Hi yess my user name is my number teehee

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.

Hans would take 13.5 seconds to run 50 meters

Priya would take 12 seconds to run 50 meters

--------------------------------------------------------------------------------

Since they each ran 10 meters for a certain amount of time you would multiply the seconds by 5 since 10x5=50

When you do that you get

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:

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

Step by Step Explanation:

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.

A = 14 * 12

A = 168 ft²

Now, we need to find the cost.

168 ft² * $2.10 per ft² = $352.80

Answer:

Crystal's mistake was that she distributed the 5 only to the 4, not to the 7 as well.

The correct step should have been 5(4 + 7) = 5⋅4 + 5⋅7.  

Using the distributive property correctly would give the sum of the two products, 20 + 35. The value of 5(4 + 7) is 55.

The value of 5(4 + 7) is 55.

It is required to find the correct answer.

Simplification means simplifying processes involved in work towards consistency of efforts, costs and time. It eliminates useless and disadvantageous (or unnecessary) diversity and variety.

Given that:

By the Distributive Property

If a, b, c are real numbers, then

a*(b+c)=a*b+a*c

Crystal's did mistake was that she distributed the 5 only to the 4, not to the 5 to 7 as well.

First distribute and then multiply, we get

The correct step should have been

= 5(4 + 7)

= 5⋅4 + 5⋅7.  

= 20 + 35.

= 55

Therefore, the value of 5(4 + 7) is 55.

This is equal to:

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

perform multiplication

1/6 * 1/400 = 1/2400

Answer : 1/2400  or 0.0004167

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
