Finding a common denominator between 10 and 12 to be 10*12=120, we can multiply 9/10 by 12/12 and 3/12 by 10/10 to get 108/120 and 30/120 respectively. Dividing the 2 (as we want to know how much 3/12 or 30/120 goes into 9/10 or 108/120), we get
(108/120)/(30/120)=(108/120)*(120/30)=(108/30)=3+18/30 (as 30 goes into 90 3 times and 108-90=18)
Answer:
1) 6
2) 63 15/16
Step-by-step explanation:
1)
= 6^9 / 6^8
= 6^(9-8)
= 6^1
= 6
2)
= 2^6 - 4^5 * 4^-7
= 2^6 - 4^-2
= 2^6 - 1/4^2
= 64 - (1/16)
= (1024 - 1) / 16
= 1023/16
= 63 15/16
Answer:
D = 286°
Step-by-step explanation:
Find both the angles of each right triangle.
Triangle A : 53°, 37°, 90°
180° - 127° = 53°
53° + 90° = 143°
180° - 143° = 37°
Triangle B: 90°, 53°, 37°
180° - 127° = 53°
53° + 90° = 143°
180° - 143° = 37°
Now, we find <em>w.</em>
<em>w</em> = 180° - 37° = 143°
<em>r </em>= 2<em>w</em> = 143 × 2
<em>r</em> = 286°
Answer:
(10, 0)
Step-by-step explanation:
(x2 + x1/2 , y2 + y1/2)
[10 + 10 / 2 , 1 + (-1) / 2]
(20/2 , 0/2)
(10, 0)
