Answer:
$551.70
Step-by-step explanation:
Price before tax= $511.99
Cost of the tax= 7.75/100×511.99
= $39.679
Total cost of the camera= $511.99+$39.679
= $551.669
≈ $551.70

Mr chow is buying rolls of paper for the school. This is a lost of the suppliers, the size of their rolls, and their cost per roll. supplier x sells 25 meter rolls for 18.98, supplier y sells 30 meter rolls for 21.89, supplier z sells 40 meter rolls for 29.59 to the nearest cent what is the cost per meter for a roll of paper from the least expensive supplier
Answer:
0.73
Step-by-step explanation:
cost per meter for a roll of paper = total cost / total meter of rolls sold
Supplier x = 18.98 / 25 = 0.76
Supplier y = 21.89 / 30 = 0.73
supplier z = 29.59 / 40 = 0.74
the lowest per unit cost is 0.73

A square room has a perimeter of 40 feet. What is the area of the room?
Answer:
100 ft²
Step-by-step explanation:
There are 4 congruent sides in a square
Perimeter = 4x
40 = 4x
x = 10
Area = base x height or length x width
Since all sides are the same, 10 is base and height
10x10 = 100
units = ft²
Answer = 100 ft²

-Chetan K
Answer:
100 feet (I forget area units so there might be an exponent or something)
Step-by-step explanation:
Basically, the formula for perimeter is the sum of all sides. With area, you are just multiplying length times width. With a square, all of the sides are equal, and there are four sides. 40/4=10. So, each side is 10 feet. With that, you can multiply 10*10 and get 100!

Drag each tile to the correct box. Amanda, Derrick, and Todd attend the same high school. Each student works as the cashier one night a week at the school's concession stand. The number of items sold at the concession stand to the first 20 customers on three different nights is represented on the dot plots below. Find the interquartile range, IQR, for each dot plot. Then, place the students in order from greatest to least IQR.
Answer:
Amanda > Todd > Derrick
Step-by-step explanation:
Amanda's IQR- 3.5
Derrick's IQR- 2
Todd's IQR- 3
The solution is, ordering the IQR in descending order :
Emma, Sally, Olivia
What is IQR?The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set. Whereas the range gives you the spread of the whole data set, the interquartile range gives you the range of the middle half of a data set.
here, we have,
Writing out the points obtained from the dot plot, and applying the relevant formula, the Interquartile range of each dot plot is given below ;
Writing out each score on the dot plot to calculate the statistical values :
Emma's Scores:
6 , 7 , 8 , 8 , 9 , 9 , 9 , 10 , 10 , 11 , 11 , 11 , 11 , 11 , 12 , 13 , 13 , 13 , 13 , 14
Q1 = 1/4(n+1)th term
Q1 = (5th + 6th) terms
Q1 = (9 + 9) / 2 = 9
Q3 = 3/4(n+)th term
Q3 = (12 + 13) ÷ 2 = 12.5
IQR = Q3 - Q1
IQR = 12.5 - 9 = 3.5
Sally's Scores:
6 , 6 , 6 , 7 , 7 , 8 , 8 , 8 , 9 , 9 , 10 , 10 , 10 , 10 , 10 , 10 , 11 , 11 , 12 , 12 , 14
Q1 = 1/4(n+1)th term
Q1 = (7 + 8) ÷ 2 = 7.5
Q3 = 3/4(n+1)th term
Q3 = (10 + 11) ÷ 2 = 10.5
IQR = Q3 - Q1
IQR = 10.5 - 7.5 = 3
Olivia's Scores:
6 , 6 , 7 , 7 , 7 , 8 , 8 , 8 , 8 , 9 , 9 , 9 , 9 , 9 , 10 , 10 , 12 , 12 , 13 , 14
Q1 = 1/4(n+1)th term
Q1 = (7 + 8) ÷ 2 = 7.5
Q3 = 1/4(n+1)th term
Q3 = (10 + 10) ÷ 2 = 10
IQR = Q3 - Q1
IQR = 10 - 7.5 = 2.5
Therefore, ordering the IQR in descending order :

Determine the volume of a cylinder with 251.20cm2 lateral area and 78.50cm2 base area
Answer:
Answer is 628 cm^3
Step-by-step explanation:
using base area lets find radius
base area=pie*(r)^2
78.50=3.14*r^2
78.50/3.14=r^2
25=r^2
5=r
now using lateral area lets find height
lateral area=2*pie*r*h
251.20=2*3.14*5*h
251.20=31.4*h
251.20/31.4=h
8=h
volume of cylinder=pie*(r)^2*h
=3.14*(5)^2*8
3.14*25*8
=628 cm^3

Below is the entire graph of function f graph f^-1, the inverse of f
The graph of the inverse of a function is its reflection across the line y = x
Please find attached the required graph created with MS Excel
The graph of the inverse of a function is reflected over the line y = x
In order to graph the function f⁻¹, either the line y = x is drawn and the points of f⁻¹ are traced by taking equal distance from the line y = x, or the x, and y-coordinates of the f are reversed to get the coordinates of f⁻¹ as follows;
The reflection of the point (x, y) across the line y = x is (y, x)
The vertices of the graph of the function f, staring from the top are;
(5, 6), (3, -3), (-3, -5)
Therefore, we have;
The reflection of the point (5, 6) across the line y = x is (6, 5)
The reflection of the point (3, -3) across the line y = x is (-3, 3)
The reflection of the point (-3, -5) across the line y = x is (-5, -3)
The graph of the function f⁻¹ can be plotted using MS Excel, and the above values, as shown in the attached diagram

Solve 3x2 + x - 10 = 0. Round solutions to the nearest hundredth. (5 points) a x ≈ −5 and x ≈ 2 b No real solutions c x ≈ −2 and x ≈ 1.67 d x ≈ −1.67 and x ≈ 2
Answer:
c) x ≈ −2 and x ≈ 1.67
Step-by-step explanation:
Solve 3x²+ x - 10 = 0.
We solve using Almighty formula
-b ± √b² - 4ac/2a for equation: ax² + bx + c
where a = 3, b = 1, c = -10
Hence
-1 ± √1² - 4 × 3 × -10/2 × 3
-1 ± √1 - (-120)/6
-1 ± √1 + 121/6
-1 ± √121/6
-1 ± 11/6
Hence:
-1 - 11/6
-12/6 = -2
-1 + 11/6
= 10/6
= 1.67
Therefore, x = -2, x = 1.67
Option c) x ≈ −2 and x ≈ 1.67 is the correct answer

Step-by-step explanation:
here is the complete question
Amy is baking muffins. Each baking tray can hold 6 muffins.
a. If Amy bakes 4 trays of muffins, how many muffins will she have in all?
b. The corner bakery produced 10 times as many muffins as Amy baked. How many muffins did the bakery produce?
If the Corner Bakery packages the muffins in the boxes of a 100 how many boxes of a 100 could they make
Number of muffins Amy has = number of trays x capacity of each tray
6 x 4 = 24 muffins
b. Muffins the bakery produces = 10 x 24 = 240 muffins
c. Number of boxes = 240 / 100 = 2. 4

Dawson's Garage charges $55 per hour to do car repairs plus the cost of the parts.
Part A
Write an equation to model this situation using h to represent the number of hours the repairs take, p to represent the cost of the parts and, cto represent the
total cost of the repairs.
Part B
What will the cost of the repairs be if the parts cost $142 and it takes 4 hours to do the repairs?
$
Answer:
Part A
c = p + 55h
Part B
$362
Step-by-step explanation:
Dawson's Garage charges $55 per hour to do car repairs plus the cost of the parts.
Part A
h = the number of hours
p = the cost of the parts
c = the total cost of the repairs.
The equation to model this situation is written as:
c = p + $55 × h
c = p + 55h
Part B
What will the cost of the repairs be if the parts cost $142 and it takes 4 hours to do the repairs?
From the above question:
p = $142
h = 4
Since our equation =
c = p + 55h
Hence,
c = 142 + 55 × 4
c = 142 + 220
c = 362
Therefore, the cost of repairs = $362
