Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds. What was his average speed

Answers

Answer 1

Answer:

His average speed was of 10.42 m/s

Step-by-step explanation:

We use the following relation to solve this question:

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity(in m/s), d is the distance(in meters), and t is the time, in seconds.

Usain Bolt of Jamaica set a world record in 2009 for the 200- meter dash with a time of 19.19 seconds.

This means that [tex]d = 200, t = 19.19[/tex]

So his average speed was of:

[tex]v = \frac{d}{t} = \frac{200}{19.19} = 10.42[/tex]

His average speed was of 10.42 m/s

What is a recession in an economy?

A recession is defined as a severe fall in economic activity that lasts more than a few episodes of time and is reflected in real GDP, income, employment, economic growth.

So if an economy is in a  recession and vehicle prices drop by eight percent.

Then, we have:

= $25,295 × 8%

[tex]\mathbf{= 25295 \times \dfrac{8}{100}}[/tex]

= $2023.6

The price of a car that was previously worth 25,295 will be:

= $25295 - $2023.6

= $23271

The area of the opening of a rectangular window is to be 120 square feet. If the length is to be 2 feet more than the width, what are the dimensions

Answers

Answer:

Width = 10ft

Length = 12ft

Step-by-step explanation:

For a rectangle of length L and width W, the area is calculated as:

A = L*W

In this case, we know that:

The area is 120 ft^2.

The length is 2 ft more than the width.

Then we can write:

L = W + 2ft.

If we use these two equations and replace them in the equation for the area of a rectangle, we get:

A = 120ft^2 = W*L = W*(W + 2ft)

120ft^2 = W*(W + 2ft)

Now we can solve this for W

120 ft^2 = W^2 + 2ft*W

Now we can rewrite this as:

W^2 + 2ft*W - 120ft^2 = 0

The solutions of this equation can be found by the Bhaskara's formula.

We know that for an equation of the form:

a*x^2 + b*x + c = 0

The two solutions are given by:

[tex]x = \frac{-b +\sqrt{b^2 - 4*a*c} }{2*a}[/tex]

in our case, we have:

a = 1

b = 2ft

c = -120ft^2

Then the solutions for the equation W^2 + 2ft*W - 120ft^2 = 0 are:

[tex]W = \frac{-2ft + -\sqrt{(2ft)^2 - 4*1*(-120ft^2)} }{2*1} = \frac{-2ft +- 22ft}{2}[/tex]

Then the two solutions are:

W = (-2ft - 22ft)/2 = -12ft  (this is a negative measure, does not have a real meaning in this case, so this solution can be discarded)

The other solution is:

W = (-2ft + 22ft)/2 = 10ft  (this is the correct solution)

Then the width is 10ft, and we know that the length is 2 ft longer than the width, then the length is:

L  = W + 2ft = 10ft + 2ft = 12ft

Determine which, if any, of the given values is a solution.

the perimeter of a rectangular field is 374 yards. if the width of the field is 88 yards, what is its length

Answers

Answer:

99 yards

Step-by-step explanation:

374 - 88 = 286

286 - 88 = 198

198/2 = 99

length = 99

The required length of the given rectangular field is 99 yards.

What is a rectangle?

A rectangle is a type of parallelogram having equal diagonals.

All the interior angles of a rectangle are equal to the right angle.

The diagonals of a rectangle do not bisect each other.

Given that,

the perimeter of rectangular field is 374 yards.

And its width is 88 yards.

Suppose the length is x yards.

Since the perimeter of a rectangle is given as P= 2(l + b), where l is the length and b is the width .

Substitute the respective values to get,

374 = 2(88 + x)

=> 2x = 374 - 176

=> 2x = 198

=> x = 99

Hence, the length of the rectangular field is given as 99 yards.
