Answer:
Option A - 7.3.
Step-by-step explanation:
Given : Number 7.323.
To find : Which number is 7.323 rounded to the nearest tenth?
Solution :
Rounded to the nearest tenth rule :
1) If the hundredths place of a decimal is greater than or equal to five, then tenth place number is added by 1.
2) If the hundredths place of a decimal is less than five, then tenth place number does not change.
In the number 7.323
The Hundredth number is 2 < 5 so tenth number does not change.
7.323 rounded to the nearest tenth is 7.3.
Therefore, Option A is correct.
After subtracting 3 from 7, and dividing 4 by 2, you should end up with x=2.
The number of ants in his farm after 12 weeks is 218.
Step-by-step explanation:
Step 1:
It is given that there are 15 ants initially and the ant population increases by 25% each week.
This is an exponential rate of increase that can be modeled by the following equation:
Number of ants after n weeks = Initial number of ants * 
Step 2:
Rate of increase = 25% = 25 / 100 = 0.25
Number of weeks = 12
Number of ants after 12 weeks = 15* 
= 218.27 (rounded off to 218)
Step 3:
Answer:
The number of ants in his farm after 12 weeks is 218.
Answer:
a. True.
Step-by-step explanation:
y = kx
y = 2 when x = 8 gives:
2 = 8 * k
k = 2/8 = 1/4.
