Answer:

528.6

Step-by-step explanation:

find the circumference of the circle using:

πd: 22/7*74

add the length of the 4 strokes: 37*8

add the two:

Answer:

528.48cm

Step-by-step explanation:

Total length of all the spokes

37cm*8 = 296cm

Length of the circular rim

2πr = Circumference

2(37)π = 74π

74π = 232.48cm

Overall Length

232.48cm + 296cm = 528.48cm

Answer:

We start with the equation:

(x^2 - 1)/(x + 1) = 2

We want to rewrite this in standard form.

We can multiply both sides by (x + 1) to get:

((x^2 - 1)/(x + 1))*(x + 1) = 2*(x + 1)

x^2 - 1 = 2*(x + 1) = 2*x + 2

Now we can move all the terms to one side to get:

x^2 - 1 - 2 - 2*x = 0

x^2 - 2*x - 3 = 0

And this is a standard quadratic equation, that we can solve by using the Bhaskara's formula, this will give us the solutions:

[tex]x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4*1*(-3)} }{2*1} = \frac{2 \pm 4}{2}[/tex]

Then the two solutions are:

x = (2 + 4)/2 = 3

x = (2 - 4)/2 = -1

Answer:

1

Step-by-step explanation:

We plug in 4 for m and 1/2 for n.

[tex]\frac{4}{8(\frac{1}{2}) }[/tex] = [tex]\frac{4}{4}[/tex] = 1

Answer:

b

Step-by-step explanation:

A collection of all points in the plane of the form [tex](x, f(x))[/tex] is the graph of a function f. The graph of f is defined as the graph of the equation [tex]y = f(x)[/tex].

Graph

[tex]\to[/tex] f(x)=|3x−4|

[tex]\to[/tex] f(x)+3 =?

putting the [tex]f(x)[/tex] value into the [tex]f(x)+3[/tex] and calculate the given value:

[tex]\to[/tex] |3x-4|+3

[tex]\to[/tex] 3x-4+3

[tex]\to[/tex] 3x-1

Therefore, the final answer is "Option B".

Answer:

Line A

Step-by-step explanation:

Line A is the line of best fit because it intersects the point (10,3) on the graph while the others do not.

Answer:

Circumference =

Step-by-step explanation:

The equation for finding the circumference of a circle is: C=2πr

All we need to do is plug in for r of the equation (which is the radius) and solve.

C = 2(3.14)·12

C = 6.28 · 12

C = 75.36 mill.

That is the circumference.

Answer:

9 : 2 : 4

Step-by-step explanation:

Given

72 : 16 : 32 ( divide each part of the ratio by 8, the LCM of 72, 16, 32 )

= 9 : 2 : 4

Answer:

Step-by-step explanation:

Answer:

8 cm

Step-by-step explanation:

[(x+5)*2.5]/2 =  16.25

(x+5)*2.5 = 32,5

2.5x + 12,5 = 32,5

2.5x = 20

x = 8

Answer:

Answer:

y=15

Step-by-step explanation:

Answer:

y=15

Step-by-step explanation:

To find y:

8y=120 –––Divide both sides by 8 so you can get y alone

y=15

Answer:

Pam 6

Tia 8

Veronica 11

Lily 15

Step-by-step explanation:

Tia's age = 8

Pam's age = Tia's age - 2

8 - 2 = 6

Veronica = pam's age + 5

6 + 5 = 11

Lily's age = veronica's age + 4

11 + 4 = 15

Answer:

1. 168 cm^{2}

2. 156 in^{2}

3. 30 cm^{2}

4. 360 ft^{2}

Step-by-step explanation:

All ratio questions. We can set up proportions then cross multiply

1. \frac{8}{12} \frac{112}{x}

8x = (112 x 12)

8x = 1344

x = 168m

2.\frac{4}{8} \frac{78}{x}

4x = (78 x 8)

4x = 624

x = 156in

3. \frac{5}{2} \frac{75}{x}

5x = (75 x 2)

x = 30cm

4. \frac{8}{10} \frac{288}{x}

8x = ( 288 x 10 )

8x = 2880

x =360ft

Answer:

14 mm

Step-by-step explanation:

perimeter of a square is a + b

and all sides are equal to each other since its a square

therefore it is 14 mm each

Answer:

See attachment for number line

Step-by-step explanation:

Given

[tex]Ian = \frac{6}{8}[/tex]

[tex]Anna = \frac{3}{4}[/tex]

Required

Number line to represent both amounts

The interval on the number line is 16.

So, we need to calculate the position of both as thus.

[tex]Ian = \frac{6}{8} * 16 = \frac{96}{8} = 12[/tex]

[tex]Anna = \frac{3}{4} * 16 = \frac{48}{4} = 12[/tex]

So, both will be positioned on the 12th position.

The yellow dot represents Anna while the blue dot represents Ian

Answer:

the answer is -29

Step-by-step explanation:

Hope this helps have a good rest of your day :)

Answer:

I think its -15

Step-by-step explanation:

you take -7 and add it to -22 but since it's a negative + a negative it should equal a positive so you just normally subtract -7 from -22 and get -15

Answer:

it would be 20 ( I am pretty sure this is correct )
