Si el recíproco del m% de p se divide por el recíproco del m% de q resulta: A) pq/100 B)pq C)1/pq D)p/q E)q/p

Answers

Answer:

E) q / p

Step-by-step explanation:

Spanish

m% de p = pf / 100

m% de q = mq / 100

El recíproco se obtiene haciendo que el numerador sea el denominador y el denominador el numerador.

El recíproco de m% de p = 100 / mp

El recíproco de m% de q = 100 / mq

Divisor

100 / mp / 100 / mq

= 100 / mp * mq / 100

= mq / mp

= q / p

English

If the reciprocal of m% of p is divided by the reciprocal of m% of q, the result is: A) pq / 100 B) pq C) 1 / pq D) p / q E) q / p

m% of p= mp/100

m% of q= mq/100

The reciprocal is obtained by making the numerator the denominator and the denominator the numerator

The reciprocal of m% of p= 100/mp

The reciprocal of m% of q= 100/mq

Dividing

100/mp/ 100/mq

=100/mp* mq/100

= mq/mp

= q/p

As you see, 2/10 = 8/40
2/4 = x/40, multiply by 10
2/4 = 20/40
Then add because same denominator
Now you would get:
8/40 + 20/40 = 28/40

Answer:

8/40 + 20/40 = 28/40

Step-by-step explanation:

It's about finding the common denominator for the fractions.

we can easily see that 40 is a common denominator for denominators 10 and 4. 20 would work too, but 40 is "instantly seen".

2/10 = (2*4) / (10*4) = 8/40

2/4 = (2*10) / (4*10) = 20/40

8/40 + 20/40 = (8+20) / 40 = 28/40

In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?

a = 3
a = 8
a = 18
a = 33

Answers

Answer: C: A=18

Step-by-step explanation: If your are adding 5 every time the x value goes up by one, then you would add 5 to13, henceforth getting 18.

The value of a that completes the table is 18

Rate of change of a function

The rate of change of a function is expressed in term of the slope.

In order to determine the value of a, we will use the expression below;

Slope = a - 13/4-3 = 23-13/5-3
a-13 = 10/2

a - 13 = 5

Add 13 to both sides

a =5 + 13

a = 18

Hence the value of a that completes the table is 18

Which expression is equivalent to the image below?
1/4(12-3x)

A. 3 - 3/4x
B. 3 - 12x
C. 3 + 3/4x
D. -3 -3x

Answers

The answer is A

You’d solve the parenthesis first because it’s the first step in PEDMAS so you’d multiply everything in the parenthesis by 1/4. 12 times 1/4 is 3 and -3x times 1/4 is -3/4. (1/4 times -3/1 and you multiply the numerators and denominators) when you put each 3 and -3/4x together you get 3-3/4x

Sorry it’s wordy, I hope it makes sense.

The expression is equivalent to the 1/4 (12 -3x) is 3 - 3/4x.

What is Expression?

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.

We have the Expression

1/4 (12 - 3x)

Now, using Distributive Property we get

a x (b+ c) = a x b + a x c

Then, 1/4 (12 - 3x)

= 1/4(12) - 1/4 (3x)

= 3 - 3/4x

Thus, the required expression is 3 - 3/4x.

Calcula y comprueba las ecuaciones: plisss lo necesito alguien me puede ayudar a) 2X = 6 b) 10 + Z = 20 c) P + 9 = 11 d) 3X + 8 = + 29 e) 2U + 8 = 10

Answers

Answer:

a) x=3

b) z=10

c) P= 2

d) X=7

e) U=1

Step-by-step explanation:

Resolver una ecuación consiste en hallar los valores de la variable que hacen cierta la igualdad.

a) 2x= 6

El coeficiente es el número junto a la variable. En este caso, el coeficiente es 2. Para eliminar este número en la expresión 2x, debido a que la variable x esta multiplicada por 2, deberás dividir ambos lados de la ecuación entre 2, debido a que la operación opuesta de la multiplicación es la división.

(2x)÷2=6÷2

x= 3

Comprobar la solución de una ecuación se hace al remplazar la variable en una ecuación con el valor de la solución. La solución debería satisfacer la ecuación cuando se ingresa en esta.

En este caso:

2*3= 6

6=6

b) 10 + z= 20

En este caso se debe sumar o restar la constante que se encuentra acompañando a la variable en ambos lados de la ecuación de manera de aislar el término de la variable. En este caso:

10 - 10 + z= 20 -10

z= 10

Comprobación:

10 + z=20

10 + 10=20

20=20

c) P + 9= 11

P +9 - 9= 11 -9

P=2

Comprobación:

2 + 9= 11

11=11

d) 3X + 8 = 29

En este caso, se suma o resta la constante en ambos lados de la ecuación y luego se elimina el coeficiente de la variable mediante la división o multiplicación. Esto es:

3X + 8 - 8= 29 - 8

3X= 21

3X ÷3= 21÷3

X=7

Comprobación:

3*7 + 8=29

21+8=29

29=29

e) 2U + 8= 10

2U + 8 - 8= 10 -8

2U= 2

2U ÷2= 2÷2

U=1

Comprobación:

2*1 + 8= 10

2 + 8= 10

10=10

Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Nelson owes $950

Answers

Answer:

950, 1121.00, 1322.78, 1,560.88, 1,841.84

Step-by-step explanation:

Calculation to determine the sequences that describes his increasing monthly balance

Based on the information given in order for us to determine the sequence we have to multiply the amount owes by the interest rate and then add back the answer you got to the previous amount you multiplied the interest rate to.

First sequence will be the amount he owes on a credit which is $950

Second sequence

950 * .018 = 171.00

950 + 171.00 = 1121.00

Third sequence

1121.00 * .018 = 201.78

1121.00 + 201.78 = 1322.78

Fourth sequence

1322.78*0.18=238.10

1322.78+238.10=1,560.88

Last sequence

1,560.88*0.18=280.96

1,560.88+280.96=1,841.84

Therefore the sequences that describes his increasing monthly balance are:

950, 1121.00, 1322.78, 1,560.88, 1,841.84

Zeroes of a polynomial can be determined graphically. Number of zeroes of a polynomial is equal to number of points where the graph of polynomial.

2 points

a. intersects y-axis

b. intersects x-axis

c. intersects y-axis or intersects x-axis

d. none of these​

Answers

9514 1404 393

Answer:

  b. intersects x-axis

Step-by-step explanation:

A zero of the polynomial is where y = 0. The equation y = 0 is the equation of the x-axis, so intersections of the graph of the function with the x-axis are places where the function value is zero.

The number of (distinct real) zeros is equal to the number of points where the graph intersects the x-axis.

_____

Additional comment

When (x -p)^n is a factor of the polynomial, the graph will intersect the x-axis at x=p. The zero is said to have "multiplicity n". For odd values of n, the graph will cross the x-axis (change sign) at x=p. For even values of n, the graph will touch the axis at x=p, but will not cross there.

So, the number of intersections with the x-axis tells the number of distinct real zeros, but does not say anything about their multiplicity. Complex zeros will not cause the graph to touch the x-axis.

The probability that a randomly selected student is on honor roll is 0.24 The probability that a randomly selected student is on the honor roll and takes an art class is 0.18 what is the probability that a randomly selected student takes an art class, given the student is on honor roll

Answers

Answer: 0.06

Step-by-step explanation: subtract them and you'll get your answer

The probability that a randomly selected student takes an art class, given the student is on honor roll is P ( A|B ) = 0.75

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

The conditional probability is given by

P(A|B) = P(A and B) / P(B)

where A and B are events.

In this case, let A be the event that a randomly selected student takes an art class, and let B be the event that the student is on honor roll.

The probability that a selected student is on honor roll P ( B ) = 0.24

The probability that a selected student is on honor roll and takes an art class P (A and B) = 0.18

Now ,  the probability that a randomly selected student takes an art class, given the student is on honor roll P(A|B) = P(A and B) / P(B)

P(A|B) = P(A and B) / P(B) = 0.18 / 0.24 = 0.75

Hence , the probability is 0.75 or 75%
