The probability that Ben will find two worthless $10 bills in his wallet is practically impossible.
What is Probability?Probability is a branch of mathematics that deals with the likelihood of an event occurring. It is the measure of the likelihood of an event occurring divided by the number of possible outcomes. Probability is used to determine the chances of a particular outcome occurring and can range from 0 to 1.
The probability that each bill will be a worthless $10 bill is very low. This is because the US Federal Reserve has discontinued the production of $10 bills in 2006, so the likelihood of finding two of them in circulation is highly unlikely. Additionally, bills are often replaced after a certain amount of time due to wear and tear, so the probability of finding two bills in circulation that are both from the discontinued series is even lower.
The chances of finding two $10 bills from the discontinued series in circulation is so extremely rare that it has been estimated to be one in ten million. Even though it is possible to find two bills from the discontinued series, it is extremely unlikely that one would carry two of them in their wallet. Therefore, the probability that Ben will find two worthless $10 bills in his wallet is practically impossible.

Kennedi is feeding her 5 puppies. She has half a bag of dog food left. How much of the bag
will each puppy receive?
Answer:
1/10
Step-by-step explanation:
Puppy food portions.
Unish Baskota
Kennedi is feeding her 5 puppies. She has half a bag of dog food left. How much of the bag
will each puppy receive?
If Kennedi has half a bag of dog food left and she has 5 puppies to feed, then each puppy will receive 1/5th of the remaining dog food.
To calculate this, you can divide the remaining dog food (which is half a bag) by the number of puppies (which is 5):
1/2 bag of dog food ÷ 5 puppies = 1/10 bag of dog food per puppy
So each puppy will receive 1/10th of the bag of dog food.
Each puppy would receive 1/10 of food

The final inequality that represents how many blankets Elle can make in her workshop would be:
3x ≤ 52 and x ≥ 16
What is Inequality ?In mathematics, an inequality is a statement that compares two values or expressions using an inequality symbol such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "≠" (not equal to).
An inequality indicates that one value or expression is smaller, greater, or not equal to the other value or expression.
The inequality "y <= 10" states that the value of "y" is less than or equal to 10.
Let "x" be the number of blankets Elle can make in her workshop.
Since each blanket requires 3 ft. of material, the total amount of fleece required for "x" blankets would be 3x ft.
We know that Elle has 52 ft. of fleece in her workshop, so we can set up the inequality:
3x ≤ 52
This inequality states that the amount of fleece required for "x" blankets must be less than or equal to the amount of fleece Elle has available.
To satisfy the condition of making at least 16 blankets, we can add the requirement that "x" must be greater than or equal to 16.

Viola has covered a horizontal distance of 199.7 meters when driving 200 meters up a hill that makes an angle of 3 degrees with the horizontal.
What horizontal distance has she covered?Viola drives 200 meters up a hill that makes an angle of 3 degrees with the horizontal. To find the horizontal distance she covered, we can use the cosine formula:
Cos(θ) = adjacent/hypotenuse
In this case, the adjacent side is the horizontal distance we are trying to find, the hypotenuse is the distance she drove (200 meters), and the angle is 3 degrees. Plugging in these values, we get:
Cos(3º) = adjacent/200
Rearranging the equation to solve for the adjacent side, we get:
adjacent = 200*cos(3)
Using a calculator, we find that cos(3) is approximately 0.9986. Multiplying this by 200 gives us:
adjacent = 199.72
Therefore, the horizontal distance that Viola covered is approximately 199.72 meters.

In the given question, the rocket will hit the ground in 7 seconds. The width of the rectangle is 3 cm. Kirk makes the wall in 5.5 hours. The student needs 97 marks.
The relation between the height and the time of the toy rocket has been given in the question as,
h = -4.9t²+33.6t + 4.9
where,
h= height of the rocket after getting launched
t= time after which the rocket has been launched
So, if we have to calculate how much time the rocket takes to reach the ground,
we have to take h=0 (at ground).
So, the equation becomes
0 = -4.9t²+33.6t + 4.9
Now, the roots of this equation will give the time at which the rocket will hit the ground.
So, after calculating we get
t = -0.1428 sec
or
t = 7 sec
since negative time is not possible,
the time at which the rocket will hit the ground is 7 seconds.
The length of the rectangle is = 5b-7 cm
Hence, the area is = b(5b-7) = 24
Hence, the width comes out to be = 3 cm
Kirk would be able to make the wall in 5.5 hours. This is because Jeff can make it one hour earlier than him i.e., K-1 hours. So, we get -
= (K-1) + K = 10
= 2K = 11
= K = 5.5 hours

If y*=y1/2(y2+1) then -3(16* - 9*) = -10.5y1(y2 + 1), called polynomial.
What is a polynomial?A polynomial is an expression that consists of variables, numbers, and operations (like addition, subtraction, multiplication, and division). It is similar to a mathematical equation, but instead of an equals sign, it uses coefficients and variables in a power form. The power of a polynomial is determined by the highest power of the variables in the expression.
For example, if the polynomial is x2 + 5x + 2, then the power is 2. Polynomials are used in many areas of mathematics, such as calculus, algebra, and number theory.
If y*= y1/2(y2+1) then -3(16* - 9*)
= -3(16(y1/2(y2 + 1)) - 9(y1/2(y2 + 1)))
= -3(8y1(y2 + 1) - 4.5y1(y2 + 1))
= -3(3.5y1(y2 + 1))
= -10.5y1(y2 + 1)
In this problem, 16* is equal to 16(y1/2(y2 + 1)) and 9* is equal to 9(y1/2(y2 + 1)). When -3 is multiplied to 16* - 9*, the result is -3 times the difference of 16* and 9*. The expression then simplifies to -10.5y1(y2 + 1).

∫³⁰⁰₀ (11 (1-t/300)⁷ / 250000 * t³) * dt
∫³⁰⁰₀ -11 / 250000 * (t-300)⁷ * t³ * (1/300)⁷ dt
= -11 (1/300)⁷ / 250000 ∫³⁰⁰₀ (t-300)⁷ * t³ * dt
Now Integrate with respect to 't'
using substitution
Let u = t-300
du = dt
∫ u⁷ * (u + 300)³ * du
∫ (u¹⁰ + 900 u⁹ +270000 u⁸ + 27000000 u⁷) * du
= u¹¹/11 + 90 u¹⁰ + 30000 u⁹ + 3375000 u⁸
Undo the substitution
u= (t-300)
= [ (t-300)¹¹ / 11 + 90 (t-300)¹⁰ + 30000(t-300)⁹ + 337500(t-300)⁸]³⁰⁰₀
Substitutes the limits
= [0- ((-300)¹¹/ 11 + 90 * (-300)¹⁰ + 30000 * (-300)⁹ + 3375000 * (-300)⁸]
= 270 people
b) Constant rate of 0.7 people per second
This is the rate of exit
at t = 0.20 people in line
People in a line at t = 300 is = 20+ ∫³⁰⁰₀ ((r(t) - 0.7 ) * dt
= 20 + ∫³⁰⁰₀ 44(t/100)³ * (1-t/300)⁷- 0.7 dt
= 20 + 270 - 0.7 * 300
= 80 people
c) t = 300 sec
people = 80
when t>300 , r(t) = 0
rate of exit remains the same
= 80 + ∫ ( 0-0.7) * dx
= 80 + [-0.7x] = 0
= 80 - [0.7x] = 0
= 80 - 0.7 t + 0.7 * 300 = 0
= 80 - 0.7t + 210 = 0
= - 0.7 t = -290
t = 414.285714 sec.
d) f(t) = 20 + ∫⁶₀ (r(x) - 0.7) * dx
f(t) = r(t) - 0.7
f(t) = 0 (for critical point)
r(x) = 44 (t/100)³ * (1-t/300)⁷
r(t) = 0
we get t= 33.0133 sec.
t = 166.575 sec.
Now check for the value
when t=0
f(t) 20
when t= 33.0133
f(t) = 3.803 ≈ 4
when t = 166.575
f(t) = 158.07 ≈ 158
when t= 300
f(t) = 80
so the minimum number of people is 4 at the time t= 33. 0133

The measures of the unknown angles are
x = 46
and
y = 88
Calculating the measures of the unknown angles in the triangleFrom the question, we are to determine the measures of the unknown angles in the triangle.
From the diagram, we can observe that the triangle is an isosceles triangle as the legs of the triangle are congruent to each other.
Since the triangle is an isosceles triangle, the base angles of the triangle must be equal
The base angles are 46° and x°
Thus,
x = 46
Also,
We can write that
y° + 46° + x° = 180° (Sum of angles in a triangle)
y° + 46° + 46° = 180°
y° + 92° = 180°
y° = 180° - 92°
y° = 88°
Thus,
y = 88
Hence, x = 46 and y = 88
