3X+9X=180
12X=180
X=15°
Angle 1=3X
Angle 1 =45°
That's your answer.
Answer:
Of the basketball players on the team, exactly 75% of the players have heights above 180
Step-by-step explanation:
So, they are 12 basketball players in total
1 - 170 - This is 1/12
2 - 175 - This is 1/6
1 - 180 - This is 1/12
4- 185 - This is 1/3
3 - 190 - This is 1/4
1 - 195 - This is 1/12
75% (Or 3/4) have heights above 180
Therefore, the answer is B
We can employ a simple repeated decimal trick:



###
Alternatively, we can compute the partial sum of the series.





As
, the second term vanishes and we're left with
. Notice that this is really just a more formal version of the earlier trick.
Answer:
-212800
Step-by-step explanation:
7.2 × 10³ = 7.2 × 1000 = 7200
2.2 × 10 to the power 5 = 2.2 × 100000 = 220000
7200 - 220000 = -212800
