Answer:
4 cm
Step-by-step explanation:
Perimeter = 18cm
θ = 2.5 radian
s = rθ, s = Arc length
Perimeter of Sector, P = arc length, s + 2r
Perimeter = rθ + 2r
r = Radius
18cm = r(2.5) + 2r
18cm = 2.5r + 2r
18cm = 4.5r
r = 18 /4.5
r = 4
I don't see the steps, but the steps that I use are:
1. Multiply the denominator by the whole number
2. Then you add the numerator to your sum.
3. The number that you just got by doing those steps is now going to be your numerator and your old denominator is going to stay your denominator.
Example:
2 2/3
3*2=6
6+2=8
8/3 is your new answer.
The answer should be 5 over 4
Answer:
r=4.5 I hope this helped!
Step-by-step explanation:
The number of servings of pasta were in the dish Lois made is 31.67.
<h3>Unit value</h3>
- Number of cups of pasta Lois made = 6 1/3 cups
- A serving of the pasta = 0.2 cups
Number of servings of pasta were in the dish Lois made = Number of cups of pasta Lois made / A serving of the pasta
= 6 1/3 ÷ 0.2
= 19/3 ÷ 0.2
= 19/3 × 1/0.2
= (19×1) / (3 × 0.2)
= 19/0.6
= 31.6666666666666
Approximately,
Number of servings of pasta were in the dish Lois made is 31.67 servings
