3 0

Answer:

60

Step-by-step explanation:

to find w:

sin(44) = w/30

w = 30sin(44)

w = 20.8 to 1 decimal place

to find x;

cos(x) = 20.8/45

x = cos^{-1}(20.8/45)

x = 62.46940334

x = 60

Question
Alik [6]

Here, we are required to find the equation, in terms of w, that could be used to find the dimensions of the storage unit in feet.

The polynomial is;. 3w³ + 22w + 24w = 5440ft³.

From the question;

  • <em>Let the width = w</em>
  • <em>length,</em><em> </em><em>l</em><em> = 3w + 4</em>
  • <em>height,</em><em> </em><em>h</em><em> = w + 6</em>

<em>The </em><em>volume </em><em>of </em><em>a </em><em>rectangular</em><em> </em><em>prism </em><em>is </em><em>given </em><em>by </em><em>the </em><em>product </em><em>of </em><em>its </em><em>length,</em><em> </em><em>width </em><em>and </em><em>height.</em><em> </em><em>Thus</em><em>;</em>

Volume = l × w × h

Therefore, Volume, V = (3w +4) × w × (w +6)

To obtain the required polynomial, we expand the expression for Volume above;

<em>V = (3w² + 4w) × (w + 6)</em>

<em>V = (3w² + 4w) × (w + 6)V = 3w³ + 22w² + 24w.</em>

However, the volume of the rectangular prism has been given to be 5440 cubic feet.

Therefore, the polynomial is;

3w³ + 22w + 24w = 5440ft³.

During a basketball practice, Mai attempted 49 free throws and was on 25% of them. How many successful free throws did she make?
Brrunno [24]

Mai made 12 successful free throws.

Step-by-step explanation:

Given,

Free throws made by Mai = 49 free throw

Successful throws = 25%

Number of successful throws = 25% of free throws

Number of successful throws = \frac{25}{100}*49

Number of successful throws = \frac{1225}{100} = 12.25

Rounding off to nearest whole number;

Number of successful throws = 12

Mai made 12 successful free throws.
