Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given a situation that
If an increase in one variable causes a decrease in another variable,
Then, there is inverse relationship.
When one variable is increased whereas other variable falls.
There will be inverse relationship.
Since inverse relation has negative relation.
Then, there is a negative relationship.
Hence, Option 'A' is correct.
Answer: width = 10 ft
Step-by-step explanation:
Area = length × width
Let l be length and w be width
l = w + 4 ........equation (1)
From above formula
140 = l × w. ........equation (2)
Substitute equation (1) into equation (2)
140 = (w+4) × w
w^2 + 4w= 140
w^2 + 4w - 140= 0
By factorization method
(w+14)(w-10)= 0
w=-14 or w= 10
So now width is 10 ft
From equation(1)
l=w+4
l= 10+4
l= 14 ft
Width = 10 ft and length = 14 ft
Answer:
b
Step-by-step explanation:
$25 per day
it's "b" because as days increase the cost of dollars gets added by $25 per day.

Answer:
z=4
Step-by-step explanation:
6+4=10
In order to find out the answer , you just need to count :
Let's say that mary's collection is symbolized by x
2/3 x = 4h
x = 3/2 . 4h
x = 6h
The storybooks they have in total would be : 6h + 4h = 10 h
hope this helps
