Answer:
The length of the semicircle arc is 6π
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 12
π = pi
c = π * d
we replace with the known values
c = π * 12
c = 12π
The length of the circumference is 12π
N
ow we divide the circumference by 2 and we will obtain the length of the arc of the semicircle
12π / 2 = 6π
The length of the semicircle arc is 6π
Answer:
x = √12
Step-by-step explanation:
Easy:
3x^2 = 36
Cancel out the 3 so it is only x^2; you can do this by dividing each side by 3 which gives you:
x^2 = 12
Square root the entire thing to get rid of the square and you get the answer
x = √12
First, you would need to find out how much 1 sun visor would cost. To do this, you would divide $90 among the 12 sun visors.
$90 ÷ 12 = $7.50
It costs $7.5 per sun visor.
Next, you would need to create an equation to find out how much it will cost to buy 15 more sun visors.
($7.50 × 15) + $90 = $202.50
It will cost $202.50 in total to buy 12 visors plus another 15.
Now, the last thing you would need to do is calculate how much it would cost to buy 16 sun visors.
$7.50 × 16 = $120
It would cost $120 to buy 16 sun visors.
I hope this helps!
