Across x = 4 -> (8,0)
Across y = -3 -> (8,-6)
Answer:
Step-by-step explanation:
<u>Given:</u>
- Borrowed amount P = Rs 100000
- Time t = 3 years
- Number of compounds n = 3
- Interest I = Rs 33100
- Rate r = ?
<u>Use formula:</u>
<u>Substitute values and solve for r:</u>
- 33100 = 100000(1 + r)³ - 100000
- 133100 = 100000(1 + r)³
- (1 + r)³ = 133100/100000
- (1 + r)³ = 1.331
- 1 + r = ∛1.331
- 1 + r = 1.1
- r = 0.1 or 10%
We know that in 2 ½ hours (2.5 hours), we can create 3
cakes hence:
C = k t
where C is number of cakes, k is constant, and t is time
k = 3 cakes / (2.5 hours)
k = 1.2
C = 1.2 t
So for t = 7 ½ hours = 7.5 hours
C = 1.2 (7.5)
<span>C = 9 cakes in 7 ½ hours</span>
