Answer:
Step-by-step explanation:
22.5 degrees is half of 45 degrees (special angle for which we know exactly the value of all three basic trigonometric functions (sine, cosine, and tangent).
So we start recalling the formula for tangent of a half angle: 
We need just the values of:
and of
to answer the question. Then, we use those values in the original formula for tangent of a half angle:
Xy + yx+ x - 3x - 3y
xy + yx + -2x + 3y
Since there are 100 squares and 6 aren’t colored in, the answer should be .94. It’s kind of like counting a dollar since 100 pennies = a dollar.
The exact answer in fraction from is 2/15
The approximate answer in decimal form is 0.1333 (rounded to four decimal places)
The decimal value 0.1333 is equivalent to 13.33%
These are three ways to say the same basic answer.
===============================================
Explanation:
We have 4 red cards and 6 blue cards giving 4+6 = 10 total.
The probability of picking not blue (aka picking red) is 4/10 because there are 4 red out of 10 total.
If we don't replace the card we picked, then we have 3 red left over out of 9 total. The probability of picking red again is 3/9
Multiply those fractions
(4/10)*(3/9) = (4*3)/(10*9) = 12/90
Now reduce
12/90 = (6*2)/(6*15) = 2/15
note how the GCF 6 cancels
Using a calculator,
2/15 = 0.1333 approximately
The '3's after the decimal point go on forever.
The answer would be A.
12:32
Highest common factor would be 4, so divide each side by 4.
3:8
Which would be A.
HOPE THIS HELPS YOU! ^_^
