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
Answer:
Step-by-step explanation:
f(-2)= 4(-2)^2 + 3 = 4(4) + 3 = 16 + 3 = 19
g(19) = 3(19) + 2 = 57 + 2 = 59
g(-2)= 3(-2) + 2 = -6 + 2 = -4
f(-4)= 4(-4)^2 + 3 = 64 + 3 = 67
Answer:
12
Step-by-step explanation:
Step-by-step explanation:
1. 18^2 - 10^2 = 324 - 100 = 224
Sqt(224)=14.9666
Approximate = 14.97
2. 100 - 16 = 84
Sqrt 84 = 9.1652
Approximate = 9.17
3. 225 - 49 = 176
Sqrt 176 = 13.2665
Approximate = 13.27
4. 361 - 144 = 217
Sqrt 217 = 14.7309
Approximate = 14.73
