Choose the best estimate for the division problem below.

Sveta_85 [38]

Answer:

The estimated answer would be 9

Step-by-step explanation:

The answer I received in the calculator was 8.94422. Since the tenths, place value(9) is closer to 9.0 than 8.0, we round up. I hope this helps you.

Write the slope-intercept form of the equation of the line through the given point with the given slope

Troyanec [42]

Answer:

y = M X + B

Step-by-step explanation:

y - y1 = m (x - x1)

x1 = 2

y1 = 5

m = 1/7

y - 5 = (1/7) (x - 2)

3. Diego drew a scaled version of a Polygon P and labeled it Q.

bogdanovich [222]

Answer:

The scale factor used to go from P to Q is 1/4

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z ----> the scale factor

x -----> area of polygon Q

y -----> area of polygon P

$z^{2}=\frac{x}{y}$

we have

$y=72\ units^2$

Find the area of polygon Q

Divide the the area of polygon Q in two triangles and three squares

The area of the polygon Q is equal to the area of two triangles plus the area of three squares

see the attached figure N 2

Find the area of triangle 1

$A=(1/2)(1)(2)=1\ units^2$

Find the area of three squares (A2,A3 and A4)

$A=3(1)^2=3\ units^2$

Find the area of triangle 5

$A=(1/2)(1)(1)=0.5\ units^2$

The area of polygon Q is

$x=1+3+0.5=4.5\ units^2$

Find the scale factor

$z^{2}=\frac{x}{y}$

we have $y=72\ units^2$

$x=4.5\ units^2$

substitute and solve for z

$z^{2}=\frac{4.5}{72}$

$z^{2}=\frac{1}{16}$

square root both sides

$z=\frac{1}{4}$

therefore

The scale factor used to go from P to Q is 1/4

Triangle PQR is a right triangle. if PQ= 8 , what is PR?

Norma-Jean [14]

It is 30-60-90 triangle, so:

$PR=\dfrac{PQ\cdot\sqrt{3}}{2}=\dfrac{8\cdot\sqrt{3}}{2}=\boxed{4\sqrt{3}}$

Answer B.
