Mr. Avogadro started with 5.14x1022 atoms of Pa-234. Ten days later Mr. Avogadro calculated the original sample had only 6.43 X 1021 atoms of Pa-234. What s the half life of Pa-234?
Answer:
The half life of Pa-234 is approximately 0.0701656609 days
Step-by-step explanation:
The formula for half life is calculated as:
t½ = t.In(2)/In(No/Nt)
Where:
t½ = Half life of the substance in days
t = Time elapsed in days
No = Beginning amount
Nt = End Amount
In the question,
t = Time elapsed = 10 days
No = Beginning amount = 5.14 × 10²²
Nt = End Amount = 6.43 × 10²¹
t½ = t.In(2)/In(No/Nt)
t½ = 10.In(2)/In(5.14 × 10²²/6.43 × 10²¹)
t½ = 6.9314718056/98.78723754
t½ = 0.0701656609 days
The half life of Pa-234 is approximately 0.0701656609 days

A factory can work its employees no more than 5 days a week, and no less than 2 days per
week. Create an inequality to represent the range of days an employee can work. Solve the
inequality to determine the range in hours. Show all of your work and explain each of your
steps. Explain your answer.
Answer: 2 <= X <= 5
Step-by-step explanation:
Answer: 2 <= X <= 5
Step-by-step explanation:
Given that a factory can work its employees no more than 5 days a week, that is, less than or equal to 5 days.
And no less than 2 days per week. That is, greater than or equal to 2 days.
Let X be the number of days employee can work. Then, according to the first statement, X <= 5 and according to the second statement, X >= 2
An inequality to represent the range of days an employee can work will be
2 <= X <= 5
Therefore, an employee can work for 2 days, 3 days, 4 days and 5 days

Which form of a quadratic function is easiest to use when finding the maximum or minimum value of the function?
Answer:
ax² + bx + c
Step-by-step explanation:
The form of a quadratic equation that is easy to use when finding the maximum or minimum value of the function is ax² + bx + c.
Suppose a quadratic function:
f(x) = 2x² - 8x + 9
Use ( -b/2a , f(-b/2a) ).
-b/2a
a = 2
b = -8
-(-8)/2(2)
8/4
= 2
f(2) = 2(2)² - 8(2) + 9
f(2) = 2(4) - 8(2) + 9
f(2) = 8 - 16 + 9
f(2) = 1
The minimum value of this quadratic function is (2, 1).
It represents a minimum value because a > 0.
Answer:
Vertex form
Step-by-step explanation:
There are several forms of the quadratic equation
Standard form: y = ax^2 + bx + c which is useful for the quadratic equation and the axis of symmetry
Factored form: y = (ax - c)(bx - d) which will give us the zeros
and
Vertex form: y = a(x - h)2 + k where ( h,k) is the vertex
The maximum and minimum would be the value of k
It would be maximum when a >0 and minimum when a<0
HELP ME ! Lines l and m are parallel.
Parallel lines l and m are cut by transversals s and t. Clockwise from top left, the angles formed by s, t, and l are blank, 85 degrees, (2 x) degrees, (x minus 10) degrees, 1, blank; formed by s and m are blank, 2, blank, blank; formed by t and m are 3, blank, blank, blank.
What is the measure of angle 3?
25 degrees
35 degrees
70 degrees
85 degrees
Answer:
The correct option is A
A) 25 degrees
Step-by-step explanation:
As two parallel line l and m are cut by the line t, the angles formed (x-10)° and < 3 are alternate angles, therefore they are equal to each other.
< 3 = (x-10)° ⇒ Equation (i)
We know that any straight line has a sum of angles equal to 180°.
Consider line t, it is divided into 3 angles due to cutting. Those angles are 85°, (2x)° and (x-10)°. The sum of these angles is 180° as stated before.
85° + (2x)° + (x-10)° = 180°
Find the value of x:
85 +2x + x - 10 = 180
3x + 75 = 180
3x = 105
x = 35°
Substitute it in Equation (i) to get the value of <3
< 3 = (35 - x)°
< 3 = (35 - 10)°
< 3 = 25°

Answer:
centre = (-5, -4)
radius = 7.42
Step-by-step explanation:
The general form for center-radius is
(x - h)² + (y - k)²= r²
Center = (h, k)
Radius = r
Rearrange the equation.
(x² + 10x) + (y² + 8y) - 14 = 0
Add 14 on both sides.
(x² + 10x) + (y² + 8y) = 14
(10/2)² = 25
(8/2)² = 16
Add 25 and 16 to both sides.
(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16
Factor left side of the equation.
(x+5)² + (x+4)² = 55
(55) = (7.416198)²
(x+5)² + (x+4)² = 7.42²
The radius is 7.42.
The centre is at (-5, -4).

given a standard deck of 52 cards what is the probability of drawing a face card of any suit or a red 6 a 4/13 b 1/4 c 3/13 d 7/26
Answer:
Choice D 7/26
Step-by-step explanation:
So first let's count how many face cards there are. We have a Jack, a Queen, and a King in all of the 4 sets of cards. This knowledge tells us that we have 12 face cards out of the 52 cards. Then, we have 2 red sixes in the game. These come from the 6 of hearts and the 6 of diamonds. This makes the new total of the cards we want to draw 12+2=14. Then we now have the fraction 14/52. After simplifying we get the answer 7/26 is our probability (choice D)
Answer:
7/26
Step-by-step explanation:
52 cards
Jacks , queens, kings are face cards =
3 per suit *4 suits = 12 cards
2 red sixes = 2
P (red 6 or face cards ) = red 6 or face cards / total
= (12+2) / 52
= 14/52
= 7/26

Answer:
[tex]Probability = \frac{6}{29}[/tex]
Step-by-step explanation:
Given
------------------------------Has a brother | Does not have a brother
Has a sister --------------------------- 6 ----------------- 8
Does not have a sister -----------2 ------------------ 13
Required
Probability of having a sister and a brother
First, the total number of students has to be calculated;
Total = 6 + 2+ 8 + 13
Total = 29
Number of students that have a sister and a brother is represented with data in row 1 and column 1 i.e. 6
At this point, the probability can then be calculated;
Probability = Number of students that have a sister and a brother divided by Total number of students
[tex]Probability = \frac{6}{29}[/tex]

Is 15/3=v/7 a true proporation?
Answer:
15/3 = v/7 can be a true proportion.
Step-by-step explanation:
v is a variable, which means that technically any number can be put inside.
In this case, however, when you are solving for v, the numerator must be proportional to the denominator.
In the case of the question, the questioner multiplied ~2.33 to the denominator. Do the same to the numerator:
15 x 2.33 = ~34.95
If the variable v is ~34.95, then it is a true proportion.

Step-by-step explanation:
The area of a circle is
A = pi r^2
A = pi (15)^2
A = 225 pi cm^2
Using 3.14 for pi
A =706.5 cm^2
Using the pi button for pi
A =706.8583471 cm^2
Answer:
225π cm^2, 706.5 cm^2, 706.858... cm^2
Step-by-step explanation:
The area of a circle can be found using the following equation:
[tex]a=\pi r^2[/tex]
We know the radius is 15 cm, so we can substitute 15 cm in for r.
[tex]a=\pi (15cm)^2[/tex]
1. In terms of pi
To find the area in terms of pi, evaluate everything possible without multiplying by pi.
Evaluate the exponent.
[tex]a=\pi (15cm)^2[/tex]
15cm^2= 15 cm * 15 cm = 225 cm^2
[tex]a=\pi * 225 cm^2[/tex]
This can be rewritten as:
[tex]a=225\pi cm^2[/tex]
2. Using 3.14 for pi
Substitute 3.14 in for pi.
[tex]a=\pi (15cm)^2[/tex]
[tex]a=3.14*(15cm)^2[/tex]
[tex]a=3.14*225 cm^2[/tex]
Multiply
[tex]a=706.5 cm^2[/tex]
3. Using 3.14159265.... as pi
[tex]a=\pi (15cm)^2[/tex]
[tex]a=\pi *225 cm^2[/tex]
Multiply, using the pi button on a calculator
[tex]a=706.858346 cm^2[/tex]

what is the value of r?
NIH
Hey there! :)
Answer:
r = 105.
Step-by-step explanation:
In the quadratic formula, √r = [tex]{\sqrt{b^{2}-4ac }[/tex]
Where a = 1, b = -9, and c = -6. Therefore:
√r = √(-9)² - 4(1)(-6)
√r = √81 -4(-6)
√r = √81 + 24
√r = √105
Therefore, r = 105.

BRAINLIEST!!!! Suppose 40 bikes stand near a playground. Some of them are bicycles, some of them are tricycles, and two of them have four wheels. John counts all the wheels and gets 100, in total. How many tricycles are there?
Answer:
16 tricycles
Step-by-step explanation:
First, let's make a chart:
Bicycles- x bicycles and 2x wheels
tricycles- y tricycles and 3x wheels
Four wheeled vehicles- 2 bikes (given), 8 wheels
Since the total amout of bikes is 40, that means that x+y+8=40
You can simplify that to x+y=38.
now, we're going to form another equations dealing with the number of wheels.
Since we know that four wheeled vehicles already have only 8 wheels, then that means 2x+3y=92
Solve the system of equations:
2x+3y=92
x+y=38
y will be 16
An equation is formed of two equal expressions. There are a total of 16 tricycles.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the total number of bicycles be represented by x, while the total number of tricycles is represented by y.
The total number of vehicles is 40. Therefore, we can write the equation as,
x + y + 2= 40
x + y = 38
Solving the equation for x,
x = 38-y
Also, given that the total number of wheels is 100, also, the number of four-wheelers is 2. Therefore, the total number of wheels can be written as,
2x + 3y + 2(4) = 100
2x+ 3y = 92
Substitute the value of x from the above equation,
2(38 - y) + 3y = 92
76 - 2y + 3y = 92
y = 16
Hence, there are a total of 16 tricycles.
