The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Step-by-step explanation:

We have to calculate his unit rate for both type of races

So,

<u>Unit rate for 400m race:</u>

Distance = 400m

Time = 43 sec

$Unit\ rate = U_1= \frac{Distance}{Time}\\=\frac{400}{43}\\=9.30\ meters\ per\ second$

<u>Unit rate for 300m Race:</u>

Distance = 300m

Time = 31 sec

$Unit\ Rate= U_2=\frac{300}{31}\\=9.68\ meters\ per\ second$

The difference between both unit rates is:

$U_2-U_1 = 9.68-9.30\\=0.38 => 0.4\ meters\ per\ sec$

Hence,

The difference between both unit rates rounded off to the nearest tenth is: 0.4 meters per second

Can someone show me the steps to solve this

Answer:

$87 - 18 \sqrt{6}$

Step-by-step explanation:

We want to expand:

$( \sqrt{6} - 9)^{2}$

We expand to get:

$( \sqrt{6} - 9)( \sqrt{6} - 9)$

$\sqrt{6} ( \sqrt{6} - 9) - 9( \sqrt{6} - 9)$

We expand using the distributive property to get:

$6 - 9 \sqrt{6} - 9 \sqrt{6} + 81$

$6 - 18 \sqrt{6} + 81$

Finally simplify to get:

$87- 18 \sqrt{6}$
