Answer:
45.8
Step-by-step explanation:
Say the number Malachy was thinking of is <em>x</em>.
Doubling it gives 2x, which we see also equals 91.6. Set these equal to each other:
2x = 91.6
To solve, we divide both sides by 2 and get x = 45.8, which is our answer.
Answer:
C. 2.5 or 5/2
Step-by-step explanation:
The anser is the second box circle thing
3) 3.sec² Ф = 4.tan² Ф
but sec² Ф = 1/cos² Ф
3/cos² Ф = 4.tan² Ф
3/4 = (tan² Ф).(cos² Ф) ; tan² Ф = sin² Ф/cos² Ф
3/4 = (sin² Ф)x(cos² Ф)/(cos² Ф)
sin² Ф = 3/4
a) sin Ф = +(√3)/2 and b) sin Ф = - (√3)/2
sin Ф = + - (√3)/2 → Ф =π/3 + kπ/3
Answer:
0.92
Step-by-step explanation:
The highest rainfall was 1.25
The lowest rainfall was 0.33
