The disadvantage of using cash as a payment method is the requirement to hand deliver all payments. This method is less convenient and secure compared to electronic payments, highlighting the shift towards a cashless society.

The question asked is, "Which is a disadvantage of using cash as a payment method?" The correct answer to this question is that one must hand deliver all payments when using cash. This is a significant disadvantage compared to electronic forms of payment. In our increasingly digital world, methods like credit cards, online banking, and mobile payment platforms like Apple Pay introduced in 2014 offer the convenience of making payments from virtually anywhere without the need to physically handle currency.

This shift towards a cashless society highlights the limitations of cash transactions, especially in terms of convenience and security. Moreover, in scenarios such as paying bills, shopping for large purchases, or conducting business transactions, the logistical challenges of using cash become even more apparent. Electronic payments, on the other hand, allow for easier transaction tracking and less physical risk, making them more appealing for both consumers and businesses.

Answer: There are 184 total number of CDs they own.

Step-by-step explanation:

Since we have given that

Ratio of rock music to total CDs that Ella Owens is

[tex]15:40\\\\=3:8[/tex]

Step-by-step explanation:

Since the triangle is equilateral, all the sides have the same measures.

You can set any two sides equal to each other, and solve for x.

4x-30 = 2x + 20

4x  = 2x + 50                add 30 to both sides

2x = 50                         subtract 2x from both sides

x = 25                            divide both sides by 2

You can plug x into the expressions and compare the sides to make sure its correct.

Answer: Option 'C' is correct.

Step-by-step explanation:

We need to find which has one dimension.

Since Point is undefined term with no size or dimension, but in two dimensional it is found in ordered pair i.e. (x,y)

Plane is also an undefined term with length and width but no thickness, so,  it is two dimensional.

Angle is undefined term formed by tow lines or rays diverging from a common vertex, so it is two-dimensional.

But Line is also undefined term with length only but there is no width or thickness.

So, Line has exactly one dimension.

Hence, Option 'C' is correct.

Hope this helps!

--Emilie Xx

By using the percentage given, we can calculate that there are 24 water-related rides at the amusement park out of the total 80 rides.

The question is asking how many of the total rides at the amusement park are water-related. This is a problem related to percentage. We know that 30% of the park's 80 rides are water-related. To find out the exact number, we multiply the total number of rides (80) by the percentage of water rides (30%), but since percentage is in terms of 100, we first convert the 30% to a decimal by dividing it by 100. This gives us 0.30. We then multiply 80 (the total number of rides) by 0.30.

Here's the calculation: 80 rides * 0.30 = 24 rides.

So, there are 24 water-related rides at the amusement park.

Answer:Sample Response: The points are on a horizontal line, parallel to the x-axis. The absolute value of −3 represents the distance from (−3, −5) to the y-axis, and the absolute value of 9 represents the distance from the y-axis to (9, −5).

Step-by-step explanation:

|-3| + |9| represents the distance between the points (-3,-5) and (9,-5) because the two points form a horizontal line

The line passes through the points (-3,-5) and (9,-5)

That is, [tex]x_1=-3, y_1=-5, x_2=9, y_2=-5[/tex]

Since [tex]y_1=y_2=-5[/tex], the line is a horizontal line

For a horizontal line passing though the points [tex](x_1, y_1)[/tex] and [tex](x_2, y_1)[/tex], the distance(D) between the two points is given as:

[tex]D=|x_1|+|x_2|\\\\ D=|-3|+|9|[/tex]

The degree of the polynomial is 4.

To determine the degree of a polynomial, we look for the highest power of the variable present in any of its terms. Let's break down the given polynomial and identify the terms:

[tex]\[ -3.1ax^4 + 2.5ax + 2ax^4 + 1.1ax^4 - 0.5ax - 2ax \][/tex]

Here, we have terms with different powers of [tex]\( x \): \( x^4 \), \( x \),[/tex] and constant terms.

Combine like terms:

[tex]\[ (-3.1a + 2 + 2.1 + 1.1 - 0.5 - 2)ax^4 \][/tex]

[tex]\[ = (-3.1a + 2 + 2.1 + 1.1 - 0.5 - 2)ax^4 \][/tex]

[tex]\[ = (-0.4a)ax^4 \][/tex]

Now, let's analyze the combined term [tex]\( (-0.4a)ax^4 \)[/tex].

The highest power of ( x ) in this term is 4. So, the degree of the polynomial is 4.

Therefore, the degree of the polynomial is 4.

Answer:

Area of the base = [tex]2x^2+5x-18[/tex]

Step-by-step explanation:

We know that volume of rectangular prism = (Area of base) x (Height)

or [Area of base] = [Volume]/[Height]

So basically we need to divide given area by given height to find the answer.

given height is (x+2) that means (x+2) must be factor of volume equation

or x=-2 must be root of volume equation so write down coefficients of volume equation then we divide by -2 as shown in attached picture.

Last digit on the right is always remainder.

Remaining coefficients {2, 5, -18} will give the area equation: [tex]2x^2+5x-18[/tex]

Hence final answer is:

Area of the base = [tex]2x^2+5x-18[/tex]

Answer:9 is the only one

Step-by-step explanation:

Answer:

The number of bricks is 16 and the number of blocks is 12

Step-by-step explanation:

Let the number of bricks be x and blocks be y.

Cost of each brick = $0.38

Total cost of x bricks = 0.38*x

Cost of each block = $1.56

Total cost of y blocks = 1.56*y

Total amount spent for the brickyard = $24.80

So,

Total cost of x bricks + Total cost of y blocks = Total amount spent for the brickyard

=> 0.38x + 1.56y = 24.80 ____equation (1)

Total number of items (bricks+blocks) = 28

So,

Number of bricks + Number of blocks = Total number of items

=> x + y= 28 ____equation (2)

We will solve the two equations by the method of elimination.

Let's multiply equation 2 by -0.38

(-0.38)*x + (- 0.38)*y  = (-0.38)*(28)

=> -0.38x - 0.38y  = -10.64 ____equation (3)

Adding equation 1 to the equation 3, we get

-0.38x - 0.38y + 0.38x + 1.56y = -10.64 + 24.80

Cancelling out -0.38x and +0.38x on the left side, we get

1.56y - 0.38y = 24.80-10.64

=> 1.18y = 14.16

Dividing both sides by 1.18, we get

[tex]\frac{1.18y}{1.18}[/tex]  =[tex]\frac{14.16}{1.18}[/tex]

=> y = 12

Plugging in y=12 in the equation 2, we get

x + y= 28

=> x + 12 =28

Subtracting 12 from both sides, we get

x+ 12 -12 = 28- 12

Cancelling out the +12 and -12 from the left side, we have

x = 16

So, the number of bricks is 16 and the number of blocks is 12.
