You get $35.10 off of the total. So subtract 35.1 from 234 and get 198.9
Answer:
distance of diver 1 from the shark ≈ 18.88 m
Step-by-step explanation:
The illustration forms a triangle. The base of the triangle which is their distance apart is given as 30 m . The known angle of the triangle are 52° and 39°. To find the unknown side we subtract the sum of 52° and 39° from 180°. Note that the total angle in a triangle is 180°.
Therefore,
180 - (52 + 39) = 180 - 91 = 89
°. Now the three angle of the triangles are 52°, 39° and 89°.
Using the law of sine we can find the distance of the diver 1 from the shark.
let a = distance of the first diver to the shark.
a/sin 39° = 30/sin 89°
cross multiply
a sin 89° = 30 sin 39°
divide both sides by sin 89°
a = 30 sin 39°/sin 89°
a = 30 × 0.62932039105
/sin 89°
a = 18.8796117315
/0.99984769515
a = 18.8824876258
a ≈ 18.88 m
Answer:
The total cost will be $60 dollars.
Step-by-step explanation:
If the adults tickets are $20 and the children's are 50% less
$20 × 0.5 = $10
so with two adults and two kids
20 + 20 + 10 + 10 = $60
Answer:
Step-by-step explanation:
= 7-w
( )^2 = (7-w)^2
g = (7-w)^2
Answer:
<em>h</em> = 435.779 m
Step-by-step explanation:
Step 1: Define variables
∅ = 5°
Hypotenuse (the road) = 5000 meters
We need to find height (or the vertical leg on the triangle) = <em>h</em>
Step 2: Use trig
sin∅ = opposite over hypotenuse
sin5° = <em>h</em>/5000
Step 3: Evaluate
5000sin5° = <em>h</em>
<em>h</em> = 435.779 m
