Answer:
B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
The ratio between the two variables is a constant called constant of proportionality k

<u><em>Verify each case</em></u>
A) Julie sold 4 necklaces for $12 and 9 necklaces for $25.

Multiply in cross
Is not true
therefore
The situation not represent a proportional relationship
B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

Multiply in cross
Is true
therefore
The situation represent a proportional relationship
C) Larry packed 24 apples in 6 boxes and 46 apples in 9 boxes

Multiply in cross
Is not true
therefore
The situation not represent a proportional relationship
D) Allie put 14 pieces of candy in 2 bags and 30 pieces of candy in 4 bags

Multiply in cross
Is not true
therefore
The situation not represent a proportional relationship
Answer:
Hey Friend.....
Step-by-step explanation:
This is ur answer....
<h3>
<em>68 + 52 = 120</em></h3><h3>
<em>Sum of Triangle = 180 </em></h3><h3>
<em>Value of Interior Angle = </em></h3><h3>
<em>180 - 120 </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>= 60</em></h3><h3>
<em>Supplementary Angle Measure </em><em>=</em><em> </em><em>180 </em></h3><h3>
<em>= 180 - 60 </em></h3><h3>
<em> </em></h3><h3>
<em>Value of F Angle = 120</em></h3>
