The total surface area of a cube is 294cm^2.

Work out the volume of the cube.​

Answers

Answer 1

Answer:

343 cm ^3

Step-by-step explanation:

A cube has 6 squares of equal sizes. 294/6 = 49

The area of one square is 49

Since the area is the length squared, the square root of 49 is 7.

Volume of a cube is area times height. 49 x 7 = 343 cm^3

Do parallel lines that are not vertical have the same slope?


Yes or no

Answers

Answer:

Yes

Step-by-step explanation:

If the lines were vertical, the slope would be undefined (you can't divide by 0).

If the lines were otherwise, the lines have the same slope if they are parallel.

Answers

Answer:

No, both of the numbers are less than one whole and when you multiply them (I got 4/5) 4/5 is less than both of the factors.

Step-by-step explanation:

Y'all what's the answer?

Answers

Parallel = has same slope
On points( 3,4) (-2,2)
(2-4)/(-2-3) = -2/-5 = 2/5 slope

Use same formula: (y2-y1)/(x2-x1)

Find the slope of the other points:
(-2,-5) and (-7,-3)
(-3-(-5))/(-7-(-2)) = 2/-5 = -2/5

(-1, 1) and (-6, -1)
(-1-1)/(-6-(-1)) = -2/-5 = 2/5

(0,0) and (2,5)
(5-0)/(2-0) = 5/2

(1,0) and (6,2)
(2-0)/(6-1) = 2/5

(3,0) and (8,2)
(2-0)/(8-3) = 2/5

Which has same slope of 2/5?

- 2x + 5 = 4
Need help solving

Answers

Answer:

x = 1/2 or 0.5

Step-by-step explanation:

-2x + 5 = 4

-2x = 4 -5

-2x = -1

-1(-2x = -1)

2x = 1

x = 1/2 or 0.5

-2x + 5 = 4 | minus 5 from both sides
-2x =4 -5
-2x = -1 | divide both sides by -2
x= 1/2

Las abejas tienen que hacer 50.000 salidas para obtener 1 quilogramo de miel. ¿Cuántas salidas tendrá que hacer para obtener 5 quilogramos de miel?

Answers

Answer:

Tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.

Step-by-step explanation:

Con la información proporcionada, puedes usar una regla de tres para calcular cuántas salidas tendrá que hacer para obtener 5 kilogramos de miel dado que las abejas tienen que hacer 50.000 salidas para obtener 1 kilogramo de miel:

1 kilogramo    →   50.000 salidas

5 kilogramos  →               x

x=(5*50.000)/1

x=250.000

De acuerdo a esto, la respuesta es que tendrá que hacer 250.000 salidas para obtener 5 kilogramos de miel.

Mrs. Simpson is frosting circular sugar cookies. Each cookie is 7 cm in diameter. How many square inches will she need to frost one dozen cookies?

Answers

Answer:

51.92 square inches

Step-by-step explanation:

Area of a circle = (pi)(r^2)

if the diameter is 7, the radius is 3.5

A = 3.14 x 3.5

A = 10.99 cm^2 for one cookie

10.99 x 12 for a dozen = 131.88 cm^2

converting cm to inches, you divide by 2.54

131.88/2.54 = 51.92 square inches.

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answers

Question:

A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Which expression represents the area in square feet that the homeowner will cover with fertilizer?

Answer:

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]

Step-by-step explanation:

Given

[tex]Length = 4w^2 + 3w - 1[/tex]

[tex]Width = 5w - 2.[/tex]

Required

Determine an expression for the area

Area is calculated as:

[tex]Area = Length *Width[/tex]

[tex]Area = (4w^2 + 3w - 1) * (5w - 2)[/tex]

Expand

[tex]Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2[/tex]

Collect like terms

[tex]Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2[/tex]

[tex]Area = 20w^3 + 7w^2 - 11w + 2[/tex]
