Dory and Nemo go to Taco Bell for lunch. Dory orders three soft tacos and three double deckers for 11.25. Nemo pays $10 for four soft tacos and two double deckers. Write a system of equations that represents the lunch orders for dory and Nemo.

Answers

Answer 1
Soft tacos = x
double deckers = y

Dory
3x + 3y and the total was 11.25
11.25 = 3x + 3y

Nemo
4x + 2y and the total was 10
10 = 4x + 2y

The equations are 
11.25 = 3x + 3y
10 = 4x + 2y

Hope this helps

Answer 2

The equations representing Dory's and Nemo's lunch orders are 3x + 3y = 11.25 and 4x + 2y = 10, respectively.

Let's define the variables first. Let x be the cost of one soft taco, and y be the cost of one double decker.

Dory orders three soft tacos and three double deckers for $11.25. This gives us the first equation:

3x + 3y = 11.25

Nemo orders four soft tacos and two double deckers for $10. This gives us the second equation:

4x + 2y = 10

We now have a system of equations that represents the lunch orders:

3x + 3y = 11.25

4x + 2y = 10

These equations can be solved simultaneously to find the individual costs of the soft tacos and double deckers.

Write an equation in point-slope form of the line having the given slope that contains the given point. m=56m=56m (30,12)

Answers

Point-slope form is [tex]y-y_1=m(x-x_1)[/tex], where the point [tex]P(x_1,y_1)[/tex] lies on the graph and m is the slope of the graph.

We have a point (30, 12) and a slope of 56.

So we write [tex]y-12=56(x-30)[/tex]. And we're done.

In which of the following cases would you most likely buy a point when closing on a home loan?

Answers

Just took the test its d.The monthly payment is reduced by $14 and you plan to sell the home at the end of 7 years. 

Final answer:

Buying a point during a home loan closing is most likely to make sense if interest rates have fallen, you plan to stay in the home long term, and you have ample cash for upfront costs, as this could result in significant savings over the life of the loan.

Explanation:

When considering the question of whether you would most likely buy a point when closing on a home loan, the main factors to consider are the interest rates and the duration for which you plan to hold the loan. Buying a point refers to paying an upfront fee to lower your mortgage interest rate, which is attractive if you plan to stay in the home for a long period, as the savings on interest payments could outweigh the initial cost. You would be more inclined to buy a point if:

Interest rates in the economy have fallen, and you want to lock in a lower rate for the duration of your loan.

The available cash for upfront costs is sufficient to cover the cost of buying points without detrimentally impacting other financial commitments.

The assessment is that staying in the property for a long duration will allow for greater cumulated savings due to the reduced interest payments over time.

These scenarios are more likely to justify the transaction costs of purchasing a home with an upfront payment to buy points, thus securing a lower interest rate for the mortgage.

Answer:

1800 pictures could fit on the wall.

Step-by-step explanation:

If the area of a space is given as A and this space is to be filled by pictures of area A' then number of pictures will be = [tex]\frac{A}{A'}[/tex]

Now we know area of wall is A and area of picture is A'.

Length and width of wall = 3.6×1.8 m

So area of the wall A = 3.6×1.8 = 6.48 m²

Dimensions of one picture = 6×6 cm Or 0.06×0.06 m

So are of one picture A' = 0.0036 m²

Therefore, Number of pictures on the wall = [tex]\frac{A}{A'}[/tex] = [tex]\frac{6.48}{0.0036}=1800[/tex]

Number of pictures required to cover the wall = 1800

Find the probability that the student is male or a nursing major.

Answers

the correct question is
The table below shows the number of male and female students enrolled in nursing at a particular university for a recent semester. ​(a) y Find the probability that a randomly selected student is male or a nursing major.

see the attached table

a) the probability that a randomly selected student is​ male, or a nursing major
total students=[1151+2409]=3560
total male=[98+1053]=1151
P (selected student is​ male)=1151/3560=0.3233
total nursing mayor=[98+741]=839
P (selected student is​ nursing major)=839/3560=0.2357
P(selected student is​ male, or a nursing major)=0.3233+0.2357=0.5590

the answer is 0.5590  (55.90%)


Final answer:

The probability that a student is male or a nursing major is expressed by the formula P(M OR N) = P(M) + P(N) - P(M AND N), which requires actual data to calculate.

Explanation:

To find the probability that a student is male or a nursing major, we can use the principle of addition in probabilities. Let's denote P(M) as the probability that a student is male, P(N) as the probability that a student is a nursing major, and P(M AND N) as the probability that a student is both male and a nursing major. The formula for the probability of either event occurring is given by P(M OR N) = P(M) + P(N) - P(M AND N). We need actual data to calculate these probabilities.

Since we don't have the actual probabilities, we can only provide the symbolic representation of the required probability as P(M OR N). However, if the events of being male and majoring in nursing are mutually exclusive (which in reality, they are not), the probability would simplify to just the sum of the two individual probabilities, P(M) + P(N).

You sell bracelets for $2 each and necklaces for $3 each at a local flea market. You collect. $95, selling a total of 37 jewelry items. How many of each type of jewelry did you sell?

Answers

16 bracelets. 21 necklaces.
Write a system of equation based on the problem
For an instance, b stands for the number of bracelets, n stands for the number of necklaces.
⇒ Total collected money is $95, $2 per bracelet, $3 per necklace
     2b + 3n = 95  (first equation)
⇒ 37 jewelry items have been sold
    b + n = 37

Find the number of necklaces (n) by eliminating the number of bracelets (b) from the equation system
2b + 3n = 95
  b +   n = 37     (multiply by 2)
----------------------------------------
2b + 3n = 95
2b + 2n = 74
---------------- - (substract)
          n = 21

Find the number of bracelets by substituting the value of n to either of the equations
b + n = 37
b + 21 = 37
b = 37 - 21
b = 16

Type of jewelry have been sold: 16 bracelets, 21 necklaces

Denise and Stacey went to a carnival. The admission fee was $6 per person. Each ride at the carnival costs c dollars. The game booths charged g dollars for each game. Both Denise and Stacey went on 7 rides each. Stacey played 3 games, while Denise played 2 games. Which expression represents the total amount of money that Denise and Stacey spent at the carnival? 7c + 5g + 6 7c + 5g + 12 14c + 5g + 6 14c + 5g + 12

Answers

Let's first have a look at the admission fee, which is $6,- per person. 
This makes a total of $12,-
(Since 6 x 2 = 12).

Next up, the ride at the carnival. This costs c dollars.
This makes a total of 14c
(Since they have made a total of 14 rides (7 each), and we multiply it by 'c')

Finally the game boots, which costs g dollars a game.
Denise and Stacey played a total of 5 games, hence the total cost of the boots will be 5g.

The total cost will therefore be: 14c + 5g + 12
This makes the fourth answer (in your question) the correct answer.

The correct answer is D. 14c + 5g + 12.

The entry fee is $6 each. 6 + 6 = 12

Each girl goes on 7 rides which cost c dollars. 7c + 7c = 14c

The number of games both girls play totals 5. And each game costs g dollars. 2g + 3g = 5g.

Add all the costs up and you get 14c + 5g + 12 as their total cost for going to a carnival.

A certain human red blood cell has a diameter of 0.000007 meters. Write an expression that represents this diameter, in meters in scientific notation.

Answers

7 x 10^-6 You're basically just moving the decimal place over six times until there is a whole number before the decimal.
 

Given is the diameter of a human red blood cell equal to 0.000007 meters. It says to convert and rewrite this measurement in meters in scientific notation.

A scientific notation is written as product of a significant number and exponent of 10's. To find significant number from given 0.000007, we must move decimal point in either right or left direction such that it becomes integral value and in addition we would multiply some exponent of 10's to make its value equivalent to given 0.000007 meters.

Re-writing in scientific notation :-

0.000007 meters

= [tex] \frac{7}{1000000} \;meters [/tex]

= [tex] \frac{7}{10^{6}} \;meters [/tex]

[tex] =7*10^{-6} \;meters [/tex]

So, final answer is 7 x 10⁻⁶ meters.
