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.

Micheal is collecting sea glass from the beach. He begins with 14 pieces in his collection and adds 2 new pieces each day. Determine how may days it will Micheal to have 80 pieces of sea glass in his collection.

Answers

Answer:

It would take Micheal 22 days.

Step-by-step explanation:

The end goal is to have 80 and we begin with 14

So, 80 - 14 = 66 pieces left to collect

If he collects 3 per day we'll divide 66 by 3, which equals 22

Therefore it takes him 22 days

simple interest = £40

rate = ?

simple interest = PTR / 100

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.

Therefore, the two equations given represents a proportional relationship.

∠SVU = 49°

Step-by-step explanation:

∠SVU is an inscribed angle and arc SU is the arc it intercepts

If you didn't know an inscribed angle is equal to half the measure of its intercepted arc.

Hence ∠SVU = arc SU / 2

if arc SU = 98

Then ∠SVU = 98/2 = 49

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

Now, it will look like this:

A)mean is 1.38  mode is 1.5  median is 1.4

B)mean is 1.775  mode is 1.2  median is 1.75

the mean is the average of the numbers added together divided by how many numbers are listed. 1.5+1.2+1.3+1.5+1.4=6.9  6.9 divided by 5 = 1.38

mode is the number that shows up in the list the most.
