Given that √5 = 2.24 and √50= 7.07 , find <br> √500 and √0.5

sineoko [7]

Answer:

see explanation

Step-by-step explanation:

using the rules of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

$\sqrt{\frac{a}{b} }$ ⇔ $\frac{\sqrt{a} }{\sqrt{b} }$

then

$\sqrt{500}$

= $\sqrt{100(5)}$

= $\sqrt{100}$ × $\sqrt{5}$

= 10 × 2.24

= 22.4

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

$\sqrt{0.5}$

= $\sqrt{\frac{50}{100} }$

= $\frac{\sqrt{50} }{\sqrt{100} }$

= $\frac{\sqrt{50} }{10}$

= $\frac{7.07}{10}$

= 0.707

Kate has 12 1/2 pounds of chocolate. She gives each of her 5 friends x pounds each and has 3 1/3 pounds left over. How much did

Alenkasestr [34]

Let's write an equation and solve for x
12 1/2 = 5x + 3 1/3
rewrite the mixed fractions as improper fractions and with denominator 6
75/6 = 5x + 20/6
subtract 20/6 from both sides
55/6 = 5x
divide both sides by 5 to isolate x
11/6 = x
That is 1 and 5/6 pounds per each of the friends

To check:
<span>12 1/2 =?= 5(1 5/6) + 3 1/3
12 1/2 =?= 55/6 + 3 1/3
12 1/2 =?= 25/2
12 1/2 = 12 1/2

Hope this helps</span>
