Answer:
Explanation:
2/7 = 8/28
1/4 = 7/28
The
8+7 = 15 so 15/28 of lawn has been mowed, therefore 13/28 of the lawn is left still to be mowed.
The ozone layer is comprised of ozone, an atom which is constructed of 3 oxygen molecules.
Hope that helped =)
A- Graph B shows exponential growth of a population.
Graph B is a type of exponential equation where y=a(b)^x
"a" is the initial value that intercepts the y-axis in the above equation.
"b" is the value that every value thereafter is growing (multiplying by). Note, if "b" is 1- your value is not growing (since it is staying at it's original 100%). If "b" is, for example 1.5 your value is growing by 50% each time (1 gives you your original 100%, and the .5 gives you an additional 50% on top of that).
"x" is your input, and here it is the exponent because you are multiplying "b" to the power of your input for each value.

I'm actually just guessing
