Answer:

r = 8.5 inches

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

17 pi = 2 * pi *r

Divide each side by 2 pi

17 pi / ( 2pi) = 2 * pi r/ ( 2 pi)

17/2 = r

8.5 = r

The answer is 8.5 inches.

Answer:

12.9x-9

Step-by-step explanation:

add 5.3x and 7.6x

Answer:

12.9x-9

Step-by-step explanation:

First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self because there's no other like terms.

More examples -

5.3x+−9+7.6x

Combine Like Terms:

=5.3x+−9+7.6x

=(5.3x+7.6x)+(−9)

=12.9x+−

Answer:

d

Step-by-step explanation:

at x =-1,1 there is a vertical asymptote.

The rational function which is graphed below is f(x)= x/ (x-1)(x+1).

A curve or line that serves as the boundary of another curve or line.

From the graph of the function we see that the graph has vertical asymptote at x=1 and x= -1.

The scenario in which the first two characteristics are true is f(x)= x/ (x-1)(x+1).

Making 'b' the subject of formula gives b = a² - 6

It is important to note that the subject of formula is described as a variable that is made up to stand alone in an equation.

The subject of formula is the variable that is worked out on on side of the equation sign.

From the information given, we have the equation;

a = [tex]\sqrt{(b + 6)}[/tex]

To make 'b' the subject of formula, we take the following steps;

Find the square of both sides, we get;

a² = [tex](\sqrt{(b + 6)} ^2[/tex]

Cancel out the square, we get;

b + 6 = a²

collect the other terms on one end of the equation, we have;

b = a² - 6

Hence, the equation is b = a² - 6

Answer:

C. (4 , 3)

Step-by-step explanation:

We are given a system of equations and are asked to find its coordinate value.

To solve, we can keep in mind that both start with y, therefore meaning that we can replace one of the y's with one of the equations.:

[tex]y=\frac{1}{4}x+2\\y=x-1[/tex]

[tex]\frac{1}{4}x+2 = x-1[/tex]

Let's try to get x alone, first subtract 2 from both sides:

[tex]\frac{1}{4}x=x-3[/tex]

Now subtract x from both sides:

[tex]-\frac{3}{4}x=-3[/tex]

Now since the denominator is 4, multiply both sides by 4:

[tex]-3x=-12[/tex]

Lastly, divide both sides by -3 to get x :

[tex]x=4[/tex]

Now that we know x is 4, we can substitute 4 for x in both equations:

[tex]y=\frac{1}4(4)+2\\y=(4)-1[/tex]

[tex]y= 3\\y= 3[/tex]

Y is equal to 3, therfore, our coordinate value is C. (4,3)

Answer:

Width: 16 in.,  Length:  18 in.

Step-by-step explanation:

Consecute even/odd problems seem a bit weird at first.

You choose a variable to represent the first integer, say  n .  Assume it's even (no symbolic way to tell!).  If  n  is even, then the next consecutive integer is  n + 2.  You add two because you want to skip one integer.

Width:  n

Length:  n + 2

Area is length multiplied by width, so

[tex]n(n+2)=224\\\\n^2+2n=224\\\\n^2+2n-224=0\\\\(n+14)(n-16)=0\\\\n+14=0 \text{ or } n-16=0\\\\n=-14 \text{ or }n=16[/tex]

The negative solution makes no sense, so use n = 16

Width: 16

Length: 18

Answer:

Step-by-step explanation:

Given,

Parallel sides of the trapezium = 3in, 7in

Height of the trapezium = 5in

Therefore,

Area of the trapezium

[tex] = \frac{1}{2} \times sum \: of \: parallel \: sides \times height[/tex]

[tex] = \frac{1}{2} \times (7 + 3)in \times 5in[/tex]

[tex] = \frac{1}{2} \times 10in \times 5in[/tex]

= 5in × 5in

[tex] = {25in}^{2} [/tex]

Hence,

Area if the trapezium is 25 square inches (Ans)

[tex]S_\square = 8 * 8 = 64\\S_\triangle = \frac{ah}{2} = \frac{8*3}{2} = 4 * 3 = 12\\S = S_\square - S_\triangle = 64 - 12 = 52[/tex]

Answer:

  67 million square miles

Step-by-step explanation:

The area of a sphere is given by ...

  A = 4πr²

So the area of the Earth is approximately ...

  A = 4π(4000 mi)² ≈ 2.01×10^8 mi²

The area of the 1/3 that is not covered by water is approximately ...

  (2.01×10^2 mi²)/3 = 6.7×10^7 mi²

The land area is estimated to be about 67 million square miles.

Answer:

B. AC = 22, BC = 22, AB = 44

C. AC = 30, BC = 30, AB = 60

Step-by-step explanation:

B.

[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)

[tex] \therefore AC = BC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)

[tex] \therefore 2x - 6 = x + 8[/tex]

[tex] \therefore 2x - x= 6 + 8[/tex]

[tex] \therefore x= 14[/tex]

[tex] AC = 2x-6=2(14)-6=28-6= 22[/tex]

[tex] BC= x + 8=14 + 8= 22[/tex]

AB = AC + BC = 22 + 22 = 44

C.

[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)

[tex] \therefore BC = AC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)

[tex] \therefore 7x-5=4x+10 [/tex]

[tex] \therefore 7x - 4x= 5 + 10[/tex]

[tex] \therefore 3x= 15[/tex]

[tex] \therefore x= \frac{15}{3}[/tex]

[tex] \therefore x= 5[/tex]

[tex] AC = 4x+10=4(5)+10=20+10= 30[/tex]

[tex] BC= 7x - 5=7(5)-5=35-5= 30[/tex]

AB = AC + BC = 30 + 30 = 60

Answer:

The correct answer is "The volume of the pyramid is one-third the volume of the prism".

Step-by-step explanation:

The formula for the volume of a rectangular prism is [tex]lwh[/tex], where [tex]l[/tex] represents length, [tex]w[/tex] represents width, and [tex]h[/tex] represents height. The formula for the volume of a rectangular pyramid is [tex]\frac{lwh}{3}[/tex], where [tex]l[/tex] represents length, [tex]w[/tex] represents width, and [tex]h[/tex] represents height. Since the base and height of the rectangular pyramid is the same as the rectangular prism, that means the volume of the pyramid is one-third of the volume of the rectangular prism.
