Answer: No, as the total cost of the 3 shirts w/ sales tax is $45.36 and she only has $45.
Step-by-step explanation:
Start by finding the price of one shirt on sale.
[tex]18*0.2[/tex]
This equals 3.6 which is how much will be deducted from the original price.
One shirt costs [tex]18-3.6\\[/tex] when its 20% off.
This is equal to $14.40.
Since she wants to buy 3 of them we just multiply the $14.40 by 3.
[tex]14.4*3=\\[/tex]
This equals $43.2 but this is without a 5% sales tax which is normally added to the total end price.
To add a sales tax you take the sales tax percent plus 1 and multiply it to the $43.2.
[tex]43.2*1.05=\\[/tex]
This means the total price of Kayla's purchase will be $45.36.
This is over her $45 she has so she can not buy it.
Answer: she does not and is over $45.36 (.36) cents over

Find the slope of the line. please. help.
Answer: the slope is up 1 and to the right 2, or if your going the opposite direction it would be down 1 and to the left 2
Answer:
1/2
Step-by-step explanation:
Slope is change in y over change in x. The change in Y is 2.5 - 1= 1.5 .The change in X is 1 - (-2)= 3 . Therefore, the slope is 1.5/3 which simplifies to 1/2

Factor the quadratic expression completely: 15x^2 - 4x -4
WHY IS THIS SO HARD !!!!!
Step-by-step explanation:
We can rewrite as 15x² + 6x - 10x - 4. The first two and last two terms have common factors so this turns into 3x (5x + 2) - 2 (5x + 2). This will then become (5x + 2)(3x - 2).
Answer:
(-2 + -5x)(2 + -3x)
Simplifying
15x2 + -4x + -4
Reorder the terms:
-4 + -4x + 15x2
Factor a trinomial.
(-2 + -5x)(2 + -3x)
Final result:
(-2 + -5x)(2 + -3x)

A bakery is 10 yards wide and 17 yards long. The baker wants to put a wooden shelf around the inside of the bakery. The wooden shelving costs $10.82 per yard. How much will the baker's shelf cost?
Answer:
$584.28
Step-by-step explanation:
first, add up the yards around the perimeter of the bakery. 10 + 10 + 17 + 17 = 54. Then, multiply 54 by 10.82 to get the cost of the shelf.
54 x 10.82 = 584.28

What is the surface area of the figure?
A. 12cm
B. 24cm
C. 28cm
D. 42 cm
Answer:
B: 24 cm
Step-by-step explanation:
The triangle is ((4*3)/2). The squares are 12 (3*4) and 6 (1.5*4)
Answer:
24 cm^2
Step-by-step explanation:
We can find the area of the figure, surface area is for three dimensional figures
The area of the triangle is
A = 1/2 bh
A = 1/2 (3) *4 = 6
The area of the top rectangle is
A = l*w = 3 * (8-4) = 3* 4 = 12
And the area of the bottom rectangle
A = l*w = 1.5 ( 8-4) = 1.5*4 =6
The total area is the sum of the individual areas
6+12+6 = 24
24 cm^2

14. Compare the graph below to the function
Answer:
Option (2)
Step-by-step explanation:
Parent function has been given as,
f(x) = [tex]\sqrt{x}[/tex]
When translated by 3 units left,
f(x + 3) = [tex]\sqrt{(x+3)}[/tex]
g(x) = [tex]\sqrt{(x+3)}[/tex]
If the translated function is stretched vertically by a scale factor = k
New function will be,
g'(x) = [tex]k\sqrt{(x+3)}[/tex]
Since a point (1, 4) passes lies on the transformed function.
g'(1) = [tex]k\sqrt{(1+3)}[/tex]
4 = 2k
k = 2
Therefore, transformed function represents the translation by 3 units in the negative side of the x-axis and stretched vertically by 2 units.
Option (2) will be the answer.

This tennis ball has an diameter of 2.7 inches. What is the volume of this tennis ball? Use 3.14 for π and round your answer to a whole number.
Answer:
V = 10 in^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
We have the diameter
r = d/2 = 2.7/2 =1.35
V = 4/3 ( 3.14) (1.35)^3
V =10.30077
Rounding to the nearest whole number
V = 10 in^3

A serving tray is in the shape of a rectangular prism without a top. The dimensions of the tray are 8 inches by 10 inches by 2 inches. What is the surface area of the tray?
A: 152 square inches
B: 212 square inches
C: 216 square inches
D: 232 square inches
Answer:
it's a 152
Step-by-step explanation:
The surface area of the rectangular prism is S = 232 inches²
What is the surface area of the prism?The surface area of the prism is calculated as
The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism
Surface Area of the prism = 2B + ph
The area of the triangular prism is A = ph + ( 1/2 ) bh
Given data ,
A serving tray is in the shape of a rectangular prism without a top.
And , dimensions of the tray are 8 inches by 10 inches by 2 inches.
So , surface area A = 2(80) + 2(16) + 2(20)
A = 160 + 32 + 40
A = 232 square inches
Hence , the surface area is 232 inches²
