No it is not reasonable because you need 186 inches of ribbon and 160 is not nearly enough
Tangents to a circle from the same point are equal length. Thus, for example, the two segments at the upper left (to A and to D) are both length 4. The ones at lower left are both length 6.
Then
x = 4+6
x = 10
The perimeter is twice the sum of the lengths shown, so is
perimeter = 2(4 + 8 + 3 + 6)
perimeter = 42
Answer:
Inequality: 20.50x + $17.75 ≤ $110
Solve: 4 people can go to the amusement park
Explaination:
Inequality:
$110 = Amount of money they have
$17.75 = Parking Cost
$20.50 = Cost of tickets per person
<em>Because they only have $110, they can't spend more than that amount. </em>
Therefore, the inequality would be the ticket cost per person, times the amount of people being payed for (aka x) plus the parking cost is less than or equal to the amount of money they have to spend. Hence the inequality:
<em>20.50x + $17.75 ≤ $110</em>
Solve:
$110 - $17.75 = $92.25 (92.25 is how much is left for tickets after subtracting the parking cost)
$20.50 x 4 = $82 (4 tickets can be bought for the price of $20.50)
$92.25 - $82 = $10.25 (10.25 isn't enough for another person)
So, the solution to the inequality is <em>4 people can go to the amusement park.</em>
There is no solving of this problem. This is the equation for energy-mass equivalence as derived by Albert Einstein. If you have values for different aspects there could be some solving.
