Answer:
56
Step-by-step explanation:
she ate 25% so she is left with 75%
you want to find that 25% so you do 75÷25=3
42÷3=14
25×4=100
14×4=56
she had 56 pretzels
Answer:
0.9%
Step-by-step explanation:
Given that:
A nest of ant is represented by the exponential growth function :
P(w)=24,000(1.063)^w
Where w = number of weeks
Recall :
Growth function is generally represented as :
P(t) = A(1 + r)^t
Where ; A is the initial population figure; r = growth rate and t = time
Hence, the growth rate per week of the function given is :
(1 + r) = 1.063
r = 1.063 - 1
r = 0.063
Number of days in a week = 7
Hence, growth rate per day = r /7
0.063 / 7
= 0.009
(0.009 * 100%) = 0.9%
Answer:
please attach the picture of figure
Step-by-step explanation:
Six point eight four.
(Note, you don't say, "Six point eighty-four" As it doesn't sound correct.
Cheers.
