On the first math test, Keiko answered 19 out of 25 questions correctly. On the

m_a_m_a [10]

Answer:

Keiko got a better answer on the test on her second test, and you could compare these two ratios as they are written.

Step-by-step explanation:

First: Convert each of the scores into percentages:

How do you convert ratios to percentages? Well, first we have to convert the ratio to a decimal or a fraction. Let's convert it to a fraction. So, 19 out of 25 will become $\frac{19}{25}$ , and 17 out of 20 will become $\frac{17}{20}$ . To convert a fraction to a percentage:

Divide the numerator by the denominator:

19 ÷ 25 = 0.76 AND 17 ÷ 20 = 0.85

Multiply your quotient by 100

0.76 x 100 = 76 AND 0.85 x 100 = 85

Add the percent sign

76% AND 85%

Now the two quantities are easier to compare. We can obviously see that 85% is bigger [and better] than 76%. So, the ratio that equals 85% - 17 out of 20 - is a better grade.

The second question was: Can you compare these two ratios as they are written? Explain why or why not.

Yes, you can compare these two ratios, just find the [positive] difference between the amount that she scored and the total number of scores that could be gained.

25 - 19 = 6

20 - 17 = 3

Since the equation with 20 and 17 in it has a smaller difference, it is most likely to have a greater value [because that means that Keiko got more right and less wrong, which means a greater mark which is also a greater quantity].

Thanks,

The world record for the men’s 10000 meters was 26 minutes 17.53 seconds held by kenenisa bekele of Ethiopia. What was his avera

Crazy boy [7]

Answer:

6.33 m/s

Step-by-step explanation:

Given that,

The world record for the men’s 10000 meters was 26 minutes 17.53 seconds.

Distance = 10000 m

Time, t = 26 minutes 17.53 seconds = 1577.53 s

We need to find the average speed throughout the race. It is equal to total distance divided by total time taken.

$v=\dfrac{10000\ m}{1577.53\ s}\\\\=6.33\ m/s$

So, the average speed is 6.33 m/s.
