SOMEONE PLEASE HELP!! I've tried this question twice and I just can't seem to get it

jolli1 [7]

$\underline{\underline{\large\bf{Given:-}}}$

$\red{\leadsto}\:$ $\textsf{Total Number of fish }$ $\sf = 30$

$\red{\leadsto}\:$ $\textsf{ Number of carp fish }$ $\sf = 9$

$\underline{\underline{\large\bf{To Find:-}}}$

$\orange{\leadsto}\:$ $\textsf{ Ratio of carp to sticklebacks to tench }$ $\sf in \:the \:pond$

$\\$

$\underline{\underline{\large\bf{Solution:-}}}\\$

$\longrightarrow$ Number of fish that are not carp = Total fish - number of carp fish

$\begin{gathered}\implies\quad \sf 30-9 \\\end{gathered}$

$\begin{gathered}\implies\quad \sf 21 \\\end{gathered}$

$\longrightarrow$ Since 1/3 of remaining fish which are not carp are sticklebacks , Number of sticklebacks =

$\begin{gathered}\implies\quad \sf \frac{1}{3} \times number \:of \:remaining \: fish\\\end{gathered}$

$\begin{gathered}\implies\quad \sf \frac{1}{3}\times 21 \\\end{gathered}$

$\begin{gathered}\implies\quad \sf 7 \\\end{gathered}$

<u>Now</u> ,

$\longrightarrow$ Number of tench = Total number of fish - (Number of carp + Number of sticklebacks)

$\begin{gathered}\implies\quad \sf 30-(9+7) \\\end{gathered}$

$\begin{gathered}\implies\quad \sf 30-16\\\end{gathered}$

$\begin{gathered}\implies\quad \sf 14\\\end{gathered}$

$\therefore$ Ratio of carp to sticklebacks to tench in the pond =

$\begin{gathered}\quad\quad \boxed{\sf {9: 7:14}} \\\end{gathered}$

Which expression is equivalent to 10√5

mixer [17]

Answer:

A. √500

Step-by-step explanation:

Since 500 = 5·100 = 5·10² you can move the 10² out of the √ as 10.

Hence 10√5 = √500

So we're using these rules:

√a·b = √a·√b

and of course

√a² = a (a>0)

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.

Yanka [14]

Answer:

The sum is $t$ .

Step-by-step explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

$10t+(t-10t)$

Remove the parenthesis.

$10t+t-10t$

Simplify the number

$10t-10t+t$

Use Additive inverse.

$t$

Hence, the sum is $t$ .

Michael is 17 years older than John. In 4 years, the sum of there ages will be 49. Find Michaels present age.

Crank

Answer:

29

Explanation:

Let John be x years old.

Michael is <span>x+17</span> years old.

In four years time, the sum of their ages will be 49:

<span>x+x+17+2<span>(4)</span>=49</span>

<span>2x=24</span>

<span>x=12</span>

So Michael is <span>12+17=29</span> years old now.
