Given :

An airplane cuts through the morning sky for every 1,000 feet that he climbs the outside temperature drops 20° F.

To Find :

The rate of the temperature change in degrees Fahrenheit per foot.

Solution :

Let, rate of the temperature change in degrees Fahrenheit per foot is x.

So,

x = \dfrac{20}{1000}\ ^oF/foot\\\\x = 0.02 ^oF/foot

Therefore, rate of the temperature change in degrees Fahrenheit per foot is 0.02.

Hence, this is the required solution.

Answer:

\dfrac{x}{3}+\dfrac{3}{y}

Step-by-step explanation:

<u>Given fraction</u>:

\dfrac{xy+9}{3y}

\textsf{Apply the fraction rule} \quad \dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}:

\implies \dfrac{xy}{3y}+\dfrac{9}{3y}

Rewrite 9 as 3 · 3:

\implies \dfrac{xy}{3y}+\dfrac{3 \cdot 3}{3y}

Cancel the common factor y in the first fraction and the common factor 3 in the second fraction:

\implies \dfrac{x\diagup\!\!\!\!y}{3\diagup\!\!\!\!y}+\dfrac{\diagup\!\!\!\!3 \cdot 3}{\diagup\!\!\!\!3y}

\implies \dfrac{x}{3}+\dfrac{3}{y}

Answer this one for me thanks ppppp
Brilliant_brown [7]

Answer:

16.6 units

Step-by-step explanation:

Hi there!

We can use the Pythagorean theorem to help us solve this problem: a^2+b^2=c^2 where c is the longest side of a right triangle (the hypotenuse) and a and b are the other two sides

It's safe to assume that x is the longest side in this triangle, making it the c value. Plug 14 and 9 into the equation as a and b and solve for x:

14^2+9^2=x^2\\196+81=x^2\\277=x^2\\x=16.6

Therefore, the value of x is 16.6 units when rounded to the nearest tenth.

I hope this helps!
