Answer:

y = 7/6 * x - 1/6

Step-by-step explanation:

6x + 7y = 126

y = (- 6/7) * x  + 18

slope: -6/7

A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line

slope' : 7/6

y = mx + b

8 = 7/6 * 7 + b

b =  (48-49) / 6 = - 1/6

equation: y = 7/6 * x - 1/6

tan(x) = 10/60

tan(x) = 1/6

tan(x) = a -> x = arctan(a) + πn

x = arctan(1/6) + πn

x = 0.165 + πn

Best of Luck!

Round to the nearest gram
earnstyle [38]

Alright, so after a half-life, half of the previous number would be left. So basically,

180 g ← 0 half lives

90 g ← 1 half life

45 g ← 2 half lives

22.5 g ← 3 half lives

11.25 g ← 4 half lives


Therefore, the answer is 11.25 grams
