Answer:
Area = square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
Step-by-step explanation:
As we know the circumference of a circle is
The radius of the hub cap needs to be devised to determine the area
centimeters
Area of the hub cap =
Substituting the devised value of r in the above equation, we get -
square centimeter
If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
You would do 29.85 ÷ 3 which equals 9.95. You would do the in verse operation. Hope I helped you.
So if the number is positive then the opposite is negative, vice versa.
opposite of 4 is -4
opposite of -5 is 5
Answer:
a) 5s + 10a = 4500
s+a = 700
b) $2500
c) $1000
Step-by-step explanation:
a) Let students = s and adult = a
5s + 10a = 4500 -------1
s+a = 700 -------2
Using elimination metthod
Multiply eqn 2 by 5
5s + 10a = 4500
5s + 5a = 3500
Subtracting
5a = 1000
a =200
s = 700- 300= 500
b) if both tickets sell for $10 each
200*10 + 500*10 = $7000
Extra money that would have been made = 7000- 4500 =$2500
c) if s is $5 and a is $15
Tickets sold = 200*15 + 500*5 =$5500
Extra money made = $5500- $4500
= $1000
