The division is one of the four fundamental arithmetic operations. The number of tiles that will be needed to cover the entire area of the hall is 864.

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

The area of the hall with dimensions 6 feet by 8 feet are:

[tex]\rm \text{Area of the hall} = 6 feet \times 8foot =48\ feet^2[/tex]

The area of the tile is 8 square inches, therefore, the area of tile in square feet can be written as,

[tex]\rm \text{Area of the tile} = \dfrac8{12 \times 12}\ feet^2[/tex]

Noe, the number of tiles needed to tile the complete area of the hall is,

[tex]\text{Number of tiles needed} = \dfrac{\text{Area of the hall}}{\text{Area of the tile}}\\\\\\\text{Number of tiles needed} = \dfrac{48}{\frac8{12 \times 12}} = \dfrac{48 \times 12 \times 12}{8} = 864[/tex]

Hence, the number of tiles that will be needed to cover the entire area of the hall is 864.

i strongly believe that is the answer, pls mark as brainlist

Answer:

C

Step-by-step explanation:

The line is dotted, so the sign is non-inclusive.

The dotted line is y = -(4/5)x - 3.

The section of the graph above the line is shaded so this inequality is "greater than".

So, putting these together, you get:

C. y > -(4/5)x - 3

Let a be the first term in the sequence, and d the common difference between consecutive terms. If aₙ denotes the n-th term in the sequence, then

a₁ = a

a₂ = a₁ + d = a + d

a₃ = a₂ + d = a + 2d

a₄ = a₃ + d = a + 3d

and so on, up to the n-th term

aₙ = a + (n - 1) d

The sum of the first 10 terms is 100, and so

[tex]\displaystyle \sum_{n=1}^{10} a_n = 100 \\ \sum_{n=1}^{10} (a + (n-1)d) = 100 \\ (a-d) \sum_{n=1}^{10} 1 + d \sum_{n=1}^{10} n = 100 \\ 10a+45d = 100[/tex]

where we use the well-known sum formulas,

[tex]\displaystyle \sum_{n=1}^N 1 = 1 + 1 + 1 + \cdots + 1 = N[/tex]

[tex]\displaystyle \sum_{n=1}^N n = 1 + 2 + 3 + \cdots + N = \frac{N(N+1)}2[/tex]

The sum of the next 10 terms is 300, so

[tex]\displaystyle \sum_{n=11}^{20} a_n = 300 \\ (a-d) \sum_{n=11}^{20} 1 + d \sum_{n=11}^{20} n = 300 \\ (a-d) \left(\sum_{n=1}^{20} 1 - \sum_{n=1}^{10} 1\right) 1 + d \left(\sum_{n=1}^{20} n - \sum_{n=1}^{10} n\right) = 300 \\ 10a+145d = 300[/tex]

Solve for a and d. Eliminating a gives

(10a + 145d) - (10a + 45d) = 300 - 100

100d = 200

d = 2

and solving for a gives

10a + 145×2 = 300

10a = 10

a = 1

So, the given sequence is simply the sequence of positive odd integers,

{1, 3, 5, 7, 9, …}

given recursively by the relation

[tex]\begin{cases}a_1 = 1 \\ a_n = a_{n-1} + 2 & \text{for }n>1\end{cases}[/tex]

and explicitly by

[tex]a_n = 1 + 2(n-1) = 2n - 1[/tex]

for n ≥ 1.

Step-by-step explanation:

pizza = circle

the area of a circle is

pi×r²

r = radius (half of the diameter). in our case 20/2 = 10".

the circumference of a circle is

2×pi×r

again, r = radius.

in our case that gives us

a.

2×pi×r = 2×pi×10 = 20×pi = 62.83185307... "

b.

the area of the pizza is

pi×10² = 100×pi = 314.1592654... in²

c.

it is 1/8 of the whole area, of course.

314.1592654... / 8 = 39.26990817... in²

d.

it is 1/8 if the whole circumference, of course.

Step-by-step explanation:

apply area of triangle and rectangle and add them

Step-by-step explanation:

For example: Subtract 4x - 10y + 15z from 5x + 8y - 20z.

Step 1: Arrange the polynomials in standard form. In this example, it is already arranged.

Step 2: Place them horizontally.

(4x - 10y + 15z) - (5x + 8y - 20z)

Step 3: Change the sign of the second polynomial through the parentheses.

4x - 10y + 15z - 5x - 8y + 20z

Step 4: Arrange the like terms together.

4x - 5x - 10y - 8y + 15z + 20z

Step 5: Solve the equation

-x - 18y + 35z

Therefore, when we subtract 4x - 10y + 15z from 5x + 8y - 20z = -x - 18y + 35z.

Answer:

$150

Step-by-step explanation:

The area of the lawn is 12m so 12 x 12.50 is 150. It would cost $150

Answer:

Part A.

k= 25

p= 44% = 0.44

n= 50

P(x = k) = (nk) p^k (1 - p) ^n - k

P(x = 25) = (50 25) (0.44)^25 (1 - 0.44) ^50 - 25

50!/25!(50 - 25)!

50!/25!(25)! = 1.264106 x 1014

P(x=25) = (1.264106 x 1014)(0.44)^25(0.56)^25

= 0.07812

= 7.8% probability that exactly 25 students have type O blood

Part B.

Do the same math you did above. Just replace 25 with 26 and 27 :)

25 = 7.8% probability

26 = 0.01851

 = 1.8% probability

27 = 0.00405

 = 0.4% probability
