Answer:

An apple costs 0.30 pounds and a banana costs 0.40 pounds.

Step-by-step explanation:

Let's think of apples as x and bananas as y.

Using the given information, you can write two equations.

[tex]x+6y=2.70[/tex]

[tex]x+8y=3.50[/tex]

x can also be written as

[tex]x=2.70-6y[/tex]

We can plug this equation into the second one to solve for y, or the cost of a banana.

[tex](2.70-6y)+8y=3.50[/tex]

[tex]2y=0.8[/tex]

[tex]y=0.4[/tex]

Now that we know the cost of a banana, we can go back to the first equation and solve for x, or the cost of an apple.

[tex]x+6(0.4)=2.70[/tex]

[tex]x=0.30[/tex]

Therefore, an apple costs 0.30 pounds and a banana costs 0.40 pounds.

The width of the bumper sticker is 6 1/4 inches .

In order to determine the width of the bumper sticker, the first step is to determine the relationship between the height of the design and that of the bumper sticker.

The relationship can be determined by dividing the height of the bumper sticker by the height of the design.

Proportion of the heights = 3 1/2 ÷ 2

5/2 ÷ 2

= 5/2 x 1/2 = 5/4 = 1 1/4

Now, multiply the proportion of the heights by the width of the design :

Width of the design = 1 1/4 x 5

5/4 x 5/1 = 25/4 = 6 1/4 inches

The number of hours to breakeven will be 5 hiurs

The breakeven is the point at which the cost and the revenue are equal.

Since Mitch sells thingamabobs. His revenue is modeled by the function R(h) = 5h+ + 8 for every h hours he spends working and his overhead cost is modeled by the function C'′(h) = h² + 7h − 16.

This wll be:

Revenue = Cost

5h + 8 = h² + 7h - 16

Collect like terms

h² + 7h - 5h - 16 = 0

h² - 2h - 16 = 0

Solving the equation will give h as 5.

The number of hours will be 5 hours.

The total maximum area enclosed by both the shapes square and a circle using given wire is equal to 2.27 square feet.

As given in the question,

Let 'x' be the side length of the square

And 'r' be the radius of the circle.

Length of the wire = 4 feet

Maximum side length of the square is:

4x = 4

⇒ x = 1feet

Maximum area of the square = x²

                                                = 1²

                                                = 1

Maximum radius of the circle is:

2πr = 4

⇒ r = 2 / π

Maximum area of the circle = πr²

                                              = π × (2/π)²

                                              = 4 / π

Total maximum area enclosed by square and a circle

= 1 + (4/π)

= 1 + 1.27

= 2.27 square feet.

Therefore, the total maximum area enclosed by square and a circle from the given wire is equal to 2.27 square feet.

The value of x in the trapezium is 60 degrees.

A trapezium is a quadrilateral . The sum of angles in the trapezium is 360 degrees. The legs of the trapezium ABCD are congruent.

The length AB and CD are parallel to each other.

Let's find the angle x as follows:

Therefore, using trigonometric ratios,

cos x = adjacent / hypotenuse

Where

adjacent side = 3 m

hypotenuse side = 6 m

Hence,

cos x = 3 / 6

cos x = 1 / 2

x = cos ⁻¹ 0.5

x = 60 degrees

The equation of the line that passes through the point (-4,-4) is y=-x-8.

The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y -axis).

The three equation of line are slope-intercept form, standard form and point-intercept form.

4x+4y=-28

Taking 4 common and dividing both sides by 4 gives

x+y= -7

y=-x-7

This means slope that is m=-1.

Now to find c in y=mx+c we need to use points (-4,-4).

Answer:

post cards cost .06 each and envelopes cost .08 each.

Step-by-step explanation:

Let p = the cost of the post cards

Let e = the cost of the envelopes

15p + 10e = 1.70

e = p + .02  Substitute  p + .02 for e in the first equation

15p + 10(p + .02) = 1.70   Distribute the 10

15p + 10p + .2 = 1.70     Combine like terms

25p + .2 = 1.70  Subtract .2 from both sides

25p = 1.50  Divide both sides by 25

p = .06

Post cards cost .06 each.

Envelopes cost .08 each

The equations have no solutions and run parallel to one another. The pair of linear equations is hence inconsistent.

Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

The definition of linear equations, the standard form for linear equations involving one variable, two variables, or three variables, and examples of each will all be covered in detail in this article.

Find the value of the variable that causes the equation to be true in order to solve linear equations.

Utilize the inverse of the variable's multiplier and divide or multiply both sides by it.

To obtain the variable value, simplify the result. Put your solution back into the equation to verify it.

So, we have the pair of linear equations:

x – y = 8 and 3x – 3y = 16

(a1/a2) = 1/3

(b1/b2) = -1/-3 = 1/3

(c1/c2) = 8/16 = 1/2

Since, we know that (a1/a2) = (b1/b2) ≠ (c1/c2).

The equations have no solutions and run parallel to one another. The pair of linear equations is hence incoherent.

The reason that objective tests include so many items is to increase the reliability of the test.

Reliability Test

It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores. Scores that are highly reliable are precise, reproducible, and consistent from one testing occasion to another.

Probability

A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.

A measure of reliability between two variants of the same test is known as alternate forms reliability. The results of two identical (but distinct) tests are correlated, and a reliability coefficient is computed. If variations in one test's observed results correspond to variations in the scores of an equivalent test, the test is said to be dependable. A psychological test's practise effect which is typical of test-retest reliability, can be mitigated by a survey instrument's alternate-form reliability. The goal is to reword the survey questions in a way that makes them functionally identical, or just rearrange the questions in the first and second surveys of the same respondents.

According to the equation model V=P(1-r)^t, the approximate value of Doug's car after 4¹/₂ years is $9,200.

The equation is a mathematical statement or model that shows that two mathematical expressions are equal.

In this situation, the mathematical expressions equal to each other are V, the car's depreciated value, and P(1-r)^t, which combines variables.

Cost of the new car = $25,000

Depreciation rate per annum = 20%

Value of the car = V

The price paid initially = P = $25,000

The annual rate of depreciation = r

Depreciation period = 4¹/₂ years

Equation model: V=P(1-r)^t

Depreciated value after 4 1/2 years, V = $25,000 (1 - 0.2)^4¹/₂

= $9,158.93

= $9,200

 Third or upper quartile, or 75th percentile, is another name for this group. The figure at which 25% of the responses are higher and 75% of the answers are lower is known as the 75th percentile.

A suitable compromise between representing the great majority of measures and being unaffected by outliers is the 75th percentile. The 75th percentile is a suitable choice for identifying medium- to long-term trends even if it is less steady than the median. Additionally, we believe that when establishing performance budgets, the 75th percentile is the ideal figure to employ.  Although the term "percentile" is frequently used, it lacks a common definition. The most typical definition of a percentile is a number below which a predetermined proportion of scores fall. You may already be aware of your test score of 67 out of 90.
