Answer:
28°
Step-by-step explanation:
soln
(x+3)°+(2x+3)°
x°+3°+2x°+3°=90°(beign complementary angles)
3x+6=90°
3x=90°_6
3x=84
x=84/3
x=28°
Answer:
Answer of 17 is ㏒(
+15x), Answer of 33 is x = 8 , Answer of 35 is x = ㏒10/㏒2 , Answer of 37 is x = -㏒12/㏒8 and Answer of 39 is x = 5
Step-by-step explanation:
17. ㏒x + ㏒(x+15)
Using property ㏒a + ㏒b = ㏒a×b
∴ ㏒x + ㏒(x+15)
㏒x×(x+15)
㏒(
+15x)
The answer is ㏒(
+15x)
33. 2^(x-5) = 8
2^(x-5) = 2^3
Using property 2^a = 2^b
Then a = b
∴x-5 = 3
x = 8
The answer is x = 8
35. 2^x = 10
Taking log on both sides gives
㏒2^x = ㏒10
x×㏒2 = ㏒10
x = ㏒10/㏒2
The answer is x = ㏒10/㏒2
37. 8^-x = 12
Taking log on both sides gives
㏒8^-x = ㏒12
-x×㏒8 = ㏒12
x = -㏒12/㏒8
The answer is x = -㏒12/㏒8
39. 5(2^3 × x) = 8
5(8×x) = 8
x = 5
The answer is x=5
Answer:
Students
Step-by-step explanation:
Teachers: 13/20= 0.65 = 65%
Students: 37/50= 0.74 = 74%
74% > 65%
Students are more in favor of the new club than teachers
Answer:
the shaded area is 26, the non-shaded area 16
Step-by-step explanation:
The red shaded lines had numbers as well so I add all of them up.
The non-shaded lines didn't have a number, but the bottom had the same length of the top line so therefore your answer is 26 for Shaded, and 16 for non-shaded.
