Answer:

Relative Size, S, is 1584.89


Step-by-step explanation:

The equation is R=log_{10}(S)

Where,

  • R is the measurement in Richter Scale
  • S is the relative size of the earthquare

<u>It is given that in Richter Scale, an earthquake measured 3.2, so R=3.2.</u>

<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

R=log_{10}(S)\\3.2=log_{10}(S)

<em>Converting to exponential form, we have:</em>

3.2=log_{10}(S)\\S=10^{3.2}\\S=1584.8932

<em>Rounding to nearest hundredth, we have:</em>

S=1584.89

If tu=18 and u=11 what is tv
yuradex [85]

If the point U is between points T and V, then the numerical length of TV is 29 units

<h3>How to determine the numerical length of segment TV?</h3>

From the question, we have the following lengths that can be used in our computation:

  • Length TU = 18 units
  • Length UV = 11 units

The above parameters and representations implies that the point U is between endpoints T and V

This also means that the length TV is longer than the other lengths TU and TV

So, we have the following length equation

TV = TU + UV

Substitute the known values in the above equation

So, we have the following equation

TV = 18 + 11

Evaluate the sum of the like terms in the above equation

So, we have the following equation

TV = 29

Hence, the numerical length of segment TV is 29 units

Which of the following lines has a slope of -1/3 and a y-intercept of 6? x - 3y = 6 x + 3y = 18 3y - x = 18
erastovalidia [21]
The second choice is correct, but I believe that either its +1/3 ( in the question) or -3y as that will give you the answer of: y=1/3x+6

Alonzo will participate in a charity walkathon.Her Mother will donate $10 for Alonzo participation plus and additional $2 for ea
umka2103 [35]

Answer:

Total donation by Alonzo's mother = $40.

Step-by-step explanation:

Complete Question.

Alonzo will participate in a charity walkathon.Her Mother will donate $10 for Alonzo participation plus and additional $2 for each mile that Alonzo walks.

If Alonzo walks 15 miles, What will be the amount of her mother’s donation?

Alonzo's mum donates $10 for participation and an additional $2 per mile.

Alonzo walks 15 miles, this translates to an additional donation of (15×$2) = $30

Total donation by Alonzo's mother = $10 + $30 = $40.

Hope this Helps!!!
