Answer:
6. my bad is it wrong
Step-by-step explanation:
<span>(a.)
Let's say α is the angle that subtends from the top of the screen to horizontal eye-level.
Let β be the angle that subtends from the bottom of the screen to horizontal eye-level.
tanα = (22 + 10 - 4) / x = 28/x
α = arctan(28/x)
tanβ = (10 - 4) / x = 6/x
β = arctan(6/x)
Ɵ = α - β
Ɵ = arctan(28/x) - arctan(6/x)
(b.)
tanƟ = tan(α - β) = (tanα - tanβ) / (1 + tanα tanβ)
tanƟ = (28/x - 6/x) / [1 + (28/x)(6/x)]
tanƟ = (22/x) / [1 + (168/x²)]
tanƟ = 22x / (x² + 168)
Ɵ = arctan[22x / (x² + 168)]</span>
Answer:
$49.50
Step-by-step explanation:
You take the $45 and multiply it by 10% (tax). That comes out to $4.50. Then, you take the $45.00 (grocery bill) and add it to $4.50 (10% tax)
$45.00 + $4.50=$49.50
well, 50% is pretty much half.
you need 2500 for the deposit, you have 50% or half of that.
whatever% of anything is just (whatever/100) * anything.
50% of 2500 is just (50/100) * 2500 or 0.5 * 2500 or 1250.
how much more do you need? well, you need the other 50%.
50% of 2500 is just (50/100) * 2500 or 0.5 * 2500 or 1250.
3.264 x 10^1 hope this helps :)
