Kapil needed to buy a long wooden beam. He went to two sawmills that each charge an initial fee plus an additional fee for each

matrenka [14]

Answer: first sawmill charges more for each meter of wood. And first mill has a cheaper price for 5-meter wooden beam.

Step-by-step explanation:

P=5+20x. The first sawmill charges $20. Then 110-20/5-0=18 Which means The second sawmill charges $18 for each meter of wood. Since 20>18 The first sawmill charges more for each meter of wood.

P = 5+20x

=5+20x•5

= 105

The first mill charges $105 For a 5 meter beam while the second beam charges $110

△FOD~△HOG. Identify the coordinates of D and the scale factor. HELP PLEASE!!

cupoosta [38]

Answer:

Option D. $(0,-20/3)$ , $\frac{2}{3}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

$\frac{OH}{OF}=\frac{OG}{OD}$

substitute values and solve for OD

$\frac{6}{4}=\frac{10}{OD}$

$OD=10*4/6=20/3$

therefore

the coordinate of point D is $(0,-20/3)$

the scale factor is equal to $\frac{OF}{OH}=\frac{4}{6}=\frac{2}{3}$

What are the coordinates of point b on ac such that ab=2/5ac

son4ous [18]

Answer:

$(-\frac{36}{7},\frac{40}{7})$

Step-by-step explanation:

Coordinates of points A and C are (-8, 6) and (2, 5).

If a point B intersects the segment AB in the ratio of 2 : 5

Then coordinates of the point B will be,

x = $\frac{mx_2+nx_1}{m+n}$

and y = $\frac{my_2+ny_1}{m+n}$

where $(x_1, y_1)$ and $(x_2,y_2)$ are the coordinates of the extreme end of the segment and a point divides the segment in the ratio of m : n.

For the coordinates of point B,

x = $\frac{2\times 2+(-8)\times 5}{2+5}$

= $-\frac{36}{7}$

y = $\frac{2\times 5+5\times 6}{2+5}$

= $\frac{40}{7}$

Therefore, coordinates of pint B will be,

$(-\frac{36}{7},\frac{40}{7})$
