Answer:
1. D
2. C
3. C
4. D
5. B
Step-by-step explanation:
1. 20 times 3/5 equals 12
2. 1/5 times 8 equals 8/5 or 1 3/5
3. 2/3 of 93 equals 62
4. 3/5 of 30 equals 18
5. 2/3 times 5 equals 10/3 or 3 1/3
Answer:
A, C
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
the ∠A is adjacent (adj) to AB and opposite (Opp) of BC and AB is the hypotenuse (Hyp) of the triangle
which one of the above trig functions fits that?
sin(Ф) = BC / AC is sin(Ф)= Opp / Hyp , so choice A) works
cos(Ф) = BC / AC is not cos(Ф) = Opp / Hyp so choice B) does not work
cos(Ф) = BA / AC is cos(Ф) = Adj / Hyp so choice C) works
AC / BC is just a ratio it's not the angle , so D) doesn't work
Answer:
no
Step-by-step explanation:
The interest on the loan is
.. I = P*r*t = 3000*.09*180/365 = 133.15
Your effective rate is
.. r = I/(Pt) = (100 +133.15)/(3000*180/365) = 15.8%

⇒ 8 - z = 7
⇒ 8 - 7 = z
⇒ 1 = z
