If it's $2.70 now, the cost would be $4.45 in 1995.
To find the 1995 cost of a movie ticket that was $2.70 in 1980, divide the 1995 CPI by the 1980 CPI and multiply by the 1980 price. The calculation yields a cost of approximately $4.99 for a movie ticket in 1995.
Explanation:To calculate the cost of a movie ticket in 1995 using the Consumer Price Index (CPI) from 1980 to 1995, we can use the formula to adjust prices based on inflation:
Determine the ratio of the CPI in 1995 to the CPI in 1980.Apply this ratio to the cost of the item in 1980 to find the equivalent cost in 1995.Let's assume the cost of a movie ticket in 1980 was $2.70. The CPI for 1980 is 82.4, and for 1995 it is 152.4. We calculate the ratio as 152.4 / 82.4 = 1.8495.
Multiplying the 1980 ticket price by this ratio gives us:
$2.70 * 1.8495 = $4.99 approximately.
Therefore, the cost of a movie ticket in 1995, adjusted for inflation, would be about $4.99.

Determine the x- and y-intercepts of the graph of y=−13x+3 . Then plot the intercepts to graph the equation.
To find the x-intercept of the equation y = -13x + 3, set y to zero and solve for x to get (3/13, 0). For the y-intercept, set x to zero and solve for y, resulting in (0, 3). These intercepts are then plotted and connected to graph the equation.
Determining X and Y Intercepts
To determine the x-intercept of the linear equation y = -13x + 3, we need to set y to zero and solve for x:
0 = -13x + 3
13x = 3
x = 3/13
So, the x-intercept is (3/13, 0).
To determine the y-intercept, we set x to zero and solve for y:
y = -13(0) + 3
y = 3
Thus, the y-intercept is (0, 3).
Plotting the Intercepts
On graph paper, mark the x-intercept at (3/13, 0) and the y-intercept at (0, 3). Then use a ruler to draw a straight line that passes through these points; this line represents the equation y = -13x + 3.
The slope is the rate of change along a line. However, in this scenario, the slope is not required to plot the line since we already have the intercepts. Nonetheless, for your reference, the slope (m) in the equation y = mx + b corresponds to -13, indicating a decline of 13 units in the y-direction for each single unit increase in the x-direction.
if amit started work at 6am and left at 1:45 pm how many hours should he record for the day on his time card?
6 hours in the morning (from 6 am to 12 am)
1:45 in the afternoon (from 12 am to 1:45 pm)
sum
6:00 + 1:45 =
7:45 ( 7hours and 45 minutes)
6 am to 12 pm is 6 hours.
12 pm to 1 pm is 1 hour.
So you have 7 hours 45 min.
Since 45 min is 3/4 of an hour you would add it up to get 7.75 hours.
Your answer is 7.75 hours.

You are remodeling your kitchen. You’ve contacted two tiling companies who gladly told you how long it took their workers to tile a floor of a similar size. Jim completed half the floor in 12 hours . Pete completed the other half in 10 hours. If Pete can lay 25 more tiles per hour than Jim, what equation would you use to find the rate that Jim can lay tiles. Let x represent Jim’s rate
As given, let Jim's rate = x
Let Pete's rate =y
Jim completed half the floor in 12 hours so it's [tex]12\times rate[/tex]= 12x
Pete completed the other half of the floor in 10 hours so its [tex]10\times rate[/tex]=10y
As floor area is equal so,
[tex]12x=10y[/tex] .............(1)
Now, given is that Pete can lay 25 more tiles per hour than Jim, this gives=
[tex]y=x+25[/tex] ...... (2)
Putting the value of y from equation (2) in equation (1) , we get
[tex]12x=10(x+25)[/tex]
So, the equation is : [tex]12x=10(x+25)[/tex]
If you want to solve it, it becomes:
[tex]12x=10x+250[/tex]
[tex]2x=250[/tex]
[tex]x=125[/tex]
Hence, Jim can lay 125 tiles and Pete can lay 25 more so 125+25=150 tiles.
Answer:
12x=10(x+25)

Considering that 30% of $7.50 is the same as 0.3/7.5, you would get $2.25 as the markup price. So by adding $7.50 with $2.25, Brittany would charge $9.75 per car magnet.
True or False: For any two integers a and b, (a-b)^2 = a^2-b^2
Expanding the expression, it is found that the statement is false.
---------------------------
The statement given is: [tex](a - b)^2 = a^2 - b^2[/tex]Expanding the left side, we get:[tex](a - b)^2 = (a - b)(a - b) = a^2 - ab - ab + b^2 = a^2 - 2ab + b^2[/tex]
Which is different than the statement, and thus, the statement is false.The expression is also known as a notable product, the perfect square binomial.A similar problem is given by: https://brainly.com/question/17202374
The statement is false. The square of difference of two quantities is not equal to the difference of their squares. The correct expression for [tex](a-b)^2 is a^2 - 2ab + b^2, not a^2 - b^2.[/tex]
Explanation:The statement For any two integers a and b,[tex](a-b)^2 = a^2-b^2[/tex] is false. Let's illustrate why this is incorrect with an example. If we let a = 2 and b = 1, then the left-hand side of the equation [tex](a-b)^2[/tex] would give us [tex](2-1)^2[/tex] = 1 and the right-hand side of the equation [tex]a^2 - b^2[/tex] would give us 2² - 1² = 3 which are not equal.
It's important to note that (a - b)² can be expanded to a² - 2ab + b² in accordance with the square of a binomial formula, which is definitely not equal to [tex]a^2 - b^2[/tex]. A common mistake is to drop the middle term in the expansion (-2ab), which leads to this incorrect equation.

The population of a city can be modeled with a linear equation, y = –80x + 3,450, where x is the number of years after 2000 and y is the city’s population. Write a description of the city’s population based on the equation.
Answer:
Initial population is 3450 in the year 2000 and it decreases 80 every year.
Step-by-step explanation:
We are given with y=-80x+3450 where y is city's population and x is the number of years after 2000.
That is x=0 means the year 2000.
Hence y-intercept will represent the initial population which is nothing but 3450.
Since our equation slope =-80 which is negative means y is decreasing as x increases.
For x raises by 1, y decreases by 80.
That means population decreases by 80 for every year.
Answer:
The y-intercept indicates the population in the year 2000, so 3,450 people lived in the city in 2000. The negative slope indicates that the city is losing population. It loses 80 people each year.

liquid A has a density of 1.4 g/mL , liquid B has a density of 5.9 g/mL and liquid c has a density of 3.2 g/ mL. arrange the three liquids ina density column ( explain your answer)
Liquid B
Liquid C
Liquid A
Because the denser layers sink and the less dense layers float to the top, just like oil and water, the water is more dense than the oil, that is why the oil floats to the top and the water remains at the bottom:))
At the bottom of the density column there is liquid B with a density of 5.9 g/ml, in the middle liquid C with a density of 3.2 g/ml and in the middle liquid A with a density of 1.4 g/ml be at the top.
Explanation:
To arrange liquids A, B, and C in a density column, you must consider their respective densities, since the highest density liquid stays at the bottom and the lowest density liquid floats at the top. Liquid B has the highest density (5.9 g/ml), then liquid C with a density of 3.2 g/ml, then liquid A with the lowest density, 1.4 g/ml. Therefore, when arranging these liquids in a density column, place liquid B at the bottom, liquid C in the middle, and liquid A at the top.

which algebraic rule describes the 270° counter-clockwise rotation about the origin?
a) (x, y) → (−x, y)
b) (x, y) → (x, −y)
c) (x, y) → (y, −x)
d) (x, y) → (−y, x)
270 degree counter clockwise is the same as 90 degrees clockwise.
If you imagine the (x,y) axes rotating 90 clockwise, you will see that what x becomes y, and what was y becomes negative x (after the rotation).
So x-->y, and y-->-x
So the answer (c) is the correct one.
Answer:
option C
Step-by-step explanation:
the correct answer is option C
when a point (x, y ) means point lies in the first quadrant is rotated counter-clockwise to 270° means now the point will be in the fourth quadrant.
hence, in algebraic notation we interchange x by negative x
and y remains the same and their value interchanges so,
the best-suited answer will be (x, y) → (y, -x)
hence, the answer will be option C

We need to solve the equation for x. Where x is the radius of the circle.
In order to solve it for x, we need isolate it for x on left side.
So, first we need to get rid pi from left side.
On dividing both sides by pi, we get
