Hey!

------------------------------------------------

Answer: B) half the original number

------------------------------------------------

Examples:

Multiply a number by 0.5 is the same thing as diving it by 2.

10 x 0.5 = 5

20 x 0.5 = 10

30 x 0.5 = 15

40 x 0.5 = 20

50 x 0.5 = 25

Write the equation of the line that passes through the points (5,0) and (-6, -1).

jonny [76]

Answer:

The equation in point-slope form is: $\mathbf{y=\frac{1}{11}x-\frac{5}{11} }$

Step-by-step explanation:

We need to find equation of line in point slope form that passes through points (5,0) and (-6, -1).

The general equation of point slope form is: $\mathbf{y-y_1=m(x-x_1)}$

where m is the slope of line.

We need to know Slope m

Finding Slope m

Finding Slope m using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}$

We have $x_1=5, y_1=0, x_2=-6 \ and \ y_2=-1$

Putting values and finding slope

$Slope=\frac{-1-0}{-6-(5)}\\Slope=\frac{-1}{-6-5}\\Slope=\frac{-1}{-11}\\Slope=\frac{1}{11}$

So , slope m is: $\mathbf{m=\frac{1}{11}}$

Using point (5,0) and slope m =1/22 the equation of point-slope form is:

$y-y_1=m(x-x_1)\\y-0=\frac{1}{11} (x-5)\\y=\frac{1}{11}x-\frac{5}{11}$

So, the equation in point-slope form is: $\mathbf{y=\frac{1}{11}x-\frac{5}{11} }$

Find the area. The figure is not drawn to scale

poizon [28]

Answer:

96 square inches.

Step-by-step explanation:

From given picture we see that

BC=8 in

AD=10 in

Given that

AD=AB

Then AB=10 in

Apply Pythagorean theorem in triangle ABC to find AC

$(hypotenuse)^2=(base)^2+(perpendicular)^2$

$(AB)^2=(BC)^2+(AC)^2$

$(10)^2=(8)^2+(AC)^2$

$100=64+(AC)^2$

$100-64=(AC)^2$

$36=(AC)^2$

take square root

$6=AC$

Then area of triangle ABC $=\frac{1}{2}\left(base\right)\left(altitude\right)$

$=\frac{1}{2}\left(8\right)\left(6\right)=24$

There are total 4 congruent triangles.

Then total area of the given figure = 4(24)=96 square inches.
