Answer:
6 ft longer (total length of 15ft)
Step-by-step explanation:
the initial dimensions are:
length: 
width: 
the area area of the garden is given by:
so the original area is:
Since we need the area to be 
, and we can only change the length, the width will still be 8ft.
We substitute the value of the new area and the width to the equation for the area:
and we clear for the new length:
The length of the garden for the area to be , must be 15ft.
This means that if originally the length was 9 ft, now it has to be 6 ft longer.

Answer:
The answer is 43% or 0.43
Step-by-step explanation:
Given:
Probability that person selected aged 35years or older is a smoker = 17.5%
Probability that person selected aged 35years or older is a female comma =25.5%
Solution:
a) Probability (35yrs or older is a smoker) + probability (35years or older is a female comma)
= 17.5% + 25.5%
= 43% 0r 0.43
b) No, it would not be unusual because it is by chance, it may and it may not.
Answer:
A
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
= 
Multiply both sides by 7, thus
AC = 7sin40° → A
Answer and Explanation:
The problem provides the following information:
