The half life of a chemical element substance is 16 days, How long will it takes for the substance to decay from 120mg to 2 mg
Answer:
94.5 days
Step-by-step explanation:
We are asked to calculate the time.
The formula to calculate the time for half life =
t = t½ × In (Nt/No)/-In2
t½ = half life = 16 days
No = Initial substance = 120mg
Nt = Amount of substances after time t = 2 mg
t = 16 × In (2/120)/-In2
t = 94.510249529736 days
Approximately = 94.5 days
Therefore, the time it would take for the substance to decay from 120mg to 2 mg is 94.5 days.

The graphs below have the same shape. What is the equation of the blue graph?
================================================================
Explanation:
If we were to keep the red curve completely fixed, but we moved the xy axis four units to the left, then this would give the illusion the red curve is moving four units to the right to arrive at the blue curve's location.
Shifting the xy axis four units to the left is the same as subtracting 4 from each initial input x value. So we go from x to x-4.
The parent function f(x) = x^2 then becomes g(x) = (x-4)^2 which is choice C.
As one way to check, plug in x = 4 and you should find that g(4) = 0. This is the x intercept of the blue curve. Something like g(x) = (x+4)^2 does not work because plugging x = 4 into this leads to g(x) = 64, so that rules out choice A. You can eliminate choices B and D for similar reasoning as well.
Answer:
C.) G(x) = ( x-4 )^2

The length of a right rectangular prism is 3.4 cm. The width of the prism is 1.2 cm. The volume of the prism is 11.016 cubic cm. What is the height of the prism? (Hint: V = L x W x H)
Answer:
sorry i dont know.
Step-by-step explanation:
Answer:
2.7cm
Step-by-step explanation:
11.016cm^3 = 3.4 x 1.2 x H
3.4x1.2=4.08
11.016/4.08 = 2.7
11.016cm^3 = 3.4 x 1.2 x 2.7
solve for x by using the elimination method
Answer:
x=4
Step-by-step explanation:
the ones on top of each other you are adding together so -10x + -2x equals -12x and -32+-16 equals -48 and -48 divided by -12x equals positive 4
Answer:
Step-by-step explanation:
you can see from the picture that adding 2y and -2y cancels out. So the remaining parts of the equations are
-10x=-32
-2x=-16
add the two together:
-12x=-48
x=4

Monica and Brianne each draw one prize ticket at random from different boxes. Monica has a 20% chance of winning a prize. Brianne has a 1/10 chance of winning a prize. Is Monica or Brianne more likely to win a prize? Explain your reasoning.
Answer: Monica
Step-by-step explanation:
Given
Monica has a 20% chance of winning a prize
Brianne has a [tex]\frac{1}{10}[/tex] chance of winning a prize
20% chance refers to
[tex]\dfrac{20}{100}=\dfrac{2}{10}[/tex]
As
[tex]\dfrac{2}{10}>\dfrac{1}{10}[/tex]
therefore, monica is more likely to win the prize.
Si el impuesto sobre ventas de un DVD, de $16.000 es $1.40, ¿ a cuanto ascendería el impuesto sobre ventas de un reproductor Blue-ray de $120.00?
Answer:
Impuesto= $10.5
Step-by-step explanation:
Dada la siguiente información:
El impuesto sobre ventas de un DVD, de $16.000 es $1.40.
Primero, debemos determinar la tasa porcentual del impiesto:
Tasa impositiva= 1.4/16= 0.0875 = 8.75%
Ahora, el impuesto sobre $120:
Impuesto= 120*0.0875
Impuesto= $10.5

Answer:
18
Step-by-step explanation:
Intersecting Secants Theorem:
6(x + 6) = 8(8 + 10)
6x + 36 = 8(18)
6x + 36 = 144
6x = 144 - 36
6x = 108
x = 18

Nina can type 128 words in 4 minutes. At this rate, how many words can Nina type in an hour.
Answer:
1,920 words
Step-by-step explanation:
60 divided by 4 is 15
15 times 128 is 1,920.
Hope it helps! :)
Answer:
1920
Step-by-step explanation:
We know that it takes her 4 minutes to type 128 words
So we need to figure out how many it takes her to type a word per minute
128 divided by 4=32
So multiply 32 word by 60 ( 60 mins = an hour)
Answer=1920
In the equation (x+2)2+(y-3)2=4, the diameter of the circle is...
16
4
3
2
Answer:
4
Step-by-step explanation:
The given equation of circle is:
[tex] (x+2)^2 +(y-3)^2 =4 [/tex]
[tex] (x+2)^2 +(y-3)^2 =2^2 [/tex]
Equating it with:
[tex] (x-h)^2 +(y-k)^2 =r^2 [/tex]
We find:
[tex] r^2=2^2 [/tex]
[tex]\therefore r=2 [/tex]
Radius of the circle = 2 units
Therefore,
Diameter of the circle = 2*2= 4 units

Answer:
x > 9.
Step-by-step explanation:
Here it is just simplifying the inequality.
6 - 2/3x < x - 9
Add 2/3x to both sides.
6 < 5/3x - 9
Add 9 to both sides.
15 < 5/3x
Multiply by 3/5.
9 < x
Flip it.
x > 9.
Answer:
x > 9
