Answer: A. -18.75x + 600 = 150
Clarissa's sister will have $150 left to pay after 24 weeks.
Step-by-step explanation:
Given, Clarissa's sister makes weekly installment payments for a motorized scooter she purchased from a friend.
Cost of scooter = $600
Weekly installment = $18.75
Clarissa's sister wants to know when she has $150 left to pay for the motorized scooter.
Let 'x' be the number of weeks .
Money she left to pay = (Cost of scooter ) - (Weekly installment) x (Number of weeks)
i.e. After 24 months when she has $150 left to pay for the motorized scooter.
Hence, the correct answer is :
A. -18.75x + 600 = 150
Clarissa's sister will have $150 left to pay after 24 weeks.
With respect to the given angle of 40°
AC = b, is the opposite side
AB = 10 in is the hypotenuse.
Using the rules of trigonometric ratios,
We know the ratio associating opposite & hypotenuse is sin.
So we have
Substituting the values we get
Multiplying both sides by 10 we get
b = 10 sin 40°
So
AC = 10 sin40°
First option is the right answer.
