Answer:
start by dividing the arc's central angle in degrees by 360, multiply that number by the radius of the circle, and then multiply that number by 2 × pi to find the arc length.
Step-by-step explanation:
The quadratic formula is
If the square root in the numerator is equal to 0, we are left with
when you do the plus or minus, the answers will be the same since you are adding and subtracting 0. Therefore there will be two identical rational solutions.
Here are the resulting percentages:
LEAH = 3.5%
RATHA = 2.3%
ED = 1.8%
CHRIS = 4.2%
MARY = 2.5%
You arrive at this answer by dividing the bonus by the wages
BONUS/WAGE = PERCENTAGE OF BONUS TO WAGE.
Chris had the greatest percentage of wages in his bonus
Answer:
There 138 quarters and 0 nickels.
The value of nickels is $0.
Step-by-step explanation:
A quarter is 0.25 of a dollar, and a nickel is 0.05 of a dollar. We are told that the total worth of nickels and dollars we have is 34.5, that is
where is the number of quarters, and is the number of nickels.
We are also told that total number of coins is 138, that is
so we have two equations:
To this system of equations we first solve for in second equation and substitute its value into the first equation:
the first equation becomes
So we have 138 quarters.
Now we put this value into equation(2) and solve for
So we have 0 nickles and therefore their value is $0.
180 - 85 = 95
180 - 145 = 35
A = 180 - 95 - 35
A = 50
