A = Sock's weight
b = Princess' weight
c = Luna's weight
a : b = 4 : 5
b : c = 6 : 7
at this point, we have to change the 2 ratios (a : b and b : c) into one ratio (a : b : c)
to do that, we have to change the ratio number so the number b in both ratio is the same
a : b = 4 : 5 = 24 : 30
b : c = 6 : 7 = 30 : 35
From that we can conclude that
a : b : c = 24 : 30 : 35
Since we're looking for the ratio of Sock's weight to Luna's weight, it will be
a : c = 24 : 35
Answer:
s₁ = 2 m/s
Step-by-step explanation:
given,
distance between Melissa and friend = 3 mile
walking speed = s₁
bike speed = s₂
total time of the trip = 2 hour
given,
s₂ = s₁ + 4
2(s₁ +4)s₁ = 3 (s₁ + s₁ + 4)
2 s₁² + 8 s₁ = 6 s₁ + 12
s₁² + s₁ - 6 = 0
s₁² + 3 s₁ - 2 s₁ - 6 = 0
(s₁ + 3) (s₁ -2) = 0
s₁ = -3 , 2
s₁ = 2 m/s
walking speed of the Melissa is s₁ = 2 m/s
Answer:
-7/12
Step-by-step explanation:
15/4 simplified is 3 3/4
so 3 3/4 - 4 1/3
this equals -7/12
Answer:
B) - The Viceroy population remained fairly steady over the three years recorded.
C) - The average number of Zebra Swallowtails over all three samples will be less than the number recorded in year 1.
D) - If a population is increasing over time, the average will be less than the most recent count.
Step-by-step explanation:
just got it right on the test
15p + 3(p-1) > 3(2^3)
15p + 3p - 3 > 3(8)
18p - 3 > 24
18p > 24 + 3
18p > 27
p > 27/18
p > 3/2 or 1 1/2
