Answer:
Option (3) 
Step-by-step explanation:
Track is shaped as a rectangle with a semicircle on either side.
Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.
= 2(96) + 2πr
= 
= 192 + 35π
= 192 + 109.9
= 301.9 m
Since, Jake plans to run four laps.
Therefore, distance covered by Jake = 4 × 301.9
                                                               = 1207.6 m
Option (3) will be the correct option.

<u>Algebra I</u>
- Terms/Coefficients
- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = -4x + 1
11y = x + 146
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>:                                                                                                  11(-4x + 1) = x + 146
- Distribute 11:                                                                                                      -44x + 11 = x + 146
- [Addition Property of Equality] Add 44x on both sides:                                11 = 45x + 146
- [Subtraction Property of Equality] Subtract 146 on both sides:                      -135 = 45x
- [Division Property of Equality] Divide 45 on both sides:                              -3 = x
- Rewrite/Rearrange:                                                                                          x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation:                                                                                 y = -4x + 1
- Substitute in <em>x</em>:                                                                                                 y = -4(-3) + 1
- Multiply:                                                                                                           y = 12 + 1
- Add:                                                                                                                    y = 13
 
        
             
        
        
        
Answer:
i. x and a are increasing while y and b are reducing
 
        
             
        
        
        
Since we are dealing with a volume problem (3 dimensions) when you increase the radius by a factor of 2, you increase the volume by a factor of 2^3 or 8
So, the larger sphere has a volume 8 times greater than the smaller sphere.
