Answer:The answer is x = -203.
Step-by-step explanation:
1. reduce brackets
2. reduce 10 - 523 to -513
3. reduce -513 x -2 to 1026
4. subtract 1026 from both sides
5. reduce 823 - 1026 to -203
(i) Given radius r = 15 cm ∴ diameter d = 2 x 15 = 30 cm Circumference C = πd units = 227227 x 30 = 66076607 = 94.28 cm (ii) Given circumference C = 1760 cm 2πr = 1760 2 x 227227 x r = 1760 r = 1760×72×221760×72×22 = 160×72×2160×72×2 = 40 x 7 = 280 cm Diameter = 2 x r = 2 x 280 = 560 cm (iii) diameter d = 24m radius r = d2d2 = 242242 = 12 m Circumference C = 2 πr units = 2 x 227227 x 12 = 52875287 = 75.4 m Tabulating the results S. No. radius (r) diameter (d) circumference (C) (i) 15 cm 30 cm 94.28 cm (ii) 280 cm 560 cm 1760 cm (iii) 12 m 24
a bit messy sorry for that
Well, the rule of rounding is: if the number is higher than 5, or 5, you round up, and if it is lower than 5, you round down. 5 gets rounded up, so that makes 7 and eight, and eight is higher than 5 so it also gets rounded up, so that would be 6,322. If the decimals were lower, than you would have gotten 6,320, but we rounded up, so 6,322 is the correct answer. Did this help?
Answer:
It's b, 45 degrees
Step-by-step explanation:
