Answer:

The average speed of usain bolt in meter per second is 10\frac{5}{12}.

Step-by-step explanation:

It is given that usain bolt set the world record for sprinting 100 m in approximately 9 3/5 a second.

Formula for average speed.

speed=\frac{distance}{time}

Given distance is 100 m and time in sec is

9\frac{3}{5}=\frac{45+3}{5}=\frac{48}{5}

The average speed in meter per second is

speed=\frac{100}{\frac{48}{5}}

speed=\frac{500}{48}

speed=\frac{125}{12}

speed=10\frac{5}{12}

Therefore the average speed of usain bolt in meter per second is 10\frac{5}{12}.

densk [106]

Answer:

<u>The additional 1.3% of increase in the annual interest rate that Jack is receiving in his savings account, from 2.8% to 4.1%, represent an increase of 46.42%.</u>

Step-by-step explanation:

Jacks's savings account annual interest rate before = 2.8%

Jacks's savings account annual interest rate after the increase = 4.1%

Difference of the two rates = 4.1% - 2.8% = 1.3%

How much percentage is that additional 1.3% from the rate before the increase?

(1.3 * 100)/ 2.8 = 130/2.8 = 46.42%

<u>The annual interest rate increased by 46.42% from the previous annual interest rate.</u>

Hi, your question was incomplete hence I have attached the complete version of the question below.

Answer:

<u>5x^3 y^2</u>

Step-by-step explanation:

Using the property of the product of the exponents on the base and removing the parentheses,

(125x^9y^6)^(1/3) = (125)^(1/3) * (x^9)^(1/3) * (y^6)^(1/3)

= (125)^(1/3) * (x)^9*(1/3) * (y)^6*(1/3)

= 5 * (x)^3 * (y)^2                                                    

= 5 x^3 y^2

hence the required result is 5 x^3 y^2
