For the pan one, you would colour all 4 of them (lightly) because she used all 4. For the cutting them up one, you did it right. For the next one, the first thing you need to do is colour 1 slice on the first triangle, on the 3rd on colour 2 slices, on the 2nd one colour two slices, and on the 4th one colour 4 slices. (Colour these ones hard.)

The 2nd pan could have 1/2 left, shade in 2, ( 2/4=1/2), and the 4th pan could also have 1/2 left, shade in 4, (1/2=4/8) and for the 1/3 ones you could the 1st one, shade 1,(1/3=1/3), and the 3rd pan, shade in 2, (2/6=1/3)

carlos can write 3 to 4 pages in his journal in 2/3 hour. if he writes for 5 hours, what's a reasonable number of pages he can w

zheka24 [161]

Answer:

23, 24, 25, 26, 27, 28, 29, or 30

22.5 ≤ p ≤ 30

Step-by-step explanation:

So we know that in 2/3 hours, Carlos can write 3 to 4 pages.

First, lets find how many 2/3's are in 5. Lets divide 5 by 2/3.

$\frac{5}{\frac{2}{3}}=7.5$

So there are 7.5 2/3's in 5.

Now, lets assume Carlos writes 4 pages per 2/3 hours consistently throughout that 5 hours. This would yield the maximum amount of pages Carlos can write in 5 hours.

7.5(4) = 30

So the maximum amount of pages Carlos can write in 5 hours is 30.

Now, lets assume Carlos writes 3 pages per 2/3 hours consistently throughout that 5 hours. This would yield the minimum amount of pages Carlos can write in 5 hours.

7.5(3) = 22.5

So the minimum amount of pages Carlos can write in 5 hours is 22.5.

Now we can write the information that we found as an inequality. Lets make p equal to the pages that Carlos can write in 5 hours.

22.5 ≤ p ≤ 30

Any value greater than to equal to 22.5 and less than or equal to 30 would be reasonable.

I hope you find my answer and explanation to be helpful. Happy studying.
