Answer:

the intensity increases by a factor of 10, the Ritcher scale uses a logarithm with base 10. For example an earthquake with magnitude 2 is 10^2 times more intense than a standard earthquake, while an earthquake with magnitude 3 is 10^3 times more intense than a standard earthquake, and 10^3 = 10^2 • 10

Step-by-step explanation:

Answer:

Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to approximately a doubling of the energy released.

The Jackson's dinner cost $125. They left $21.25 as a tip. What was the percentage of the tip? Please explain and help me! THANK
fiasKO [112]

Answer:

17%

Step-by-step explanation:

to find the percentage of something, you have to fill out the following formula:

x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:

125x = 2125

then you have to divide, to single out x:

the answer is 17

so it is 17%

Express sin UU as a fraction in simplest terms.
alukav5142 [94]

The expression of sinU as a fraction is 12/13

Find the diagram attached.

To get the fraction represented by sinU, we will use the SOH CA TOA identity.

From the diagram;

  • Hypotenuse = SU = 13
  • Opposite = ST = 12 (angle opposite to m<U)

Since sin theta = opp/hyp

SinU = ST/SU

SinU = 12/13

Hence the expression of sinU as a fraction is 12/13

the nutrition facts label from a 12 oz can of soft drink is shown below. Note that a serving of the soft drink is defined as 8 o
Nataliya [291]

The correct answer is C. 65

Explanation:

The serving size of the soft drink is 8oz, besides this, the amount of sugar for this serving size according to the label is 26 grames. Now, to calculate the amount of sugar in 20oz, one of the simplest methods is to use a rule of three, because three values are known, and one is missing. The process is shown below:

1. Write the known values and use x to represent the unknown values

8 oz  =  26 grames of sugar      

20 oz  =  x

2. Use cross multiplication (this means multiply 8 x 6) and divide it into the remaining value

x = \frac{26 x 20}{ 8}   or  x = 26 x 20 / 8

3. Solve the equation

x =\frac{520}{8}      or x = 520 / 8

x = 65

The surface area of the box will be 112 in²

Explanation

According to the given diagram, the shape of the box is Right Rectangular prism.

The formula for the surface area is :

A= 2(w*l+h*l+h*w) , where l= length, w= width and h= height of the rectangular prism

Given in the diagram that, l= 8, w=4 , h=2

So, plugging the values into the formula...

A= 2(4*8+2*8+2*4)\\ \\ A= 2(32+16+8)\\ \\ A=2(56)\\ \\ A=112

So, the surface area of the box is 112 in²

What is the volume if the density of an object is 3.0g/mL and the mass is 15.0g?
adelina 88 [10]
The volume would be 5 because in order to find volume you need to divide mass over density. V=m/d
