The amount of water in a bottle is reduced by 85% to 20 milliliters. how much water was originally in the bottle?

To find the original quantity when given the percent it was reduced and the amount left, divide the amount left by the percentage that is left:

The bottle was reduced by 85%, which means there is 15% left left in the bottle ( 100% - 85% = 15%)

Now divide the amount left by the percentage left:

20 / 0.15 = 133.33

The original amount was 133.33 milliliters ( Round answer as needed)

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
