Answer:
1) 5% of 90m= 4.5m
2)25% of 88kg = 22kg
3) 75% of 264= 198
Step-by-step explanation:
1) 90m = 100% (divide by 10)
9 = 10% (divide by 2)
4.5 = 5%
2) 88kg = 100% (keep on dividing by 2)
44kg = 50%
22kg=25%
3) 264 = 100%
132 = 50%
66 = 25% (add)
198=75%
Answer:
The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.

Answer:
$ 22.22
Step-by-step explanation:
Let
P = amount to save per week
B = expected accurate at 16 years = $5000
r = APR = 3.9% = 0.039
n = numbers of week in a year = 52weeks
t = 16 - 12 = 4 years terms of savings.
Using,
P = (B * r/n)/{(1 + (r/n))^(nt) -1}
P = (5000 * 0.039/52)/{(1 + (0.039/52))^(52 * 4) -1}
P = $22.22
Answer:
D. 0.65
Step-by-step explanation:
0.05 x 5=0.25
0.01 x 5=0.05
0.07 x 5=0.35
0.25+0.05+0.35=0.65
they all must pay 0.65 each
