The radii of two concentric circles are 9cm and 6cm respectively. Find the area of the space between the two circles.

Answers

Answer:

Step-by-step explanation:

Area of a circle = pir^2

Big one= pi(9)^2=254.34
Small one= pi(6)^2=113.04

Now minus small one from big one

254.34-113.04=141.3 cm^2

So your answer is 141.3 cm^2

7/52 as a mixed number

Answers

Answer:7

Step-by-step explanation:

Answer:

[see below]

Step-by-step explanation:

[tex]\frac{7}{52}[/tex] is a proper fraction. Therefore, it cannot be written as a mixed number.

If you meant [tex]\frac{52}{7}[/tex]:

7 can go into 52 7 times with 3 'parts' remaining.

This means that 7 is the whole number and the fraction is 3/7.

[tex]\frac{52}{7}=7\frac{3}{7}[/tex]

Hope this helps.

Answer:

[tex]1 + \frac{3}{x} [/tex]

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

[tex] \frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x} [/tex]

2) use difference of squares: a² - b² = ( a + b ) (a - b).

[tex] \frac{(x + 3)(x - 3)}{ {x}^{2} - 3x} [/tex]

3) Factor out the common term x.

[tex] \frac{(x + 3)(x - 3)}{ x(x - 3)} [/tex]

4) Cancle out x - 3 .

[tex] \frac{x + 3}{x} [/tex]

5) Simplify.

[tex]1 + \frac{3}{x} [/tex]

A cyclist cycles a distance of 44 miles in a time of 4 hours.
What is her average speed?

Answers

Answer:

11 miles an hour

Step-by-step explanation:

44 miles divided by 4 hours would equal 11 miles in one hour, meaning her average speed would be 11 miles an hour

Answer:

The average speed is 11

Step-by-step explanation:

You would have 44 on top and 4 on the bottom(44/4)

then you would divide the 4 by four and the 44 by four to get 11 miles an hour.

Answers

Answer:

C = 39

Step-by-step explanation:

From the question given above, the following data were obtained:

A = 2x + 108

B = x + 33

C =?

Next, we shall obtain an expression for C. This can be obtained as follow:

A + B + C = 180 (sum of angles in a triangle)

2x + 108 + x + 33 + C = 180

2x + x + 108 + 33 + C = 180

3x + 141 + C = 180

Make C the subject by rearranging

C = 180 – 141 – 3x

C = 39 – 3x

Next, we shall determine the value of x. This can be obtained as follow:

A = 2x + 108

B = x + 33

C = 39 – 3x

A + B + C = 180

2x + 108 + x + 33 + 39 – 3x = 180

2x + x – 3x + 108 + 33 + 39 = 180

3x – 3x + 180 = 180

3x – 3x = 180 – 180

3x – 3x = 0

x(3 – 3) = 0

x(0) = 0

x = 0

Finally, we shall determine C. This can be obtained as follow:

C = 39 – 3x

x = 0

C = 39 – 3(0)

C = 39 – 0

C = 39

Heather has a rectangular yard, she measures it and finds out it is 24 1/2 feet long by 12 4/5 feet wide. She wants to know how many square feet of sod she will need to cover her yard. How much did will she need and if each square inch of sod cost 65 cents how much will she pay to cover her yard?

Answers

Answer: $2,446.08

Step-by-step explanation:

Lets convert the length and width into decimal form so it's easier to understand.

24 1/2= 24.5

12 4/5= 12.8

Now we must multiply to get the area. 24.5x12. 8= 313. 6 ft

Each square inch costs .65 so we must multiply .65 by 12 to see how much a foot costs. 12x0.65= 7.8

Now that we know how much each foot cost lets multiply 313.6 by 7.8. 313.6x 7.8= $2446.08

The measures of the exterior angles of a heptagon are xº, 2x°, 4x°, 6x°, 8x°, 9x°
and 10x°. Solve for x.

Answers

Answer:

the sum of exterior angle of a polygon is always 360 degree.

therefore,

xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°

40x = 360°

x = 360/40 = 9

x = 9

The sum of the exterior angles of a polygon is 360 degrees, so the value of x is 9

The exterior angles of the polygon are given as:

xº, 2x°, 4x°, 6x°, 8x°, 9x° and 10x°

The exterior angles of a polygon add up to 360 degrees.

So, we have:

[tex]x\º+ 2x\°+ 4x\°+ 6x\°+ 8x\°+ 9x\° +10x\° = 360\°[/tex]

Evaluate like terms

[tex]40x\° = 360\°[/tex]

Divide both sides of the equation by 40

[tex]x\° = \frac{360\°}{40}[/tex]

Divide 360 by 40

[tex]x\° = 9[/tex]

Rewrite as:

[tex]x = 9\°[/tex]

Hence, the value of x is 9

Answer:

y = 6x + 4

Step-by-step explanation:

The point-slope form of the equation that describes the line with a slope of m and including the point (x₀, y₀) is: y - y₀ = m(x - x₀)

m = 6

(1, 10) ⇒ x₀ = 1, y₀ = 10

Therefore:

y - 10 = 6(x - 1) ← the point-slope form

y - 10 = 6x - 6 {add 10 to both sides}

y = 6x + 4 ← the slope-intercept form

The angle measurements in the diagram are represented by the following expressions.
A = 8x+ 78°
B = 2x + 114
B=

Answers

Since angle A and B are interior angles, we can set them equal to each other. So then we can solve for x and plug x in for B.
1) 8x + 78 = 2x + 114
2) 8x - 2x = 114 - 78
3) 6x = 36
4) 6x / 6 = 36 / 6
5) x = 6
Now we can plug in x to equation b
1) 2(6) +114
