Help me please with this question

Mathematics
1 answer:
kirill115 [55]4 years ago
3 0

Answer:

  5.0

Step-by-step explanation:

If we call the intensity of the larger quake I2, and that of the smaller quake I1, then we want to find I2/I1.

The log of that ratio is given by ...

  log(I2/I1) = log(I2) -log(I1)

  = R2 -R1

  = 8.2 -7.5

  log(I2/I1) = 0.7

Taking antilogs, we have ...

  I2/I1 = 10^0.7

  I2/I1 = 5.0

The stronger quake is 5.0 times as intense as the lesser one.

Solve tor r.<br> *a(5 – x) = bz - 8
Mars2501 [29]

Answer:

See explanation

Step-by-step explanation:

Assuming the given equation is

a(5 - r) = bz - 8

To solve for r, we first divide both sides by a.

5 - r = \frac{ bz - 8}{a}

We now subtract 5 from both sides:

- r = \frac{ bz - 8}{a}  - 5

We now divide through by - 1 to get:

r = 5 - \frac{ bz - 8}{a}

Or

r = \frac{5a -  bz + 8}{a}  \:  \: where \: a \ne0

Marcus bought a booklet of tickets to use at the amusement park. He used 50% of the tickets on rides, 13of the tickets on video
baherus [9]

Given :

Marcus bought a booklet of tickets to use at the amusement park.

He used 50% of the tickets on rides, 13% of the tickets on video games, and the rest of the tickets in the batting cage.

To Find :

Marcus says he used 10% of the tickets in the batting cage.

Solution :

We know sum of all the percentage should be equal to 100.

So,

( % used on rides ) + ( % used on video game ) + ( % used in batting cage ) = 100

Let, % of ticket spend on batting cage is x.

50 + 13 + x = 100

x = 100 - ( 50 + 13 )

x = 37%

So, Marcus used 37% in batting cage.

Therefore, the statement by Marcus that he use 10% of the ticket in the cage is wrong.
