Answer:
b. She should choose the rectangular tiles because the total cost will be $8 less.
Step-by-step explanation:
Which tile should Orchid choose to minimize costs? Explain.
a. She should choose the square tiles because the total cost will be $8 less.
b. She should choose the rectangular tiles because the total cost will be $8 less.
c. She should choose the square tiles because the total cost will be $14 less.
d. She should choose the rectangular tiles because the total cost will be $14 less.
Area of a square tile = 1/2 × 1/2
= 1/4
= 0.25 square feet
Area of rectangular tile = 2 × 1/4
= 2/4
= 0.5 square feet
Number of square tile needed = Area of the bathroom floor / Area of the square tile
= 40 square feet / 0.25 square feet
= 160
Number of square tile needed = 160
Cost of square tile needed = number of tiles × cost per tile
= 160 × $0.45
= $72
Cost of square tile needed = $72
Number of rectangular tile needed = Area of the bathroom floor / Area of the rectangular tile
= 40 square feet / 0.5 square feet
= 80
Number of rectangular tile needed = 80
Cost of rectangular tile needed = number of tiles × cost per tile
= 80 × $0.80
= $64
Cost of rectangular tile needed = $64
Cost of square tile needed = $72
Cost of rectangular tile needed = $64

Use the multiplier method to increase £258 by 43%
You must show your working out.
Answer:
£368.94
Step-by-step explanation:
The multiplier for 43% is 0.43
0.43 x 258 = 110.94 which is 43%
But if you are increasing 258 by 43% you must add on 258 as well
Or instead you can just do 258 x 1.43= 368.94

pls help me ASAP!! what is the surface area of this design? a) 288in b) 256in c) 96in d) 160in
Answer:
b) 256 inches
Step-by-step explanation:
8x5x2 = 80 (top & bottom)
8x5x2 = 80 (front & back)
8x8x2 = 128 (gross area of 2 sides)
4x4x2 =32 (delete this for side cutouts) Guessing the cutoff dimension on
left side is 4m inch.
80+80+128-32 = 256 inches

The areas of sectors ACB and DEF are equal. what expression gives the values of x?show your work
Answer:
I think this is right thanks :)
find the exact value of the composite function show work
Answer:
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
Step-by-step explanation:
This function can be written as:
[tex]\frac{1}{cos(sin^{-1}(\frac{1}{2x})) }[/tex]
[tex]sin^{-1}(\frac{1}{2x})[/tex] means the angle whose sine is 1/(2x). This implies that the denominator is the cosine of the angle whose sine is 1/(2x)
Think of a right triangle and consider the angle with this sine. Then the opposite side has length 1 and the hypotenuse has length 2x. The Pythagorean theorem then implies that the adjacent side is
[tex]\sqrt{4x^{2} -1}[/tex]
The cosine of the angle is adjacent over hypotenuse, so the cosine is
[tex]\frac{\sqrt{4x^{2} -1}}{2x}[/tex]
The secant is the inverse of the cosine, so the answer is
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
One of the two numbers ends in zero. If you cross out the zero, you get the second number. Find these numbers if their sum is 363.
Answer:
330 + 33 = 363
Step-by-step explanation:
The answers you are looking are 330 and 33.
If you were to take 330 and 33 and add them together, it would equal 363. The question also states if you were to take the 0 off of the first number (330), youd get your second number (33) to equal the sum given.
I hope this helps!
Tell whether (4, 27) is a solution of y=3x+15
Answer:
Yes
Step-by-step explanation:
We have two properties for our question :
(4, 27)
y = 3x + 15
We are being asked whether the point (4, 27) is a solution of y = 3x + 15
So how do we figure this out? Well, what we have to know first that (4, 27) represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.
y = 3x + 15
y = 27 and x = 4
27 = 3(4) + 15
27 = 12 + 15
27 = 27
Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15

Multiply the two polynomials and write your answer in standard form – 3x (4x - 2)
Answer:
-12x^2+6x
Step-by-step explanation:
-3x(4x-2)
-12x^2+6x
The standard form of the polynomial is -12x² +6x.
What is a polynomial?A polynomial is an equation made up of exponents, constants, and variables that is combined using mathematical operations including addition, subtraction, multiplication, and division.
The given expression is – 3x (4x - 2)
Solving further,
–3x (4x - 2)
=-12x² +6x.
The standard form of the polynomial is -12x² +6x after multiplying – 3x (4x - 2)

.......I am not sure...
- Mia and Lily are trying to find the nearest whole number to the square root of 120
Mia: It is 10
Lily: It is 11
Who is correct?
Give a reason for your answer.
For determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.
Given that,
Mia has 10 number.And, Lily is 11 number.Now if we square both the numbers so it comes:
10^2 = 10011^2 = 121So, 121 is nearest to 120.
Therefore we can conclude that for determining the nearest whole number for the square root of 120, the Lily is correct i.e. it is a square of 11.
