Can some one solve this (squar roots)

Inessa05 [86]

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 $\sqrt{6}$

Choose the fraction that is greater than 3/18٫is less than 50/100٫and has 9 as its denominator

erik [133]

Answer:

4/9

Step-by-step explanation:

The denominator is the bottom value of a fraction, therefore we can discount 9/2

1/9 = 2/18. 2/18 is smaller than 3/18 so we can discount 1/9

50/100 = 0.5
5/9 = 0.55555...
0.55555... is greatest than 0.5, therefore we can discount 5/9

Answer is 4/9

Please please help. I have a bunch of these and I don’t understand it at all

The correct option is: Option (B) $\sum_{i=1}^{7} (5i-2)$

Explanation:

First thing is that the difference between each number in the series with the next number is 5. It means it must be the multiple of 5. There are two options that contain multiples of 5: Option B and Option D. Now in the option D, the upper limit is 6. If we put 6 in the expression: 5(6)-2, the last term would be 28. However in the series given in the question, the last term is 33. Hence 5(7) - 2 = 35 - 2 = 33 which is Option B.

When i=1: 5(1)-2 = 3
When i=2: 5(2)-2 = 8
When i=3: 5(3)-2 = 13
.
.
When i=7: 5(7)-2 = 35-2 = 33
Hence the correct option is (B).
