Answer:

It will cost $39,337.92 for the piller.

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 8 m

Height of the cylinder, h = 9 m

If concrete cost $87 per cubic meter, we need to find how much the concrete cost for the pillar.

The volume of the cylinder is given by :

[tex]V=\pi r^2h\\\\=3.14\times (4)^2\times 9\\\\=452.16\ m^3[/tex]

Cost per cubic meter = $87

Cost for 452.16 m³ will be :

C = 452.16 × 87

C = $39,337.92

Hence, it will cost $39,337.92 for the piller.

Answer:

(2, 1 )

Step-by-step explanation:

Given the 2 equations

2x - y = 3 → (1)

x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by subtracting x from both sides

y = 3 - x → (3)

Substitute y = 3 - x into (1)

2x - (3 - x) = 3

2x - 3 + x = 3

3x - 3 = 3 ( add 3 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

substitute x = 2 into (3) for corresponding value of y

y = 3 - 2 = 1

Solution is (2, 1 )

Answer:

Start at the origin, then graph the point (1, 47) and connect the line.

Step-by-step explanation:

Slope: 47

y-intercept: 0

The correct answer would be -4 because -4 is equal to -4

Answer:

4x^2 + 24 = 0

4x^2 = - 24

unsqrt

4x = ±2√6

x =  (±2√6)/4

Answer:

Option B

Step-by-step explanation:

8 - 2x < 18

Subtract 8 from both sides;

-2x < 10

Divide both sides by -2

x > -5

Answer:

X > -5

it would be B.

open circle on -5 and the arrow point on the right. Because x can be any number greater than -5.

Step-by-step explanation:

8 - 2x < 18

- 2x < 18 - 8

-2x < 10

x > 10/-2

x > -5

Answer:

No

Step-by-step explanation:

We use the Pythagorean theorem.

a^2 + b^2 = c^2

7^2 + 12^2 = 49 + 144 = 193

13^2 = 169

Since 193 is not equal to 169, the triangle is not a right triangle.

Answer:It is 100 times as great in the ZIP code than it is in the area code

Step-by-step explanation:

step 1

Veronica 's uncle ZiP CODE = 89507 = The value of 5 here, represents 5 Hundred-----500

Veronica 's uncle Area code= 775 = The value of 5 here  represents 5 units--5

it will take a 100 times the value of 5 in the area code to be same as the value of 5 in the ZIP code

Step 2:

Therefore, we can say that the value of 5 is 100 times as great as the ZIP code than it is in the area code.

Answer:

The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)

Step-by-step explanation:

To find the centroid of a triangle, use this rule centroid = ([tex]\frac{x1+x2+x3}{3},\frac{y1+y2+y3}{3}[/tex]), where (x1, y1), (x2, y2), (x3, y3) are the vertices of the triangle

∵ The vertices of the triangle are (1, 1), (1, 4), (-3, 4)

∴ x1 = 1 and y1 = 1

∴ x2 = 1 and y2 = 4

∴ x3 = -3 and y3 = 4

→ Substitute them in the rule above

∵ Centroid = ([tex]\frac{1+1+-3}{3},\frac{1+4+4}{3}[/tex])

∴ Centroid = ([tex]\frac{-1}{3},\frac{9}{3}[/tex])

∴ Centroid = ([tex]-\frac{1}{3}[/tex] , 3)

∴ The coordinates of the flower bed are ([tex]-\frac{1}{3}[/tex] , 3)

Answer:

The final cost of her pizza is $11.90

Step-by-step explanation:

First we need to convert 15% into a decimal, which is 0.15.

Now we multiply $14 and 0.15.

$14 × 0.15 = $2.10.

Now we subtract $2.10 from $14.00.

$14.00 - $2.10 = $11.90
