Step-by-step explanation:
To find the amount of profit earned in each product,apply the percent profit formula;
%profit= profit/original price *100
<u>a)Candy </u>
% Profit =65%
Selling price = $6400
This means;
165%=6400
100%=?
Cross multiply
(100*6400)/165 =$3878.80
Original price= $3878.80
Profit= $6400-$3878.80
=$2521.20
<u>b)Wrapping Paper</u>
%profit= 40%
Selling price= $1200
This means;
140%=$1200
100%=?
Cross-multiply
(1200*100)/140=$857.14
Original price=$857.14
Profit=$1200-$857.14
=$342.90
<u>c)Stationery</u>
%profit= 50%
Selling price =$900
This means;
150%=900
100%=?
Cross-multiply
(900*100)/150 = $600
Original price = $600
Profit= $900-$600=$300
<u>d)Calender's</u>
%Profit=25%
Selling price=$3120
This means;
125%=$3120
100%=?
Cross-multiply
(100*3120)/125=$2496
Original Price=$2496
Profit= $3120-$2496=$624
2)
Selling price for pens and pencils =$4500
%percent profit earned = 42%
Profit earned will be:
142% = $4500
100%=?
Cross-multiply
(100*4500)/142 =3169.01
Original price=$3169.01
Profit= $4500-$3169.01
=$ 1331

Answer:
The time of responding.
Step-by-step explanation:
Dependent variable is the variable that is being measured during an experiment to determine the effect of changes that occurs. It is also known as the responding variable and it depends sorely on the things that happens when an experiment is being carried out. It always depends on the independent variable.

Answer: Choice C. (x+1)(x-5)</h3>
We need to find two numbers that
- Multiply to -5 (last term)
- Add to -4 (middle coefficient)
Through trial and error, those two numbers are 1 and -5
- 1 times -5 = -5
- 1 plus -5 = -4
So this means x^2-4x-5 factors to (x+1)(x-5)
This is the same as (x-5)(x+1) since the order of multiplication doesn't matter.
Answer:
Step-by-step explanation:
substitute x = r*cos(θ), y = r*sin(θ) ==> r²(cos²(θ) + sin²(θ)) = 2r²cos(θ)sin(θ). Cancel the r² on both sides. On the left, use pythagorean identity cos²(θ) + sin²(θ) = 1. On the right apply double angle identity sin(2θ) = 2cos(θ)sin(θ).
This yields 1=sin(2θ). (I assume you meant to type sin(2θ) on the right hand side of the equation).
