Question 1

Mathematics
1 answer:
natima [27]3 years ago
6 0

Answer:

Yes, her reasoning is correct

Step-by-step explanation:

Given the ratio:  109.2 : 6

Written in fractional form, we have:

109.2: 6=\dfrac{109.2}{6}

Now:

\dfrac{109.2}{6}=\dfrac{109.2}{6}X1, $  Let 1=\dfrac{10}{10}, \\\\=\dfrac{109.2}{6}X\dfrac{10}{10}\\\\=\dfrac{1092}{60}

Therefore, the student's reasoning is correct. In fact, as a check:

\dfrac{109.2}{6}=18.2\\\\\dfrac{1092}{60}=18.2

We would obtain the same result in both cases.

kirza4 [7]

44 identical red wooden blocks can be arranged in 44! ways

99 identical white wooden blocks can be arranged in 99! Ways

If the 44 red blocks and the 99 white blocks are to be stacked on top of one another, the number of different color patterns that can​ result = 44! x 99!

 

44! = 2.65827157 x 10^54

99! = 9.33262154 x 10^155

44! x 99! = 2.48086426 x 10^210

 

Therefore, 2.48086426 x 10^210 different color patterns can ​result
