m₁ = mass hanged initially = 0.2 kg
x₁ = initial stretch in the spring = 8 cm = 0.08 m
k = spring constant of the spring
the weight of the mass hanged is balanced by the spring force by the spring hence
Spring force = weight of mass hanged
k x₁ = m₁ g
k (0.08) = (0.2) (9.8)
k = 24.5 N/m
m₂ = mass hanged later = 0.5 kg
x₂ = final stretch in the spring = ?
k = spring constant of the spring = 24.5 N/m
the weight of the mass hanged is balanced by the spring force by the spring hence
Spring force = weight of mass hanged
k x₂ = m₂ g
(24.5) x₂ = (0.5) (9.8)
x₂ = 0.2 m = 20 cm
All of the angles add up to 360 degrees.
180(4-2) = 360
9x+1+5x-12+8x+61
Add up all the like terms
22x+50= 360
x=14.1
We are going to add up all of the angles together and subtract them by 360 in order to find the measurement of the missing angle.
Angle C: 9(14.1) + 1 = 127.9
Angle D: 5(14.1) - 12 = 58.5
Angle A: 8(14.1) + 61 = 173.8
All of these angles add up to 360
This means that angle D is 0 degrees since all of the other angles already add up to 360.
<u>Answer</u>
0 degrees
Answer:
1. 9 * 5 in.
2. 3 * 15 in.
Step-by-step explanation:
Volume = 1/3 * area of the base * height
120 = 1/3 * A * 8
So A = 120 / (8/3)
= 120 * 3/8
= 45 in^2.
So the dimensions of the base could be 9 * 5 in
or 3 * 15 in.
