Answer:
7 cm
Step-by-step explanation:
An equilateral triangle has all sides equal.
To find the measure of the side, simply divide the perimeter by 3. This is because a triangle has 3 sides.
21 ÷ 3 = 7
Maybe 8? I'm not 100% sure
Answer:
a = 12. b =1/6. g(x) = 12(1/6)^x
Step-by-step explanation:
g(x) =a * b^x.
First we should use the give values to us in the table which are x=0 then g(x) = 12 and if x =1, then g(x) = 2. We should plug in the value where x = 0 since any value to the power of 0 is 1. 12= a *b^0. 12=a *1. Then we will get the value of a which is 12. Then we plug in our second given value to find b. 2 = 12 * b^1. First we will divide both sides by 12 to find b. 2/12 = 1/6. since any value to the power of 1 is itself then b =1/6. Then you will have a = 12. b =1/6 so g(x) = 12(1/6)^x
The park charges 1.50 per ride.
1. Louisa bought 15 ride tickets at 1.50 each.
Equation: C = Entry Fee + 1.50t
t = 15.
c = 30.75
30.75 = Entry Fee + 1.50(15)
30.75 = Entry fee + 22.50
Entry fee = 30.75 - 22.50
Entry fee = $8.25
2. Entry fee was calculated as 8.25 from #1.
Tickets are 1.50 each.
He can spend 22.
22 = 8.25 + 1.50t
Subtract 8.25 from both sides:
13.75 = 1.50t
Divide both sides by 1.50:
t = 13.75 / 1.50
t = 9.2
He can buy 9 tickets.
