Answer:

0.45 m, 0.63 m, 0.72 m

Step-by-step explanation:

Let the three parts of the line be 5x, 7x and 8x

Therefore,

5x + 7x + 8x = 1.8

20x = 1.8

x = 1.8/20

x = 0.09

5x = 5*0.09 = 0.45 m

7x = 7*0.09 = 0.63 m

8x = 8*0.09 = 0.72 m

HELP PLEASEE!!! I just need help with the 2 boxes

Soloha48 [4]

Answer:

$y= x - 300$

$y = -246$ -- Her equivalent weight on earth

Step-by-step explanation:

Given

The attached table

Required

Fill in the gaps

(a) The equation

First, we calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

From the table, we can say that:

$(x_1,y_1) = (0,-300)$

$(x_2,y_2) = (300,0)$

So, we have:

$m = \frac{0 -(-300)}{300 - 0}$

$m = \frac{0 +300}{300}$

$m = \frac{300}{300}$

$m = 1$

The equation is then calculated using:

$y - y_1 = m(x - x_1)$

This gives:

$y - (-300) = 1(x - 0)$

$y +300 = 1(x)$

$y +300 = x$

$y= x - 300$

(b) When x = 54

Substitute 54 for x in $y= x - 300$

$y = 54 - 300$

$y = -246$
