Answer:
(-1,-1)(4,-20)(2,0)
Step-by-step explanation: Just fill in the x and y
That would be 36 + -53 = -17 is -53
1) In a proportion: y/x=k
k is your constant of proportionality.
x is your independent variable and y is your dependent variable.
Since you need 3 oz of flour for each 2 oz of sugar, y=3 and x=2.
So k=1.5 (3/2)
3)
a) y/x as a showed above. This question is very similar to #1.
b) y/x=k
Answer:
Rational
Step-by-step explanation:
![\sqrt[3]{125}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B125%7D)
is also equivalent to 5
The definition of a <em>rational </em>number is any whole number, fraction, or decimal that ends or repeats, while an <em>irrational </em>number is any number that cannot be turned into a fraction.
5 is a whole number, and therefore, is a rational number.
First, subtract 90° from 180°, since 180<span>° is the sum of all the angles in a triangle.
180 - 90 = 90</span><span>°.
Now, we can really just test out different sets of numbers in a 2:7 ratio until we find two that have a sum of 90</span><span>°.
If you look closely, 2 + 7 is 9. So, using that logic, multiplying 2:7 by 10 would get you 20</span>° and 70°, which have a sum of 90<span>°.
So the measures of the missing 2 angles is 20</span>° and 70<span>°.
