Given:

Intensity of earthquake is 5011 times more than

To find:

The magnitude of an earthquake that is 5011 times more than a standard earthquake.

Solution:

The magnitude of an earthquake:

$M=\log \left(\frac{I_{1}}{I_{0}}\right)

where I_1 is the measured intensity of earthquake and

I_0 is the standard intensity of earthquake

Given 5011 times more than a standard earthquake.

I_{1}=5011 I_{0}

Substitute this into the magnitude.

$M=\log \left(\frac{5011 I_{0}}{I_{0}}\right)

Cancel both I_0 in the numerator and denominator.

M=\log (5011)

M=3.6999

M = 3.7

The magnitude of the earthquake is 3.7.

You and your friend are selling your old CDs. Your friend sells 14 the first day, and x the next day. You sell y the first day a
Deffense [45]

Answer: 30+x+y

Step-by-step explanation:

  • Commutative Property of Addition : a+b= b+a , where a and b are any arbitrary numbers.

Given : Number of CDs sold by friend on first day = 14

Number of CDs sold by friend on next day = x

Total CDs sold by friend  = 14 +x

Number of CDs sold by you on first day = 16

Number of CDs sold by you on next day = y

Total CDs sold by you  = 16+y

The expression that shows the total number of CDs sold both days =

Total CDs sold by friend  + Total CDs sold by you

=  14 +x+ 16+y

= 14 +(x+ 16)+y

= 14 +(16+x)+y   [By Commutative Property of Addition.]

= 14+16+x+y

= 30+x+y

Hence, the expression that shows the total number of CDs sold both days :

30+x+y

What is the solution to the equation?
pashok25 [27]

Answer:

x= 27

Step-by-step explanation:

Move <u>constant</u> to the right-hand side and change its sign.

\sqrt{2x+10} = 2+6

Add the numbers.

\sqrt{2x+10}= 8

Square both sides of the equation.

2x+10= 64

Move the <u>constant</u> to the right-hand side and change its sign.

2x= 64-10

Subtract the numbers.

2x= 54

Divide both sides of the equation by 2.

x= 27

Answer:

6a) 1

6b) 11

7a) 4

7b) 10

8a) 6

8b) 14

9a) 11

9b) 13

Step-by-step explanation:

In order to make a triangle, we need to follow this property:

a <= b + c

(Known as "triangle inequality")

Where 'a' is the bigger side and 'b' and 'c' are the other two sides.

So, using this property, we can solve the following problems:

6a) Maximum side will be 6:

6 <= 5 + c

c = 1

6b) Minimum sides will be 5 and 6:

a <= 5 + 6

a = 11

7a) Maximum side will be 7:

7 <= 3 + c

c = 4

7b) Minimum sides will be 3 and 7:

a <= 3 + 7

a = 10

8a) Maximum side will be 10:

10 <= 4 + c

c = 6

8b) Minimum sides will be 4 and 10:

a <= 4 + 10

a = 14

9a) Maximum side will be 12:

12 <= 1 + c

c = 11

9b) Minimum sides will be 1 and 12:

a <= 1 + 12

a = 13
