The scale 0.5 in : 6 ft, means that
any distance of 0.5 in on paper, represents 6 ft in reality
for example:
0.5*2= 1(in) represents 6*2=12 (ft)
0.5*4= 2(in) represents 6*4=24 (ft)
0.5*10=5(in) represents 6*10=60 (ft) and so on...
Let the wall be x (in) in the drawing:
0.5 (in) represents 6 (ft),
x (in) represents 30 (ft)
----------------------------------------
thus x = (0.5*30)/6 = 15/6= 2.5 (in)
Answer: 2.5 in
the y-intercept is 9 and the x-intercept is -18
The answer is 400 because u multiply 8 x 10= 80 x 5=400

Answer:
2440 km; 1.330 × 10²⁷ kg
Step-by-step explanation:
(a) <em>Radius of Mercury
</em>
D = 4.88 × 10^³ km
D = 2r Divide each side by 2
r = D/2
r = (4.88 × 10³)/2
r = 2.44 × 10³ km Convert to decimal notation
r = 2440 km
(c) <em>Mass difference
</em>
Difference = 1.898 × 10²⁷ - 5.68 × 10²⁶ Rationalize exponents
Difference = 1.898 × 10²⁷ - 0.568 × 10²⁷
Difference = 1.330 × 10²⁷ kg
