If a, b, c is an arithmetic sequence then a + c = 2b
a = 1/10; b = 3/20, c = 5/30
a + c = 1/10 + 5/30 = 3/30 + 5/30 = (3+5)/30 = 8/30
2b = 2 · 3/20 = 3/10 = 9/30
8/30 ≠ 9/30
If a, b, c is a geometric sequence then ac = b²
ac = 1/10 · 5/30 = 1/2 · 1/30 = 1/60
b² = (3/20)² = 9/400
1/60 ≠ 9/400

Hello there,
60 square feet= $287.00 + $80.00
= $367
1 square feet= $367 / 60
= $6.116666667
= $6.12 (to 2dp)
Hope this helps :))

Answer:
1a - reduction
2a- enlargement
3a- reduction
4a- enlargement
Step-by-step explanation:
when the scale factor is greater than 100% it is making it larger, when less than 100% size it is making it smaller. for every answer do the original number (ex #1 would be 48 inches) and multiply it by the scale factor in decimal form, by moving the decimal over two places (ex #1 the 25% would become .25 or 1/4). therefore #1 would be an equation like 48 x 0.25= 12
