Answer: a) 6 b) 11.53 c) the smallest number of significant digits is 4
<u>Step-by-step explanation:</u>
a)
Complete the subtraction and addition (you can do this manually by lining up the decimal ... or... using a calculator)
2.784 - 3.00079 + 10.671 + 1.0798 = 11.5340
→ there are 6 digits in the answer
b & c)
2.784 has 4 significant digits
3.00079 has 6 significant digits
10.671 has 5 significant digits
1.0798 has 5 significant digits
→ the smallest number of significant digits is 4 so round the answer from part a to 4 significant digits: ![\large\boxed{11.53}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B11.53%7D)
Answer:
T10 = 1403.
Step-by-step explanation:
8 27 66 131 228
Differences in terms are 19 39 65 97
20 26 32 <-------- increasing by 6
We can extend this to 19 39 65 97 135 179 229 285
20 26 32 38 44 50 56 62
347 415
68
So the 6th term is 228 + 135 = 363.
7th is 363 + 179 = 542
8th term = 542 + 229 = 771
9th term = 771 + 285 = 1056
10th term = 1056 + 347 = 1403.

Answer:
4x+9=x+15
x = 2
Step-by-step explanation:
Let's solve this equation I just made:
4x + 9 = x + 15
Subtract 9 from each side:
4x = x + 6
Subtract x from each side:
3x = 6
Divide each side by 3:
x = 2
