The circumference of a circle is 29x inches. Find the radius.

Mathematics
1 answer:
Lena [83]3 years ago
4 0

Answer:

r = \frac{29x}{2\pi }

x = \frac{2\pi r}{29}

Step-by-step explanation:

C = 2\pir

29x = 2\pir  --------- (i)

divide both sides of (i) by 2\pi

r =  \frac{29x}{2\pi }

but when you divide both sides of (i) by 29, you get

x = \frac{2\pi r}{29}

Korolek [52]

Answer:

Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951

Step-by-step explanation:

The fraction of older Americans who were included in the study and suffered broken bones during the three-year period?

This fraction = (Number of older Americans who suffered broken bones recorded during the three year period of the study)/(Total number of older Americans involved in the study)

Number of older Americans who suffered broken bones recorded during the three year period of the study = (11 from those that took the additional supplements) + (26 from those that did not take additional supplements) = 11 + 26 = 37

Total number of older Americans involved in the study = 389

Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951

Solve the system of equations by substitution y=-2x+18 and 4y-x+9=0
Stells [14]
  • Answer:

<em>x = 9</em>

<em>y = 0</em>

  • Step-by-step explanation:

<em>y = -2x + 18 </em>

<em>4y - x + 9 = 0</em>

<em />

<em>4(-2x + 18) - x + 9 = 0</em>

<em>- 8x + 72 - x + 9 = 0</em>

<em>- 9x + 81 = 0</em>

<em>81 = 9x</em>

<em>x = 81 : 9</em>

<em>x = 9</em>

<em />

<em>y = - 2×9 + 18</em>

<em>y = - 18 + 18</em>

<em>y = 0</em>
