Answer: x= 385/12

Step-by-step explanation:

You would first change the denominator to some number that is common. Then combine the like terms. Lastly, subtract the fraction from the equal and you get your x.

\frac{13}{4} +\frac{1}{6} +x=\frac{71}{2} \\(\frac{39}{12})+(\frac{2}{12})+x=\frac{426}{12} \\\frac{41}{12}+x=\frac{426}{12}  \\x=\frac{385}{12}

A swimming pool is 15 by 30 feet and a consistent 5 feet deep. you are painting the walls and floor of the pool. if a gallon can
lukranit [14]

the bottom of the pool is 15 x 30 = 450 sq feet.

 you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet

 then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet

 for a total of 450 +300 +150 = 900 square feet

 1 can covers 250 sq ft

so 900/250 = 3.6

 so you would need 4 cans of paint

A prism is created using 2 regular pentagons as bases. The apothem of each pentagon is 2.8 centimeters. Which expression represe
mash [69]
Recall that the volume of a regular prism is given by the area of the base times the height.

Given that the base of the prism is a regular pentagon with an apothem of 2.8 centimeters.
The pentagon consist of 5 isosceles triangles with the apothem as the height and the side of the pentagon as the base.

Recall that the are of a triangle is given by 1/2 base times height.

Thus the area of of the pentagon base of the prism is given by
Area= \frac{5}{2} x\times2.8=7x

Therefore, the volume of the prism is given by
Volume=7x(2x+1)=14x^2+7x

What is the area of this composite shape?<br> Enter your answer in the box.
bonufazy [111]

Answer:

The answer to your question is:  53 in²

Step-by-step explanation:

Area = ?

Process: divide the shape in one rectangle and one triangle.

Area of rectangle

                            A = base x height

                            A = 8 x 6

                            A = 48 in²

Area of rectangle

                          base = 13 - 8

                                   = 5 in

                          height = 6 - 4

                                     = 2 in

                          Area = (b x h) / 2

                                   = (5 x 2) / 2

                                   = 10 / 2

                                   = 5 in²

Total area = 48 + 5 = 53 in²
