In a store, 9/200 of the shirts are pink and 69/600 are orange. What percent of the shirts are not pink or orange?​
pychu [463]

Answer:

84%

Step-by-step explanation:

The percentage of pink shirts

= 9/200 × 100%

= 9/2

= 4.5%

The percentage of orange shirts

= 69/600 × 100%

= 69/6

= 11.5%

The percentage of the shirts which are not pink or orange

= 1 - 4.5% - 11.5%

= 84%

<u>Alternative</u>

Find their common denominator.

9/200

= 9×3 / 200×3

= 27/600

The total percentage of shirts in pink and orange

= (27/600 + 69/600) × 100%

= 96/600 × 100%

= 16%

The percentage of the shirts which are not pink or orange

= 1 - 16%

= 84%

If f(x) = 2x^4, then f'(3) =
valkas [14]

To find f'(3) (f prime of 3), you must find f' first.  f' is the derivative of the function f(x).

Finding the derivative of f(x) = 2x⁴ requires the use of the power rule.

The power rule for derivatives is \frac{d}{dx} [x^{n} ] =nx^{n-1}.  In other words, you bring the exponent forward and multiply it by the coefficient of the term, and then you subtract 1 from the original exponent.

f'(x) = \frac{d}{dx}(2x⁴)

f'(x) = 2(4)x³

f'(x) = 8x³

Now, to find f'(3), plug 3 into your derivative.

f'(3) = 8(3)³

f'(3) = 216

<h3>Answer:</h3>

f'(3) = 216

Mrrafil [7]

Answer:

sadia is 32

Step-by-step explanation:

sadia : father : total

3          6          9

Divide 96 by 9

96/9 = 32/3

Multiply each by 32/3

sadia :     father : total

3*32/3    6*32/3  9*32/3

32                 64          96

ExtremeBDS [4]
75.
Explanation: from 3 to 12, you add 9, and then double the 12 to get to 24, and then add 9 again to get to 33, and double it to get 66, so the pattern is to add 9 and then double.
