20000 = r = .075 = 7.5% . . . . . . matches selection B

Use a stem-and-leaf plot to display the data, which represent the thickness (in centimeters) of ice measured at 20 different loc
navik [9.2K]

Answer/Step-by-step explanation:

To represent the data given on a stem and leaf plot, the whole number in a given value would be used as the stem, while the number after the decimal point is the leaf. (Key: 3|3 = 3.3).

For example, in the first stem in the first row, we have 4 as the stem. All values that starts with 4 point would be represented in this row. The digit after 4 point for each of the values would be written on the leaf column in the first row, from the least to the largest. For the first row we have: 4 | 3 9.

Same applies to the rest rows.

The stem plot would look like the one below:

Ice Thickness:

Stem | Leaf

4 | 3 9

5 | 1 8 8 8 9

6 | 5 8 9 9

7 | 0 2 2 2 2 5 9

8 | 0 7

The data of the stem-and-leaf plot shows a bell-shaped pattern with majority of the ice thickness for the 20 locations clustering around the center of the data distribution.

Kelly's team won 85% of the games they played in a season. The team lost 12 games. How many games did Kelly's team win in the se
mr_godi [17]

Answer:

68 games

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Games won = 85%

Game lost = 12

Here, 100% - 85% = 12

15% = 12

or 1% = 0.8

So, total games played (100%) = 80 games

Now, number of games won = Total games - Games lost

= 80 - 12

= 68 games

Hence, Kelly's team wins 68 games in the season.
