The smallest decimal is 0.019
Answer:
y=140°
Step-by-step explanation:
Method 1.
The exterior angle theorem tells us that y=20+120=140
Method 2.
Solve for x first., then use that to solve for y.
The sum of the interior angles of a triangle is 180, so we can get x by doing 180-20-120=40.
y and x make a straight angle which is 180°, so we can get y by doing 180-40=140
691/1000 is already in its simplest form, for 691 is a prime number and it cannot be reduced by any number other than 1 and 691. (and 1000 is not divisible by 691 also)
691/1000 in its simplest form is 691/100~
Well 9%=0.09 ( NOT 0.9, PEOPLE MAKE THAT MISTAKE ALL THE TIME ), so 112*0.09=10.80
Then:
112-10.8=101.20
$101.20 is the answer.
The ratios of y over x are all equal to 1/3, thus we may infer that: B. the table is proportionate.
What is a Proportional Relationship?
Any pair of values in a table that depicts a proportionate relationship have the same value for the proportionality constant, k, where k = y/x.
Check each pair of values in the table to see if k is the same:
(36.75, 12.25):
k = 12.25/36.75 = 0.33
(16.8, 5.6):
k = 5.6/16.8 = 0.33
(77.1, 25.7):
k = 25.7/77.1 = 0.33
It is proportionate because the ratios of y across x are all equal to 1/3, which implies that the value of k is identical for all values.
