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:

  a = -2, h = 2, k = 1

Step-by-step explanation:

Compare the expressions. Match one pattern to the other.

  [tex]f(x)=-2|x-2|+1\\\\f(x)=\ \,\,a|x-h|+k \qquad\ a=-2,\ h=2,\ k=1[/tex]

__

The transformations are ...

  Translation by (h, k) = (2, 1). That is, 2 units right and 1 unit up.

  Vertical scaling by "a", which is (i) reflection over the x-axis (because a < 0), and (ii) expansion by a factor of 2.

Answer:

Percent [wearing elf costume] = 60%

Step-by-step explanation:

Given:

Total number of people = 50

Grinch or elf costume = 40

Grinch costume = 10

Find:

Percent [wearing elf costume]

Computation:

Percent [wearing elf costume] = [Grinch or elf costume - Grinch costume] / Total number of people

Percent [wearing elf costume] = [40-10] / 50

Percent [wearing elf costume] = [30] / 50

Percent [wearing elf costume] = 60%

Answer:

(1) x= −1 /2 y+ 5 /2

(2) x= −1 /2 y−2

Step-by-step explanation:

(1) 2x+y=5

Step 1: Add -y to both sides.

2x+y+−y=5+−y

2x=−y+5

Step 2: Divide both sides by 2.

2x /2 = (−y+5)/2  

x= −1 /2 y+ 5 /2

(2) Step 1: Flip the equation.

−2x−4=y

Step 2: Add 4 to both sides.

−2x−4+4=y+4

−2x=y+4

Step 3: Divide both sides by -2.

−2x /−2 = (y+4) /−2

x= −1 /2 y−2

The perimeter of the isosceles right triangle is P = 6 + 3√2 feet

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle

The three types of Isosceles Triangles are :

Isosceles acute triangle

Isosceles right triangle

Isosceles obtuse triangle

Given data ,

Let the isosceles triangle be represented as ΔABC

In an isosceles right triangle, the two legs are congruent, so if one leg has a length of 3 ft, then the other leg also has a length of 3 ft. Let's call the length of the hypotenuse h.

Using the Pythagorean theorem, we can find the length of the hypotenuse:

h² = 3² + 3²

h² = 18

Taking square roots on both sides , we get

h = 3√2 feet

The perimeter of the triangle is the sum of the lengths of its sides:

Perimeter = 3 + 3 + 3√2 = 6 + 6 + 3√2 feet

Hence , the perimeter is 6 + 3√2 feet

Step-by-step explanation:

distribute 3 to 4x+2 --> 12x + 6 = 8x + 24 - 2x

combind like terms --> 12x + 6 = 6x + 24

subtract 6 from both sides --> 12x +6 -6 = 6x + 24 - 6 --> 12x = 6x + 18

subtract 6x from both sides --> 12x - 6x = 6x -6x +18 --> 6x = 18

divide both sides by 6 to get what x equals --> x = 3

Answer:

x - 3y = -27

Step-by-step explanation:

Two parallel lines have equations of the same form; only the constants differ.

Thus, if the given line is x - 3y = 1, the desired new line has equation of the form x - 3y = C, where we must find the value of C.

Substituting 3 for x and 10 for y in x - 3y = C, we get    3 - 3(10) = C, or

3 - 30 = C.  Thus, C = -27 and the desired new line is    x - 3y = -27.  

Answer:

Arielle has 374 grasshoppers and 187 crickets

Step-by-step explanation:

Let's set:

x = number of grasshoppers

y = number of crickets

Arielle has a collection of 561 insects, thus:

x + y = 561            [1]

The number of grasshoppers is twice the number of crickets, thus:

x = 2y                   [2]

Substituting [2] in [1]:

2y + y = 561

Simplifying:

3y = 561

Dividing by 3:

y = 561/3

y = 187

From [2]:

x = 2*187 = 374

x = 374

Arielle has 374 grasshoppers and 187 crickets

The new coordinates of point A would change as follows:

5/4

1 1/4

Step-by-step explanation:

The dimensions of rectangle A are L=12 and W=8. The dimensions of rectangle B are L=15 and W=10.

We are told rectangle B is a copy of rectangle A, thus we must find the scale factor by dividing both dimensions:

15/12=5/4

10/8 =5/4

Dividing 5/4 we get 1.25.

Converting 5/4 to mixed fraction: 5/4= 1 1/4

The line of best fit is y = 1.383x - 1.526 after calculating using the table, and option (c) y = 1.383x - 1.526 is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

As we know, the regression line is a graph that illustrates the pattern of a group of statistics. In other words, it shows the data's best pattern.

We have data shown in the table:

We can find the line of best fit by the formula.

Let y = mx + c

m is the slope of the line of best fit and the y-intercept is c.

After calculating:

m = 1.383

c = -1.526

y = 1.383x - 1.526

Thus, the line of best fit is y = 1.383x - 1.526 after calculating using the table, and option (c) y = 1.383x - 1.526 is correct.

Answer:

A. y = 8x

Step-by-step explanation:

y is the product, and x is one of the variables that will multiply another number to equal y. So x times a variable equals y, then y divide by x would equal that variable. And in the questions it gave us if y = 48 and x = 6. So we'll use that: 48/6 = 8, the variable is 8. 8 times 6 equals 48 so:

y = 8x
