. A school band sold 432 tickets for their upcoming spring concert. This represents about 85.5% of the number of tickets sold la
Law Incorporation [45]
Based on the question, we know that the
original value multiplied by .855 will equate
to 432:
ticketstastyear * 0.855 = 132
Dividing each side by 0.855 results in the
amount of tickets sold last year:
ticketslastyear ~ 505.263
We round to the nearest whole number of
505.

The answer is 505

The width of a rectangle is 4 units shorter than three-fourths the length; x. Write an expression that represents the perimeter
qaws [65]

The expression that represents the perimeter of the rectangle is 4x² + 14x - 3 = 0

<h3>How to determine the expression</h3>

The formula for perimeter of a rectangle is given as;

Perimeter = 2 ( length + width)

Let the length of the rectangle be x

Width of the rectangle be y

From the information given, we have that;

y = 4 - 3/4x

Make into linear equation

y = 16x - 3 / 4x

Now, let's substitute the variables into the formula

Perimeter = 2 (\frac{16x -3 }{4x} + x)

Find the LCM of the bracket

Perimeter = 2(\frac{16x - 3 + 4x^2}{4x} )

Perimeter = \frac{4x^2 + 16x - 3}{2x}

2x = 4x² + 16x - 3

Collect like terms

4x² + 16x - 2x - 3 = 0

4x² + 14x - 3 = 0

Thus, the expression that represents the perimeter of the rectangle is 4x² + 14x - 3 = 0

Simplify the expression c^-6 * d^4/ c^-16 * d^14​
Naily [24]

Answer:

\dfrac{c^{10}}{d^{10}}

Step-by-step explanation:

Although the way you wrote problem, this is not what it looks like, I think this is what you meant.

\dfrac{c^{-6} \times d^{4}}{c^{-16} \times d^{14}} =

= \dfrac{c^{-6}}{c^{-16}} \times \dfrac{d^{4}}{d^{14}}

= c^{-6 - (-16)} \times d^{4 - 14}

= c^{-6 + 16} \times d^{-10}

= c^{10} \times d^{-10}

= \dfrac{c^{10}}{d^{10}}
