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

31. There are C(5, 2) = 10 ways to choose 2 colors from a group of 10 colors if you don't care about the order. (Here, we treat blue background with violet letters as being indistinguishable from violet background with blue letters.)

Only one of those 10 pairs is "B and V", so the probability is 1/10.
   a) P(B and V) = 10%


32. The 12 inch dimension on the figure is 0 inches for the cross section. The remaining dimensions of the cross section are 
   c) 5 in. × 4 in.


_____
C(n, k) = n!/(k!·(n-k)!)
C(5, 2) = 5!/(2!·3!) = 5·4/(2·1) = 10

Fill in the Blanks
tatyana61 [14]

Answer: This would fill 4 and 4/9 containers.

Explanation:

Since we have given that

Quantity of walnuts in a container is given by

6\frac{2}{3}=\frac{20}{3}\ pounds

Quantity of walnuts which divided equally into containers is given by

1\frac{1}{2}=\frac{3}{2}\ pounds

Now, number of containers they would fill is given by

\frac{\frac{20}{3}}{\frac{3}{2}}=\frac{20\times 2}{3\times 3}=\frac{40}{9}

When we change it into mixed fractions we get,

\frac{40}{9}=4\frac{4}{9}

So, blank will be filled with '4'.
