We solve 6 + 4

6 + 4 = 10.

Square root of 10:

\boldsymbol { \sqrt{6 + 4} =  \sqrt{10}  }\\&#10;\\&#10;\\&#10;\boldsymbol {  \sqrt{10}l\underline{ \ 3.16227766017}}\\&#10;\boldsymbol {  \underline{- 10}l \ 3.16227766017 \times 3.16227766017 }\\&#10;\boldsymbol { \ \ \ 00}

<span>The square root of 10 is a periodic decimal (decimal that has infinite decimals, worth the redundancy)

 What is that periodic decimal?
</span>
\boxed{\textbf{3.16227766017} \boldsymbol{ \ \Leftarrow }\textbf{Square root of 10}}

Jerome burns 4 cal/min walking and 10 cal/min running. He walks between 10 and 20 min each day and runs between 30 and 45 min ea
erik [133]

Answer:

20 minutes should spend on walking and 30 minutes on running.

Step-by-step explanation:

Let x represents the minutes spent on walking and y represents the minutes spent on running,

∵ He burns 4 cal/min walking and 10 cal/min running,

So, the total calories burnt,

Z = 4x + 10y

Which has to be maximised.

Now, he walks between 10 and 20 min each day,

i.e. 10 < x < 20,

Also, he runs between 30 and 45 min each day,

i.e. 30 <  y < 45,

By graphing 10 < x < 20 and 30 <  y < 45,

We obtained the vertices of feasible region,

(10, 45), (20, 45), (10, 30) and (20, 30)

At (10, 45),

Z = 4(10) + 10(45) = 40 + 450 = 490,

At (20, 45),

Z = 4(20) + 10(45) = 80 + 450 = 530,

At (10, 30),

Z = 4(10) + 10(30) = 40 + 300 = 340,

At (20, 30)

Z = 4(20) + 10(30) = 80 + 300 = 380

Hence, maximum calories is 530 when 20 minutes spent on walking and 30 minutes spent on running.

-3/5 x 2/-9 x 8 write your answer in simplest form.
nata0808 [166]

Answer:

  16/15

Step-by-step explanation:

  \dfrac{-3}{5}\cdot\dfrac{2}{-9}\cdot 8=\dfrac{3\cdot 2\cdot 8}{5\cdot 9}=\dfrac{2\cdot 8}{5\cdot 3}=\dfrac{16}{15}

The two minus signs cancel, so the result is positive.
