Answer:
<h2>132.25π m²</h2>
Step-by-step explanation:
The circumference of a circle is 23π
On the other hand, The circumference of a circle = 2×π×r ; where r is the radius.
then
by equating the last two expressions we get: 23π = 2πr then r = 23/2
then
the area = π × r² = (23/2)²×π = (132.25)×π
The answer is:
Square root of 77
—————————
22
You need to rationalize the denominator meaning that you have to get rid of the square root signs in denominator
To get rationalize the denominator you need to multiply both sides by square root of 11
(Square root of 7)(square root of 11)
——————————————————
2(square root of 11)^2
When squaring a square root it makes the square root “go away”
(Square root of 77)
——————————
2(square root of 11^2 or 122) = 2(11)
So:
The answer is
square root of 77
—————————
22

The answer for the question in problem would be $125 is the price of hotel per night. This is computed by establishing the equations from the given statements, 3x + 4y = 625 and 4x +5y = 875. And by substitution you would get the answer of 125 as the price per night n the hotel and 75 per day for the rental of car.
