Answer: 1600batteries
Step-by-step explanation:
Let the number of inspected battery be y
2.5% of y = 40
5/2% of y = 40
Change 5/2% to fraction
5/200 × y = 40
5y/200=40
Cross multiply
5y= 40×200
5y=8000
y=8000÷5
y=1600
The total number of battery inspected is 1600.
Answer:
The answer is B. Sorry I don't know how to do it.
Step-by-step explanation:
The reactangle has an area of x.
So that means two numbers multiplied to each other equal to x. We can just think of itwo numbers that when multiplied equal to x as a and b.
So that means the side lengths are <u />a and b. And ab = x (will be using this right next).
And it was multiplied by some scale factor that made the new area 9x. So if the scale factor is y, then:




y can not equal to -3, because the length of a side of any polygon can never be negative.
So the dilation is 3.And so if the dimension is 5 by 8.
Then the area is

And so then

And then after the dilation, it would be

We could check it another way too. Since we said the scale factor is 3, then:

So
basically
15 by 24 is the new dimensions :)
Answer:then the days would be on the x axis (dependant variable) and the Amount of candy would be on the y axis(independent variable=something that can be changed)
All the equations can be graphed and solved by graphing. They can also be solved using various other methods
