Sergei is a sophomore in high school who is planning to try out for the cross country team. Only the fastest seven runners will make the varsity team, and they all run a mile in under 6:15. In eighth grade, he was able to run a mile in 9:30. After training all summer, he was able to run a mile in 8:45 his freshman year. He has been running again this summer and is getting ready for tryouts. What predictions do you think Sergei can make based on the data he has? What kind of benchmark is he measuring his performance against?

Answers

Answer:

Based on the data provided, Sergei can make the following predictions and set a benchmark for his performance:

Prediction 1: With consistent training and improvement over the summer, Sergei can predict that he will run the mile faster than 8:45 in his upcoming tryouts. This is based on the pattern of improvement he has shown from 9:30 (eighth grade) to 8:45 (freshman year) and his continued training.

Prediction 2: Sergei can aim to break the 8-minute mark for the mile based on the trend of his improvements. This is a reasonable goal given his past progress, and it aligns with his objective of making the varsity team where all runners need to run under 6:15.

Benchmark: The benchmark against which Sergei is measuring his performance is the time required to run a mile. He's tracking his progress in terms of how long it takes him to complete a mile, aiming to continuously improve and meet the varsity team's standard of running under 6:15 for the mile.

9.9g of sugar is needed for every cake made. How much sugar is needed for 8 cakes?

Answers

Answer:

79.2 g of sugar is needed.

Step-by-step explanation:

9.9 times 8 is 79.2.

You can prove this by dividing 79.2 by 8 and you will get 9.9 as the answer.

Answer:

See answer below

Step-by-step explanation:

Hi there,

Get started by developing a relationship between the amount of sugar for 1 cake. We can use dimensional analysis to solve this.

$(9.9 \ g \ sugar)/(1 \ cake)$

Now, we know that we need 8 cakes. We put 1 cake on the bottom of the fraction so that it cancels out with the 8 cakes unit:

$(9.9 \ g \ sugar)/(1 \ cake)$ $* \ 8 \ cake = 9.9 g \ sugar * 8 = 79.2 g \ sugar$

thanks,
