Mellisa buys 2.5 pounds of salmon and 1.25 pounds of swordfish. She pays a total of $31.25, and the swordfish costs $0.20 per pound less than the salmon l. What would be the combined cost of 1 pound of salmon and 1 pound of swordfish.

Answers

Answer 1

The combined cost of 1 pound of salmon and 1 pound of swordfish is $16.60

Let $x be the cost of 1 pound of salmon.

The swordfish costs $0.20 per pound less than the salmon, then $(x-0.20) is the cost of 1 pound of swordfish.

Melissa buys 2.5 pounds of salmon and pays $2.5x for salmon.

Melissa buys 1.25 pounds of swordfish and pays $1.25(x-0.20) for swordfish.

She pays a total of $31.25, then we get an equation,

2.5x + 1.25(x - 0.20) = 31.25

We solve above equation for x.

2.5x + 1.25x - 0.25 = 31.25

3.75x = 31.50

x = 8.4

So, the cost of 1 pound of salmon is $8.40 and 1 pound of swordfish is $8.20

and combined cost = $8.40 + $8.20

Therefore, the combined cost of 1 pound of salmon and 1 pound of swordfish is $16.60

The equation of the parallel line is….

Answers

The equation of the parallel line is y = x + 2.

What is Equation of line?

The equation of line with slope m and y intercept at point b is given as;

y = mx + b

Given that;

The point = C(4, 6)

And, equation of line is y = x + 7

Since, Slope of Parallel lines are always same.

So, The slope of the given line is calculated as;

y = x + 7

m = dy/dx = 1

Thus, Slope of parallel lines is 1.

Since, The equation of line is passes through point C (4, 6).

So, The equation of line with slope(m) 1 and point C(4, 6) is;

y - 6 = 1 (x - 4)

y - 6 = x - 4

y = x - 4 + 6

y = x + 2

Thus, The equation of the parallel line is y = x + 2.

Answers

The greatest of the 4 consecutive integers with a sum of -278 is -68

Let n, n + 1, n + 2 and n + 3 be four consecutive integers.

The sum of four consecutive integers is -278.

⇒ n + (n + 1) + (n + 2) + (n + 3) = -278

⇒ n + n + n + n + 1 + 2 + 3 = -278

⇒ 4n + 6 = -278

⇒ 4n = -278 - 6

⇒ 4n = -284

⇒ n = -284/4

⇒ n = -71

So, the consecutive integers would would be:

n = -71

n + 1 = -70

n + 2 = -69

which measurements are equivalent to 3 yards

Answers

The equivalent measures to 3 yards are;

108 inches and ; 6 ft 36 inches

Here, we want to get the values of the measurements that are equivalent to 3 yards

To do this, we need to know how to convert between the various measure types

We proceed as follows;

Mathematically, 1 yard is 36 inches; also, 1 yard is 3 feet

So, 3 yards is (3*36) = 108 inches

Also, 3 yards is (3*3) = 9 feet

Also, 1 ft is 12 inches;

So, 6 ft 12 inches is 7 feet

108 inches is as seen above, so 3 yards equal this

3 yards is not 108 feet as calculated above

6 ft 36 inches

36 inches is 3 ft; so by addition; 6 ft 36 inches is 9 ft

So, the correct answers here are 108 inches and 6 ft 36 inches

Which 3 measurements could be the dimensions of a right triangle?
(a² + b² = c²)

Answers

Answer:

5, 12, 13

Step-by-step explanation:

let a = 5 , b = 12 , c = 13 , then

5² + 12² = 25 + 144 = 169

13² = 169

so a² + b² = c²

Answer:

3, 4, 5

Step-by-step explanation:

In a right triangle, we have 2 legs and a hypotenuse. The hypotenuse equals c, while the other 2 legs are a and b.

Lets say a = 3, b = 4, and c = 5

The formula is a² + b² = c²

3² + 4² = 5²

9 + 16 = 25

25 = 25

Therefore, 3, 4, and 5 can be dimensions of a right triangle.

Distance between M(6,-7) and a line that contains the points C(-6,-2) and H(-1,10) is 7.846

First we will find the equation of the line containing the points C(-6,-2) and H(-1,10).

Take (x₁, y₁) = (-6,-2) and (x₂, y₂) = (-1,10).

Then the slope of the line, m = y₂-y₁/x₂-x₁

                                           = 10- -2/-1- -6

                                           = -12/7

So the equation of the line is

y-y₁ = m(x-x₁)

⇒ y- -2 = -12/7(x- -6)

⇒ y+2 = -12/7(x+6)

⇒7(y+2) = -12(x+6)

⇒ 7y +14 = -12x -72

⇒ 12x+7y +14+72 = 0

⇒ 12x+7y+86 = 0

This is in the form ax+ by+ c = 0

Also given the point (x, y) = (6, -7).

Distance between a point (x, y) and a line ax+ by+ c = 0 is,

[tex]\frac{|ax+by+c|}{\sqrt{a^2+b^2} }[/tex].

So Distance between M(6,-7)  and the line 12x+7y+86 = 0 is

[tex]\frac{|12.6+7.-7+86|}{\sqrt{12^2+7^2} }[/tex] = |72-49+86|/√(144+49)

                    = 109/√193

Anya plays one round of her favorite online game every day. One week, she played 7 rounds and scored between 120 and 300 points each round. She calculated the mean and median of those scores.
Then, Anya found out that the day she scored 300 points was a special "double points" day, so she actually earned 600 points, not 300.
How will this amount increasing affect the mean and median?

Answers

Answer:

D: The mean will increase, and the median will stay the same.

Step-by-step explanation:

Strategy

The mean and median are two ways to describe the center of a data set.

When a data set is almost symmetrical, the mean and median are close together.

When a data set is not symmetrical, the mean is usually closer to the outliers or tail than the median.

Let's reason conceptually about the measures of the center since we do not know the exact values.

Reasoning about the median

There are 7 scores. When the scores are in order from least to greatest, the median is the 4th score.

The day when Anya scored 300 points was the largest score both before and after that score was increased. So that is the 7th score when we order them from least to greatest.

Changing the 7th score does not change the 4th score, so the median stays the same.

Reasoning about the mean

Let's remember how to calculate the mean:

mean = total points/number of rounds

The largest score increasing from 300 to 600 points increases the total number of points. However, it does not change the number of rounds. So the mean increases.

Conclusion

D: The mean will increase, and the median will stay the same.

Answer:

x = -262/13, y = -5/13, z = 89/13

Step-by-step explanation:

Solve the following system:

{3 z + 4 y = 19 | (equation 1)

z - x = 27 | (equation 2)

-3 y + x = -19 | (equation 3)

Swap equation 1 with equation 2:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

x - 3 y + 0 z = -19 | (equation 3)

Add equation 1 to equation 3:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x - 3 y + z = 8 | (equation 3)

Add 3/4 × (equation 2) to equation 3:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x + 0 y + (13 z)/4 = 89/4 | (equation 3)

Multiply equation 3 by 4:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x + 0 y + 13 z = 89 | (equation 3)

Divide equation 3 by 13:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 3 z = 19 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Subtract 3 × (equation 3) from equation 2:

{-x + 0 y + z = 27 | (equation 1)

0 x + 4 y + 0 z = -20/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Divide equation 2 by 4:

{-x + 0 y + z = 27 | (equation 1)

0 x + y + 0 z = -5/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Subtract equation 3 from equation 1:

{-x + 0 y + 0 z = 262/13 | (equation 1)

0 x + y + 0 z = -5/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Multiply equation 1 by -1:

{x + 0 y + 0 z = -262/13 | (equation 1)

0 x + y + 0 z = -5/13 | (equation 2)

0 x + 0 y + z = 89/13 | (equation 3)

Collect results:

Answers

If Jenny studies one hour both for economics and history she can gain 10+15=25 points

What is meant by Increasing?

Increasing: Growing larger or greater. Therefore, if the derivative of a function is positive, then the function is increasing. Let's consider our example of g(x) = x2. The derivative of g(x) = x2 is g'(x) = 2x. Since we are multiplying x by the positive number 2, it's easy to see that g ' is positive when x is positive and negative when x is negative.

Jenny will receive 15 points if she simply studies economics, which equates to 10 points in the first hour and 5 points in the second.

Jenny will earn 20 points if she exclusively studies history, which equates to 15 points in the first class and 5 points in the second.

Jenny should study economics for one hour, which will get her 10 points, and history for one hour, which will gain her 15 points, for a total of 25 points in the two hours

So we concluded that if Jenny studies one hour both for economics and history she can gain 10+15=25 points
