Hello!
your answer is 170°
supplementary angles always add up to 180°
180° - 10°° = 170°
I hope this helps, and have a nice day!
If your trying to find the slope the first one is
3 and the second one is
4 hoped this helps
The IQR of the data set is choice C: 9.
To find the IQR, you have to first put the numbers in order.
The order is: 10 12 15 17 19 21 23
The IQR is the difference between the first quartile and the third quartile.
Those values are 12 and 21.
21 - 12 = 9
Answer:
1. .........................................
- 2x = 3
- x = 3/2 Fraction
- x = 1.5 Decimal
2. ..........................................
- 5y = 3
- y = 3/5 Fraction
- y = 0.6 Decimal
3. ..........................................
- 0.3z = 0.009
- z = 0.009/0.3 = 9/300 = 3/100 Fraction
- z = 0.09 Decimal
99.99 - 64.25= 35.74
35.74/64.25= 0.556=55.6% or 56% rounded
