Answer:
-1/2
Step-by-step explanation:
n-1 is sequence number minus one so that is three. now you have 2 to the power of three which is 8 and 8 time -1/16 is negative 1/2
So white flour to whole wheat is 2:3, and wheat flour is 60 cups.
Lets put it this way, 2 white flour = 3 wheat flour
If we have 60 cups of wheat flour, we are multiplying the above equation by 20 to get 3 x 20 - 60 cups of wheat flour.
2 white flour = 3 wheat flour (times 20 is 60, which is what they're asking)
Now we need to multiply 20 on both sides, because what you do on one side must be done to the other.
2 white flour = 3 wheat flour
x 20 x 20
40 white flour = 60 wheat flour
The final answer should be 40 cups of white flour is needed when the recipe uses 60 cups of wheat flour.
Hope this helps! :)
Answer:
63m
Explanation:
We are given the following in the question:
Average speed of swimming = 45 m/min
Time = 1 minute 24 seconds
Converting time into minutes:
1 + 24/60 = 1.4 minutes
Distance: 45 × 1.4 = 63m
