1/4 of 96 were sold... replace "of" with ×

1/4 × 96 = 96/4 = 24

So the first month 24 houses were sold so that leaves...

96 - 24 = 72 houses.

1/3 of 72 were sold the next month

1/3 × 72 = 72/3 = 24

24 houses were sold the second month so there are...

72 - 24 = 48 houses left

Find the geometric mean between 12 and 20 find the answer in radical form
shusha [124]

Answer:

4√15

Step-by-step explanation:

The geometric mean of x and y is √(xy).

So here we have:

√(12*20)

= √240

= √(16*15)

= √16√15

= 4√15.

The amount of paint that David needs to cover a cube is directly proportional to the surface area. If David can completely cover
Inessa05 [86]

Answer:

The cube must be 21.125 feet long.

Step-by-step explanation:

David can completely cover a cube of side length equal to 2 feet, using 16 quarts of paint.

With this we make a conversion factor:

\frac{2}{16} feet/quarts = 0.125 feet/quarts

This means that with each quart of paint you can paint a 0.125-foot long cube

We need to know how big is the length of a cube that can be covered with 169 quarts of paint

Then we use the conversion factor found earlier

\169quarts * \frac{2pies}{16quarts} = 21.125 feet.

The cube must be 21.125 feet long.

PROBLEMS TO SOLVE
marta [7]

A graph for the data (time and distance) shown in the given table is plotted in the image attached below.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

<h3>What is a linear function?</h3>

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

This ultimately implies that, the data of a linear graph are directly proportional and as such as the value on the x-axis increases or decreases, the values on the y-axis also increases or decreases.

In this exercise, you're required to plot a graph for the data (time and distance) that are recorded for an object that is starting from rest.

By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:

y = 67.814x
