Answer:

C = (\frac{33}{5},\frac{19}{5})

Step-by-step explanation:

Given

A = (1,3)

B = (8,4)

AC : BC = 4 : 1

Required

Determine the coordinates of C

To do this, we make use of:

C = (\frac{nx_1 + mx_2}{n+m},\frac{ny_1 + my_2}{n+m})

Where:

A = (1,3) ---- (x_1,y_1)

B = (8,4) ---- (x_2,y_2)

m:n = 4 : 1

So:

C = (\frac{1 * 1 + 4*8}{1+4},\frac{1*3 + 4*4}{1+4})

C = (\frac{33}{5},\frac{19}{5})

Answer:

Step-by-step explanation:

1) 30 : 100 = x : 299

x = (30 x 299)/100

x = 89,70 $

2) 299 - 89,70 = 209,30 $

3)  5 : 100 = x : 209,30

x = 10,465 $

209,30 + 10,465 = 219,77 $
