A sprinter finished a 100-meter race in a time of 12.63 seconds.
If the sprinter were able to keep the same rate of speed, how long
would it take him to complete the 10,000-meter race?

Answers

Answer 1

Answer:

1263 seconds

Step-by-step explanation:

100 meters = 12.63 seconds

multiply both sides by 100 since

100*100= 10,000 meters

12.63*100= 1263 seconds

A man covers a distance of 150m in 1.5mins. Find the average speed in km per hour

Answers

Answer:

6 Km / hour

Step-by-step explanation:

Convert distance to Km ( 1 Km = 1000 m )

150 m = 150 ÷ 1000 = 0.15 Km

Convert 1.5 mins to hours ( 1 hour = 60 minutes )

1.5 = 1.5 ÷ 60 = 0.025 hours

average speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{0.15}{0.025}[/tex] = 6 Km / hour

The average speed in km per hour is 6 kilometers per hour

How to determine the average speed?

The given parameters are:

Distance = 150 mTime = 1.5 mins

Convert meters to kilometers

Distance = 150/1000 km

Distance = 0.15 km

Convert minutes to hours

Time = 1.5/60 hour

Time = 0.025 hour

The average speed is then calculated as:

Speed = Distance/Time

This gives

Speed = 0.15 km/0.025 hour

Evaluate

Speed = 6 kilometers per hour

Hence, the average speed in km per hour is 6 kilometers per hour

Find 6 / 2(9) . Express your answer as a fraction in simplest form.

Answers

Answer:

3 or 3/1

Step-by-step explanation.

since 9 is in parenthuses, do 2x9, then you have the fraction 6/18, and 6 does into 18 3 times evenly, so the answer is 3.

The simplification form of the fraction 6/2(9) is 1/3 after using the concept of fraction and basic arithmetic operation.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

The fraction is:

= 6/2(9)

From the definition of the fraction, the top of the fraction number is called the numerator and the second is the bottom of the fraction number which is called the denominator.

In the given fraction the number 6 is in the numerator and 2(9) is in the denominator.

= 6/18  (after the multiplication of 2 and 9)

= 1/3  (divide by 6 on the numerator and denominator)

Thus, the simplification form of the fraction 6/2(9) is 1/3 after using the concept of fraction and basic arithmetic operation.

Write 1/ 5 √ 7 in index form

Answers

Your answer is long see it check correctly.

The index form of the fraction  [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] where the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].

Given data:

In index form, the expression  [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] , where the base is 7 and the exponent is -1/5. This means that we are taking the reciprocal of the fifth root of 7. The exponent of -1/5 indicates that we are essentially finding the inverse of the fifth root of 7.

When dealing with fractional exponents, the denominator of the fraction becomes the root, and the numerator becomes the power to which the base is raised. In this case, the base is 7, the denominator is 5, and the numerator is -1. So, [tex]7^{(\frac{-1}{5})}[/tex]  represents the reciprocal of the fifth root of 7, which can also be expressed as the fifth root of 7 raised to the power of -1.

Hence, the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].

Step-by-step explanation:

The three pairs of corresponding angles have the same measures, so the triangles are similar by AA similarity. However, at least one pair of corresponding sides must be shown congruent before the triangles can be declared congruent.

There is nothing in the diagram to require the triangles be congruent.

With three corresponding equal angles triangles are not congruent. Therefore, the given statement is false.

What is the congruence theorem?

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

A right circular cylinder has a surface area of 66π. If the height of the cylinder is 8, find the diameter of the base.

Answers

Answer:

6

Step-by-step explanation:

h = 8

Surface area = 66π

2πr(r +h) = 66π

2πr(r + 8) = 66π

[tex]r(r + 8) =\dfrac{66\pi }{2\pi }[/tex]

r² + 8r = 33

r² + 8r - 33 = 0

r² + 11r - 3r - 33 = 0

r(r + 11) - 3(r + 11) = 0

(r +11 ) (r - 3) = 0
