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 milliliters of water is in the resulting mixture of hand sanitizers?
Answer:
(370-2x)ml
Step-by-step explanation:
We are given that
In first hand sanitizer
Total solution=200ml
Alcohol=15% of 200ml
Alcohol=[tex]\frac{15}{100}\times 200=30ml[/tex]
In second hand sanitizer
Solution=200 ml
Alcohol=x% of 200 ml
Alcohol=[tex]\frac{x}{100}\times 200=2x ml[/tex]
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

REAL LIFE A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet. Abo
azardous waste can the container hold? Round your answer to the nearest whole number. (1 ft 7.5 gal)
Answer:
It can hold up to [tex]1.256ft^3[/tex] of waste
Step-by-step explanation:
Given
[tex]D = 1.5ft[/tex] -- Diameter
[tex]h = 1.6ft[/tex] -- height
Required
Determine the amount of waste it can hold
This simply means that we calculate the volume of the cylindrical container.
And this is calculated using:
[tex]Volume = \pi r^2h[/tex]
Where
[tex]\pi = 3.14[/tex]
and
[tex]r = \frac{D}{2}[/tex]
[tex]r = \frac{1.5}{2}[/tex]
[tex]r = 0.75[/tex]
So, we have:
[tex]Volume = 3.14 * 0.5^2 * 1.6[/tex]
[tex]Volume = 1.256ft^3[/tex]
Hence, it can hold up to [tex]1.256ft^3[/tex] of waste
The amount of waste a cylinder can hold nearest to the whole number is 3 cubic feet.
What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet.
The amount of waste a cylinder can hold will be given by the volume of the cylinder.
The volume of the cylinder will be
[tex]\rm Volume = \dfrac{\pi}{4} d^2 h[/tex]
We have
d = 1.5 ft
h = 1.6 ft
Then
[tex]\rm Volume = \dfrac{\pi}{4} * 1.5^2 * 1.6\\\\\rm Volume = \dfrac{\pi}{4} *2.25 * 1.6\\\\\rm Volume = 2.82 \approx 3 \ ft^3[/tex]
More about the cylinder link is given below.

A brick has a mass of 18.4kg and a volume of 923cm°. Evaluate the density of the brick in g/cm3 rounded to 3
The density of brick can be obtained for the given case as 197.616 g/cm³.
What is the ratio of two numbers?The ratio of two numbers a and b can be written as a : b = a/b.
The ratio of two quantities is the unit rate of one quantity with respect to the other.
The mass and volume of the brick are 18.4 kg and 923cm³ respectively.
Mass can be converted into gram as 18.4 × 1000 = 18400 g.
Since, the density is given as ratio of mass and volume.
It can be calculated as below,
⇒ 182400 ÷ 923 = 197.616 g/cm³.
Hence, the density of the brick can be obtained as 197.616 g/cm³.

Answer:
14.9 cm
Step-by-step explanation:
To find c using the Law of Sines, you must know angle C. That is found from ...
C = 180° -A -B = 180° -150° -12° = 18°
Then the law of sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B) = (10 cm)·sin(18°)/sin(12°)
c ≈ 14.9 cm

A. -1 4/5
B. -5/9
C. 5/9
D. 1 4/5
Answer:
-1 4/5
Step-by-step explanation:
-2/9x = 2/5
(multiply both equations by 9 and 5)
So
-10x = 18
(divide both equations by -10)
x = - 18/10
Simplify:
x= - 9/5

which relation is a function of x
Answer:The fourth function
Step-by-step explanation:
You can never have repeating x-values. You can have repeating y-values though. Whenever determining whether something is a function, just look at whether it has repeating x-values or not. If it does, it is not a function. If it doesn't, it is a function.
