Answer:
<u>The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.</u>
Step-by-step explanation:
Let's find out the pattern Zack is using to water his garden, this way:
First week = 1 3/8 gallons of water
Second week = 1 3/4 gallons of water = 1 3/8 + 3/8 = 1 6/8 = 1 3/4
Third week = 2 1/8 gallons of water = 1 3/4 + 3/8 = 1 6/8 + 3/8 = 2 1/8
The constant of adding every week is 3/8 gallons, therefore,
Fourth week = 2 1/8 + 3/8 = 2 4/8 = 2 1/2 gallons of water
Fifth week = 2 1/2 + 3/8 = 2 4/8 + 3/8 = 2 7/8 gallons of water
<u>The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.</u>
Answer:
Step-by-step explanation:
22. √125 is closer to √121 or 11
23. √23.5 is closer to √25 or 5
24. ∛59 is closer to ∛64 or 4 (cubed)
(4 cubed = 64, 3 cubed = 27)
25. ∛430 is closer to ∛512 or 8
(512 - 430 = 82
430- 343= 87)
26. y² = 55 is equal to y = √55, Closer to √49 or 7
27. d² = 95 is equal to d = √95, Closer to √100 or 10
28. p² = 6.8 is equal to p = √6.8, Closer to √9 or 3
29. ∛210 is closer to ∛216 or 6 (cubed)
30. ∛520 is closer to ∛512 or 8 (cubed)
Answer:
12/30
Step-by-step explanation:
So we know that the denominator-numerator=18
And we also know that it's equal to 4/10 or 2/5.
Soooooooooooooo the most easiest is just to trial and error: 12/30
But I don't really know the more complex formula...
