Actually Welcome to the Concept of the Algebric Operation,

here, m=-3 and n=7

, after substituting we get as,

(7-(-3))*2

=> (7+3)*2

=>10*2

=>20

hence, final answer is 20

Annie is filling flower pots with soil. Each flower pot is shaped like a cylinder. Just like the one here below. The radius is 2
Anna [14]

Answer:

  • None

Step-by-step explanation:

<u>Given:</u>

  • Radius r = 2 in =  2*2.54 cm = 5.08 cm
  • Height h = 6 in = 6*2.54 cm = 15.24 cm
  • Volume of soil V = 200 cm³

<u>Find the volume of one pot:</u>

  • V = πr²h
  • V = 3.14*5.08²*15.24 = 1234.92 cm³

From the number above we see the volume of each pot is greater than the volume of soil Ann has, so she can't fill any.

The answer is zero

<em>Note. If the volume unit of soil was in³ the answer would be different</em>

Spaceship Earth, a spherical attraction at Walt Disney World’s Epcot Center, has a diameter of 50 meters. Find the surface area
Black_prince [1.1K]

The surface area of Spaceship Earth is: 7850 m^2

Step-by-step explanation:

Given

Diameter of spherical structure = d = 50 meters

As the attraction is in the form of a sphere, its radius will be used to find the surface area.

Radius = r = \frac{d}{2} = \frac{50}{2} = 25\ m

The formula for surface area of sphere is:

SA = 4\pi  r^2\\= 4 * 3.14 * (25)^2\\= 4*3.14*625\\=7850\ m^2

The surface area of Spaceship Earth is: 7850 m^2

Keywords: surface area, sphere

Tickets to the movies are $7 for adults and $4 for children. If 272 tickets
rewona [7]

Answer:

202 tickets for adults were sold and 70 tickets for children are sold.

Step-by-step explanation:

Solve this question using simultaneous linear equation.

•Let the number of tickets sold for adults be a

•Let the number of tickets sold for children be b

The question stated that 272 tickets were sold altogether. So:

a + b = 272

Now, make sure that only one of the unknown values remain on the left hand side. For example:

a = 272 - b

I will refer to the above equation as equation 1.

Now, the question also stated that the tickets sold $1694. This means that:

7a + 4b = 1694

I will refer to this equation as equation 2.

Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:

7(272 - b) + 4b = 1694

Then just solve the equation by finding the value of b.

7(272 - b) + 4b = 1694 \\ 1904 - 7b + 4b = 1694 \\ 1904 - 3b = 1694 \\ 1904 - 1694 = 3b \\ 210 = 3b \\ b = 210 \div 3 \\  = 70

Lastly, find the value of a. Just take the value of b and then substitute into equation 1.

a  = 272 - b \\  = 272 - 70 \\ a = 202
