Answer:
9. 2a + 14
10. 7h - 70
Step-by-step explanation:
(2 x a ) + ( 2 x 7 )
(7 x h ) - ( 7 - 10 )
Answer:
70 degrees
Step-by-step explanation:
Angles 130 degrees and TUV are supplementary angles. Thus, the latter is (180 - 120), or 60, degrees. Now the sum of all three interior angles of this triangle must be 180 degrees: (60 + 50 + >TUV) = 180, so >TUV is 70 degrees (answer C).
Answer: a) 300000 b) 200 c) 20000
Step-by-step explanation:
Round so that there is only 1 sig. fig. in the answer
a) 300000 (rounded up to 300,000 not 280,000 as there would be 2 sig figs, 2 and 8)
b) 200 (rounded down)
c) 20000 (rounded up to 20,000 not 18,000 as there would be 2 sig figs, 1 and 8)
The trailing zeroes do not count as sig. figs. so the above answers all have only one sig. fig.
