The Richter scale magnitude reading m is given by m=log10x , where x represents the amplitude of the seismic wave causing ground motion. Determine the reading of an earthquake that is 10 times less intense than an earthquake that measures 4.5 on the Richter scale.

Answers

Answer 1

Answer: The reading would be 5.5 on the Richter scale.

Step-by-step explanation:

The intensity of an earthquake that measures 4.5 on the Ritcher scale can be found by solving:

4.5 = log₁₀(x)

for x.

remember that:

logₐ(x) = ln(x)/ln(a)

Then we can rewrite our equation as:

4.5 = ln(x)/ln(10)

4.5*ln(10) = ln(x)

we also know that:

ln(exp(x)) = exp(ln(x)) = x

Then we can apply the exponential equation to both sides to get:

exp( 4.5*ln(10)) = exp( ln(x) ) = x

exp( 4.5*ln(10)) = x

x = 31,622.8

Now, if we have an intensity 10 times larger than this, we will have:

x = 10*31,622.8 = 316,228

The reading on the Richter scale will be:

m = Log₁₀(316,228) = 5.5

what is the total surface area of a cylinder with a base of 11m and a height of 7m

Answers

Answer:

V = 1692.46 m3

Step-by-step explanation:

V = π· r2· h

V = π· 72· 11

V = 1692.46 m3

Answer:

Step-by-step explanation:

A=2*π*r*h+2*π*r^2    ( This is the formula for surface area of cylinder )

As given

base = 11m    so we have to get the radius = 11/2 = 5.5m

height=7m

now putt in formula, we get

=2*π·*(5.5)*(7)+2*π*(5.5)^2

=431.96899m^2

Step-by-step explanation:

Question A:

The formula to find the hypotenuse is c²=a²+b²

So you would insert the numbers into the formula which would be c²=8²+6²

8²=64

6²=36

36+64=100

So c²=100

Then you want to find c on its own so you have to square root 100.

The square root of 100 is 10.

You have to use this method for the rest of the triangles.

The hypotenuse of the triangles are solved

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

a)

a = 8

b = 6

Now , From the Pythagoras Theorem , The hypotenuse² = base² + height²

c = √ ( 8 )² + ( 6 )²

c = √100 ≈ 10

b)

a = 11

b = 7

c = √170 ≈ 13.0

c)

a = 13

b = 6

c = √205 ≈ 14.3

Hence , the hypotenuse of the triangles are solved

2/5 x 5/4 in fraction in its simplest form​

Answers

Answer:

The answer is 1/2. When you multiply the numerator and denominator, you get 10/20. If you divide the top and bottom by 5, you get 1/2.

The equivalent value of the fraction is A = 1/2 = 0.5

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first fraction be p

Let the second fraction be q

Now , A = pq

when the value of p = 2/5

And , when the value of q = 5/4

On simplifying the equation , we get

A = ( 2/5 ) ( 5/4 )

So , the left hand side of the equation is equated to the right hand side by the value of ( 2/5 ) ( 5/4 )

A = ( 2/5 ) ( 5/4 )

A = ( 2 x 5 ) / ( 5 x 4 )

On simplifying , we get

A = 10/20

Divide by 10 on the numerator and denominator of the fraction , we get

A = 1/2

A = 0.5

Therefore , the value of A = 1/2 = 0.5

Hence , the fraction is A = 1/2 = 0.5
