A. If it has a 60% mark up price of $120 that would be $60 so the total would be $180. B. If there selling the bike at what the store is selling it for it would be $126 because 30% of $180 is $54 so subtract $54 from $180 and you will get $126 C. The store would make a total profit of $6.
Answer:
a) T = 20.601 N
b) T = 9.4585 N
Step-by-step explanation:
The tension in the string if the 5.8 kg box is held in place, so that it cannot move can be obtained as follows
For m = 2.1 Kg
∑ Fy = 0
T - W = 0 ⇒ T = W = m*g
⇒ T = 2.1 Kg*9.81 m/s²
⇒ T = 20.601 N (↑)
The tension in the string once the box begins to move can be obtained as follows
For M = 5.8 Kg
∑ Fx' = M*a
where x' is the direction of the slope
then
∑ Fx' = M*a ⇒ <em>T - M*g*Sin ∅ = M*a (I)</em>
For m = 2.1 Kg
∑ Fy = m*a
⇒ T - W = m*a
⇒ <em>T - m*g = m*a (II)</em>
If we solve the system of equations that comprises <em>I</em> and <em>II</em> we will know T:
T = M*m*g*(Sin ∅ -1) / (m - M)
⇒ T = (5.8 Kg)(2.1 Kg)(9.81 m/s²)(Sin 45º - 1) / (2.1 Kg - 5.8 Kg)
⇒ T = 9.4585 N
The "D" is the correct answer
Answer: $35.75
Step-by-step explanation:
1) $25 for the manicure
2) $25*(0.20) = $5 for the tip
3) $5.75 for the tip
$25 + $5 + $5.75 for the total
$35.75 total
