It would take one person twice the time so a) 12 hours
12/3 is 4 so b) 4 hours
Answer:
x = 4
Step-by-step explanation:
Step 1: Write out the expression
5(2x - 9) = -5
Step 2: Solve for <em>x</em>
10x - 45 = -5
10x = 40
x = 4
Answer:
no
Step-by-step explanation:
x and 114° are same- side interior angles and are supplementary, then
x = 180 - 114 = 66
Minimum payment
= 3% of $1240
= 3/100 x 1340
= $40.20
Answer:
The velocity of the car after the collision is -5.36 m/s
Step-by-step explanation:
An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same.
let the following:
m₁ = mass of the car = 1400 kg
m₂ = mass of the truck = 3200 kg
u₁ = velocity of the car before collision = 13.7 m/s
u₂ = velocity of the truck before collision = 0 m/s
v₁ = velocity of the car after collision
v₂ = velocity of the truck after collision
v₁ = [ u₁ * (m₁ - m₂) + u₂ * 2m₂ ]/ (m₁ + m₂)
= [ 13.7 * (1400 - 3200) + 0 * 2 * 3200 ]/ (1400 + 3200)
= - 5.36 m/s
So, <u>the velocity of the car after the collision is -5.36 m/s</u>
