Answer:
276 4/7 ft
Step-by-step explanation:
Let r1 represent the radius of the inner circle. Then its circumference in feet is ...
C = 2πr
66 = 2π(r1)
If the radius of the outer circle is (r1 +44), then its circumference is ...
C = 2π(r1 +44) = 2π(r1) +2π(44)
C = 66 +88π
Then the difference in the circumferences is ...
(66 +88π) - (66) = 88π
Using the given value of π, the difference in circumferences is ...
(88 ft)(22/7) = 1936/7 ft = 276 4/7 ft

</span>rite the decimal number as a fraction
(over 1)
49.567 = 49.567 / 1
Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's
Numerator (N)
N = 49.567 × 10 × 10 × 10 = 49567
Denominator (D)
D = 1 × 10 × 10 × 10 = 1000
N / D = 49567 / 1000
Simplifying our fraction

<span>To determine the value of the unknown number in this item, we have to let x be that number such that 0.75x is equal to 27. To calculate for the value of x, we divide 27 by 3/4. This operation gives us the value of 36. Hence, the answer to this item is 36.</span>
The new coordinates will be ( 7,5) and (11,9) , Option A is the correct answer.
<h3>What is a Reciprocal Function ?</h3>
The reciprocal function is the inverse of the function, such that 1/ f(x) is the reciprocal of f(x).
The given linear function has pairs of points
(5,7) and (9,11)
The reciprocal of this will be
interchanging of the coordinates
Therefore the new coordinates will be
( 7,5) and (11,9)
Option A is the correct answer.
