Answer:

Answer would be:

1ft/12in and 60sec/1min

Step-by-step explanation:

First think of the units that you are converting separately:

inches → feet

seconds → minute

So you need to find the units that match those.

Now let's look at the units as a whole:

\dfrac{inches}{second}\:\rightarrow\dfrac{feet}{minute}

Now the trick in converting is whatever you are trying to cancel out, you put the factor on top. Since you want to cancel out seconds, you will need to make sure that the conversion factor you will has seconds on top.

For the inches to feet, since inches is what you need to cancel out, then use the conversion factor that has inches in the bottom.

If the measures of five interior angles of a hexagon are 133 , 111 , 92 , 153 , and 109 , what is the measure of the other inter
Burka [1]
The sum of the interior angles of a hexagon is equal

6\cdot\left(180^o-\dfrac{360^o}{6}\right)=6\cdot(180^o-60^o)=6\cdot120^o=720^o

Calculatle the measure of the other interior angle:

720^o-(133^o+111^o+92^o+153^o+109^o)=720^o-598^o=122^o

Answer: 122°

The sum of two numbers is 32. Their difference is 30. What are the two numbers? Show all work
DiKsa [7]

Answer:

a=30 , b = 0

Step-by-step explanation:

let the two numbers be represented as a and b

a + b = 30... eqn 1

a - b = 30 ...... eqn 2

we then add the two equations to get values for a and b

a + b + a - b = 30 + 30

a + b + a -b = 60

2a = 60  ( diivide both sides by 2)

a = 30

we then put value for a = 30 into  any of the equations to get b

a + b = 30,    30 + b= 30

b = 30 -30   , b = 0

to confirm if the answers are correct, we insert the values for a and b in the two equations.

a + b = 30..... eqn 1,      30 + 0 = 30

a - b = 30 ...... eqn 2   ,    30 - 0  = 30

Special right triangles quick check help please! can someone check if these answers are right?
frutty [35]
We have that cos30=\frac{7\sqrt{3}}{w} = \frac{\sqrt{3}}{2} by the definition of cos as the ratio of adjacent leg over the hypotenuse.  Hence, 7/w=1/2 by eradicating square roots. Solving for w in this equation we get that w=7*2=14.
We have that the 3 sides obey the Pythagoran theorem, because:(7\sqrt{3})^2+21^2=(14\sqrt{3})^2 because 488=147+441
Hence, the triangle is right. We also have that one side is half the hypotenuse hence one of the other angles of the triangle is 30 degrees because sin30=1/2. Finally, the third angle is 60 degrees because sum of angles=180.
Here, we have that sin 45=p/44=\frac{\sqrt2}{2}. Multiplying by 44, we have that p=22\sqrt{2}
