mary has 200ml of hand sanitizer that is 15% alcohol she mixes it with 200ml of a hand sanitizer that is x% alcohol how many ml is in the first hand sanitizer?

30ml

Step-by-step explanation:

200ml * 15%

200ml * 0.15

= 30

There are 30 ml in the 1st hand sanitizer

30 m l

Step-by-step explanation:

15%=0.15

200 divided by 0.15 is 30.

So therefore,

the answer is 30 ml.

answer: 91

step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
