Susan wants to have 30% of her gumballs be green If there are
Inga [223]

Answer:

15 gumballs

Step-by-step explanation:

There would have to be...

30%*50 green gumballs

We can start by converting 30% to a fraction. Any percentage is just that number over one hundred so...

30/100*50

We can simplify 30/100 by dividing the numerator and the denominator by 10...

3/10*50

Cancel out 10 and 50 (50/10=5)

3*5

15 gumballs would have to be green

An acute angle θ is in a right triangle with sin θ = six sevenths. What is the value of cot θ?
inysia [295]
\sin \theta =\dfrac{6}{7}\\
\cot \theta=\dfrac{x}{6}\\
x^2+6^2=7^2\\
x^2=49-36\\
x^2=13\\
x=\sqrt{13}\\
\boxed{\cot \theta =\dfrac{\sqrt{13}}{6}}

The angle of elevation of the top of a tower from a point 42 metres away from it's base on level ground is 26 degrees. find the
Hatshy [7]

Answer:

20.485 Meters

Step-by-step explanation:

So first you wanna draw a diagram.  Start with the tower, then on the ground to the left (or right) draw a point.  The point will be labeled as 42 m away from the tower.  Now draw a line from that point to the top of the tower.  This makes your triangle, and that angle you just drew that touches the point is 26 degrees.

Now, since you have a right triangle you can use trig.  You know an angle and a side.  Specifically, relative to the 26 degree angle you know the adjacent angle and want the opposite, which is the tower.  So opposite and adjacent is tangent.  So you set up tan(26) = o/42 where o is the opposite side.  

So solving you get o = 20.485 meters
