<u>For the first one:</u> ...√2*11, + 1. Use PEMDAS, then find the square root of the answer.

→ √2*11, + 1

→ 2 times 11 = 22, plus 1 = 23.

→ √23 = 4.79583152331.

→ Then round to the nearest 10th = 4.7<u>9</u>↑ = 4.8

<u>For the second one:</u> ... √4*8, + 1  + √2*8. Use PEMDAS, then find the square root to the answer.  

→ √4*8, + 1  + √2*8

→ √32 + 1 + √16

→ √33 + √16

→ 5.74456264654 + 4

→ 9.74456264654

→ If you need to round to the tenth, 9.7<u>4</u>↓ = 9.7

Galina-37 [17]

Answer:

Step-by-step explanation:

There is a missing operator in the second equation.

If the equation is 4x - 8y = 4, then the system is dependent. The second equation is a non-zero multiple of the first.

Solve the qn in attachment .​
galina1969 [7]

Answer:

\implies \dfrac{ -4x+7}{2(x-2) }

Step-by-step explanation:

The given expression to us is ,

\implies \dfrac{\frac{ 3}{x-1} -4 }{ 2 -\frac{2}{x-1}}

Now take the LCM as ( x - 1 ) and Simplify , we have ,

\implies \dfrac{\frac{ 3 -4(x-1) }{x-1} }{ \frac{2-2(2x-1)}{x-1}}

Simplifying further , we get ,

\implies \dfrac{ -4x+7}{2(x-2) }

<u>Hence the second option is correct.</u>

Some please help with this problem, I have tried multiple time but still couldn't get the right answer. :(
Tanzania [10]

Given data:

Total number of songs = 8

Rock songs = 3

Reggae songs = 2

Country songs = 3

Probability = Number of favorable outcomes / Total number of outcomes

To find:

When song is selected randomly to play first song and then second song from remaining ones ,

Probability when both the songs are from Reggae songs,

\begin{gathered} P\text{ =}\frac{2}{8}\times\frac{1}{7} \\ \text{   = }\frac{2}{56} \end{gathered}P=\frac{1}{28}

Thus , the probability is 1/28.

If one gallon is the same amount as 4 quarts, how many quarts are in 5 gallons?
wlad13 [49]
If one gallon = 4 quarts
Then 5 gallons = x quarts

To solve this we can set up a porportion

1/4 = 5/x

To solve the porportion we need to find the rule so how to we get to 4 from 1? Well we can multiply 1 by 4 to get one right?

So if this is true, 1 x 4 = 4 then 5 x 4 must equal x

5 x 4 = 20 so the answer would be 20 quarts are in 5 gallons

Another way to look at this is that you have 5 gallons and in each gallon is 4 quarts to if there is 4 quarts in every one gallon then that’s just 4 + 4 + 4 + 4 + 4 or 5 x 4

I hope this helps! <3
