10. Perimeter = 56 ft  ;  Area = 195 sq. ft.

11. If my math is correct, Perimeter = 76 km  ;  Area = 706 sq. km

12. Circumference = 100 cm  ;  Area = 2500 sq. cm

13. Circumference = 24 ft.  ;  Area = 144 sq. ft.

14. Perimeter = 62 ft.  ;  Area = 238 sq. ft.

15. Circumference = 22 yd.  ;  Area = 121 sq. yd.

16. Perimeter = 40 mm  ;  Area = 100 sq mm

Step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
