Find the area of each face and add them all up together:
Area of triangular base- 1/2 • 6 • 5.2 = 15.6 in2
Area of 1 triangle side face:1/2 • 8 • 6 = 24 in2
Multiply 24 by 3 (bcos there are 3 triangular lateral faces) 24 • 3= 72

Add area of base and arae of all lateral faces:
72 + 15.6 = 87.6

John is twice as old as Mary. The sum of thelr ages is 21. How old Is Mary?

Answers

Answer:   7 years

Step-by-step explanation:

let x be the age of Mary

so John's age will be 2x

the equation becomes

2x+x=21

3x=21

x=21/3

x=7

Answer:

Step-by-step explanation:

Let Mary's age = x years

John's age = 2 * x = 2x

The sum of their ages = 21

x + 2x = 21

3x = 21

Divide both sides by 3

x = 21/3

x = 7

Mary's age = 7 years

Answer:

44 degrees

Step-by-step explanation:

The angles x + 2 and x are complementary; they sum up to 90 degrees.

Thus, x + 2 + x = 90 degrees, or:

2x = 88, or

x = 44.

The value of x is 44 degrees.

ethan invests £500 in the bank for 2 years he earned £40 simple interest

Answers

Answer:

Rate = 4%

Step-by-step explanation:

principal = £500

time = 2 years

simple interest = £40

rate = ?

simple interest = PTR / 100

£40 = £500*2*R /100

£40*100 = £1000*R

£4000/£1000 = R

Me fui a Cacao Show a comprar bombones blancos y bombones de chocolate negro: Si compro,2 bombones de chocolate negro y 5 de chocolate blanco esa suma nos da $40. Si compro 4 bombones de chocolate negro y 2 de chocolate blanco gasto $26. ¿Cuánto cuesta cada Bombón negro? Y los de chocolate blanco, cúanto cuesta la unidad?

Answers

Answer:

Cada bombón negro cuesta $3,125 y cada bombón blanco cuesta $6,75

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.

Resolver un sistema de ecuaciones consiste en buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones. Es decir, resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

Si compro 2 bombones de chocolate negro y 5 de chocolate blanco, la suma da $40. Si compro 4 bombones de chocolate negro y 2 de chocolate blanco, gasto $26. Siendo:

x: precio de cada bombón de chocolate negroy: precio de cada bombón de chocolate blanco

Entonces el sistema de ecuaciones a resolver es:

[tex]\left \{ {{2*x+5*y=40} \atop {4*x+2*y=26}} \right.[/tex]

El método de sustitución consiste en aislar en una ecuación una de las dos incógnitas para sustituirla en la otra ecuación.

Entonces, aislando la variable x de la primer ecuación:

[tex]x=\frac{40-5*y}{2}[/tex]

Sustituyendo en la segunda ecuación:

[tex]4*\frac{40-5*y}{2}+2*y=26[/tex]

Resolviendo:

[tex]\frac{4}{2}* (40-5*y)+2*y=26[/tex]

2* (40-5*y)+2*y=26

2*40- 2*5*y+2*y=26

80- 10*y+2*y=26

- 10*y+2*y=26 -80

-8*y= -54

y= (-54)÷ (-8)

y= 6,75

Reemplazando en la expresión [tex]x=\frac{40-5*y}{2}[/tex], se obtiene:

[tex]x=\frac{40-5*6,75}{2}[/tex]

[tex]x=\frac{40-33,75}{2}[/tex]

[tex]x=\frac{6,25}{2}[/tex]

x= 3,125

Entonces, cada bombón negro cuesta $3,125 y cada bombón blanco cuesta $6,75

Step 1: 6x + 1 = 1; Step 2: 6x = 0
Step 1: 8x - 12 = 1; Step 2: 8x = 13
Step 1: 8x - 3 = 1; Step 2: 8x = 4

Answers

Answer:

Step-by-step explanation:

Given equation:

4(2x - 3) = 1

Step 1: open the parenthesis

4(2x - 3) = 1

8x - 12 = 1

Step 2: collect like terms

8x - 12 = 1

8x = 1 + 12

8x = 13

step 3: divide both sides by the coefficient of x

8x = 13

x = 13/8

The correct steps to solve the equation:

Step 1: 8x - 12 = 1; Step 2: 8x = 13

The area and the perimeter of the picture are:

Area = 160 cm^2Perimeter = 67.31 cm

Step-by-step explanation:

To find the area of that figure, you can find the area how if it was a rectangle and next subtract the area of the triangle in the upper part. The area of a rectangle could be found by the next formula:

Area of a rectangle = base * height

As you can see in the picture, the base is 16 cm and the height is 12 cm, then we replace in the formula:

Area of a rectangle = 16 cm * 12 cmArea of a rectangle = 192 cm^2

Now, we calculate the area of the triangle to subtract to the area we found and obtain the real area, the formula to obtain the area of a triangle is:

Area of a triangle = (base * height) / 2

The height of the triangle is 8 cm, and the base is 8 cm too, because you subtract to the base of the rectangle (16 cm) the measurements in the upper part (16 - 4 - 4 = 8), Now, we replace in the formula:

Area of a triangle = (8 cm * 8 cm) / 2Area of a triangle = (64 cm^2) / 2Area of a triangle = 32 cm^2

We subtract to the found area:

Area of the picture = 192 cm^2 - 32 cm^2Area of the picture = 160 cm^2

To find the perimeter, you must add all the sides of the picture, but, as you can see, there is a side that doesn't have the measurent, this is the hypotenuse of the triangle used before, but how we know the other sides, we can use Pythagorean theorem:

[tex]a^{2}+b^{2}=c^{2}[/tex]

Where:

a = Opposite leg (8 cm)b = Adjacent leg (8 cm)

So, we replace in the theorem:

[tex]a^{2}+b^{2}=c^{2}[/tex][tex](8 cm)^{2}+(8cm)^{2}=c^{2}[/tex] (and we clear c)[tex]\sqrt{(8 cm)^{2}+(8cm)^{2}} =c[/tex] [tex]\sqrt{64 cm^{2}+64cm^{2}} =c[/tex] [tex]\sqrt{128cm^{2}} =c[/tex]c = 11.3137085 cmc ≅ 11.31 cm

At last, we add all the sides of the picture begining by the base and going by the left side:

Perimeter of the picture = 16 cm + 12 cm + 4 cm + 11.31 cm + 8 cm + 4 cm + 12 cmPerimeter of the picture = 67.31 cm approximately.

A planet has a circular orbit around a star. It is a distance of 98,000,000 km from the centre of the star. It orbits at an average speed of 45,000 km/h. How many Earth days does it take the planet to orbit the star? Give your answer to 2 sf.

Answers

Answer:

91 days

Step-by-step explanation:

Given that,

A planet is at a distance of 98,000,000 km from the centre of the star.

It orbits at an average speed of 45,000 km/h.

The speed of an object is given by the distance covered divided by the time taken. So,

[tex]v=\dfrac{d}{t}\\\\t=\dfrac{d}{v}\\\\t=\dfrac{98,000,000}{45,000}\\\\t= $$2177.77\ h[/tex]

or

t = 90.74 days ≅ 91 days

So, the planet take 91 days to orbit the star.

Which graph or equation represents a Nonpoportional relationship A B C or D

Answers

Answer:

A

Step-by-step explanation:

A graph that represents a proportional relationship usually has the line cutting through the line of origin (0, 0).

The graph in option A does not have the line passing through the point of origin (0, 0), therefore, it does not represent a proportional relationship.

For an equation that represents a proportional relationship, it is written in the form of y = kx

Where, k is the constant of proportionality.
