Answer:
380
Step-by-step explanation:
8 is 40% of 20
so just do
950x.40 which equals 380
Answer:
p1= 95, p2 = 180
Step-by-step explanation:
We have population : 50 given that population grows by 90% per year
So, After one year: new population (p1) will be
p1 = 50 + 50*0.9 = 50 + 45 = 95
Now, After two years: new population (p2) will be
p2 = 95 + 95*0.9 = 95 + 85.5 (approximately = 86) = 95 + 86 = 180
Therefore,
p1 = 95, and p2 = 180.
Divide the number of questions she got correct by the total number of questions on the test them multiply the decimal answer by 100 to get the percent.
42/60 = 0.7
0.7 x 100 = 70%
