Answer:
Ships A and B are 1,425 feet apart and detect a submarine below them. The angle of depression from ship A to the submarine is 59°, and the angle of depression from ship B to the submarine is 47°.
How far away is the submarine from the two ships? Round to the nearest hundredth of a foot.
The distance from ship A to the submarine is about
feet.
The distance from ship B to the submarine is about
feet.
Step-by-step explanation: answer this and ill answer yours.
For this case we convert the mixed numbers to improper fractions:
Now, we propose a rule of three:
pounds of blueberries ------------->
cups of muffin mix
7 pounds of blueberries -----------------------------> x
Where the variable "x" represents the number of cups of muffin mix that Honey should use.
So approximately Honey should use 
cups of muffin mix
Answer:
Approximately Honey should use cups of muffin mix
Given that the number of bridges has been modeled by the function:
<span>y=149(x+1.5)^2+489,505
To find the year in which, y=505000 we shall proceed as follows:
From:
</span>y=149(x+1.5)^2+489,505
substituting y=505000 we shall have:
505000=149(x+1.5)^2+489,505
simplifying the above we get:
0=149(x+1.5)^2-15495
expanding the above we get:
0=149x^2+447x+335.25-15495
simplifying
0=149x^2+447x-15159.8
solving the quadratic equation by quadratic formula we get:
x~8.69771 or x~-11.6977
hence we take positve number:
x~8.69771~8.7 years~9 years
thus the year in which the number will be 505000 will be:
2000+9=2009
9/6 or the simplified version is 1 1/2
$174,542 times $300 is equal to 52 362 600 U.S. dollars.<span>2</span>
