Answer:

336 purple tiles

Step-by-step explanation:

Let the number of tiles for each row be =  48 tiles

The number of rows                                =     8 rows

number of white tiles per row                 = 6 tiles

total number of white tiles                       = 8 * 6

                                                                   = 48 tiles

the total number of tiles  = 48* 8 = 384

number of purple tiles = 384 - 48\\= 336 tiles

The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, where I is the intensity of the
uranmaximum [27]

The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is \rm M = log\left ( \dfrac{10S}{S}\right ).

Given

The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a "standard" earthquake, which is barely detectable.

<h3>The magnitude of an earthquake</h3>

The magnitude of an earthquake is a measure of the energy it releases.

For an earthquake with 1,000 times more intense than a standard earthquake.

The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is;

\rm M =log \dfrac{I}{S}\\\\M = log \dfrac{10s}{s}\\\\M=log 10\\\\M =1

Hence, the equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is \rm M = log\left ( \dfrac{10S}{S}\right ).

Simplify completely quantity x squared plus 4 x minus 45 all over x squared plus 10 x plus 9 and find the restrictions on the va
Brums [2.3K]

Answer:

A) Quantity x minus 5 over quantity x plus 1, where x≠-1 and x≠-9

Step-by-step explanation:

\frac{x^2 + 4x - 45}{x^2 + 10x + 9}

Simplifying the numerator first:

x² + 4x - 45 using the quadratic formula you get;

(x - 5)(x + 9)

Then simplifying the denominator x² + 10x + 9 using a quadratic formula you get;

(x + 1)(x + 9)

Dividing the numerator and denominator now gives;

\frac{(x - 5)(x + 9)}{(x + 1)(x + 9)}

Cancelling (x + 9) throughout leaves you with;

\frac{x - 5}{x + 1}

The only restrictions here is if x = 1 and 9 which will give an undefined answer.

Antonio orders an iPhone case off of Amazon for $27. He has to pay an additional 3% for shipping and handling. How much will his
Wewaii [24]

Answer:

We conclude that total cost/bill will be: $27.81  

Step-by-step explanation:

Given

The cost of an iPhone case = $27

Additional expense = 3% = 3/100 = 0.03

To determine

Total bill = ?

The expense amount can be calculated by multiplying the cost of an iPhone case by the additional expense

i.e.

Expense Amount = cost of an iPhone case × additional expense

                             = 27 × 0.03

                             = $0.81

The total cost is calculated by adding the expense amount and the original cost of an iPhone case.

i.e.

Total cost/bill = Expense Amount + cost of an iPhone case

                  = $0.81 + $27

                  = $27.81

Therefore, we conclude that total cost/bill will be: $27.81
