There are 14 floors in the building, because since Juan went up 4 floors, down 3 floors, and up one floor; so we know that he is 2 floors above from where he originally started. Once he went down 9 floors he passed the starting point and went to the bottom of the building. So, the middle must have been the 7th floor. Once I knew that I multiplied 7*2 and it got me 14. So in total there are 14 floors. I hope this helped ^^
You need 1/12 cups of additional broth. To get this answer, you first need to find the least common multiple of the denominators. So, the LMC of 3 and 4 is 12. Multiply the top and bottom of the fractions so that they share the same denominator. Multiplying 3/4 with a 3 on both the numerator and denominator gets you 9/12 while multiplying 2/3 with a 4 on both the top and bottom gets you 8/12. After that, subtract 8/12 from 9/12 to get 1/12.
The statements expresses as
w <span>∝ b
where w = body's weight, b = amount of blood
Changing it into a direct variation becomes
w = kb or k = w/b
where k = proportionality constant
We know that k is obviously constant, we equation it into two states as
w</span>₁/b₁ = w₂/b₂
Given that w₁ = 160 lb, b₁ = 4.6 qt, b₂ = 175, w₂ = 175 lb. Then b₂ will be
160/4.6 = 175/b₂
b₂ = 160/(4.6*175) = 160/805 = 0.20 quarts
Your questions are integrated in just step-by-step solution.
Answer:
B) 1 8/27
Step-by-step explanation:
First, change all mixed fractions into improper fractions:
2 1/3 = 7/3
1 4/5 = 9/5
7/3 ÷ 9/5
Next, flip the second fraction, and change the division sign into multiplication:
7/3 x 5/9
Multiply across:
7/3 x 5/9 = 35/27
Change into a mixed fraction:
35/27 = 27/27 + 8/27
1 8/27 is your answer.
