Answer:
- y=0.8x
- See Explanation for others
Step-by-step explanation:
The 3 cans of beans had a total weight of 2.4 Pounds
Therefore:
- 1 can of beans = (2.4 ÷ 3) =0.8 Pounds
The following applies from the options.
- y=0.8x where y is the weight and x is the number of cans.
- A 2-column table with 3 rows. Column 1 is labeled number of cans with entries 5, 15, 20. Column 2 is labeled total weight (in pounds) with entries 4, 12, 16.
Using y=0.8x
When x=5, y=0.8 X 5=4
When x=15, y=0.8 X 15=12
When x=20, y=0.8 X 20=16

- On a coordinate plane, the x-axis is labeled number of cans and the y-axis is labeled total weight (in pounds. A line goes through points (5, 4) and (15, 12). This can be clearly seen from the table above as (5,4) and (15,12) are points on the line.
Given:
Each big square represents one whole.
To find:
The percent represented by the shaded area.
Solution:
One big square have 100 small square.
Shaded part of first big square = 100
Fraction of shaded part of first big square = ![\frac{100}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B100%7D%7B100%7D)
Shaded part of second big square = 19
Fraction of shaded part of second big square = ![\frac{19}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B100%7D)
Fraction of total shaded area:
![$=\frac{100}{100}+\frac{19}{100}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B100%7D%7B100%7D%2B%5Cfrac%7B19%7D%7B100%7D)
![$=\frac{100+19}{100}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B100%2B19%7D%7B100%7D)
![$=\frac{119}{100}](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B119%7D%7B100%7D)
Percent of shaded area:
![$=\frac{119}{100}\times 100\%](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B119%7D%7B100%7D%5Ctimes%20100%5C%25)
= 119%
The shaded area is 119%.
Answer:
x = 36, y = 54.
Step-by-step explanation:
So if x = 36 and y = ?,
Its the same as x = 12, and y = 18.
36 / 12 = 3
That means y / 18 = 3.
Lets reverse this and make it a multiplication problem.
18 x 3 = y.
18 x 3 = 54.
So if x = 36, y = 54.
