Answer:
201
Step-by-step explanation:
assuming we are finding the circumference of the outer circle or the path to find the length of the fence we start by combining the radius of the pool and the path width for the radius of the second circle around the first one. the circumference or C is equal to 2
x the radius or r you can also use the diameter or d, times for the circumference
with this info we can figure out the answer
lets say = 3.14
32 = r
r x 2 = d
d x = 200.96 rounded its 201
the circumference is 201
Answer:
Option 4
Step-by-step explanation:
Group B, because seven children have a forearm length longer than 10 inches.
Additional verification :
Finding average forearm length of Group A :
- 9(3) + 10(5) + 11(2) / 10
- 27 + 50 + 22 / 10
- 99/10
- 9.9
Finding average forearm length of Group B :
- 10(3) + 11(4) + 12(3) / 10
- 30 + 44 + 36 / 10
- 100/10
- 10
Group B clearly has the longer forearm length.
A square has 4 sides, and all sides have the same length.
If one side measures 12 inches, then the total length of all sides is 4 * 12 inches.
4 * 12 inches = 48 inches
All edges combined are a total of 48 inches.
He only has 36 inches of ribbon, so he does not have enough ribbon.
Answer: x = 9/4, y = 7/6
║<span>2x + 3y = 8
</span>║<span>4x - 6y = 2
</span>║4x + 6y = 16
║4x - 6y = 2
Add both equations together:
8x = 18
x = 9/4
Sub x = 9/4 into 2x + 3y = 8
2(9/4) + 3y = 8
9/2 + 3y = 8
3y = 7/2
y = 7/6
35 has 4 divisors, hence two factor pairs: 1*35 and 5*7. Each corresponds to a set of perfect squares that differ by 35
One pair is ((35±1)/2)^2 = {17^2, 18^2} = {289, 324}
The other is ((7±5)/2)^2 = {1^2, 6^2} = {1, 36}
