Kenji sees a plastic bottle that is made using 40% recycled material.the empty bottle weighs 3 ounces.which equation can Kenji use to calculate the amount of recycled material in the bottle,r?
A 3 x 40%=r
B 40%=3 x r
C 40%=3 divide by r
D 3 divide by 40%=r
answer this question pls
You wouldn't normally use a percentage in an equation as used here but if 40% represents .4 you would use 3 * .4 to get 40% of 3.
C and D are both the same and B is .40/3 I would select A.
The equation that Kenji can use to calculate the amount of recycled material in the bottle is:
A) 3 x 40% = r.
The equation that Kenji can use to calculate the amount of recycled material in the bottle, denoted by "r", can be determined by understanding that the weight of the plastic bottle is made up of the weight of the recycled material and the weight of the non-recycled material.
Since the bottle is made using 40% recycled material, it means that 40% of the weight of the bottle is from the recycled material. Therefore, the equation that Kenji can use is:
r = 40% of 3 ounces
To calculate this, we need to convert the percentage to a decimal. Since 40% is equivalent to 0.4, we can rewrite the equation as:
r = 0.4 * 3 ounces
Now, we can simplify the equation to find the value of "r":
r = 1.2 ounces
Thus, the correct equation that Kenji can use to calculate the amount of recycled material in the bottle is:
A) 3 x 40% = r
