Answer:
1/6 + 1/5 = 1/x, 3 days
Step-by-step explanation:
a) x days will take to paint the house together.
b) 1/6 part of the house, Noah paints for 1 day.
1/5 part of the house, Owen paints for 1 day
1/x part of the house they paint for 1 day together, and also we can write that
(1/6 + 1/5) part of the house they paint for 1 day together.
So, we can write equation
1/6 + 1/5 = 1/x
c) 1/6 + 1/5 = 1/x
30x*1/6 + 30x*1/5 = 30x*1/x
5x + 6x = 30
11x = 30
x = 30/11 ≈2.72 ≈ 3 days
Seems like you forgot to attach the table.
For this reason, I will explain how to solve this question and you can apply using the numbers in your table.
We are given that:
y is inversely proportion to x. This means that as y decreases, x increases and vice versa.
Writing this into equation, we would get:
y = c/x where c is the constant of proportionality.
Now, we have the constant of proportionality given as 4.5.
This means that the equation that relates x and y is:
y = (4.5) / x
So, to fill in the table, we would substitute with the given x or y in the equation above and solve for the other variable.
Examples:
If given that x=2, then:
y = (4.5) / (2) = 2.25
If given that y=3, then:
3 = (4.5) / x
x = (4.5) / (3) = 1.5
Hope this helps :)
Answer:
D is a perfect square
Step-by-step explanation:
a perfect square is a squared number that has a square root of an even number like sqrt(64) = 8 and 8 is an even number making it a perfect square
