5 multiplied by .3 is 1.5
1.5 + 18.5 = 20.
y = 9.25
Answer:
$1.35
Step-by-step explanation:
x: quarter=$0.25
y: dime=$0.10
z: nickel=$0.05
so total amount of changes
= (0.25*x)+(0.10*y)+(0.05*z)
x=3, y=5, z=2
substituting into the eqn
total = (0.25*3)+(0.10*5)+(0.05*2)
= 0.75 + 0.5 + 0.1
= $1.35
Answer:
735N
Step-by-step explanation:
According to Newton's second law;
Force = mass * acceleration due to gravity
'
Given
Mass = 75kg
Acceleration = 9.8m/s^2
Substitute into the formula;
F = 75 * 9.8
F = 735N
Hence the force required is 735N
