Answer:
$137.80
Step-by-step explanation:
We can solve for [tex]\frac{1}{3}[/tex] of Luis's money using this equation:
373.24 ÷ 3 = 124.41 (Rounded to the nearest hundredth)Subtracting that from the total cost:
400 - 124.41 = 275.59275.59 is the leftover cost of the new gaming console that the siblings have to evenly split. To find out how much the sibling have to pay each, you can use this equation:
275.59 ÷ 2 = 137.80 (rounded to the nearest hundredth)Therefore, to pay for the new gaming console, Benjamin and Audrey will need to each contribute $137.80 to evenly pay for the remaining cost.
find the probability that he lands it on the tenth try. while a generic rule for finding probability that he first lands the bottle on the floor
Without more information about the specific situation (such as the height from which the bottle is dropped, the surface on which it is dropped, and so on), a value for p cannot be determined.
The probability of landing a bottle on the floor on any given try is a fixed value, typically represented by "p".
The probability that he will land the bottle on the floor on the tenth try is then given by:
P(tenth attempt landing) = (1 - p)9 * p
where (1 - p)9 represents the probability that he fails to land the bottle on the floor in the first nine attempts, and p represents the probability that he lands the bottle on the floor on the tenth attempt.
However, without more information about the specific situation (such as the height from which the bottle is dropped, the surface on which it is dropped, and so on), a value for p cannot be determined.

Calculators were purchased at $80 per dozen and sold at $25 for three calculators. What is the profit on six dozen calculators?
Answer:
$120
Step-by-step explanation:
Buying price
$80×6= $480
Selling price
$25×4×6= $600
Profit
$600-$480=$120
The profit on six dozen calculators is $120.
To calculate the profit on six dozen calculators, we need to find the cost of purchasing six dozen calculators and the revenue from selling six dozen calculators.
Step 1: Calculate the cost of purchasing six dozen calculatorsSince each dozen costs $80, the cost of purchasing six dozen calculators is:
$80 x 6 = $480
Since three calculators are sold for $25, the revenue from selling six dozen calculators is:
$25 x (6 x 12/3) = $25 x 24 = $600
The profit is the revenue minus the cost:
$600 - $480 = $120
The profit on six dozen calculators is $120.

Verify that the indicated function is an explicit solution of thegiven differential equation. Assume an appropriate intervalI of the definition for each solution.
dy/dt + 20y = 24; y = 6/5 - (6/5)e-20t
To verify that the given function is an explicit solution of the given differential equation, we can plug it into the differential equation and see if it satisfies the equation.
Plugging in the given function, we get: dy/dt + 20y = 24; (6/5)e-20t - 6/5 = 24. Simplifying, we get 0 = 0, which is true. This means that the given function is an explicit solution of the differential equation, and it is valid on any interval I.
To find a function solution to a differential equation, you must first identify the type of equation you are dealing with. If it is a linear equation, you can use the method of integrating factors or the method of undetermined coefficients, depending on the equation.
If it is a nonlinear equation, you can use the method of separation of variables, the method of substitution, or the method of series solutions. Once you have identified the equation, you can use the appropriate method to find the solution.

Answer:
Step-by-step explanation:
The hydrogen ion concentration of a solution can be calculated from the pH using the equation:
[H*] = 10^(-pH)
So for the apple juice with a pH of 3.1:
[H*(apple juice)] = 10^(-3.1) = 0.0005
And for the drinking water with a pH of 8.3:
[H*(drinking water)] = 10^(-8.3) = 1.7 x 10^(-9)
To find the ratio of the hydrogen ion concentration in apple juice to that in drinking water, we divide the concentration of the apple juice by the concentration of the drinking water:
[H*(apple juice)] / [H*(drinking water)] = 0.0005 / (1.7 x 10^(-9)) = 2.94 x 10^9
Therefore, the hydrogen ion concentration in apple juice is 2.94 x 10^9 times the concentration in drinking water.

X(x+8)=-20
Help solve with work
Answer:
-4+4i and -4-4i
Step-by-step explanation:
To start off, we can distribute the x into the x+8 to get x^2 + 8x = -20. From here we can create a polynomial by moving the -20 to the other side by adding 20 to both sides to get x^2 + 8x +20 =0. From here we can check if there is any real solutions by finding the discriminant (the sqrt part of the quadratic formula) so 8^2-4(1)(20). 16-80. Because this gets us a negative number in an actual square root, there answers we would get would be imaginary.
However to solve what the roots are, we would plug the entire equation into the quadratic equation. Getting -8+- sqrt(-64)/2 which simplified is -4+-4i. Therefore our two answers are -4+4i and -4-4i

let ct number of children in indiana at the beginning of year t, and at number of adults in indiana at the beginning of year t. during any given year, 5% of all children
In Indiana become adults, and the number of children in Indiana increases by 2% as a result of births and immigration. If we let c0 = 6 million and a0 = 4 million.
Then the population of Indiana can be modeled by the following recursive equation:
ct = (1 + 0.02) * ct-1 + 0.05 * at-1
at = (1 - 0.05) * ct-1
This equation models the growth of the population of Indiana based on the number of children and adults in the previous year, taking into account the conversion of children into adults and the growth in the number of children.
The given information states that during any given year, 5% of all children become adults, while adults stay the same. Hence, the number of adults in year t can be determined as follows:
at = (1 + 0.05) * ct-1
Where ct-1 is the number of children in the previous year. This equation reflects that the number of adults in year t is the sum of the adults from the previous year plus 5% of the children in the previous year.
This model assumes that the growth in the number of adults is solely dependent on the children becoming adults, and no other factors, such as migration, birth, or death, are considered. This model is also based on the assumption that 5% of the children will become adults each year, which may not hold true in reality.

two supplementary angles are in the ratio of 2 to 3 the number of degrees in the smaller angle is what
the number of degrees in the smaller angle is 60 degrees.
The smaller angle is 60 degrees.
Let x = number of degrees in the smaller angle
Then the number of degrees in the larger angle = 3x
Given that the two angles are in the ratio of 2 to 3
2x = 3x
x = 60
Therefore, the number of degrees in the smaller angle is 60 degrees.
The two supplementary angles are supplementary angles because the sum of their angles is 180 degrees. This means that if we denote the number of degrees in the smaller angle as x, then the number of degrees in the larger angle must be 180-x. We know that their ratio is 2 to 3, which can be written as 2x = 3(180-x). Solving this equation gives us x = 60, so the number of degrees in the smaller angle is 60.
