<span>The difference of a number times 4 and 9 equals 5.  Let the number be n.
Then  4n - 9 = a number times 4
 The difference of a number times 4   AND     9  equals     5 comes out to be:

                                                      4n - 9 = 5

Add 9 to both sides:                       4n       = 14.  Then n = 14/4 = 7/2 (answer)

Note that 14 less 9 is 5.  This is one way in which you can check this result.

A plane is approaching an aircraft carrier at 25° angle of elevation from 3.2 miles away how far above sea level is the plane
s2008m [1.1K]

Answer:

Height\approx 1.35\ miles

Step-by-step explanation:

The angle of elevation=25\textdegree

It is 3.2\ miles away from the point.

If we imagine a right  triangle having an angle 25\textdegree.

Hypotenuse=3.2, Opposite=Height from sea level(h)

\sin 25=\frac{opposite}{hypotenuse}\\\\\sin 25=\frac{h}{3.2}\\\\h=3.2\times \sin 25\\\\h=3.2\times 0.4226\\\\h=1.3524\approx 1.35\ miles

I will give brainliest to the first person who answers.
nasty-shy [4]

Answer:

the answer is \sqrt{5\\} , and - \sqrt{5\\} which is C.

Step-by-step explanation:

well I got that answer by doing this

we have x^{2}= 5

For x^{2}= f (a) the solutions are x = \sqrt{f(a)\\} , - \sqrt{f(a)\\}

so in this case the solutions are \sqrt{5\\}, and - \sqrt{5\\}

HOPE THIS HELPS :)
