Help ?? Anyone and how

Answer:

I hope this will help u

Step-by-step explanation:

Each interior angle of a regular polygon = 140 deg. So each exterior angle of the regular polygon = 180-140 = 40 deg. Hence the regular polygon has 360/40 = 9 sides.

It is the 2nd graph. The graph that passes through x=3 and y=3.

Step-by-step explanation:

Answer: x=28, y=14

Step-by-step explanation:

This article gives the formula for finding the sides of a 30-60-90 triangle. https://blog.collegevine.com/complete-guide-30-60-90-triangle/

The gist of it is that the hypotenuse is 1, the short side is 2, and the long side is root3. Since there was a 14 with the root3, I multiplied the 1 and 2 for the other sides by 14 to get 28 and 14.

Answer:

  10 ft

Step-by-step explanation:

The midsegment length is the average of the other two lengths.

  (QR +PS)/2 = TU

  QR +PS = 2×TU . . . . . . . . . . . . . . . multiply by 2

  QR = 2×TU -PS = 2(14 ft) -18 ft . . . subtract PS; substitute given values

  QR = 10 ft

Answer:

[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]

Step-by-step explanation:

We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.

The volume for a cone is given by:

[tex]\displaystyle V=\frac{1}{3}\pi r^2h[/tex]

Where r is the radius and h is the height.

Since the diameter is 14, the radius is 7.

And we are given that the height is 15.

Therefore, the volume will be:

[tex]\displaystyle V=\frac{1}{3}\pi (7)^2(15)[/tex]

Use a calculator:

[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]

The volume of the cone is approximately 769.7 cubic inches.

Answer:

[tex]n_x = -4n_{x-1}\\[/tex]

where [tex]n_1[/tex] = 2

Step-by-step explanation:

512/-8 = -64

difference of n = 3

[tex]\sqrt[3]{64} = 4[/tex]

[tex]n_x = -4n_{x-1}\\[/tex]

where [tex]n_1[/tex] = 2

Answer:

8.2

Step-by-step explanation:

area=b*h

37.72=b*4.7

b=37.72/4.7

=8.2

Answer:

Step-by-step explanation:

Area of parallelogram= base×perpendicular height

37.72m²=base×4.6m

base= 37.72m²/4.6m²

base= 8.2m

The answer is 6.252 pounds.

2 1/2 as a decimal is 2.5, and 15 ounces is equal to 0.938 pounds. Since there are 4 notebooks, you multiply 0.938 by 4, which is 3.752. Now, you just add 2.5+3.752=6.252

Answer:

301.59

Step-by-step explanation:

Given:

Shift of 3 units to the left 4 units down.

To find:

The transformation rule.

Solution:

The rule of transformation is

[tex](x,y)\to (x+a,y+b)[/tex]          ...(i)

Here, a<0 if the figure shifts a units left and a>0 if the figure shifts a units right.

Similarly, b<0 if the figure shifts b units down and b>0 if the figure shifts b units up.

If a transformation represents shift of 3 units to the left 4 units down, then a=-3 and b=-4.

Putting a=-3 and b=-4 (i), we get

[tex](x,y)\to (x+(-3),y+(-4))[/tex]

[tex](x,y)\to (x-3,y-4)[/tex]

Therefore, the correct option is B.

Answer: x = 0

Step-by-step explanation:

Subtract 6x^3+29x^2+47x+28 from both sides:

(2^2 + x + 4) (x - 7) - 6x^3+29x^2+47x+28

(6x^3+29x^2+47x+28)-6x^3+29x^2+47x+28

= -4x^3 - 14x^2 - 36x = 0

Now factor the left side:

-4x^3 - 14x^2 - 36x = 0

(-2x) (2x^2 + 7x + 18) = 0

Now set the factors equal to 0

-2x = 0 or 2x^2 + 7x + 18 = 0

x = 0

Answer:

The mean average of all "six" students is 36.83.

Step-by-step explanation:

Mean:

The mean is the sum of all scores divided by the number of scores.

A group of five students have a mean test score of "34.2." Another student has a score of 50.

This means that the sum is given by:

[tex]S = 5*34.2 + 50 = 171 + 50 = 221[/tex]

What is the mean average of all "six" students?

Sum of 6 students is 221. So

[tex]M = \frac{221}{6} = 36.83[/tex]

The mean average of all "six" students is 36.83.

Answer:

y = 4; x = 11/4

Step-by-step explanation:

4x - 5y = -9

-4x + y = -7

Add the two equations to eliminate x:

-4y = -16

-4y/-4 = -16/-4

y = 4

Plug in y for x

4x - 5y = -9

4x - 5(4) = -9

4x - 20 = -9

4x = -9 + 20

4x = 11

4x/4 = 11/4

x = 11/4
