Answer:
13 1/3 cups
Step-by-step explanation:
We assume flour is proportional to cookies, so we have ...
cups/dozens = x/10 = 4/3
Multiplying by 10 gives ...
x = 40/3 = 13 1/3
13 1/3 cups of flour are needed for 10 dozen cookies.
Infinitely many ways!
Suppose you have the fraction 2/d.
<span>Pick </span>any<span> pair of integers a and b where b ≠ 0.</span>
Then 2b-ad is and integer, as is bd so that (2b - ad)/bd is a fraction.
Consider the fractions a/b and (2b - ad)/bd
<span>Their sum is </span>
a/b + (2b-ad)/bd = ad/bd + (2b-ad)/bd = 2b/bd = 2/d - as required.
<span>Since a and b were chosen arbitrarily, there are infinitely many possible answers to the question.</span>
Ok first we calculate the length of board without losses:
4 * 11.5 = 46 inches
then, we have 1 inch of waste allowed fir each piece, so the total waste is 4*1 = 4 inches
finally, we will add the length of the waste to the desired length to get the total length of the board as follows:
total length of board = 46+4 = 50 inches
SOLUTION:
16% of 44 = 44 × 16% OR 44 × 16 / 100 OR 44 × 0.16
16% of 44 = 7.04
16% of 44 = 7.0 ( rounded to the nearest tenth )
Hope this helps! :)
Have a lovely day! <3
