Answer:

$\sf\longmapsto x = 4$

Step-by-step explanation:

$\sf\longmapsto \: 2x = 44$

$\sf\longmapsto \: x = 22$

Now,

$\sf\longmapsto \: \: 22 = 2 {}^{2}$

$\sf\longmapsto \: 2 \times 2$

$\sf\longmapsto \: 4$

I believe the answer would be angle O.

All you do to find this answer is rotate the 2nd figure so it matches the 1st one above it, and look to see which angles...I guess are where and which match each other.

The exterior walls and roof of a barn are to be painted. The barn is in the shape of a rectangular prism, with an isosceles tria

vlada-n [284]

Given:

The rectangular prism has a length of 25 feet, a width of 10 feet and a height 55 feet.

The triangular prism has a base length of 25 feet, a height of 8 feet, and a prism height of 55 feet.

To find:

The total area to be painted.

Solution:

There are 4 external surfaces for the rectangular prism and 4 external surfaces for the triangular prism.

The rectangular prism has 4 rectangles out which there are 2 sets of similar rectangles.

There are two rectangles with lengths of 25 feet and widths of 10 feet while the other two rectangles have lengths of 55 feet and widths of 10 feet.

The area of a rectangle with a length of 25 feet and a width of 10 feet $= 25(10)= 250$ square ft.

The area of two such rectangles $= 2(250) = 500$ square feet.

The area of a rectangle with a length of 55 feet and a width of 10 feet $= 55(10)= 550$ square feet.

The area of two such rectangles $= 2(550) = 1100$ square feet.

The triangular prism has 2 triangles and 2 rectangles.

The triangles have base lengths of 25 feet and heights of 8 feet while the rectangles have lengths of 55 feet and heights of 14.8 feet.

The area of a triangle with a base length of 25 feet and a height of 8 feet $= \frac{1}{2}(25)(8)= 100$ square feet.

The area of two such triangles $=2(100)= 200$ square feet.

The area of a rectangle with a length of 55 feet and a width of 14.8 feet $= 55(14.8)= 814$ square feet.

The area of two such rectangles $= 2(814) = 1628$ square feet.

The total area to be painted $=500+1100+200+1628 = 3128$ square feet.

So an area of 3128 square feet is to be painted.

The surface area of a globe in Mr. Patton's classroom is about 152.39 square inches. Find its

Snezhnost [94]

Answer:

176.89in^3

Step-by-step explanation:

when finding the volume using the surface area, the best method that comes in my mind is finding the ratio between the surface area and volume which would be r/3 for a sphere. So if given that the surface area of the sphere is 152.39 square r/3=around 1.161, and when multiplied by 152.39 is around 176.89. another similar method is deriving the radius when given its surface area which is simply taking the square root of the surface area/4pi which turns out to be 3.482357088 or 3.48 which can then be plugged into the volume formula as the radius which is (3.48^3*4pi)/3 which turns out to be the same answer!
