The unit rate is also known as the constant of proportionality, but not as a proportion.
Answer:
of the lasagna is left
<u>Step-by-step explanation:</u>
Given:
Amount of lasagna Rico eats = 1/9
Amount of lasagna His friend eats = 1/18
To Find:
The amount lasagna is left =?
Solution:
Total lasagna ate by both Rico and his friend = Amount of lasagna Rico eats + Amount of lasagna His friend eats
Total lasagna ate by both Rico and his friend = ![\frac{1}{9} + \frac{1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B9%7D%20%2B%20%5Cfrac%7B1%7D%7B18%7D)
Total lasagna ate by both Rico and his friend = ![\frac{2}{19} + \frac{1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B19%7D%20%2B%20%5Cfrac%7B1%7D%7B18%7D)
Total lasagna ate by both Rico and his friend = ![\frac{3}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B18%7D%20)
Total lasagna ate by both Rico and his friend = ![\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%20)
The amount lasagna is left = 1 - Total lasagna ate by both Rico and his friend.
The amount lasagna is left = ![1 - \frac{1}{6}](https://tex.z-dn.net/?f=1%20-%20%5Cfrac%7B1%7D%7B6%7D)
The amount lasagna is left =![\frac{6-1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B6-1%7D%7B6%7D)
The amount lasagna is left =![\frac{5}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B6%7D)

Answer:
![s = 7t](https://tex.z-dn.net/?f=%20s%20%3D%207t%20)
Step-by-step explanation:
The table given shows that both variables are directly proportional to each other. That is, as s variable increases, y variable also increases.
Equation to represent this direct proportion would be:
,
where, k = constant of proportionality.
Let's find k from the table given.
Let's use any pair values of of s and t given in the table. Say, s = 21, t = 3
![s = kt](https://tex.z-dn.net/?f=%20s%20%3D%20kt%20)
![21 = k3](https://tex.z-dn.net/?f=%2021%20%3D%20k3%20)
Divide both sides by 3
![\frac{21}{3} = \frac{k3}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B21%7D%7B3%7D%20%3D%20%5Cfrac%7Bk3%7D%7B3%7D%20)
![7 = k](https://tex.z-dn.net/?f=%207%20%3D%20k%20)
![k = 7](https://tex.z-dn.net/?f=%20k%20%3D%207%20)
Plug in k = 3 into
:
![s = 7t](https://tex.z-dn.net/?f=%20s%20%3D%207t%20)
Answer:
The correct option is option 3
Step-by-step explanation:
Monomials are algebraic expressions that contain one term. It can be variables combined together to make one single term. It can be a single variable combined many times. As long as it is one single entity, it is a monomial
Given the formula for the area of the right angles triangle above to be
A =1/2bh
Where
b = 6x = base of the right angle triangle and
h = 7x = height of the right angle triangle.
The area would be
A = 1/2 × 7x × 6x
A= 42x^2 / 2
A= 21x^2 inches^2
Also written as
21x^2 squared inches
21x^2 is a monomial
