No, Mateo is not correct because he is older than his brother which would make 41 a greater value than b. The correct statement would be ‘b < 41’.

3 spheres of diameter 6cm,8cm and 10cm are melted to form a single sphere .find the diameter of the sphere.
julia-pushkina [17]

Answer:

Step-by-step explanation:

6/2=3 cm is the radius V(4/3πr³) = 4/3.π.27…(1)

8/2= 4 cm is the radius and V = 4/3.π.64…..(2)

10/2=5 cm is the radius and V = 4/3.π.125…(3)

The Total Volume is the addition of (1)+(2)+(3) or 4/3π (27+64+125) or New volume is 4/3.π.(216) cm³ and therefore...

The radius of the New Solid Sphere is Cube Root of 216 (r³) = √6.6.6 or r = 6 cm and the diameter is 6.2 = 12 cms.

12 cms answer. Brainlist please?

Brian spends 3 5 of his wages on rent and 1 3 on food. If he makes £735 per week, how much money does he have left?
Margarita [4]

Answer :

Brian has $49 left.

Step by step explanation :

Step 1 : Find how much money Brian spends on rent and food.

First question we should be asking is what is 3/5 of 735?

Let's find that.

\frac{3}{5} * \frac{735}{1}

= \frac{(3)(735)}{(5)(1)}

= \frac{2205}{5}

= 441

We know Brian spends $441 on rent. Now we find how much he spends on food.

\frac{1}{3} * \frac{735}{1}

= \frac{(1)(735)}{(3)(1)}

= \frac{735}{3}

= 245

Brian spends $245 on food.

Step 2 : Add what he spends on rent and food together.

$441 + $245 = $686

Step 3 : To find out how much money Brian has left, we subtract $686 from $735.

$735 - $686 = $49

Conclusion : Brian has $49 left.

Hope this helps, please mark brainliest if possible. Have a nice day.

Answer:

The first one is:

\left[\begin{array}{ccc}0&7&2\\5&3&1\\4&-1&6\end{array}\right]

The second one is:

\left[\begin{array}{ccc}1&2&6\\8&3&-2\\0&4&5\end{array}\right]

The third one is:

\left[\begin{array}{ccc}3&-2&5\\4&2&0\\-1&6&1\end{array}\right]

Step by Step:

<em>First one:</em>

<em>7+0+2=9</em>

<em>6+1+2=9</em>

<em>6+-1+4=9</em>

<em>4+5+0=9</em>

<em>6+3+0=9</em>

<em>Second one:</em>

<em>6+2+1=9</em>

<em>6+-2+5=9</em>

<em>4+5+0=9</em>

<em>0+8+1=9</em>

<em>1+3+5=9</em>

<em>Third one:</em>

<em>3+-2+5=6</em>

<em>4+2+0=6</em>

<em>-1+6+1=6</em>

<em>5+0+1=6</em>

<em>3+4+-1=6</em>

<em>3+2+1=6</em>
