Answer:

Pretty sure a loss of -27.08%, check the formula for loss percent

Step-by-step explanation:

Assuming this means 120 for 20 oranges.

so for 200, every 20 was bought for 120.

There are 10 20s in 200 so that's 10 score, which means 120*10 = 1200

So 1200 was spent.

25 were rotten which means they now have 175

selling for 5 each means 5*175 = 875 was the profit.

Since they spent 1200 and made 875 there was a loss.  

Then I think percent loss/ gain is (revenue - cost)/cost where revenue is what was made and cost is what was spent.  so this makes (875-1200)/1200 = -.2708 = -27.08%

Kinda rusty on this so double check what loss percent is.

If AC = 20 centimeters, and BC = 16 centimeters, which does AB equal?
Anna11 [10]

Answer:

The answer is B. 12 cm

Step-by-step explanation:

ABC is a right triangle

AB and BC are the legs and AC is the hypotenuse.

The Pythagorean theorem a^2 + b^2 = c^2 can be manipulated to solve for a and get 12.

Imaginá que tenés 125 dados cúbicos del mismo tamaño ¿Cuantos dados de altura tiene el cubo de mayor tamaño que podés armar apil
kumpel [21]

Answer:

(i) Debemos apilar 5 dados para construir el cubo de mayor tamaño.

(ii) Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.

Step-by-step explanation:

(i) Sabemos por la Geometría Euclídea del Espacio que un cubo es un sólido regular con 6 caras cuadradas y longitudes iguales. Cada dado tiene un volumen de 1 dado cúbico y 125 dados dan un volumen total de 125 dados cúbicos.

El volumen de un cubo está dado por la siguiente fórmula:

V = L^{3}

Donde:

L - Longitud de la arista, medida en dados.

V - Volumen del cubo, medido en dados cúbicos.

Ahora, necesitamos despejar la longitud de la arista para calcular la altura máxima posible:

L = \sqrt[3]{V}

Dado que V = 125\,dados^{3}, encontramos que la altura del cubo de mayor tamaño sería:

L =\sqrt[3]{125\,dados^{3}}

L = 5\,dados

Debemos apilar 5 dados para construir el cubo de mayor tamaño.

(ii) El área cuadrada formada por cubos está determinada por la siguiente fórmula:

A = L^{2}

Donde:

L - Longitud de arista, medida en dados.

A - Área, medida en dados cuadrados.

Puesto que la longitud de arista se basa en un conjunto discreto, esto es, el número de dados disponibles, debemos encontrar el valor máximo de L tal que no supere 125 y de un área entera. Es decir:

L \leq 125\,dados

Si cada cubo tiene un área de 1 dado cuadrado, entonces un cuadrado conformado por 125 dados tiene un área total de 125 dados cuadrados. Entonces:

L^{2}< 125\,dados^{2}

Esto nos lleva a decir que:

L < 11.180\,dados

Entonces, la longitud máxima del cuadrado con la mayor cantidad de cubos posible es de 11 dados. El número total requerido de cubos es el cuadrado de esa cifra, es decir:

n = (11\,dados)^{2}

n = 121\,dados

Se necesita 121 dados cuadrados para formar el cuadrado con la mayor cantidad de dados posibles, quedando 4 dados sobrantes.

samanthas house is 72 feet wife. in a photograph the width of the house was 4 inches, and its height was 2.5 inches. what is the
Anna11 [10]
So to find the ratio of the actual house to the house in the picture you would divide 72/4 to get 18. this means that the ratio is 18:1. Now multiply 2.5 x18 to get the real life height of the house. 2.5x18=45.
So the house is 45 feet tall.
Please anyone correct me if I'm wrong but I think this is right.
