Answer:

72 words per minute

Step-by-step explanation:

1,994 words = 27 minutes original equation

1,994/27 = 27/27 divide both sides by 27 to get 1 minute

72 words = 1 minute ; 72 words per minute

On April 11, 2012, two earthquakes were measured off the northwest coast of Sumatra. The first had a magnitude of 8.6. The secon

Hoochie [10]

Answer:

Option D. 2.51 is correct.

Step-by-step explanation:

Magnitude of first earthquake = 8.6

Let intensity of first earthquake be x

$Magnitude = \log(\frac{x}{S}),\text{ where S is seismographic factor}\\\\\implies 8.6=\log(\frac{x}{S}).......(1)$

Magnitude of second earthquake = 8.2

Let intensity of second earthquake be y

$Magnitude = \log(\frac{y}{S}),\text{ where S is seismographic factor}\\\\\implies 8.2=\log(\frac{y}{S}).......(2)$

Now, to find the factor by which intensity of first earthquake is greater than intensity of second : we divide equation (1) by equation (2)

$\implies\log(\frac{x}{y})=8.6 - 8.2\\\\\implies \log(\frac{x}{y})=0.4\\\\\implies\frac{x}{y}=10^{0.4}\\\\\implies\frac{x}{y}=2.51$

Hence the required factor is 2.51

Therefore, Option D. 2.51 is correct.

A bridge connecting two cities separated by a lake has a length of 5927.261 yd. use the table of facts to find the length of the

alex41 [277]

Answer:

the length of the bridge in miles is 3.37 miles

Step-by-step explanation:

The computation of the length of the bridge in miles is shown below:

Given that

The length is 5927.261 yard

As we know that

1760 yard = 1 mile

So 1 yard = 1 ÷ 1760 mile

For 5927.261 yard, the miles would be

= 5927.261 ÷ 1760

= 3.37 miles

Hence, the length of the bridge in miles is 3.37 miles
