Answer:

B. Circle B

Step-by-step explanation:

The radius of a circle is the center point of a circle to the outer side of the circle. The diameter of a circle is from one side of the circle to the other in a straight line. We can multiply the radius of circle B by 2 to get the diameter of circle B. The diameter of circle B is 10 and the diameter of circle A is 9, so the larger circle/circumference would be circle B.

the length of a rectagle is 5 in longer than its width. if the perimeter of the rectangle is 56 in, find its length and width
lisabon 2012 [21]

Answer:

Step-by-step explanation:

Let the width of the rectangle = x

As length is 5 inches longer than width, we have to add 5 to width

Length = x + 5

Perimeter of ractangle = 56 in

2* (length + width) = 56

2*( x + 5 + x) = 56

2* (2x + 5)    = 56

Use distributive property: a*(b +c) =(a*b) + (a * c)

2*2x + 2*5   = 56

4x  + 10 = 56

Subtract 10 from both sides

4x = 56- 10

4x = 46

Divide both sides by 4

x = 46/4

x = 11.5

Width = 11.5 in

length = 11.5 + 5

            = 16.5 in

HELP me with These questions 2
LUCKY_DIMON [66]

Answer: 4

<u>Step-by-step explanation:</u>

A = \frac{1}{2}r²θ

50 = \frac{1}{2}(5)²θ

100 = (5)²θ

100 = (25)θ

4 = θ

********************************************************************************

Answer: 1570.80 cm²

<u>Step-by-step explanation:</u>

A = \frac{1}{2}r²θ

A = \frac{1}{2}(100)²(\frac{\pi}{10})

A = 500π

A = 1570.80

********************************************************************************

Answer: 19.63 m²

<u>Step-by-step explanation:</u>

A = \frac{1}{2}r²θ

  = \frac{1}{2}(5)²(\frac{\pi} {2})

  = \frac{25\pi} {4}

  = 19.63

********************************************************************************

Answer: 15°

<u>Step-by-step explanation:</u>

\frac{\pi }{180} = \frac{\pi} {12x}

180 = 12x

  15 = x

********************************************************************************

Answer: A

<u>Step-by-step explanation:</u>

Quadrant I: 0° - 90°

Quadrant II: 90° - 180°

Quadrant III: 180° - 270°

Quadrant IV: 270° - 360°

255° is in Quadrant III

Explain step by step =) Harry rides his bike 25 3/8 miles. Karen rides her bike 25 2/5 miles. Who rides farther?
Alex
To answer this question we need to use subtraction. 
we need to make the denominators the same. 
In order to make them the same we need to find the least common multiple, of 8 and 5. 
The least common multiple(the smallest shared value of the two numbers) is 40. 

Next we divide our old denominator 5 by 40, which gives us 8, we multiply 8 by the numerator 2, which gives us 16. So now we have 16/20. We have to do the same to the other side. 8÷40 = 5.  5 x 3 = 15. Now we have 15/20.

Now we have a brand new equation, 16/40 - 15/40. The answer is 1/40. 
In a fraction the answer is 1/40, so Karen rides her bike further. 

In decimal form the answer is 0.025. 

I hope this helps!
