Mrs. roberts poured 2 glasses of lemonade. the first glass contained 5 oz of lemon juice and 8 oz of water. the second glass contained 3 oz of lemon juice and 7 oz of water. which glass of lemonade had a stronger lemon flavor? show me or explain to me how you know. (prove to me that your answer is correct! )

The first glass

Step-by-step explanation:

I believe that first, you must find the ratio of lemonade to water in each glass.

[Remember that you can write a ratio in 3 ways (assume that x and y are numbers):

x : y

x / y

x  to  y

Now, our first glass of lemonade can be written as 5/8. If you were to write 5/8 as a decimal, you'd get 0.625.

Now, our second glass of lemonade can be written as 3/7. If you were to write 3/7 as a decimal, you'd get 0.428 (I rounded it to the nearest thousandth.)

0.625 > 0.428

0.625 is greater than 0.428, so therefore, the first glass had a stronger lemon flavor.

I hope this helps! :)

Step-by-step explanation:

The first glass has a total volume of 5 oz + 8 oz = 13 oz.  Of the 13 oz, 5 oz is lemon juice, so the fraction of lemon is 5/13.

The second glass has a total volume of 3 oz + 7 oz = 10 oz.  Of the 10 oz, 3 oz is lemon juice, so the fraction of lemon is 3/10.

We need to compare these fractions.  To do that, we need to find the common denominator.  In this case, 10×13 = 130.

5/13 = 50/130

3/10 = 39/130

So the first glass has the stronger lemon flavor.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
