Answer:

2\sqrt{6}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplifying the radicals

\sqrt{96}

= \sqrt{16(6)}

= \sqrt{16} × \sqrt{6} = 4\sqrt{6}

\sqrt{24}

= \sqrt{4(6)}

= \sqrt{4} × \sqrt{6} = 2\sqrt{6}

Thus

\sqrt{96} + 2\sqrt{6} - 2\sqrt{24}

= 4\sqrt{6} + 2\sqrt{6} - 4\sqrt{6} ← collect like terms

= 2\sqrt{6}

Answer:

<h2>2 \sqrt{6}</h2>

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>
  • simplifying redical
  • PEMDAS

first thing

in your question about 70% is done so need to simplify it a little

\sqrt{96}  + 2 \sqrt{6}  -  2\sqrt{24}

\sqrt{ {4}^{2} \times 6 }  +  2\sqrt{6}  - 2 \sqrt{2 ^{2} \times 6 }

4 \sqrt{6}  + 2 \sqrt{6}  - 4 \sqrt{6}

<h2>2 \sqrt{6}</h2>

A recipe calls for mixed nuts with 50% peanuts. 1/2 pound of 15% peanuts has already been used. How many pounds of 75% peanuts n
Galina-37 [17]
Now you have
<u />
<u>(.15)0.5 lb peanuts</u>     =     <u>0.075 lb peanuts</u>
0.5 lb  nuts                              0.5 lb nuts

for every pound of 75% mixed nuts you add, you get .75 lb peanuts, how many pounds, x, do you need to add to get the ratio 50 to 100?

<u>0.075 lb peanuts + 0.75x lb peanuts</u><em>       =    <u /></em><u>   50   </u><u>
</u>0.5 lb nuts + x lb nuts                                      100

cross multiply

(0.075 + .75x) 100 = (0.5 + x) 50
7.5 + 75x = 25 + 50x
25x = 17.5
x = 0.7 lb of 75% peanuts

Can someone please answer and explain thank you! I’ll mark brainliest
k0ka [10]

Answer:

Step-by-step explanation:

You first multiply the a with bx and c then after the answer when you multiply you "add" with it would be something like

ex: 6x+4=28

         - 4  -4     subtract both sides

------------------------

        6x=24      then divide 6 with 24.

         x= 3

Paula salió de su casa rumbo al trabajo avanzo 8km al este y 13km al norte. Si hubiera un camino recto desde su casa a su trabaj
zhannawk [14.2K]

Answer:

15.26km

Step-by-step explanation:

Con la informacion de la pregunta e hecho un diagrama de la situacion. Podemos ver en el diagrama que el recorido forma un triángulo rectángulo. Entonces para saber la distancia que recorreria por el camino recto desde su casa a su trabajo tendriamos que calcular el valor de x, que se puede calcular usando el teorema de pitagoras que es el siguiente.

a^{2} + b^{2} = c^{2}

donde a y b son el ancho y el alto del triangulo y el c seria x

8^{2} + 13^{2}  = x^{2}

64 + 169 = x^{2}

233 = x^{2}

15.26 = x

Finalmente, podemos ver que la distancia seria 15.26km
