Can anyone help me with this please?

Answer:

Low cost will result in more supply and low customer demands as demands decrease this will result in increase of supply,so low unit cost will is better value only if you purchased all the items to get lower unit rate.

Unit rates are the rates of one quantity.

Paul's claim about unit rates is correct.

From the question, we understand that Paul's claim that lower unit rates are better.

Take for instance, the following unit rates of a computer device in two stores are:

[tex]Rate\ 1 = \$50/computer[/tex]

[tex]Rate\ 2 = \$55/computer[/tex]

The sales of two computers in both stores would cost

[tex]Store\ 1 = \$100[/tex]

[tex]Store\ 2 = \$110[/tex]

By comparison, the cost of 2 computer devices in store 1 costs lesser because store 1 uses a lesser unit rates.

Hence, Paul's claim about unit rates is correct.

Step-by-step explanation:

just put one part of the equation in y1 and the other in y2 and hit 2nd trace 5 an hit enter 4 times

then it will bring a graph hit enter 3 time again and it will show u the answer at the bottom left

The solution to the equation 3a-7(3-a)=5 is a=13/5.

Let's solve for a in the equation:

3a-7(3-a)=5

We can solve the equation by rearranging the terms, distributing, combining like terms, adding/subtracting to both sides, dividing both sides by the same factor, and simplifying.

Steps to solve:

Rearrange terms:

3a-7(-a+3)=5

Distribute:

3a+7a-21=5

Combine like terms:

10a-21=5

Add/subtract to both sides:

10a-21+21=5+21

Simplify:

10a=26

Divide both sides by the same factor:

10a/10=26/10

Answer:

317

Step-by-step explanation:

Since the ratio is 1:232, multiply 232 by 16.4:

[tex]232*16.4=d[/tex]

[tex]d=3804.8 in[/tex]

Divide by 12 to find the feet

[tex]3804.8[/tex]÷[tex]12=d[/tex]

[tex]d=317.066[/tex]

Round to the nearest foot

[tex]d=317[/tex]

Final answer:

To find the actual stadium distance from home plate to left field, convert 16.4 inches to feet and then multiply by the scale factor of 232, resulting in approximately 317 feet.

Explanation:

The student is asking how to convert a scale model measurement to the actual size measurement. Given the scale of 1:232 and the model's distance from home plate to left field as 16.4 inches, we can find the actual stadium distance by multiplying the model measurement by the scale factor.

First, convert inches to feet: 16.4 inches × (1 foot / 12 inches) = 1.3666667 feet (rounded to seven decimal places).

Then multiply by the scale factor to get the distance in the actual stadium: 1.3666667 feet × 232 = 317.0666674 feet, which we round to 317 feet to the nearest foot.

Therefore, the distance from home plate to left field in the actual stadium is approximately 317 feet.

Answer: 2/3x-13/12=-5/12x

Step-by-step explanation:

The equivalent equation is (8x + 5x)/12 = (3 + 10)/12 and x = 1.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

(2/3)x - 5/6 = -(5/12)x + 1/4

Add like terms.

(2/3)x + (5/12)x = 1/4 + 5/6

(8x + 5x)/12 = (3 + 10)/12

13x / 12 = 13/12

x = 1

Thus,

x = 1

Answer: The value of the investment would be $4,075

Step-by-step explanation: The initial investment, that is, the principal is given as $2500, and it was invested for a period of 10 years at the rate of 6.3%. Using the simple interest calculation formula, the investment would have a present value as follows;

Interest = P x R x T

Where P = amount invested (2500), R = rate of interest (6.3 or 0.063) and T = number of years (10)

Interest = 2500 x 0.063 x 10

Interest = 1575

The value of the investment at 6.3% after 10 years is now;

Initial investment + Interest

2500 + 1575 = 4075

Therefore the value of the investment is $4,075

Final answer:

The area of a larger square with side lengths twice that of a smaller square is four times greater. This is because the scale factor for areas is the square of the scale factor for lengths, leading to an area of 64 square inches for the larger square, compared to 16 square inches for the smaller one.

Explanation:

When Marta has a square with a side length of 4 inches and then creates a similar square with dimensions that are twice the first square, we are working with a scale factor in geometry. As the new square has side lengths that are twice that of the original square (4 inches x 2 = 8 inches), the area of the larger square will be greater than that of the smaller square. To find the area of the larger square, we square the side length (8 inches x 8 inches), which gives us 64 square inches. This is exactly four times the area of the first square (4 inches x 4 inches = 16 square inches), since the scale factor for the areas of similar figures is the square of the scale factor for their corresponding lengths.

In the context of the examples given, this principle applies to understanding how the area of shapes scales when their dimensions are proportionally increased or decreased. The scale factor can be used to calculate dimensions or area of similar figures in various geometric problems.

In a 30 60 90 triangle as shown here a is always 1/2 the hypotenuse (Which the hypotenuse is 6) and then just add [tex]\sqrt{3}[/tex] to the end of it to get b

So, lets demonstrate

a = 1/2 * 6 = 3

b = a*[tex]\sqrt{3}[/tex] = a[tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]

So,

a = 3

b = 3[tex]\sqrt{3}[/tex]

Answer:

Step-by-step explanation:

Area of the shaded region =[ (3x-2)(x+3) ] - [ x*6 ]

= 3x*x +3x*3 + (-2)*x  + (-2)*3 - 6x

=3x² + 9x - 2x - 6 - 6x      {bring like term together}

=3x² + 9x - 2x - 6x - 6

= 3x² + x - 6           {9x - 2x - 6x = 9x - 8x = x}

Area = 24 square units

3x² + x - 6 = 24

3x² + x - 6 - 24 = 0

3x² + x - 30 = 0

Product = 3* -30 = -90

Sum = 1

Factors = 10 , (-1)

3x² + x - 30 = 0

3x² - 9x + 10x - 10*3 = 0

3x*(x - 3) +10*(x - 3) = 0

(x-3)(3x +10) = 0

3x + 10 is ignored because measurements will not be in negative values.

x - 3 = 0

Step-by-step explanation:

In any circle the ratio of the arc length to the circumference of the circle is equal to the degree measure of the arc to 360°

Answer:

[tex]\dfrac{\pi}{2} cm[/tex]

Step-by-step explanation:

Given two concentric circles where:

Length of the intercepted arc for a central angle of [tex]\dfrac{\pi}{2} =\dfrac{\frac{\pi}{2} }{2\pi} X2\pi r=\dfrac{\pi r}{2}[/tex]

For the larger circle of radius 5cm, Length of the intercepted arc[tex]=\dfrac{5\pi}{2}[/tex]

For the smaller circle of radius 4cm, Length of the intercepted arc[tex]=\dfrac{4\pi}{2}[/tex]

Difference in Arc length

[tex]=\dfrac{5\pi}{2}-\dfrac{4\pi}{2}\\=\dfrac{\pi}{2} cm[/tex]

The difference in arc lengths between the two concentric circles for a central angle of π/2 radians is approximately 1.57 cm.

To compare the lengths of arcs intercepted by the same central angle in two concentric circles, we use the formula for arc length, which in a circle is a portion of its circumference that corresponds to the central angle. For a central angle π/2 radians, the arc length is given by (rθ), where r is the radius of the circle and θ is the central angle in radians.

For the smaller circle, the arc length is 4 cm × π/2 = 2π cm, and for the larger circle, it is 5 cm × π/2 = 2.5π cm. The difference in arc lengths is 2.5π cm - 2π cm = 0.5π cm. Using the approximate value of π as 3.14159, the difference in arc lengths is approximately 1.57 cm.

Let x represent number of hours after noon.

We have been given that Sara starts at noon and walks at a speed of 4 miles per hour. So distance covered by Sara in x hours would be [tex]4x[/tex].

We are also told that Eddie leaves the  same place an hour later. This means that Sara will be 4 miles ahead of Eddie as Sara will travel 4 miles in 1 hour.

As Eddie walks in the same direction at a speed of 5  miles per hour. So distance covered by Eddie in x hours would be [tex]5x[/tex].

Total distance covered by Sara when Eddie will start would be [tex]4x+4[/tex].

Now we will equate distance covered by both in x hours as:

[tex]5x=4x+4[/tex]

Let us solve for x.

[tex]5x-4x=4x-4x+4[/tex]

[tex]x=4[/tex]

Since x represents number of hours after noon, so 4 represents 4 hours after noon.

Therefore, Eddie will catch up with Sara at 4:00 pm and option D is the correct choice.

Step-by-step explanation:

The area of the composite figure to the nearest whole number is 13 ft².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Given:

Radius= 2 feet

As, Area of a single Quadrant = πr²/4

and, For 3 semi circle

= πr²/4 + πr²/4 + πr²/4 or 3 (πr²/4)

= 3 x 3.14 x 2 x 2 /4

= 9.42 ft²

and, Area of Square

= s x s

= 2 x 2

= 4 ft²

So, the Area of Figure = 4 + 9.42 = 13.42 ft²
