Answer:

329.5

Step-by-step explanation:

From the table we see that the common difference d = 0.5 - (-6.5)

= 7, and 7.5 - 0.5 = 7. Also 14.5 - 7.5 = 7.

The first term a1 = -6.5.

The nth term = a1 + (n - 1)d so for our sequence we have:

49th term = -6.5 + (49 - 1)7

= -6.5 + 48 * 7

= -6.5 + 336

= 329.5 (answer).

PLZ HELP 10 PTS!!

Answer:

Jill's best friend jumped 8/21 feet further than Jill.

Step-by-step explanation:

we have that

Jill jumped 6 1/3 feet

Jill best friend jumped 6 5/7 feet

To find out how much farther did Jill's best friend jumped, subtract the length that Jill jumped from the length that Jill best friend jumped

$6\frac{5}{7}-6\frac{1}{3}$

but first convert mixed number to improper fraction

$6\frac{5}{7}\ ft=\frac{6*7+5}{7}=\frac{47}{7}\ ft$

$6\frac{1}{3}\ ft=\frac{6*3+1}{3}=\frac{19}{3}\ ft$

substitute the values

$\frac{47}{7}-\frac{19}{3}=\frac{47*3-7*19}{21}=\frac{8}{21}\ ft$

therefore

Jill's best friend jumped 8/21 feet further than Jill.
