2: 90

Step-by-step explanation:

Answer:

In 12 minutes, She can answer 30 math questions.

In 36 minutes, She can answer 90 math questions.

Step-by-step explanation:

Jill can answer 50 math questions every 20 minutes.

1)

How many questions can she answer in 12 minutes

Let (x) represent the number of questions she can answer in 12 minutes:

So, if 50 math question = 20 minutes

   and (x) math question = 12 minutes

To  solve for (x); we have:

(x) × 20 minutes = 50 math question × 12 minutes

(x)  = [tex]\frac{50*12}{20}[/tex]

(x)  = [tex]\frac{600}{20}[/tex]

(x)  = 30 math questions

∴  In 12 minutes, She can answer 30 math questions.

2)

How many math questions can she answer in 36 minutes?

Let (y) represent the number of questions she can answer in 36 minutes:

So, if 50 math question = 20 minutes

   and (y) math question = 36 minutes

To  solve for (y); we have:

(y) × 20 minutes = 50 math question × 36 minutes

(y) = [tex]\frac{50*36}{20}[/tex]

(y) = [tex]\frac{1800}{20}[/tex]

(y) = 90 math questions.

∴  In 36 minutes, She can answer 90 math questions.

To answer this question, we pose the problem as follows:

It is known that there are 7 posters and between them there is 0.2 meters of separation, we also know that between the beginning of the corridor and the first poster of 0.2 meters, and between the last poster and the end of the corridor there is 0.2 meters from separation . That is, there is a total of 8 separations of 0.2 meters in the corridor.

This is the real length of the corridor occupied by the posters.

[tex]4.4-8(0.2)\\[/tex]

So, if we call x the length of the posters, we can write the following equation for x

[tex]x =\frac{4.4-8(0.2)}{7}\\[/tex]

[tex]x = 0.4 meters\\[/tex]

Then the length of the posters is 0.4 meters

1.4 as a fraction is 1 4/10 (simplified to 1 2/5).

[tex]1.4=\dfrac{14}{10}=\dfrac{14:2}{10:2}=\dfrac{7}{5}[/tex]

Answer:

(20,5) is NOT a solution of the equation [tex]6x+10y=150[/tex].

The point (20,5) implies that there are 20 small tables and 5 large tables.

Step-by-step explanation:

We have been given that a catering company is expecting 150 people to attend the wedding. There are two types of tables, ones which can fit 6 people and ones which can fit 10 people.

If there are x tables which can fit 6 people and there are y tables which can fit 10 people, we can express the total number of people that can fit on all available tables as: [tex]6x+10y[/tex].

Since there are total 150 people expected in the wedding, the equation can be framed as: [tex]6x+10y=150[/tex].

Let us check if the point (20,5) is a solution of the equation.

[tex]6*20+10*5=150[/tex]

[tex]120+50=150[/tex]

[tex]170=150[/tex]

Since we get a false statement, therefore, (20,5) is NOT a solution of the equation [tex]6x+10y=150[/tex].

The point (20,5) implies that there are 20 small tables and 5 large tables.

To determine if a point is a solution to an equation, substitute the values into the equation. The point (20,5) in the context of a catering company setting up tables represents 20 tables of 6 seats and 5 tables of 10 seats. However, this point is not a solution to the equation 6x + 10y = 150 because substituting these values does not make the equation true.

The point (20,5) in the context of this question represents the numbers of 6-seat and 10-seat tables the catering company needs to set up. To determine if the point (20,5) is a solution to the equation 6x+10y=150, you can substitute the first value of the ordered pair into the equation for x, and the second value for y.

Answer:

The correct option is:   A.  [tex]0=x^2+3x+2[/tex]

Step-by-step explanation:

Quadratic formula:  [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

After substituting the values of a, b and c into the formula, Ramiya's equation is:   [tex]x=\frac{-3\pm\sqrt{3^2-4(1)(2)}}{2(1)}[/tex]

Comparing the above equation with the quadratic formula, we will get........

[tex]2a= 2(1)\\ a=1\\ \\ -b=-3\\ b=3\\ \\ 4ac=4(1)(2)\\ 4(1)c=4(1)(2)\\ c=2[/tex]

The standard form of any quadratic equation is:  [tex]ax^2+bx+c=0[/tex]

So, Ramiya’s quadratic equation will be:  [tex]1x^2+3x+2=0[/tex] or,  [tex]0=x^2+3x+2[/tex]

The Ramya's quadratic equation is 0 = x^2 + 3x + 2 option (A) is correct.

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

The quadratic formula is:

[tex]\rm x=\frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

Ramiya equation is:

[tex]\rm x=\frac{-3\pm \sqrt{3^2-4(1)(2)} }{2(1)}[/tex]

Comparing the Ramiya equation to the quadratic formula, we get:

-b = -3 ⇒ b = 3

2a = 2(1) ⇒ a = 1

4ac = 4(1)(2) ⇒ c = 2

Put these values in the standard equation, we get:

[tex]\rm x^2+3x+2=0[/tex]  or

[tex]0=\rm x^2+3x+2[/tex]

Thus, the Ramya's quadratic equation is 0 = x^2 + 3x + 2 option (A) is correct.

Answer:

Option A is correct.

Step-by-step explanation:

Let the full price of the wallet be represented by = x

Total amount that Nathan paid for the wallet = $17.67

Discount percentage = 5% or 0.05 = 0.05x (5% of full price)

So, equation becomes: full price - discount price = 17.67

[tex]x-0.05x=17.67[/tex]

[tex]0.95x=17.67[/tex]

x = $18.60

Therefore, the full price of the wallet is $18.60.

We can also check this by taking out 5% of 18.60

[tex]0.05\times18.60=0.93[/tex]

And[tex]18.60-0.93=17.67[/tex]

So, option A is correct.

the total bill before taxes and tip is $18.

To calculate the total bill before taxes and tip, we simply need to sum up the costs of the sausage and eggs breakfast and the ham omelet.

Cost of sausage and eggs breakfast = $8

Cost of ham omelet = $10

Total bill before taxes and tip = Cost of sausage and eggs breakfast + Cost of ham omelet

Total bill before taxes and tip = $8 + $10

Total bill before taxes and tip = $18

So, the total bill before taxes and tip is $18.

The probable question maybe:

In a restaurant You order the sausage and eggs breakfast That costs $8, and your friend orders the ham omelet That costs $10. How much is the bill before the taxes and tip?

Answer:(6,-4)

Step-by-step explanation:

6x+7y=4x+4y

If (?,-4)

So we are solving for x. Substitute the y with -4.abd solve.

6x+7(-4)=4x+4(-4)

Multiply 7(-4) on left side and 4(-4) on right side.

6x-28=4x-16

Subtract 4x both sides to get x term on left side

6x-4x-28= -16

Now add 28 to both sides to move to the right side because you want to keep x on left side.

6x-4x=28-16

2x= 28-16

Subtract 28 from 16

2x= 12

Divide 2 to both sides

X=12/2

Solve 12÷2=6

X=6

First, let's calculate the total cost for food. We know that we have 20 people to feed, and it costs $5 to provide food for each person. Therefore, we multiply the number of people by the cost per person to get the total cost for food. That would be:

20 people * $5/person = $100

So, the total cost for food is $100.

Next, let's calculate the total cost for the games. We're assuming that each person is playing x number of games, and that each game costs $1 to play. Therefore, we multiply the number of people by the cost per game and the number of games each person plays to find the total cost for games:

20 people * $1/game * x games = $20x

So, the total cost for the games depends on the number of games that each person plays.

If we want to find out the total cost of the party, we need to add the total cost for food and the total cost for games. This can be represented as:

$100 + $20x

This means the total cost of the party will be $100 plus $20 times the number of games each person plays. The exact total cost will depend on the value of x, i.e., the number of games each person plays.

$37,500 profit

To solve this, find the unit rate by dividing 2500 by 20. This will get you an average of $125 profit made per product sold. Then multiply that by 300 (the number of products sold in total) to get your answer of $37,500 profit total.

Answer:

Assuming that the profit is the same for each sale, the amount they make is 37,500

Step-by-step explanation:

In order to find this, we set up a proportion using those numbers.

2500/20 = x/300 ----> Cross multiply

20*x = 2500*300 ----> Multiply

20x = 750,000 ----> Divide by 20

x = 37,500

D = c-s/n

Dn = n(c-s/n)

Dn = c - s

Dn + s = c

c = Dn +s

To solve for c in the equation D=c-s/n, isolate c by multiplying both sides by n, then rearrange the terms and divide by (n-D).

To solve for c in the equation D=c-s/n, we need to isolate c. We can start by multiplying both sides of the equation by n to eliminate the fraction:

nD=cn-(s/n)(n)

Simplifying further, we get:

nD=cn-s

Next, we can bring the term cn to the left side of the equation by subtracting cn from both sides:

nD-cn=-(cn-s)

Rearranging the terms, we have:

-cn+nD=-(cn-s)

Factoring out c from the left side, we get:

c(n-D)=cn-s

Finally, we can solve for c by dividing both sides of the equation by (n-D):

c=(cn-s)/(n-D)
