Answer:

The aircraft is gaining altitude at 250\frac{mi}{h}

Explanation:

Draw a vector diagram. (Right angle triangle speed as the hypotenuse)

Let

x -----> horizontal component of the speed

y ----> vertical component of the speed

s ----> speed in miles per hour

we know that

x=cos(30\°)(s)

y=sin(30\°)(s)

we have

s=500\ \frac{mi}{h}

cos(30\°)=\frac{\sqrt{3}}{2}

sin(30\°)=\frac{1}{2}

substitute

x=\frac{\sqrt{3}}{2}(500)

x=250\sqrt{3}\frac{mi}{h}

y=\frac{1}{2}(500)

y=250\frac{mi}{h}

therefore

The aircraft is gaining altitude at 250\frac{mi}{h}

Why do some disaccharides give positive Benedict’s tests while other disaccharides give negative tests?
vodka [1.7K]

Basically, Benedict's test identifies the existence of aldehydes and alpha-hydroxy-ketones, also by hemiacetal, as well as those that take place in specific ketoses. Therefore, it is an alpha-hydroxy-ketone even if the ketose fructose is not strictly a reducing sugar, and provides a positive test since it is transformed into the mannose and aldoses glucose by the base inside the reagent.

If the ratio of students with green shirts to total students in a class is 3 to 8, and are 12 students wearing green shirts, how
jekas [21]

Answer:

20

Explanation:

You would set up a proportion in order to solve this

3 green           12 green

------------     =   ------------

8 total                x total

Then you would cross mulitply for x and get 32. Since that is the total number, you would have to subract the 12 from 32 to get 20.
