Let's not think about the problem, let's think about the fractions and dividing. We're are trying to find how many sets of 3/44 are in 3 3/4. We need to divide. Using keep change and flip, we can divide successfully.
Let's make sure the first fraction is improper.
15/4÷3/44=?
Keep, Change, and Flip.
15/4×44/3
660/12
Let's simplify.
55.
So Nicole can play 55 rounds.
Answer:
W = 69.5 L = 109.5
Step-by-step explanation:
L = 3W-99
Perimeter = 2L + 2W
358 = 2(3W-99) + 2W
358 = 6W-198 + 2W
358 = 8W-198
556 = 8W
69.5 = W
- 358 = 2L+2W
- 358 = 2L + 2(69.5)
- 358 = 2L + 139
- 219 = 2L
- L = 109.5
Answer:
8 = f (13-2)
8=13f-2f
8=11f
8 / 11 = 11f / 11
8/11=f
f=8/11
Step-by-step explanation:
We write the generic exponential equation:
y = A (b) ^ t
Where,
A: initial population
B: growth rate
t: time in hours.
Substituting values we have:
y = 5 (2) ^ ((1 / 1.5) * t)
For t = 9 hours we have:
y = 5 (2) ^ ((1 / 1.5) * 9)
y = 320 million
For t = 24 hours (one day) we have:
y = 5 (2) ^ ((1 / 1.5) * 24)
y = 327680 million
For t = 2 hours we have:
y = 5 (2) ^ ((1 / 1.5) * 2)
y = 12.5992105 million
Answer:
a) t hours?
y = 5 (2) ^ ((1 / 1.5) * t)
b) 9 hours?
y = 320 million
c) 1 day?
y = 327680 million
d) 2 hours?
y = 12.5992105 million
(3^0-(3^2)^3)/9^3
3^0=1
3^2=(3*3)=9->9^3=(9*9*9)=729
1-729=-728
9^3=(9*9*9)=729
-728/729
