Answer : a
Sin is opposite/hypotenuse which is 8/10
And this is 4/5
-2(3x-4)=8
-6x + 8 = 8
-6x = 0
x = 0
Cot = Cos/Sin
Cos = 12/13
Sin = 5/13
Therefore, 12/3 divided by 5/13 equals 12/5
Answer is 1.
Answer:
9.68%
Step-by-step explanation:
cost of car = $35,000
down payment = $3,000
number of monthly instalments= $65
amount in every monthly instalment= $539.99
total monthly payment= 65×539.99= 35099.35
amount to be paid apart from downpayment= $35,000-3000= 32,000
therefore total interest paid in 65 months= 35099.35-3200= $3099.35
now, monthly interest rate 
⇒ r= 9.68%
1/14 in 30 mins
30 mins x 14=420 mins
420 mins in hours =7 hours
