The percent decrease for 3 to .5 is 83.33%
Answer:
(2) angle1 = 139, angle2 = 41, angle4 = 41, angle5 = 139, angle6 = 41, angle7 = 139, angle8 = 41
(3) angle1 = 150, angle2 = 30, angle4 = 30, angle5 = 150, angle6 = 30, angle7 = 150, angle8 = 30
Step-by-step explanation:
All angle are either equal to each other or supplementary. I use corresponding angles and vertical angles to prove each of the above.
For number 3, angle 3 and angle 8 are supplementary, so they add up to 180:
8x +70 + (4x - 10) = 180
12x + 60 = 180
12x = 120
x = 10
So if x = 10, then 8x + 70 = 8(10) + 70 = 150
That means all angles are either 150 or 30 for number 3.
Isn't it 1/8?
I hope this helped i think i just simplified xD
Answer: It is 86 because it says lowest and greater than

Answer:
Step-by-step explanation:
The pressure exerted by an object is given by:
where
F is the magnitude of the force
A is the area of the surface perpendicular to the force
In this problem, the force is the weight of the books + the shelf, which is given by
where
m = 262 kg is the total mass
is the acceleration of gravity
Substituting,
The area of the four legs is:
Therefore, the pressure exerted on them is:
