Answer:
First, 24 divided by 8 equals 3. this means you divide 12 by 3. you get 4. 4 cups of sugar will be used when 8 cups of flour are used.
Answer:
approximately 42.05
Step-by-step explanation:
We know that the distance formula is 
, so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that
x₂=3
y₂=8
x₁=21
y₁=-30
Then, we can plug it into the formula to get 
Answer:
x0 y0
Step-by-step explanation:
Using proportions, it is found that it will take you 392 seconds = 6 minutes and 32 seconds to complete 4 laps.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, considering the given rates, the time that is takes to complete one lap of 400 m is given by:
t = 2 x 12(sprint) + 24(half as fast as the sprint, 24 seconds per 100 meters) + 50 = 98 seconds.
Hence for 4 laps, the time is given by:
t = 4 x 98 seconds = 392 seconds = 6 minutes and 32 seconds to complete 4 laps.
