Answer:

Your question was a bit confusing so I found another related question. You can reference it with your own details.

A vendor bought 10 dozen eggs at the rate of Rs 22 per dozen. Six of the eggs were rotten. He sold the remaining eggs at the rate of Rs 2.50 per egg . Find his profit or loss

Vendor bought 10 dozen eggs which means the vendor bought:

= 10 * 12 eggs

= 120 eggs

6 were rotten and he sold the rest for Rs. 2.50 per egg.

= (120 - 6) * 2.5

= Rs. 285

The amount he spent on the eggs was:

= 10 dozen * 22

= Rs. 220

Profit = 285 - 220

= Rs. 65

What number is 24% of 80

jonny [76]

Hi

24% of 80 is 19.2

100% ⇒ 80
24% ⇒ x

100x = 24·(80)
100x = 1920
x = 1920/100
x = 19.2

Which of the following equations will produce the graph shown below?

melisa1 [442]

The graph is a circle, centered at the origin, with radius=4.

We know that we can write the equation of a circle with radius r and center (a,b) as :

$(x-a)^2+(y-b)^2=r^2$ .

Thus, substituting (a, b) with (0, 0) and r with 4, we have:

$x^2+y^2=16$ .

The solutions of this equation are all the points forming the circle shown in the picture. The solutions of this equation are still the same even if we multiply both sides of the equation by 2, because rewriting the equation as:

$x^2+y^2=16\\\\x^2+y^2-16=0\\\\2(x^2+y^2-16)=0$ ,

we would still have the same roots.

Thus, the equation of the circle can be written as :

$2x^2+2y^2=32$ .

Find the area of the shaded polygons:

tigry1 [53]

Answer:

Step-by-step explanation:

Purple: This makes two trapezoids. A=(a+b)/2 times h

1st = (4+1)/2 x 1 = 2.5

2nd = (4+1)/2 x 3 = 5/2 x 3 = 2.5x3=7.5

Total = 2.5+7.5=10

Green: if you draw a line down the center, you can divide these into two more manageable triangles. A=1/2bh

1st = 1/2x2x2 = 2

2nd = 1/2x2x2 = 2

Total = 2+2=4

7. The jib sail of a yacht is

Rom4ik [11]

Answer:

Pytagora's Theorem

Step-by-step explanation

a = 4 m

b = 15 m

c = ?

a^2 + b^2 = c^2

√ a^2 + b^2 = c

a^2 = 16 m

b^2 = 225 m

√ 16 + 225 = c

√ 241 = 15.52 m

c = 15.52 m
