Vladimir [108]

Answer: 11378.58 ft


Step-by-step explanation:

1. Draw  a figure like the one attached, where A is the position of the airplane and B and C are the positions of the cars.

2. The distance between the cars is the length BC, then, you need to calculate the measure of BD and DC to add them and obtain BC.

<h2> 3. You know the opposite side and the angles of depression, then, you can calculate the distance between the cars as following:</h2>

BC=BD+DC\\BC=\frac{5150}{tan(35)}+\frac{5150}{tan(52)}\\BC=11378.58ft

What the answer to this equation X/8+4=5 ?
V125BC [204]

Answer:

The answer to this equation is 8

Step-by-step explanation:

\frac{x}{8} +4=5\\

<u>First: Subtract</u>

8-4=4

5 > 4 meaning that 5 is greater than 4.

You still need another number to make it equal than or greater than or equal to five.

5-4=1

Since 5 minus 4 does equal 1

You need somewhere to divide it from to get 1 so you can add up the 4 to it and get the answer to the equation.

<u>Lastly: Divide</u>

\frac{8}{8} =1

1+4=5\\5=5\\4\neq 5

Now, if you do 8/8 which equals 1, 1+4 = 5; Now everything is, <u>equaled</u> up!

<u>So in conclusion...</u>

\frac{x}{8} +4=5\\x=8\\\frac{8}{8}=1\\1+4=5\\5\neq5

Verdich [7]

Split the second term in 9s^2 - 36s + 35 into two terms

Factor out common terms in the first two terms, then in the last two terms

3s(3s - 5) - 7(3s - 5)

Factor out the common term 3s - 5
