Answer:

nonagon/enneagon

Step-by-step explanation:

Let n be the number of length of the polygon

(n-2)x180 = 140n

180n - 360 = 140n

n = 9

The name of the polygon is call nonagon/enneagon

Answer:

See attachment for triangle

Step-by-step explanation:

Given

[tex]Side\ 1 =24[/tex]

[tex]Side\ 2 =17[/tex]

[tex]Side\ 3 =9[/tex]

Required

Draw a triangle that represent the given sides

No template is given. So, I will draw the triangle from scratch

But first, we check if the given sides are valid for a triangle (using triangle inequality theorem).

This states that:

[tex]Side\ 1 + Side\ 2 > Side\ 3[/tex]

[tex]Side\ 3 + Side\ 2 > Side\ 1[/tex]

[tex]Side\ 1 + Side\ 3 > Side\ 2[/tex]

All three inequalities must be true.

Substitute values of each side in the three inequalities

[tex]24 + 17 > 9[/tex] --- True

[tex]9 + 17 > 24[/tex] --- True

[tex]24 + 9 > 17[/tex] --- True

Since the sides are valid, then the triangle can be drawn (See attachment for triangle)

Question:

Karina has recently begun kickboxing and purchased training equipment as modeled in the diagram below. The cylindrical base is 15 inches tall with a diameter of 22 inches.

Karina wants to fill the base so that it is 85% full. What is the volume of the base that she is filling? (Find 85% of the volume).

Answer:

[tex]Section = 4847.3205\ in^3[/tex]

Step-by-step explanation:

Given

[tex]h = 15in[/tex] -- height

[tex]d = 22in[/tex] -- diameter

Required

85% of the volume

First, calculate the radius

[tex]r = \frac{1}{2} * d[/tex]

[tex]r = \frac{1}{2} * 22= 11in[/tex]

The volume (V) is then calculated using:

[tex]V = \pi r^2h[/tex]

[tex]V = 3.142* 11^2 * 15[/tex]

[tex]V = 5702.73\ in^3[/tex]

85% of the volume is:

[tex]Section = 85\% * V[/tex]

[tex]Section = 85\% * 5702.73\ in^3[/tex]

[tex]Section = 4847.3205\ in^3[/tex]

Answer:

The answer above me is correct.

Answer:

(x−2)(x−3)

Step-by-step explanation:

x²−5x+6

number = x-y = -5

x*y=6

-2+-3 = -5

-2*-3 = 6

we get

(x-2)(x-3)

Answer:

(x−2)(x−3)

Answer: x=3,x=2: (x-3)(x-2)

Step-by-step explanation: Lets factor. What two numbers multiply to get 6 and add to get 5.

The two numbers are 3 and 2 so lets start factoring.

First since its not a perfect square trinomial we know it wont be something squares.

We put (x  ?)(x   ?) the question marks are numbers that will go in so the two numbers are 3 and 2 and since the sign in front of the 5x is a minus sign both numbers will be negative. So we would do (x   3)(x   2) and both signs would be negative so we get (x-3)(x-2)

Step-by-step explanation:

Plato

This relationship represents between f(x) and g(x) :

(g•f)(x) = 5xlog(5x) + 4log(5x) which is correct option(D).

The function is defined as mathematics expression defines a relationship between one variable and another variable.

f(x) = log(5x)

g(x) = 5x + 4

Multiply by f(x) in g(x),

(g•f)(x) = (5x + 4)f(x)

(g•f)(x) = 5xf(x) + 4f(x)

Substitute value of f(x),

(g•f)(x) = 5xlog(5x) + 4log(5x)

Answer: P=2300 (1- 0.05)^x

Step-by-step explanation:

Answer:

So first what I do is I list the factors of 24 and 32. So for 24, I would write 1, 2, 3, 4, 6, 8, 12, and 24. Then for 32, I would write 1, 2, 4, 8, 16, and 32.  Finally, I would look through both lists and try to find the greatest number in common, which would be 8.

Step-by-step explanation:

Answer:

Company A = $13

Company B = $12.73

Company B

Step-by-step explanation:

To determine the unit cost for each company, divide the price of chocolate by the number of pounds

Unit cost = price ÷ total pounds offered

Company A

$32.50 ÷ 2 1/2

$32.50 ÷ 5/2

$32.50 x 2/5  = $13

Company B

$35 ÷ 2 3/4

$35 ÷ 11/4

$35 X 4/11 = $12.73

$12.73 is less than $13. Company b has a lower price per pound

Answer:

16 ft

Step-by-step explanation:

The equation is a^2+b^2=C^2

a= 30^2 = 900

b= we need to find

c= 34^2=1156

so the equation looks like this so far

900 + B^2 = 1156

we are going to subtract 900 so B^2 can be alone

1156 - 900 = 256

Now the equation looks like =

B^2 = 256

now we square root 256  

which gives you 16

B = 16

Answer:

Let's talk through this a one step at a time.

*Since f(x) is concave-up with its vertex on the x-axis, we know f(x) ≥ 0.

*We also know that when we shift a function's domain by a positive number, we shift the function left and when we shift a function's domain by a negative number, we shift the function right. So f(x-5) is f(x) shifted to the right by 5.

*At this point, f(x-5) has its vertex at (5,0).

*When we negate f(x-5), the parabola becomes concave down yet the vertex remains at (5,0). Now we're at -f(x-5). At this point we have -f(x-5)≤0 with a range (-∞,0]

*If we add 2 to create g(x)=2-f(x-5), then we have a concave down parabola with its vertex shifted up by 2, at (5,2). So, g(x) is concave down with its vertex at (5,2). Hence

Answer: 51 minutes

Step-by-step explanation:

Firstly, Pete spent 3 hours reading. Bill spent 47 minutes less than Pete reading so Bill spent:

= 3 hours - 47 minutes

= 2 hours 13 minutes

If Bill spent 2 hours 13 minutes reading and Timothy spent 1 hour 22 minutes less than this, the amount of time that Timothy read for was:

= 2 hours 13 minutes - 1 hour 22 minutes

= 51 minutes

Answer:

4500 miles

Step-by-step explanation:

750 rounded to the nearest hundred is 800. 2,488 rounded to the nearest hundred is 2,500. 155 rounded to the nearest hundred is 200. 1,015 rounded to the nearest hundred is 1,000. So 800+2,500+200+1,000= 4,500

Answer:

x = 9.8

Step-by-step explanation:

to find x, use pythagorean theorem

[tex]a^{2} = c^{2} - b^{2}[/tex]

[tex]a^{2} = 14^{2} - 10^{2}[/tex]

[tex]a^{2} = 196 - 100[/tex]

[tex]a^{2} = 96[/tex]

[tex]\sqrt{a^2} = \sqrt{96}[/tex]

[tex]a = 9.7979[/tex] ⇒ 9.8

Answer:

The value of x=4√6cm or √96cm

Step-by-step explanation:

According to Pythagoras theorem,

Hypotenuse²=Perpendicular²+Base²

H²=P²+B²

Hypotenuse given=14cm

Base=10cm

Perpendicular=x

14²=P²+10²

196=P²+100

196-100=P²

96=P²

√96=P

4√6cm=x

Answer:

6.67 yards

Step-by-step explanation:

20 feet. The builder asks him to give the measurements in yards. What will be the length in yards?

Please note that:

1 foot = 0.333 yard

20 feet = x yards

Cross Multiply

1 foot × x yards = 20 feet × 0.333 yards

x yards = 20 feet × 0.333 yards/1 foot

x yards = 6.66667 yards

Approximately = 6.67 yards

Therefore, the measurements in yards is 6.67 yards.
