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.
6.6. 2.2*3= 6.6
i hope this makes since
Answer:
4.45 or 4 so b
Step-by-step explanation:
Answer: x = the quantity of 5 plus or minus the square root of 29 all over 2
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 5x - 1 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the given quadratic equation,
a = 1
b = - 5
c = - 1
Therefore,
x = [- - 5 ± √(- 5² - 4 × 1 × - 1)]/2 × 1
x = [5 ± √(25- - 4)]/2
x = [5 ± √29]/ 2
x = ( 5 + √29)/- 2 or x = (5 - √29)/2
