Ella can complete the cheep cheep beatch course in 1 minute and 25 seconds. If the course is 3 laps long. How long would it take
Minchanka [31]

Answer: it will take her 56.67 seconds or 0.945 minutes to race 2 laps

Step-by-step explanation:

It takes Ella 1 minute and 25 seconds to complete the cheep beach course.

We can express this time in seconds or minutes. Expressing it in seconds,

1 minute = 60 seconds

Therefore,

1 minute and 25 seconds = 60 +25 = 85 seconds

If the course is 3 laps long, that means she completed 3 laps in 85 seconds. The time it will take her to race 2 laps would be

(2 × 85)/3

= 56.67 seconds

Converting to minutes, it will be

56.7/60 = 0.945 minutes

Write the standard form of the equation of the line through the given points.
fenix001 [56]
You first have to find the slope using the slope formula.  That looks like this with our values:  \frac{-2-(-1)}{5-(-3)}=- \frac{1}{8}.  So the slope is -1/8.  Use one of the points to first write the equation in y = mx + b form.  We have an x and a y to use from one of the points and we also have the slope we just found.  Filling in accordingly to solve for b gives us -2=5(- \frac{1}{8})+b  and  -2=- \frac{5}{8}+b.  Adding 5/8 to both sides and getting a common denominator gives us that  b=- \frac{11}{8}.  Writing our slope-intercept form we have y=- \frac{1}{8}x- \frac{11}{8}.  Standard form for a line is Ax + By = C...no fractions allowed.  So let's get rid of that 8 by multiplying each term by 8 to get 8y = -x - 11.  Add x to both sides to get it into the correct form:  x + 8y = -11
