Answer:
x = 1
Step-by-step explanation:
We have to solve the given logarithmic equation of variable x.
The equation is
⇒
{Since, we know the logarithmic property, }
⇒
{Since we know that }
Now cancelling log from both sides we get,
⇒
⇒ x = 1 (Answer)
The area of the shaded portion = 100.48 cm²
Solution:
Radius of the inner circle = 2 cm
Radius of the outer circle = 6 cm
Area of the inner circle =
Area of the inner circle = 12.56 cm²
Area of the outer circle =
Area of the outer circle = 113.04 cm²
Area of the shaded portion = Area of the outer circle – Area of the inner circle
= 113.04 cm² – 12.56 cm²
= 100.48 cm²
Hence the area of the shaded portion = 100.48 cm²
It is given in the question that,
Julio is paid 1.2 times his normal hourly rate for each hour he works over 29 hours in a week. Last week he worked 34 hours and earned $434.00.
And Julio's normal hour rate is r.
So the earning equation is
This is reasonable, because working 34 hours with a rate of $12 per hour is
And $408 is close to $434.
