Answer:
1/4
Step-by-step explanation:
In total Jessica has 12 things in her pocket and 3 are acorns so if she just pulls one thing out there is a 3/12 chance that it will be an acorn which we can reduce to 1/4

Answer: 2w = 16
Step-by-step explanation:
From the question, we are informed that Luis walked for 16 minutes while Natalie walked for w minutes and that Luis walked twice as long as Natalie.
The number of minutes that Natalie walk will be:
2 × w = 16
2w = 16
Solving further will be:
2w = 16
w = 16/2
w = 8
Natalie walked for 8 minutes
- 2(3) + 22 - 8 - 2=
-6 + 12 =
6
3 + 3 + 3 + 3 + 3 = 15
3 x 3 x 3 x 3 x 3 = 3^5 (because there are 5 threes multiplied together)
-2x^3 + 22 - 8 - 2 =
-2x^3 + 12
hope this helps
We will use the circumference formula to find the radius and then multiply it by 2 to find the diameter.
C = 2πr
31.4 = (2)(3.14)(r)
31.4 = 6.28r
5 = r
So our radius is 5 in.
We can multiply it by 2 to get the diameter.
5*2 = 10
So the diameter is 10 inches
