a_sh-v [17]

Answer:

10

Step-by-step explanation

The earthquake  measures 6.4 on the Richter scale which struck Japan in Jullu 2007 and caused and extensive damage. Earlier that year, a minor earthquake measuring 3.1 in the Richter scale has stroked in parts of Pennsylvania.

Fomular:

The magnitude of an earthquake is M log(I/S)

where I donates the intensity of the earthquake and S be the intensity of the standard earthquake.

Calculation:

Consider that M1 be the magnitude Japanese earthquake and M2 be the magnitude of the Pennsylvania earthquake and L1 be the intensity of the Japanese earthquake and L2 the intensity of the Pennsylvania  earthquake.

Here the magnitude of the Japanese earthquake is M1 = 6.14 and the magnitude of the Pennsylvania is M2 = 3.1

By the use of magnitude of the earthquake fomular M = log I1/S, the intensity of the Japanese earthquake is calculated as follows .

M1 = log I1/S

I1/s = 10

The variables y and x^2 are directly
choli [55]

Answer:

y = \frac{20}{21} x²

Step-by-step explanation:

Given that y and x² are directly proportional then the equation relating them is

y = kx² ← k is the constant of proportion

When x = 2

y = k × 2² = 4k

When x = 5

y = k × 5² = 25k

Then

25k - 4k = 20 ( difference between values is 20 )

21k = 20 ( divide both sides by 21 )

k = \frac{20}{21}

y = \frac{20}{21} x² ← equation of proportion

The New York Queens Zoo celebrated the birth of a Southern pudu deer in July of 2013. The doe is a member of the world’s smalles
PolarNik [594]

The pudu weighed approximately 1 pound at birth.

Given that the New York Queens Zoo celebrated the birth of a Southern pudu deer in July of 2013 which tipped the scale of a mere 0.45 kg, to determine, given that one kilogram is approximately equal to 2.2 pounds, about how many pounds did the pudu weigh at birth, the following calculation must be performed:

  • 1 = 2.2
  • 0.45 = X
  • 0.45 x 2.2 = X
  • 0.99 = X

Therefore, the pudu weighed approximately 1 pound at birth.
