Answer:
1%
Step-by-step explanation:
The selling price for each radio is $2288.
Total selling price is 
$4576.
Profit is 10%.
Loss is also 10%.
Cost price=
Cost price=
Utilizing the formula,
Cost price of the first radio is 
$2080.
Cost price of the second radio is 
=$2542.2.
The combined cost price for both radios totals 2080+2542.2=$4622.2.
Total cost price exceeds total selling price.
Loss equals selling price minus cost price.
Loss is calculated as 4622.2-4576=$46.2.
Loss%=
Loss percentage is 
1%.
Thus, the loss is 1%.
To find the hypotenuse of a right triangle with sides measuring 3 and 4, we first need to use the Pythagorean theorem and then add that distance to 3 and 4.
By applying the theorem, the square of the hypotenuse equals the sum of the squares of the sides...
d^2=3^2+4^2
d^2=9+16
d^2=25
d=√25
d=5
Thus, the total distance for her run is 5+4+3=12 km
(5r - 4)(r² - 6r + 4)
uses the distributive property for multiplication.
This expands to 5r(r² - 6r + 4) - 4(r² - 6r + 4)
which results in 5r³ - 30r² + 20r - 4r² + 24r - 16
as you combine like terms and simplify.
The outcome is 5r³ - 30r² - 4r² + 20r + 24r - 16
leading to a final expression of 5r³ - 34r² + 44r - 16. Choice A.
