The salesperson tells Ben that Motorcycle A produces {288}\ \text{ J} 288 J
of kinetic energy and {312}\ \text{ J}
312 J
of heat and sound energy when {600}\ \text{ J}
600 J
of chemical potential energy is supplied to it.
Motorcycle B produces {400}\ \text{ J}
400 J
of kinetic energy and {200}\ \text{ J}
200 J
of heat and sound energy for the same amount of chemical potential energy.

Help Ben decide which motorcycle to buy through calculating the energy efficiency of each of them.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

you go to prefence in the settings and youll see a "i want to delete my account.
