A picture is worth a thousand words. It's also worth a thousand data points!

A graph can be defined as :

a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.

The different uses of graphs are :

Line graphs can be used to compare changes over the same period of time for more than one group. Pie charts are best to use when you are trying to compare parts of a whole. They do not show changes over time. Bar graphs are used to compare things between different groups or to track changes over time.

Other uses of graphs are :

It can show patterns. Like a declining sales line.

It can easily show the breakdown of costs as in a Pie Chart.

It can determine profit and loss in a breakeven analysis.

It can show a comparison of two different processes.

Tina ate 21 starbursts. If she ate 35% of the package of Starbursts, how many Starbursts are in the package?

mojhsa [17]

Answer:

60 starbursts

Step-by-step explanation:

We can set up an equation to find the answer. 21/x=0.35/1 because we're trying to find how many starbursts make up 100% of the package. So then to solve, we take 21x1 and then divide that by 0.35. From this we find that x=60.

Two boards, one four inches wide and the other six inches wide, are nailed together to form an X. The angle at which they cross

Sunny_sXe [5.5K]

Answer:

The area of the unpainted region on the four inch board = 160·√3 in.²

Step-by-step explanation:

Here we have that the boards are crossing each other on their flat sides Therefore, when the boards are separated, the area of the unpainted region is the area of a parallelogram

The dimensions of the formed parallelogram are;

Interior angles = 60° and 120° (adjacent angles of a parallelogram)

Height, h of parallelogram formed = 4 inches

From the angle of crossing of the parallelogram, we have;

Angle between the width or perpendicular cross section of the 6 inches board and the angle of crossing of the two boards = 90° - 60° = 30°

Therefore, length of base, b of the parallelogram formed by the unpainted region is given as follows;

$b = \frac{60}{cos(30)} = 40\cdot \sqrt{3} \ inches$
