its some t.v show I guess
Because it's decreasing, you use the formula (1-x/100)y with x the percentage decreased which is here 40, and y the number decreased which is here 90
So we get
(1-40/100) * 90
(100/100 - 40/100) * 90
60/100 * 90
5400/100
54
So 90 decreased by 40% is 54
Hope this Helps :)
Answer: 
Step-by-step explanation:
Given
The theoretical probability of choosing an event A is 
The sum of the probability of occuring and non-occuring of an event is always equal to 1.
So, the probability of non choosing Event A is
One pound of the item will cost 4.74 bill
Step-by-step explanation:
In this problem, we are told that Delia bought 4.5 pounds of fruit
and paid with a toa total bill of 20+5= 25 bill
and also she received a change of 3.67
this means that the item she bought cost 25-3.67= 21.33bill
now if 4.5 pounds of items cost 21.33 bill
then 1 pound will cost Xbill
cross multiply and solve for Xbill
X= 21.33/4.5
X= 4.74 bill
One pound of the item will cost 4.74 bill
Answer:
P = 160/A
Step-by-step explanation:
For P to vary inversely with A, we must have P be proportional to the reciprocal of A. The constant of proportionality is given.
<h3>Inversely proportional</h3>
Two quantities are directly proportional if there is a constant of proportionality (k) that multiplies one of them to give the value of the other:
y = kx
They are inversely proportional if the inverse of one of them can be multiplied by a constant of proportionality to give the value of the other:
y = k(1/x) = k/x
In this problem, the variables P and A are said to be inversely proportional. That means the equation that relates them will be of the form ...
P = k/A
You are given such a form with k=160, which is an appropriate value for the relation given by the problem. All you need to do is fill in the variable:
P = 160/A
