Answer: The boat moved 768.51 feet in that time .
Step-by-step explanation:
Since we have given that
Height of the lighthouse = 1000 feet
Angle depression to boat 'a' = 29°
Angle of depression to shore 'b' = 44°
Consider ΔABC,
Now, Consider, ΔABD,
We need to find the distance that the boat moved in that time i.e. BC
so,
Hence, the boat moved 768.51 feet in that time .
Explanation:
Let's say we're buying only 8 dollars of stuff. 8 dollars can only be formed, in this case, by 2 oyster shell grit bags, since they costs 4 dollars each.
Now, we already bought 2 oyster shell grit bags, now we have to buy sunflower seeds. Let's say we're buying only 20 dollars of sunflower seeds. 20 dollars can only be formed, in this case, by 4 sunflower seeds bags since they cost 5 dollars each.
Equation:
x will be the number of oyster shell grit bags and 6 - x will be the number of sunflower seeds bags.
4x + 5(6 - x) = 28 → we combine the price with the corresponding variables.
4x + 30 - 5x = 28
4x - 5x = 28 - 30
-1x = 28 - 30
-1x = -2
x = -2 / -1
x = 2
So, if <em>x = 2</em>, <em>6 - x</em> =<em> 6 - 2</em> which equals 4.
