Answer:
$10
Step-by-step explanation:
To calculate markup, you take you cost and then multiply it by the markup percentage (in decimal form), then add that number to the original cost. So the formula will look like this.
Selling Price = Cost + (Cost X Markup Percentage)
Let's use X to be the selling price you are looking for.
X = $7 + ( $7 x 0.43) 0.43 is the decimal value of 43 percent
Work on the numbers in parentheses first:
$7 x 0.43 = $ 3.01
now add that to the original cost:
$7 + $ 3.01 = $ 10.01
Round to the nearest dollar and you have $10.
The manager made the mistake of multiplying the markup percentage and the original cost.
$7 x 0.43 = $ 3.01
He subtracted the markup instead of adding it to the original cost.

The first set:
" {(0, 1), (1, 2), (2, 3), (3, 3)}"
Represents a function.
Which set of ordered pairs represents a function?
A function is a relationship that maps elements from a set (inputs) into elements from another set (output). Such that each input can be mapped into only one output.
Then, for example, the second set:
{(0, 1), (1, 2), (1, 3), (2, 5)}
Is not a function, because the input x = 1 is being mapped into y = 2 and y = 3.
The only case where the inputs are not repeated is on the first set:
" {(0, 1), (1, 2), (2, 3), (3, 3)}"
Where no input is repeated, so this is a function.

A symphony orchestra is arranged in a semicircle around the conductor. The rows are about 3 feet apart, with the first row about 6 feet from the conductor. A mid-sized orchestra has about 6 rows of chairs. What is the approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note?
Answer:
19 ms
Step-by-step explanation:
We need to find the time it takes for the sound from the 6th row gets to the conductor.
Since there are 6 rows and each row is 3 feet apart, since the orchestra is arranged in a semi-circular manner around the conductor, the distance from the 6 th row to the 1st row is (6 - 1) × 3 = 5 × 3 = 15 feet.
Now, since the conductor is 6 feet from the first row, his distance from the 6th row is 15 feet + 6 feet = 21 feet.
So, time approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note, t = distance between 6th row and conductor/speed of sound.
Speed of sound = 343 m/s
distance between 6th row and conductor = 21 feet. In meters, it is 21 × 0.3048 m = 6.4008 m
t = 6.4008 m ÷ 343 m/s
= 0.019 s
= 19 ms

At the beginning of the season, Jamie pays full price for a ticket to see the panthers, her favorite basketball team. The panthers currently have 33 wins and 31 losses. Represent the total change in the cost of a ticket given their losses. What is the cost of a ticket for the next game they play
Answer:
The answer is below
Step-by-step explanation:
Given that the price of the ticket at the beginning of the season is $49.64 and the ticket price decrease by $0.41 for every loss
a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:
Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71
b) The cost of a ticket for the next game given they have 31 losses is:
Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93
Researchers observed the grouping behavior of deer in different regions.The following scatter plot shows data collected on the size of the group and the percent of the region that was woodland.
The relationship between group size and percent woodland appears to be negative and nonlinear.Which of the following statements explains such a relationship
Answer:
As the percent of woodland increases, the number of deer observed in a group decreases quickly at first and then more slowly.
Step-by-step explanation:
Since the graph is nonlinear, you can rule out answers that say or suggest 'constant change.'

Which of the following answers is the best description for the deer population with the greatest growth rate: A.The blue line shows a deer population that grew with an exponential growth rate. In the first year the population increased by only one deer, but between years seven and eight the population grew by two deer, showing that the growth rate continuously doubles. B.The blue line shows a deer population that grew with a linear growth rate, because the graph shows that the population increased by approximately one deer per year. C. The red line shows a linear growth rate, because an approximate straight line estimates a growth rate of five deer per year. D. The red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing
Answer: D) the red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing.

x - у - 2z = -6
3х + 2y = -25
—4х + у — z = 12
Answer:
(1) x-y-2z=-6 , (2) 3x+2y=-25 , (3) -4x+y-z=12
Step-by-step explanation:
Multiply (3) by 2,
-8x + 2y - 2z = 24
subtract above equation from (1)
9x - 3y = -30 --> 3x - y = - 10
subtract above equation from (2)
3y = -15 --> y = -5
Put y value back into (2)
3x + 2(-5) = -25 --> 3x - 10 = -25 --> 3x = -15 --> x = -5
Put x and y values into (3)
-4(-5) + (-5) - z = 12 --> 20 - 5 - z = 12 --> 15 - z = 12 --> z = 3
Hope its right good luck!!
