Answer: 113.5

Step by Step Explanation:

The tile should Orchid choose, to minimize costs, is rectangular tiles. The total cost will be $8 less.

Area of square is the square of its sides length. Area of rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length rectangle and (b) is the width of the rectangle.

Orchid wants to retile her bathroom floor, which has an area of 40 square feet.  She is deciding between two types of custom tiles.

The square tile is One-half foot by One-half foot. Thus, the area of square tile is,

[tex]A=\left(\dfrac{1}{2}\right)^2\\A=\dfrac{1}{4}\rm ft^2[/tex]

Total square tiles required for 40 square feet area,

[tex]n=\dfrac{40}{\dfrac{1}{4}}\times\\n=160[/tex]

Square tile costs $0.45 per tile. Thus, the cost of 160 square tile is,

[tex]C_s=0.45\times160\\C_s=72[/tex]

The rectangular tile is 2 feet by One-fourth foot. Thus the area of thios tile is,

[tex]A_r=2\times\dfrac{1}{4}\\A_r=\dfrac{1}{2}\rm\;ft^2[/tex]

Number of rectangular tiles required for 40 square feet area,

[tex]n=\dfrac{40}{\dfrac{1}{2}}\\n=80[/tex]

The cost of this tile is $0.80 per tile. Thus, the cost of 80 rectangle tiles is,

[tex]C_s=0.8\times80\\C_s=64[/tex]

Hence, the cost of rectangular tile is $8 less than the square tile.

Thus, the tile should Orchid choose to minimize costs, is rectangular tiles. The total cost will be $8 less.

Answer:

A

Step-by-step explanation:

every term of the sequence is created by multiplying the previous term by -2.4

to get the ratio (or multiplication factor) of the sequence :

4 × r = -9.6

r = -9.6/4 = -2.4

and as you can easily check, the following y values use the same factor.

so, as multiplication is used, it is a geometric sequence.

if addition were used, it would be an arithmetic sequence.

but the differences between the y values are clearly not constant (as it would be, if we added a fixed constant to every term to create the next).

so, B and D are automatically wrong.

and C is wrong, because the given ratio or multiplication factor cannot be right :

4 × 0.4 = 1.6 and never -9.6

Answer:

a_n = 244 + 57n, for n ≥ 1

Step-by-step explanation:

358 - 301 = 57

415 - 358 = 57

472 - 415 = 57

There is a constant difference, so the sequence is arithmetic.

a_1 = 301

a_2 = 358 = a_1 + 57

a_3 = 415 = a_1 + 57 × 2

a_4 = 472 = a_1 + 57 × 3

a_n = a_1 + 57 × (n - 1)

a_n = 301 + 57(n - 1)

a+n = 301 + 57n - 57

a_n = 244 + 57n, for n ≥ 1

Answer: When the sum of two angles is 90°, then the angles are known as complementary angles. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles. Here we say that the two angles complement each other.

Step-by-step explanation:

Answer:

150, 108, 90 , 12

Step-by-step explanation:

Angle in France:

= Fraction occupied by France x 360 degrees

= 25/60 x 360

= 150

Angle in Spain:

= 18/60 x 360

= 108

Angle in Greece:

= 15/60 x 360

= 90

Angle in OTHER:

= 2/60 x 360

= 12

Answer:

$352.80

Step-by-step explanation:

First, we need to find the area of the room.

A = L * W

A = 14 * 12

A = 168 ft²

Now, we need to find the cost.

168 ft² * $2.10 per ft² = $352.80

     It will cost $352.80 to carpet the room

Answer:

1/2400  or 0.0004167

Step-by-step explanation:

The question can be written as :

5/6 ÷ 2000/1

This is equal to:

5/6 * 1/2000 -------introducing the product sign and the reciprocal of 2000/1

simplify as;

5/6 * 1/2000 = 1/6 *1/400 ---------dividing 5 by 2000 to get 1/400

perform multiplication

1/6 * 1/400 = 1/2400

Nolan did not make an error while estimating the square root of number 18 and his all the steps are correct.

A real square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.

Nolan used the following procedure to find an estimate for

[tex]\sqrt{18}[/tex]

The square of the number 4 is,

[tex]4^2=16[/tex]

The square of the number 5 is,

[tex]5^2=25[/tex]

Number 18 lies between these number as,

[tex]16 < 18 < 25[/tex]

Therefore, the [tex]\sqrt{18}[/tex] is somewhere between the number 4 and 5.

Since 18 is closer to 16, square the tenths closer to 4.

[tex]{4. 1 }^2= 16. 81\\{4. 2 }^2= 17.64\\{4. 3}^2= 18.49\\{4. 4}^2= 19.36\\[/tex]

This step is also correct, when squaring.

Since 18.49 rounds to 18, 4.3 is the best approximation for [tex]\sqrt{18}[/tex].

All the above steps are correct.

Thus, Nolan did not make an error while estimating the square root of number 18 and his all the steps are correct.

Answer:

Step-by-step explanation:

The vertex coordinates of  f(x) = ax² + bx + c  are:  (h, k)

where:   [tex]h=\dfrac{-b}{2a}\ ,\qquad k=f(h)[/tex]

f(x) =  x² - 6x + 11       ⇒  a = 1   b = -6

So:

     [tex]h=\dfrac{-(-6)}{2(1)}=\dfrac6{2}=3\\\\y=f(h)=-(3)^2-6(3)+1=-9-18+11=-16[/tex]

The vertex of quadratic equation is (3, 2)

In order to determine the coordinates of the vertex, if they are not clearly labeled or easily identified from the graph, we will need to know the equation for the parabola. In general, the equation of a parabola has the form

y=ax²+bx+c

where a, b, and c are all real numbers, and a≠0.

This is called a quadratic equation, and this form is called the standard form of a quadratic equation.

The vertex of the parabola is located at a pair of coordinates which we will call (h, k). In order to determine what they are, we can simply use the standard form of the quadratic equation.

h=−b/2a.

Given:

y= x² - 6x + 11

Now,

h= -b/2a

h= -(-6)/ 2 * 1

h= 3

Now,

y= f(h)

 = 3*3 - 6*3 +11

 = 9 -18 +11

 = -9 +11

 = 2

Answer: 465m squared

(But I think I did this wrong)

Step-by-step explanation:

First, find the area of the whole thing

So 23 x 23 = 529

Now the field: 16 x 16 = 64

Then, subtract both of the areas to find the area of the path:

529 - 64 = 465

Answer:

5x + 4y = 80

Step-by-step explanation:
First, let us look at the given:

x = The number of songs purchased

y = The remaining balance of Renata's gift card

Coordinates:

1. (16,0)

2. (0,20)

Now let's look at the unknown:

Slope =?

Since we have the coordinates we can easily apply the slope formula

Now that we have our slope we can use either point-slope formation or slope-intercept formation, just pick whichever one you're comfortable with.

Point-slope formation

y - y1 = slope (x - x1)

Now just plug in the numbers:

y - 0 = 20/-16 (x - 16)

Now you multiply both sides by -16 to get rid of the fraction

-16(y - 0) = -16 (20/-16) (x - 16)

-16y - 0 = 20 (x - 16)

-16y = 20x - 320

Now subtract 20 from both sides.

-16y - 20x = 20x - 20x - 320

-20x - 16y = -320

Now we need to simplify both sides so we divide both sides by 4

-5x - 4y = -80

Now, remember, one of the rules of standard formation is that the coefficient of x cannot be smaller than zero. So you need to multiply both sides by -1.

-1 (-5x - 4y) = (-80) -1

5x + 4y = 80
