What is the surface area of the rectangular prism shown by net?

Answers

The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.

Answer:

104

Step-by-step explanation:

all the angles of a triangle add up to 180, so set up an equation like this:

x+35+41=180

now solve for x

x=180-35-41

x=104

104 degrees a triangle = 180 degrees 104 + 41 + 35 = 180 degrees

Which equation gives the volume of the sphere? V = two-thirds (27 pi) V = four-thirds (27) V = two-thirds (27) V = four-third (27 pi)

Answers

Answer:

V = four-third (27 pi)

Step-by-step explanation:

Complete question;

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 27 pi feet cubed.

A sphere with height h and radius r. A cylinder with height h and radius r.

Which equation gives the volume of the sphere?

V = two-thirds (27 pi)

V = four-thirds (27)

V = two-thirds (27)

V = four-third (27 pi)

Volume of the cylinder V = πr²h

If Volume is 27pi feet cubed, hence;

27pi = πr²h

27 = r²h

Since r = h

27 = r³

r = ∛27

r = 3

Since the volume of the sphe4/3πr³re = 4/3πr³

Volume of sphere = 4/3π(27)

Volume of sphere = 4/3(27π)

Hence the correct option is V = four-third (27 pi)

B) Una empresa A gana S/ 42 758,35 en un ano. Si la empresa B gastara S/ 8774,55; tendria tantas ganancias como la primera empresa. Cual es la ganancia total de la empresa B?

Answers

Answer:

Las ganancias totales de la empresa B en dicho año fueron de $51.532,90.

Step-by-step explanation:

Dado que una empresa A gana $42.758,35 en un año, y si la empresa B gastara $8.774,55 tendría tantas ganancias como la primera empresa, para determinar cuál es la ganancia total de la empresa B se debe realizar el siguiente calculo:

Ganancias B - 8.774,55 = 42.758,35

Ganancias B = 42.758,35 + 8.774,55

Ganancias B = 51.532,90

Por lo tanto, las ganancias totales de la empresa B en dicho año fueron de $51.532,90.

Today's cafeteria specials at a high school in Westford are a deluxe turkey sandwich and a chef salad. During early lunch, the cafeteria sold 13 turkey sandwiches and 69 chef salads, for a total of $151. During the late lunch, 61 turkey sandwiches and 41 chef salads were sold, for a total of $143. How much does each item cost?

Answers

Answer:

chef salads = $2

turkey sandwiches = $1

Step-by-step explanation:

two equations can be derived from the question

13t + 69c = 151 eqn 1

61t + 41c = 143 eqn 2

t = turkey sandwiches

c = chef salads

multiply equation 1 by 61 and equation 2 by 13

793t + 4209c = 9211 eqn 3

793t + 533c = 1859 eqn 4

subtract equation 4 from 3

7352 = 3676c

c =2

substitute for c in equation 1

13t + 69(2) = 151

13t + 138 = 151

13t = 151 - 138

13t = 13

t = 1

vectors
p=(4,3) and q=(-2,7), find 4p -2q

Answers

Answer:

(20, -2)

Step-by-step explanation:

Given the coordinate vectors p=(4,3) and q=(-2,7),

4p - 2q = 4(4, 3)- 2(-2, 7)

4p - 2q = (16, 12) - (-4, 14)

4p - 2q = (16+4, 12-14)

4p - 2q =(20, -2)

hence the required vector is (20, -2)

A sports company wants to package a ball with a 1.5-inch radius in sets of two. They have two options: a cylinder or a square prism.The company wants to use the package that has the least amount of wasted space. The company should choose

Answers

Answer:

The Company should choose to get the cylinder packages ( V = 42.39 in³ )

Step-by-step explanation:

The volume of a cylinder of radius of circumference 1.5 in and h = 1.5*4

h = 6 in is:

V(c) = π *r²*h = π * (1.5)²*6 = π *2.25*6

V(c) = 42.39 in³

Now V(p) = Square of the base ( of side 3 in) * h

h = 6 in

V(p) = (3)²*6

V(p) = 54 in³

If we compare these two volumes we see that the volume of the cylinder is small than that of the square prism

for the circle shown it looks like the circle is centered at (1,3)

then h=1 and k=3 and the radius looks to be about 2

(x−1)^2+(y−3)^2=2^2
