CONSIDERANDO QUE A U B= { 1,2,3,4,5,6,7,8}, A U B = {4,5} e A-B = { 1,2,3}, DETERMINE O CONJUNTO B

Answers

Answer:

O conjunto B é dado por: B = {4, 5, 6, 7, 8}

Step-by-step explanation:

A U B= { 1,2,3,4,5,6,7,8}

Todos os elementos pertencem a pelo menos um desses conjuntos.

A intersecção B = {4,5}

Os elementos 4 e 5 pertencem a pelo menos um desses conjuntos. Então, tem-se os dois primeiros elementos de B, que são 4 e 5.

A-B = { 1,2,3}

1, 2, 3 são os elementos que pertencem ao conjunto A e não pertencem ao conjunto B.

Como A U B= { 1,2,3,4,5,6,7,8}, tem-se que os elementos 4, 5, 6, 7 e 8 pertencem ao conjunto B.

O conjunto B é dado por: B = {4, 5, 6, 7, 8}

Samantha went to a concession stand and bought three pretzels and four sodas and paid a total of $11.25 for them. Raza went to the same stand and bought five pretzels and two sodas and paid a total of $8.25.
(a) Could pretzels have cost \$1.75 each and sodas $1.50 each ? How can you evaluate based on the information given ?
(b) Letting x equal the unit cost of a pretzel and letting y equal the unit cost of a soda, write a system of equations that models the information given .
(c) Solve the system of equations using the elimination method or a matrix,
(d) Leah went to the same concession stand and bought two sodas, how many pretzels would she need to buy so that she spent the same amount on both

Answers

Answer:

No, because their respective prices are $0.75 and $2.25

Step-by-step explanation:

Let's assume that the price of each pretzel is x and the price of each soda is y

3x + 4y = 11.25_____ equation 1

5x + 2y = 8.25_____ equation 2

Multiply equation 2 by the figure 2 so as to have both equation sharing the same coefficient of y

10x + 4y = 16.5____ equation 1

3x + 4y = 11.25____ equation 2

Now subtract equation 2 from 1

7x = 5.25

X = 5.25/7

X = 0.75

Now substitute x = 0.75 in equation 1

10x + 4y = 16.5

10(0.75) + 4y = 16.5

7.5 + 4y = 16.5

4y = 16.5 - 7.5

4y = 9

Y = 2.25

Therefore,the cost of each pretzel is $0.75 while that of soda is $2.25

Emily enters a bike race for charity her mother pledges 10 cents for every 0.75 mile she bikes if Emily bikes 15 miles how much will her mom donate

Answers

Answer:

The answer is that her mom will donate $2.

Step-by-step explanation:

From the information given, you can use a rule of three to find the amount her mom will donate if Emily bikes 15 miles given that her mother pledges 10 cents for every 0.75 miles:

0.75 miles → 0.10

  15 miles  →    x

x=(15*0.10)/0.75

x= 2

According to this, the answer is that her mom will donate $2.

A truck can be rented from Company A for $160 a day plus 0.60 per mile. Company B charges $80 a day plus 0.70 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

At __ miles, the rental costs are the same from other company.

Answers

Answer:

800 miles

Step-by-step explanation:

Let the amount of miles = m

Company A charges a flat rate of $160 a day, and $0.60 per mile:

total = 0.60m + 160

Company B charges a flat rate of $80 a day, and $0.70 per mil:

total = 0.70m + 80

Set both equations equal to each other:

0.60m + 160 = 0.70m + 80

Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Subtract 0.70m and 160 from both sides:

0.60m (-0.70m) + 160 (-160) = 0.70m (-0.70m) + 80 (-160)

0.60m - 0.70m = 80 - 160

Simplify:

-0.10m = -80

Isolate the variable, m. Divide -0.10 to both sides:

(-0.10m)/(-0.10) = (-80)/(-0.10)

m = 80/0.10

m = 800

At 800 miles, the rental costs are the same.

Greg said that he wrote a fraction greater than 3/12, is less than 75/100, and has 6 as a denominator. What is his fraction?

Answers

Given:

A fraction is greater than [tex]\dfrac{3}{12}[/tex], is less than [tex]\dfrac{75}{100}[/tex].

The fraction has 6 as a denominator.

To find:

The fraction value.

Solution:

Let x be the required fraction.

According to the given information, we get

[tex]\dfrac{3}{12}<x<\dfrac{75}{100}[/tex]

[tex]\dfrac{1}{4}<x<\dfrac{3}{4}[/tex]

We know that, [tex]\dfrac{1}{4}<\dfrac{2}{4}<\dfrac{3}{4}[/tex]. So,

[tex]x=\dfrac{2}{4}[/tex]

[tex]x=\dfrac{1}{2}[/tex]

We need 6 as the denominator.

Multiply the numerator and denominator by 3.

[tex]x=\dfrac{1\times 3}{2\times 3}[/tex]

[tex]x=\dfrac{3}{6}[/tex]

Therefore, the required fraction is [tex]\dfrac{3}{6}[/tex].

The fraction that Greg wrote is 3/6.

What is a fraction?

A fraction is a quantity that is not a whole number. A fraction usually has a numerator and a denominator. The numerator is the number above. While the denominator is the number below. An example of a fraction is 1/2.

What fraction did Greg write?

The first step is to express 3/12 and 75/100 in its simplest form.

3/12 = 1/4

75/100 = 3/4

The second step is to determine the difference between the fractions

3/4 - 1/4

[tex]\frac{3 - 1}{4}[/tex] = [tex]\frac{2}{4} = \frac{1}{2}[/tex]

The third step is to multiply by 3

3/6
