The answer is C
If you divide 8 by 200 it becomes 0.04 which is 4/100 in fraction form. If you simplify it then become 1/25.
To find the range of data, you first order the data least to greatest:
7, 12, 15
Then you subtract the smallest number from the largest:
15-7=8
The range is 8.
Answer: B and C
Step-by-step explanation: For A, vertical angles can be complimentary or supplementary. For D, vertical angles can sometimes be acute but not always.
22 unit cubes and 2 smaller cubes of volume cubic inch each
1/3x+y=10/8
Times 1/2 for both side
1/6x+1/2y=5/8
-
1/6x+1/5y=13/6
=
3/10y=-1/2
Divided 3/10 for both side
y=-5/3
1/3x+y=10/8
1/3x-5/3=10/8
1/3x=70/24
1/3x=35/12
x=35/4
x=8 3/4. As a result, the solution set is (8 3/4,-5/3). Hope it help!
