Step-by-step explanation:
3/4" on the blueprint correlates to 10' in reality.
the building (or barn) is 48' high.
so, what is the factor of this compared to the normed 10' ?
10×f = 48
f = 48/10 = 4.8
alright !
now ask we need to do is: apply this factor now to the blueprint scale :
3/4 × 4.8 = 3/4 × 4 8/10 = 3/4 × 4 4/5 = 3/4 × 24/5 =
= 3×24 / 4×5 = 72/20 = 18/5 =3 3/5"
the building/barn is therefore 3 3/5" tall on the blueprint.
Answer:
9 ft
Step-by-step explanation:
3*3 = 9
Answer: is 3a + b/5 if the equation is 1/5(15a+b) and is 75a+5b if it is 1*5(15a+b) I couldn’t tell if the 1 and 5 were a fraction or being multiplied.
Answer:
line
Step-by-step explanation:
you can obviously see lines in the shape
Answer:
x = 54°
y = 66°
Step-by-step explanation:
x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)
