scoundrel [369]3 years ago

Answer:

The answer is "158.489"

Step-by-step explanation:

for san francisco earthquake:

\log(\frac{a_1}{T}) + B = 7.8\\\\\log(\frac{a_1}{T})+\log(10^{B}) = 7.8\\\\\log(\frac{a_1}{T} \times 10^{B})=7.8\\\\(\frac{a_1}{T} \times 10^B=10^{7.8}...............(i)

similarly , for coloumbia earthquake:

\frac{a_2}{T}\times 10^B = 10^{5.6}.................(ii)

divide equation (i) and (ii):

\frac{a_1}{a_2}=\frac{10^{7.8}}{10^{5.6}}\\\\\frac{a_1}{a_2}=10^{2.2}\approx 158.489

Answer:

area = (1/2)|Ax(By-Cy) +Bx(Cy-Ay) +Cx(Ay-By)|

 = (1/2)|2(3-6) +3(6-1) +1(1-3)| = (1/2)|-6 +15 -2|

 area = 7/2

if two positive integers P and Q can be expressed as p = a b square and q equals A cube B where A and B being prime numbers then
vodka [1.7K]
P = ab^2
q = a^3 b

p = a * b * b
q = a*a*a * b

Pairing the duplicates we have LCM = a*a*a*b*b  = a^3 b^2 answer

Suppose vanilla beans cost $600 per kilogram. Julie bought 9 grams of vanilla beans. Jacques bought 70 grams of vanilla beans.
GenaCL600 [577]
The Correct option is 36.60
Step-by-step explanation:
The key to solving this question lies
around measurement
conversion,specifically converting
grams into its equivalence in
kilograms.
1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg 1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg
70 grams=0.07 kg
Julie pays=$600*0.009=$5.4
Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-
$5.4) than Julie paid
Option is wrong because that was Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-
$5.4) than Julie paid
Option is wrong because that was
what Julie paid
Option D is wrong because that was
what Jacques paid
Option B is obviously wrong
