So to get this, you just divide 28 by 7 because when you are funding a fraction of. number and the numerator of that fraction is 1, you divide the original number by the denominator.
28 ÷ 7 = 4
Hope this helps!
There are a few options we can take. One way is to use the tangent ratio to tie together the opposite and adjacent sides, and then apply the inverse tangent (aka arctangent) to get the angle itself.
Let x be the upper left acute angle, and y be the lower right acute angle.
We can say
tan(angle) = opposite/adjacent
tan(x) = 16/5
x = arctan(16/5)
x = 72.645975 approximately
x = 72.6
and also
tan(angle) = opposite/adjacent
tan(y) = 5/16
y = arctan(5/16)
y = 17.3540246
y = 17.4
Note how x+y = 72.6+17.4 = 90. The two acute angles of any right triangle are complementary, meaning they always add to 90. So if you found x, then you can compute y = 90-x without needing the tangent ratio.
Your calculator needs to be in degree mode when using the arctangent function, which is denoted as on many graphing calculators.

Step-by-step explanation:
When you reflect across the y axis the numbers stay the same but the x coordinates become negative.
So the new coordinates are:
F(-4, 6)
G (-9, 6)
H (-7, 1)
I (-4, 0)
J (-1, 3)
I believe the answer is C: how close a measurement comes to the expected value
Answer:
1/22
Step-by-step explanation:
- 12 total marbles
- 5/12 - 1/1 = 4/11
- 4/11 - 1/1 = 3/10
- 5/12 × 4/11 × 3/10 = 1/22
