There are 48 DVDs of comedies and dramas on the shelf. If 25% of the DVDs are comedies, how many are dramas?
Mazyrski [523]

There are 36 drama DVD's

<em><u>Solution:</u></em>

Given that there are 48 DVD's of comedies and dramas on shelf

25 % of DVD's are comedies

To find: number of drama DVD's

Total number of dvd = 48

Number of comedy dvd = 25 % of 48

Let us find 25 % of 48

\rightarrow 25 \% \text{ of } 48\\\\\rightarrow 25 \% \times 48\\\\\rightarrow \frac{25}{100} \times 48\\\\\rightarrow 0.25 \times 48 = 12

Thus, number of comedy dvd = 12

Thus we get,

number of drama DVD's = Total number of dvd - number of comedy dvd

number of drama dvd = 48 - 12 = 36

Thus there are 36 drama dvd's

Emily is making a meal for her family. She uses coconut milk for the dessert she is making.
Artyom0805 [142]

Answer:

576 cm^3

Step-by-step explanation:

Express this volume formula as V = π r^2 h, where the " ^ " symbol indicates exponentiation.  Substitute 4 for r (this is half the diameter), 12 cm for h, and 3 for π:  V = 3*(4)^2*12 cm^3, or V = 576 cm^3.

Write each polynomial function in standard form , classify it by degree and determine the end behavior of its graph Y=12-x^4
Dmitry_Shevchenko [17]
In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0 

End behavior: 
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞
