Now, we do multiplication and division from left to right
(9x9) + 8 - (8/10)
=
81 + 8 - 0.8
Now, we do addition and subtraction from left to right
(81 + 8) - 0.8
89 - 0.8
=
88.2
Applying the trigonometry ratios, the missing lengths for right triangle ABC are: 12 and 8√3.
<h3>What is Trigonometry Ratios?</h3>
Trigonometric ratios are defined as the values of all trigonometric functions based on the right-angled triangle's side ratio. The trigonometric ratios of any acute angle in a right-angled triangle are the ratios of its sides to that angle.
<h3>According to the given information:</h3>
Reference angle (∅) = 60
Adjacent = 4√3
Opposite = ?
<h3>Apply TOA:</h3>
tan 60 = opp/adj
tan 60 = Opp/4√3
√3 = opp/4√3
Opposite = √3 × 4√3
Opposite = 12
<h3>Find the other missing side:</h3>
Reference angle (∅) = 60
Adjacent = 4√3
Hypotenuse = ?
<h3>Apply CAH:</h3>
cos 60 = adj/hyp
cos 60 = 4√3/hyp
hyp = 4√3/cos 60
hyp = 4√3/1/2
hyp = 4√3 × 2
hyp = 8√3
Therefore, applying the trigonometry ratios, the missing lengths for right triangle ABC are: 12 and 8√3.

Answer:
1500 people
Step-by-step explanation:
Since 40% are HIV positive (that's a lot of people), 60% will be HIV negative. All you have to do is find 60% of 2500.
60% of 2500 = 0.6 * 2500 = 6 * 250 = 1500
Hope this helps!
3x+6=3x+6 I think that is how you do it but I’m really bad at math
A=p (1+r)^t
300=140 (1+0.06)^t
Solve for t
T=log(300÷140)÷log(1.06)
t=13 months
