7 : x = 2 : 3
- divide 7 by 2.
7/2 = 3.5
- this is the scale factor.
- now multiply this by 3.
3 X 3.5 = 10.5
so, x = 10.5
Answer:
Part A) 
Part B) 
Step-by-step explanation:
Part A) What is the explicit rule for the number of residents
we know that
In this problem we have a exponential function of the form

where
a is the initial value
b is the base
r is the rate
(1+r)=b
so
Let
y ----> the number of residents
x is the time in years
we have
a=1,000 residents
r=1%=0.01
b=(1+0.01)=1.01
substitute

Part B) How many residents will there be in the town in Year 10?
For x=10 years
substitute in the equation


Answer:
x=13
Step-by-step explanation:
hehe calculator boy
Since they are consecutive, we can define the two unknowns with ease.
The left page (has a smaller value) can be defined as X, and the right page can be defined as X+1.
So,
X + (X+1) = 293
2x+1 = 293
2x = 292
x = 146
So, as we defined before, the smaller page number is equal to x. Therefore, the smaller page number is 146, and the larger page number is 147.
11.6 rounded to the nearest whole is 12 and 4.1 rounded to the nearest whole is 4 (rule is if the decimal [or number in general] is 4 or lower, the whole stays the same and if the number is 5 or higher, the whole goes up by one). 12+4=16
