The length between the bases on a Major League Baseball diamond is 90 feet. Allyson wants to make a scale drawing of a baseball
Vinil7 [7]

Answer:

\text{The scale is }\frac{1}{432}

Step-by-step explanation:

Length between the bases on a major league diamond = 90 feet

1 feet = 12 inches

90 feet = 90 × 12

             = 1080 inches

Length between the bases on a major league baseball diamond on scale drawing = 2.5 inches

\text{Scale factor = }\frac{\text{Actual length}}{\text{Scale length}}\\\\\text{Scale factor = }\frac{1080}{2.5}=432

\text{Hence, the scale is }\frac{1}{432}

Find the 107 terms of sequence -9,-5,-1,3,7​
Nikitich [7]

Answer:

415

Step-by-step explanation:

the nth term of the sequence is -13 + 4n

the sequence is an arithmetic progression with nth term a + (n - 1)d

a = -9, d = a5- a4 = 7 -3 =4

nth = -9 + (n -1) 4

       = -9 + 4n -4

       = -13 + 4n

hence the 107th term; -13 + 4*107

                                      -13 + 428 = 415
