A rain gutter is to be constructed of aluminum sheets 12 inches wide. After marking off a length of 4 inches from each edge, this length is bent up at an angle θ. The area A of the opening may be expressed as the function: A(θ) = 16 sin θ ⋅ (cos θ + 1). If θ = 60°, what is the area of the opening?

Answers

A(45degrees) = 16sin(45)(cos(45)+ 1)
                         = 16(1/sqrt2)(1+1/sqrt2)
                         = 16(1/sqrt2)(1+ sqrt2) /sqrt2
                         = 16(1+sqrt2) /2
                         = 8 + (sqrt2)/2in^2
 

Write 3 2/3 as improper fraction

Answers

The answer is 11/3. Multiply the denominator (3) by the whole number (3), add the numerator (2), then keep the denominator the same! You should end up with 11/3.

The improper fraction of 3(2)/(3) is ⇒ 10/3.

 

The given mixed fraction is

3(2)/(3)

We know that

Every fraction is made up of two parts: the numerator and the denominator. Proper fractions and improper fractions are the two primary forms of fractions in mathematics depending on the numerator and denominator values.

An improper fraction is a type of fraction where the numerator is greater than or equal to the denominator

In order to convert it improper fraction proceed as follow

3(2)/(3)

= (3x3 + 1)/3

= (9+1)/3

= 10/3

Thus improper fraction is 10/3

Very simple challenge hard question

Answers

Answer:

-58.41509433

Step-by-step explanation:

0.4+8(5-0.8*5/8)-5/(2.5)=34.4

[0.4+8(5-4/8)-(2)]=

[0.4+8(40-4)/8)-2=34.4 ( nominator)

15-(8.9-2.6/(2/3))*34*2/5 =-53

15-(8.9-3.9)*68/5

15-5*68/5=

15-68=-53 ( denominator)

(34.4/-53) *90

If QRST is a rectangle, find the value of x if angle Q is equal to 5x+30

Answers

A rectangle is a four-sided flat shape where every angle is a right angle (90°). 

QRST = 90^0 

5x + 30 = 90   

5x = 60    

5x = 60 / 5

x = 12
If QRST is a rectangle then Q = 90°.

Threfore

5x + 30 = 90    |subtract 30 from both sides

5x = 60    |divide both sides by 5

x = 12
