Answer:
1. 7
2. 15
3. 181
Step-by-step explanation:
Just make sure that you make your denominator a whole number
1. 9.8/1.4....,you multiply by 10...which only removes the comma but it keeps the structure of the question
Always remember that what you do to the denominator...you also do to the numerator
: 9.8/1.4 × 10/10 = 98/14 = 7
2. 40.5/2.7....,you multiply by 10
: 40.5/2.7 × 10/10 = 405/27 = 15
3. 3.62/0.02...., you multiply by 100
: 3.62/0.02 × 100/100 = 362/2 = 181
Answer:
196
Step-by-step explanation:
To solve this, I broke it down into two parts.
A. Number of routes going to Town C
4 x 3 + 2 = 14
B. Number of routes going back to Town A
3 x 4 + 2 = 14
From here, it is easy to see what to do. Since there are 14 routes going to Town C and 14 routes going back, the answer is 14 x 14 = 196.
Step-by-step explanation:
Rate of growth equals 420/100 = 4.2 times per hour
So after t=three hours,
size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,
round to nearest unit 7409 bacteria after three hours (after initial size of 100).
