The payment to a clown for a children's party is directly proportional to the number of
children under 12 at the birthday party. The clown earns $140 at a party that has 10 children attending,
.
How much will the clown earn when 22 children under the age of 12 attend?
If the clown uses 46% of the money earned on his props for the party, and the rest is
profit. What is the profit if only 10 children under the age of 12 attend the party?
Answer:
Step-by-step explanation:
We know he earns $14 per child under 12
So he'll earn 22 times 14 which is $308 earned.
46% of 308 is basically 0.46 X 308=$141.68 spent on props.
He profits $166.32
If only 10 children attend.
He earns 10 times 14= $140
46% of these earnings is for props and 54% is profit so
0.54 X 140=$75.60.
Thus he profits $75.60 if 10 children attended.
The profit will amount to $75.60 when only 10 children under the age of 12 attend the party.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We are aware that he receives $14 for each child under the age of 12.
Thus, he will make $308 after multiplying 22 by 14.
In other words, 46% of 308 is 0.46 × 308 or $141.68 spent on props.
He earns $166.32.
If just 10 kids show up.
He makes $10 multiplied by 14 for a total of $140.
Props account for 46% of these revenues, while profits make up 54%, therefore
0.54 × 140=$75.60.
So, if 10 kids showed up, he makes $75.60.
Thus, the profit will amount to $75.60 when only 10 children under the age of 12 attend the party.

An arithmetic sequence has this recursive formula: a1=8 an=an-1-6 what is the explicit formula for this sequence
Answer:
D
Step-by-step explanation:
a p e x
The explicit rule of the sequence is (d) [tex]a_n = 8-6 (n -1)[/tex]
How to determine the explicit formula?The sequence is given as:
a1 = 8
[tex]a_n = a_{n-1} - 6[/tex]
Set n = 2
[tex]a_2 = a_{1} - 6[/tex]
This gives
a2 = 8 - 6
a2 = 2
Calculate the common difference (d)
d = a2 - a1
This gives
d = 2 - 8
Evaluate
a = -6
The explicit formula is then calculated as:
[tex]a_n = a_1 + (n -1)d[/tex]
This gives
[tex]a_n = 8-6 (n -1)[/tex]
Expand
[tex]a_n = 8-6n +6[/tex]
Evaluate the like terms
[tex]a_n = 14-6n[/tex]
Hence, the explicit rule of the sequence is (d) [tex]a_n = 8-6 (n -1)[/tex]

Last winter in the northeast the temperature was 5degrees Fahrenheit at midnight. It dropped 3 degrees every hour for 3hours and then rose 8 degrees every hour after that. What was the temperature at noon?
Answer:
68 [tex]^\circ F[/tex]
Step-by-step explanation:
Initial temperature in the northeast in the midnight = 5 [tex]^\circ F[/tex]
Drop for the next three hours = 3 degrees per hour.
Temperature after the 3 hours = 5 [tex]^\circ F[/tex] - 3 - 3 - 3 = - 4[tex]^\circ F[/tex]
Now, it is given that the temperature is rising 8[tex]^\circ F[/tex] every hour.
3 hours have already passed from the midnight.
Now, there are 9 more hours till noon.
So, the temperature at noon can be found by adding 8 for 9 times in the temperature after 3 hours.
Temperature at noon = - 4 + 8 + 8 .... 9 times
Temperature at noon = - 4 + 9 [tex]\times[/tex] 8 = -4 +72 = 68[tex]^\circ F[/tex]
Therefore, the answer is: 68[tex]^\circ F[/tex]

The expression ( x − 12 ) is a factor of x 2 + p x − 48 . What is the value of p ?
Answer:
p = -8
Step-by-step explanation:
Since, (x - 12) is a factor, then;
x - 12 = 0
x = 12
substitute the value of x in the equation
[tex]x^{2}[/tex] + px - 48 = 0
[tex](12)^{2}[/tex] + 12p - 48 = 0
144 + 12p -48
12p = -144 + 48
12p = -96
p = -8
So that,
[tex]x^{2}[/tex] +-8x - 48 = 0
[tex]x^{2}[/tex] -12x + 4X- 48 = 0
([tex]x^{2}[/tex] -12x) + (4X- 48)
X(X - 12) + 4(X - 12)
(X - 12) (X + 4)
Therefore, p = -8 and (X - 12) (X + 4) are factors of the equation.

A company offers a nut mixture with 4 peanuts for every 3 almonds. The company changes the mixture to have 8 peanuts for every 3 almonds, but the number of nuts per container does not change. How many nuts are in the smallest possible container?
Answer:
77 nuts
Step-by-step explanation:
From the above question:
We have ratio
Peanuts : Almonds
The original mixture is given as:
A company offers a nut mixture with 4 peanuts for every 3 almonds.
4 : 3
The sum of the proportion = 7
Hence, there are 7 nuts in the container
The new mixture
The company changes the mixture to have 8 peanuts for every 3 almonds,
8 : 3
Sum of the proportion = 11
We are told : the number of nuts per container does not change.
How many nuts are in the smallest possible container?
To solve this, we use the Lowest Common Multiple principle
We find the L. C. M of 7 and 11
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91
Multiples of 11:
11, 22, 33, 44, 55, 66, 77, 88, 99
Therefore,
LCM(7, 11) = 77
Therefore, the number of nuts in the smallest possible container is 77 nuts

1. ¿Cuál de las siguientes ecuaciones responderá a la siguiente pregunta? Marque todo lo que corresponda.
“Pienso en un número, le sumo 7 y luego lo multiplico por 4.
Mi respuesta es 80. ¿Cuál era mi número?”
The correct option is B. 4(x+7) = 80.
Adding 7 to the number then multiplying it with 4 given the result 80 is shown by the equation; 4(x+7) = 80.
What is defined as the mathematical operations?Calculating a value with operands as well as a math operator is referred to as a mathematical "operation." The math operator symbol has predefined rules that must be applied to a given operands and numbers.
Operands are the numbers that are used in an operation. The operands are given different names depending on the type of operation.An operator is a symbol that represents a mathematical operation, such as:+ for addition− for subtraction× for multiplication÷ for division = equal to denotes equivalence, indicating that left hand side value is equal to a right hand side value.Now as per the given question;
Let us assume that the given number is 'x'.
Adding 7 to this number will form; x + 7.
Now, multiplying the number resultant number with 4 gives; 4(x + 7)
Now the number formed is equal to the result 80.
Thus, 4(x + 7) = 80.
Therefore, the equation which correctly represents the given formation is 4(x + 7) = 80.

It should be noted that the value of the expression 5 - 2 - 2 + 10 will be 11.
How to illustrate the information?Mathematical operators like addition, subtraction, multiplication, and division are used to create expressions in writing.
You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.
For example, x + 6 = 12. Since 6 + 6 equals 12, the variable x in the example above is equal to 6. We can substitute the variables with their values and then evaluate the expression if we know the values of our variables.

Una heladeria dispone de 20 frutas distintas para elaborar sus malteadas. Si los clientes pueden elegir tres sabores para mezclar, cuantas malteadas de tres sabores distintos puede elegir un cliente en esa heladeria
Answer:
Existen 6840 permitaciones de malteadas de tres sabores distintos que la heladería puede ofrecer.
Step-by-step explanation:
En este caso, el cliente que adquiere una malteada de tres sabores distintos sigue el siguiente procedimiento:
1) El primer sabor sale de cualquiera de las 20 frutas disponibles.
2) El segundo sabor es distinto al primer sabor, es decir, que sale de las 19 frutas restantes.
3) El tercer sabor es distinto al primer sabor y al segundo sabor, es decir, que sale de las 18 frutas restantes.
Puesto que existe una doble conjunción y que puede importar el orden según la preferencia del cliente, se habla matemáticamente de una permutación, definida como:
[tex]n\mathbb{P}k = \frac{n!}{(n-k)!}[/tex] (1)
Donde:
[tex]n[/tex] - Número de sabores disponibles, adimensional.
[tex]k[/tex] - Número de sabores escogidos, adimensional.
Si tenemos que [tex]n = 20[/tex] y [tex]k = 3[/tex], entonces la cantidad de malteadas de tres sabores distintos es:
[tex]n\mathbb{P}k = \frac{20!}{(20-3)!}[/tex]
[tex]n\mathbb{P}k = \frac{20!}{17!}[/tex]
[tex]n\mathbb{P}k = 20\cdot 19\cdot 18[/tex]
[tex]n\mathbb{P}k = 6840[/tex]
Existen 6840 permitaciones de malteadas de tres sabores distintos que la heladería puede ofrecer.
