Why do whole numbers with an exponent get bigger while fractions with an exponent get smaller.

1 answer:

8 0

Raising a whole number to a power means:

   Take (a number of things) a number of times, and then possibly
   take that big number of things a number of times again.

Raising a fraction to an exponent means:

   Take a piece of (a piece of one thing), and then possibly
      take just a piece of that smaller piece.

Tatiana [17]

Answer:

35%

Step-by-step explanation:

40% + 25% = 65% minus that bye 100 you would get 35% the reason the answer isn't 65 is because add 40+25+65=130 which a whole is equal to 100 but if you do 40+25+35= 100 so thr answer is 35% :)

Answer:

Luciana y Marta recorren 4,351 kilómetros y 2,801 kilómetros, respectivamente.

Step-by-step explanation:

El enunciado tiene un error tipográfico que induce a equivocación. El enunciado correcto es el siguiente: <em>Tres corredoras salieron a entrenar Amalia recorrió 4,121 kilómetros; Luciana 1,55 kilómetros más que Marta y esta 1 8/25 kilómetros menos que Amalia. ¿Cuántos kilómetros recorrió Luciana y Marta? </em>

Sean $x,y,z$ las distancias recorridas por Amalia, Marta y Luciana, en kilómetros. A partir de la descripción del enunciado tenemos el siguiente sistema de ecuaciones lineales:

Amalia

$x = 4,121\,km$ (1)

Marta

$y = x-1.32\,km$ (2)

Luciana

$z = y + 1.55\,km$ (3)

La solución del sistema de ecuaciones lineales es:

$x =4,121\,km, y = 2,801\,km, z = 4,351\,km$

Luciana y Marta recorren 4,351 kilómetros y 2,801 kilómetros, respectivamente.

Can someone help me solve for x in this equation?? 25+3.50x < 17+7.50x

Lelu [443]

So we want to solve like if it was just a basic equation. We start with 25+3.50x<17+7.50x and get rid of our smallest x. That means we get rid of the 3.50x by subtracting from both sides and our new equation is 25<17+4x. Let’s get our x by itself shall we, so let’s subtract 17 from both sides and we get 8<4x. Finally all we do is divide by 4 and just like that 2
