The answer is 77/60. 

When dividing 2 fractions the way I learned was to multiply the first fraction with the reciprocal of the second number. 

so it would be 11/12 x 7/5

and when you multiply that you get 77/60

Find the angle between the vectors u=i-9j and v=8i+5j
Katyanochek1 [597]

Answer: \cos^{-1} \left(\frac{-37}{\sqrt{7298}} \right) \approx 115.665^{\circ}

Step-by-step explanation:

u \cdot v=(1)(8)+(-9)(5)=-37\\\\|u|=\sqrt{1^{2}+(-9)^{2}}=\sqrt{82}\\\\|v|=\sqrt{8^{2}+5^{2}}=\sqrt{89}\\\\\cos \theta=\frac{-37}{\sqrt{82}\sqrt{89}}\\\\\theta=\cos^{-1} \left(\frac{-37}{\sqrt{82}\sqrt{89}} \right)\\\\\theta=\boxed{\cos^{-1} \left(\frac{-37}{\sqrt{7298}} \right) \approx 115.665^{\circ}}

10. Make Sense and Persevere The flag of the
kumpel [21]

Answer:

  • s=\frac{P}{3}
  • Dimensions of the flag:

       lenght=6.65\ ft\\\\width=3.5\ ft

  • Area of the flag: 23.275\ ft^2

Step-by-step explanation:

<em><u>The missing figure of the exercise is attached.</u></em>

<em><u /></em>

We know that the perimeter of the triangle is given by:

P= 3s

Where "s" is the side lenght of the triangle.

Solving for "s", we get:

s=\frac{P}{3}

Therefore, if the perimeter of the triangle is 126 inches, its side length is:

s=\frac{126\ in}{3}\\\\s=42\ in

 Since  1\ ft=12\ in, we know that "s" in feet is:

s=(42\ in)(\frac{1\ ft}{12\ in})=3.5\ ft

The area of a rectangle can be calculated with this formula:

A=lw

Where "l" is the lenght and "w" is the width

We can observe in the figure that the lenght and the width of the flag are:

l=1.9s\\w=s

Then, the dimensions of the flag are:

l=1.9(3.5\ ft)=6.65\ ft\\w=3.5\ ft

And the area is:

A=(6.65\ ft)(3.5\ ft)=23.275\ ft^2
