In order to derive the base of a triangle from its area, you need its height as well.

In fact, if we solve the area formula for the base, we have

$A=\dfrac{bh}{2} \iff 2A = bh \iff b=\dfrac{2a}{h}$

So, the base length would be

$b=\dfrac{2\cdot 28.7}{h} = \dfrac{57.4}{h}$

where h is the height relative to the base you're interested in.

Graph the linear equation with 3 points

barxatty [35]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x-y=1$

To graph the line find the intercepts

step 1

Find the y-intercept (value of y when the value of x is equal to zero)

For x=0

substitute in the linear equation

$0-y=1\\y=-1$

The y-intercept is the point (0,-1)

step 2

Find the x-intercept (value of x when the value of y is equal to zero)

For y=0

substitute in the linear equation

$x-0=1\\x=1$

The x-intercept is the point (1,0)

step 3

Find a third point

<em>Note</em>: It is important to specify that two points are sufficient to draw a line

assume the value of x=5

substitute in the linear equation and solve by y

$5-y=1\\y=5-1\\y=4$

The third point is (5,4)

step 4

Plot the points and connect them to graph the line

What is 150% of 3000? Round to the nearest hundredth

marin [14]

We want to find 150% of 3000. since 150% is greater than 100%, it is expected that 150% 0f 3000 will also be greater than 3000.

$150\text{\% of 3000 }=\frac{150}{100}\times3000=4500$

Therefore, 150% of 3000 is equal to 4500.

Question is Incomplete; Complete question is given below;

During a recent rainstorm, 8 centimeters of rain fell in Dubaku's hometown, and 2.36 centimeters of rain fell in Elliot's hometown. During the same storm, 15.19 centimeters of snow fell in Alperen's hometown. How much more rain fell in Dubaku's town than in Elliot's town?

Answer:

The rain fell 5.64 cm more in Dubaku's town than in Elliot's town.

Step-by-step explanation:

Given:

rain fell in Dubaku's hometown = 8 cm

rain fell in Elliot's hometown = 2.36 cm

snow fell in Alperen's hometown = 15.19cm

We need to find how much more rain fell in Dubaku's town than in Elliot's town.

Solution:

Now we can say that;

to find how much more rain fell in Dubaku's town than in Elliot's town we will subtract rain fell in Elliot's hometown from rain fell in Dubaku's hometown.

framing in equation form we get;

Amount of rain fell more in Dubaku's town than in Elliot's town = $8-2.36 = 5.64\ cm$
