A fruit seller brought 120 oranges for rs 500 and spent rs 60 for parking them into 10 boxes each containing a dozen oranges. If he sold a dozen of oranges for rs 58.8, find the profit percentage I know the answer it is 5% but I need the explanation for it in picture format it is also ok but in neat handwriting pls help
Answers
Answer:
First, we know that he spent rs500 plus rs60 in the whole process, then the total cost is:
C = rs500 + rs60 = rs560
Now he sells the oranges in packs of 12, then if he has 120 oranges, the total number of packs that he can sell is:
120/12 = 10
So he has 10 packs of 12 oranges.
And he sells each one for rs58.8
Then if he sells the 10 packs, the total revenue is:
R = 10*(rs58.8) = rs588
The profit is the difference between the revenue and the cost, here the profit is:
P = R - C = rs588 - rs560 = rs28
And the profit percentage is calculated as follows:
(P/C)*100%
Where P = profit and C = cost, then we have:
(rs28/rs560)*100% = 5%

Ken had 80 rubber bands, he sold 10 and 10
got damaged. How many good rubber bands
were left with Ken? What percentage of
rubber bands were left?
Answers
He has 75% of his rubber bands left.
Answer:
60 were left with Ken, and that is 75%
Step-by-step explanation:
80-10 = 70
70-10 = 60
60/80 = x/100, simplify & cross multiply
6/8 = x/100
600 = 8x
x = 75
Use the Triangle Inequality Property to determine whether a triangle can be formed with the given side lengths. 4 m, 8 m, 9 m *
Answers
Answer:
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.
The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:
a + b > c; a + c > b; b + c > a
Given a triangle with side length 4 m, 8 m, 9 m:
4m + 8m = 12m > 9m
4m + 9m = 13m > 8m
8m + 9m = 17m > 4m
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

A central angle 0, in a circle of radius 4 ft intercepts an arc length of 50 ft.
Calculate the radian measure of 0.
Answers
Given:
The central angle = [tex]\theta[/tex]
Radius of the circle = 4 ft
Intercepted arc length = 50ft
To find:
The value of [tex]\theta [/tex] in radian measure.
Solution:
The formula for arc length is
[tex]s=r\theta[/tex]
where, r is radius and [tex]\theta [/tex] is the central angle in radians.
Putting s=50 and r=4, we get
[tex]50=4\theta[/tex]
Divide both sides by 4.
[tex]\dfrac{50}{4}=\theta[/tex]
[tex]12.5=\theta[/tex]
Therefore, the value of [tex]\theta [/tex] is 12.5 radians.

Step-by-step explanation:
450 / 2 = 225
1 mile = 1,760
225 * 1,760 = 396,000 yd
Plz mark as brainliest if this helped! Have a nice day!!!
-Lil_G
Step-by-step explanation:
450 miles = 1hour = 60mins
X miles = 30mins
cross multiply
450 × 30 = 60 × X
13500 = 60X
divide through by 60
225 = X
therefore, X = 225miles
now
1 mile= 1760 yards
225 miles = X
cross multiply
X = 1760 ×225
X = 396000 yards

y = 2(x - 1)² + 4
y = 2(x² - 2x + 1) + 4
y = 2x² - 4x + 2 + 4
