Answer:
Considering the Product and the Power rule of the Logarithms, they're both equivalent for x >0
Step-by-step explanation:
1) Considering the Product and the Power rule of the Logarithms:
2) Therefore we can say that:
Answer:
Market price $400
Cost price $300
Step-by-step explanation:
MP: market price
CP: cost price
1. (MP x 0.9) - CP = 60
CP = 0.9MP - 60
2. MP - CP = 100
CP = MP - 100
0.9MP - 60 = MP - 100
MP - 0.9MP = 100 - 60
0.1MP = 40
MP = 400
Cost price = MP - 100 = 400 - 100 = 300
First, use the equation for circumference:
c= 2πr
now plug in what you know:
c= 2π(4.5)
c= 9π
Answer:
A. $1
Step-by-step explanation:
If he played WinOne 100 times, it means that he spent $200. If he won the lottery twice it means that he won $300 in total. We know that the earnings is given by the difference between the money won and the money spent.
Earnings = Won - Spent
Earnings $100.
Now, the net winning per turn is given by the division between the earnings and the number of times played:
Net winning per turn = $100/100 = $1
Therefore, he net winning per turn is $1.
Answer:
8.88
Step-by-step explanation:
With reference angle 42°
hypotenuse (h) = 12
base (b) = x
Now
cos 42° = b / h
0.74 = x / 12
x = 0.74 * 12
x = 8.88
