A square is cut diagonally into two equal parts. If each part has an area of 50 cm^2, then what is the perimeter of each part?
AysviL [449]

Answer:

<u><em>30cm</em></u>

Step-by-step explanation:

Given data

When are square is cut diagonally into two parts

The resulting shape is a triangle

hence the area of the square = 50+50 = 100cm^2

The length of each side of the square = √100= 10cm

likewise the diagonal of the square = 10cm

<u><em>Hence the perimeter of the resulting triangle= 10+10+10= 30cm</em></u>

Se dispone de 800 000 para invertir. Una cuenta paga el 18% de interés anual, y otra paga el 21%. ¿Cuánto debe invertirse en cad
Genrish500 [490]

Se debe depositar $ 600 000 en la cuenta con 18 % de interés <em>anual</em> y $ 200 000 en la cuenta con 21 % de interés <em>anual</em> para recibir $ 150 000 en intereses.

<h3>¿Cuánto se debe invertir en cada cuenta para alcanzar las ganancias deseadas en un período dado?</h3>

En este problema tenemos un depósito repartido en dos cuentas, que adquiere ganancias de manera <em>continua</em> en el tiempo. En consecuencia, tenemos por interés compuesto la siguiente ecuación a resolver:

x · (18/100) + (800 000 - x) · (21/100) = 150 000

168 000 - (3/100) · x = 150 000

(3/100) · x = 18 000

x = 600 000

Se debe depositar $ 600 000 en la cuenta con 18 % de interés <em>anual</em> y $ 200 000 en la cuenta con 21 % de interés <em>anual</em> para recibir $ 150 000 en intereses.

Mamie saved $161.25. This is 25% of the amount she needs to save, how much money does Mamie need to save?
babunello [35]
You would solve this by writing it as a porpotion. It would be 25/100=161.25/x. Then, you would multiply the 100 and 161.25, which would get you 16125, then you would divide this by 25, which would get you your answer : $645.
