Answer: 18 3/64 in. cubed

Step-by-step explanation:

Since the formula for solving the volume of a rectangular prism is just:

(length)(width)(height) -> you can plug in the measurements you were given

(3 1/2 in)(1 7/8 in)(2 3/4 in) -> after multiplying, you should get: 18 3/64 in cubed

Trust <3

Answer:

The first thing you should do is draw the points in the Cartesian plane and then join them to find the polygon.

The searched polygon can be seen in the attached image.

The area of the polygon will be the area of the square plus the area of the triangle.

At = (6) * (8) + (1/2) * (5) * (8) = 68

At = 68

answer

the area of the polygon is 68units ^ 2

The price of fruits per kg are given below- Watermelon Rs 18.50 Cherry Rs 72 Grapes Rs 120.60 Apples Rs 78.40 Karan bought 412 kg watermelon, 1 kg 200g cherries,250g grapes and 134 kg apples .He gave a Rs 500 note to the shopkeeper .How much money did he get back?

Answers

Answer:

[tex]X=-2.74*10^{-7}Rs[/tex]

Step-by-step explanation:

From the question we are told that:

Table for price per Kg

 Watermelon Rs 18.50

 Cherry Rs 72

 Grapes Rs 120.60

 Apples Rs 78.40

Karan Bought:

 412 kg watermelon

 1 kg 200g cherries

 250 g grapes

 134 kg apples

Generally the equation for Total Price of Fruits Bought is mathematically given by

\sum (Price Rs* Weight kg )

 [tex]\sum (P* W)=(412*18.5)+(1.2*72)+(0.25*120.60+(134*78.40))[/tex]

 [tex]\sum (P* W)=27374289.78[/tex]

Therefore the Amount of Money he gets back is

 [tex]X=500-\sum (P* W)[/tex]

 [tex]X=-2.74*10^{-7}Rs[/tex]

Therefore

He owes the shop keeper 2.74 million Rs

A cone and cylinder each have a height of 10 inches and a radius of 5 inches. If you filled the cone completely with water and poured it into the cylinder. How many times would it take until the cylinder is completely full with water?

Answers

Answer:

The times that would take until the cylinder is completely full with water by the cone are:

3 times.

Step-by-step explanation:

To identify how many times we must fill a cone to fill completely a cylinder with the same height and radius, we must calculate the volume of the two containers and next divide the volume of the cylinder by the volume of the cone. To obtain the volume of the cylinder we can use the next formula:

Volume of a cylinder = [tex]\pi[/tex] * [tex]radius^{2}[/tex] * [tex]height[/tex]

If we replace the values in the formula, we obtain:

Volume of a cylinder = [tex]\pi[/tex] *(5 inches)^2 * 10 inchesVolume of a cylinder = 785.4 inches^3 approximately.

Now, we're gonna calculate the volume of the cone with the next formula:

Volume of a cone = [tex]\frac{\pi*radius^{2}*height }{3}[/tex]

As you can see just with the formula, The volume of a cone is three times less than that of a cylinder (because we add the dividend 3 to it), but we're gonna replace and prove it:

Volume of a cone = [[tex]\pi[/tex] *(5 inches)^2 * 10 inches] / 3Volume of a cone = [785.4 inches^3] / 3Volume of a cone = 261.8 inches^3 approximately.

And, if we divide the two volumes to obtain the times we need to fill the cone to fill completely the cylinder:

Times we need to fill the cone = 785.4 / 261.8Times we need to fill the cone = 3

By this reason, you must fill completely a cone 3 times to fill completely a cylinder with the same radius and height.

5(x+2y-3) is the right answer

if a and b are roots of 3x2-6+2=0then find a+b​

Answers

Answer:

a + b =  2

Step-by-step explanation:

Given

ax² + bx + c = 0 ( equation in standard form )

Then the sum of the roots = - [tex]\frac{b}{a}[/tex]

3x² - 6x + 2 = 0 ← is in standard form

with a = 3, b = - 6 , then

sum of roots = - [tex]\frac{-6}{3}[/tex] = 2

Answer:

[tex]I \ think \ it \ is \ 6x\\\\3x^2 - 6x +2 = 0\\\\[/tex]

[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2a} \\\\a = 3, b = -6, c = 2\\\\x = \frac{-b + \sqrt{b^2 - 4*a*c} }{2a}, x = \frac{-b - \sqrt{b^2 - 4*a*c} }{2a} \\\\ \\\\x = \frac{6 + \sqrt{36 - 24} }{6} , x = \frac{6-\sqrt{36 -24} }{6} \\\\[/tex]

[tex]x = \frac{6+\sqrt{12} }{6} , x = \frac{6-\sqrt{12} }{6} \\\\x = \frac{3+\sqrt{3} }{3} , x = \frac{3-\sqrt{3} }{3}[/tex]

[tex]Let \ a = \frac{3 + \sqrt{3} }{3} , b = \frac{3-\sqrt{3} }{3} \\\\a + b = \frac{3+\sqrt{3} }{3} + \frac{3-\sqrt{3} }{3} = \frac{3+\sqrt{3} +3-\sqrt{3} }{3} = \frac{6}{3} = 2[/tex]

15 x 35

Answer:

A

Step-by-step explanation:

let width be w , then length l = w + 20

perimeter = 2w + 2l

                 = 2w + 2(w + 20) , so

2w + 2w + 40 = 100

4w + 40 = 100 ( subtract 40 from both sides )

4w = 60 ( divide both sides by 4 )

w = 15 and l = 15 + 20 = 35

Write the standard form of the equation of the circle with the graph shown to the right.

Answers

Answer:

(x+5)²+(y+5)² =4

Step-by-step explanation:

the standard equation is

(x-h)²+(y-k)²=r²

where (h, k) is the center in our case ( -5, -5) and r is the radius that in our case r=2, so substitute

(x+5)²+(y+5)²=2²

Answer:

[tex](x+5)^2+(y+5)^2=4[/tex]

Step-by-step explanation:

Hi there!

Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at (h,k) and r is the radius

1) Determine the center of the circle

On the graph, we can determine that the circle is centered at the point (-5,-5). Plug this into the equation:

[tex](x-(-5))^2+(y-(-5))^2=r^2\\(x+5)^2+(y+5)^2=r^2[/tex]

2) Determine the value of r²

In the graph, we can see that the radius of the circle is equal to 2 units. Therefore, the value of r² is 4. Plug this back into the equation:

[tex](x+5)^2+(y+5)^2=4[/tex]
