Final answer:
The price of an item can increase due to inflation, a reduction in supply, or an increased demand. High inflation rates make it challenging to determine the exact causes of price increases and complicate decision-making for both consumers and businesses.
Explanation:
The price of an item can increase due to various factors such as inflation, a decrease in the supply of the good, or an increase in the demand for the good. In situations of high inflation, such as the case in Israel in 1985 with an annual inflation rate of 500%, prices can change so frequently that stores might not post prices directly on items. This makes it challenging for consumers and businesses to respond to economic signals, complicates price comparisons, and makes it difficult to deduce the cause of price increases.
Inflation implies a general increase in prices and can affect all goods and services, leading consumers to spend money quickly before prices rise further. A decrease in supply, perhaps due to production issues or scarcity of resources, can lead to higher prices if demand remains constant. Conversely, an increase in demand for a good without a corresponding increase in supply can also drive prices up. Recognizing the reasons behind rising prices can be complex, especially when high inflation rates obscure the underlying economic indicators.

Answer: 12 texts per dollar.
The slope of the line is 1/5
Step-by-step explanation: If Ruby can send 48 text messages for $4, we divide 48 by 4 to get amount of texts per dollar: 12. Ruby can send 12 text messages for $1.
To figure out the slope of a line, use the formula y2 - y1 / x2 - x1.
-4 - (-9) / 22 - (-3) = 5 / 25 (rise over run)
Simplify to 1/5
Consider the functions shown below.
Determine which of the following statements is true.
A.
As the value of x decreases, both the values of f(x) and g(x) will eventually be negative.
B.
At x = -1, f(x) = g(x).
C.
For x ≤ 1, g(x) < f(x).
D.
As the value of x increases, the value of g(x) will eventually exceed the value of f(x).
Answer: D
Step-by-step explanation:
A. False
f(x): x → -∞, y → -∞
g(x): x → -∞, y → 1
B. False
at x = -1, f(x) = -7
at x = -1, g(x) = 1.5
C. False
refer to A
g(x) → 1 and f(x) → -∞ so g(x) > f(x)
D. TRUE
It is hard to tell from the graph so plug in a value to check.
f(10) = 5(10) - 2
= 50 - 2
= 48
g(10) = 2¹⁰ + 1
= 1024 + 1
= 1025
g(10) > f(10)
gretchen made 189 cookies in 4.5 hours what was her rate in cookies per hour
Answer: 42 cookies/1 hour
Step-by-step explanation: Since Gretchen made 189 cookies in 4.5 hours, we set the equation up as 189/4.5. To get cookies per hour, we divide 189 by 4.5, which is 42/1. This means that Gretchen can make 42 cookies in 1 hour.
Tom and Jack “power walk” towards each other at the same time. Tom’s walking speed is 2.3 m/s, Jack’s speed is 2.2 m/s. They meet each other 1.5 minutes after they started. How far apart were they to begin with?
Answer:405 meters apart. I think the m means meters, if it meant miles that would be incredible :)
Step-by-step explanation: 2.3 times 1.5 minutes is 90 seconds, so 2.3 times 90=207. 2.2 times 90 =198. 207+198=405

the amusement park also has water rides 30% of the 80 rides are water-related how many water-related rides does the park have
Answer:
24.
Step-by-step explanation:
So you need to fine 30% of 80.
I did the following method:
-Break it down, and do, 80 -/- 10 which is 8, now you have 10%, and you need to find 30, times your 10% by 3, so 24.
-Therefore, 24 out of 80 rides at the amusement park are water-related.
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.
Explanation: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.

chapman’s brickyard sells brick and blocks. a brick costs .38 dollars and a block cost 1.56 dollars. the brickyard filled with a 24.80 dollars order, which contained 28 items
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.

Which is a disadvantage of using cash as a payment method? Accepted almost everywhere. Has no fees or interest. Must hand deliver all payments. Fraud is rare except occasional counterfeiting.
Answer:
i would say the last choice
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.
Explanation: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.

The volume of a rectangular prism is 2x^3+9x^2-8x-36 with height x + 2. Using synthetic division, what is the area of the base?
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]

Determine the degree of the polynomial:
–3.1ax^4+2.5ax+2ax^4+1.1ax^4–0.5ax–2ax
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.
