We will use this formula = 1/2 × base × height
And thus
1/2 × 8 ×8

Answer:
<u>Usain Bolt's average speed in yards per second was 11.4</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
World record of Usain Bolt = 9.589 seconds
Distance of the world record = 100 meters
1 yard = 0.9144 meters ⇒ 100 meters = 109.36 yards
2. What was Usain Bolt's average speed in yards per second?
Let's recall that the formula of speed is:
Speed = Distance/Time
Replacing with the values we know:
Usain Bolt's Speed = 109.36/9.589
<u>Usain Bolt's Speed = 11.4 yards per second (Rounding to one decimal place)</u>
Let x be the amount each friend pays
.
There are five friends contributing ,so
5x will be the total money collected
.
It needs to equal the price plus the tax, 210 + 15
= 225
So the equation becomes,
5x = 225
dividing right side by 5, we have
x = 225/5 = 45
Answer: So each frien pays $45.
So there’s no actual question because you didn’t attach anything
