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:
w = 49
Step-by-step explanation:
w - 39 = 10
=> w = 10 + 39
=> w = 49
Answer:
1 / 16
Step-by-step explanation:
Number of options = 4
Number of correct answers = 1
Number points gained for a correct answer = 1
Number of points lost for an incorrect answer = 1/4 = 0.25
Probability of choosing a correct option = 1/4
Probability of choosing an incorrect option = 3/4
x ____ 1 ______ - 1/4
P(x) __ 1/4 ______ 3/4
Expected gain or loss :
E(x) = Σx*p(x)
E(x) = (1 * 1/4) + (-1/4 * 3/4)
E(x) = 1/4 - 3/16
E(x) = (4 - 3) / 16
E(x) = 1 /16
A gain of 1/16
Answer:
B) 5 km
Step-by-step explanation:
There are 1,000 m in 1 km, so <em>x</em> km=5000m
Set up a proportion:
![\frac{1000m}{1km}=\frac{5000m}{x km}](https://tex.z-dn.net/?f=%5Cfrac%7B1000m%7D%7B1km%7D%3D%5Cfrac%7B5000m%7D%7Bx%20km%7D)
Cross multiply and solve for "x":
(1000 m)(x km)=(5000 m)(1 km)
1000x=5000
(1000x/1000)=5000/1000
x=5 km
