(370-2x)ml

Step-by-step explanation:

We are given that

In first hand sanitizer

Total solution=200ml

Alcohol=15% of 200ml

Alcohol=Mary has 200ml of hand sanitizer that is 15%, №17887844, 29.01.2023 22:13

In second hand sanitizer

Solution=200 ml

Alcohol=x% of 200 ml

Alcohol=Mary has 200ml of hand sanitizer that is 15%, №17887844, 29.01.2023 22:13

We have to find the water in the resulting mixture of hand sanitizers.

Total solution of two hand sanitizers=200+200=400ml

Total alcohol in two hand sanitizers=(30+2x)ml

Water in two hand sanitizers=400-(30+2x) ml

Water in two hand sanitizers=400-30-2x ml

Water in two hand sanitizers=(370-2x)ml

Hence, water  in the resulting mixture of hand sanitizers=(370-2x)ml

(370-2x)ml

Step-by-step explanation:

We are given that

In first hand sanitizer

Total solution=200ml

Alcohol=15% of 200ml

Alcohol=\frac{15}{100}\times 200=30ml

In second hand sanitizer

Solution=200 ml

Alcohol=x% of 200 ml

Alcohol=\frac{x}{100}\times 200=2x ml

We have to find the water in the resulting mixture of hand sanitizers.

Total solution of two hand sanitizers=200+200=400ml

Total alcohol in two hand sanitizers=(30+2x)ml

Water in two hand sanitizers=400-(30+2x) ml

Water in two hand sanitizers=400-30-2x ml

Water in two hand sanitizers=(370-2x)ml

Hence, water  in the resulting mixture of hand sanitizers=(370-2x)ml

2x

Step-by-step explanation:

ok so basically..

x/100 * 200

200x/100

then you cross out the zeros and you get 2x.

Hope this Helped!! XD

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg
