Step-by-step explanation:
Answer: 60 different numbers can be formed
Step-by-step explanation:
Note that we have 5 different digits, and we must select 3 of them. They should not be repeated
The order of selection is important in this case, because the number 532 is not the same as the number 235.
So we have a permutations problem, where we have a set of n elements and we want to choose r from them.
Then we define the permutacion as:

In this case note that n=5 because there are 5 elements in the set.
r = 3 because we combine the elements to form three-digit numbers
Then:





Answer:
Cost without vat is 1,368.5
Step-by-step explanation:
Here, we want to know the cost of the iron without the vat.
From the question , we can see that 15% VAT brought the cost to 1610.
This means that the original cost without vat is 100% -15% = 85% of the total
Thus;
85/100 * 1610 is the cost without vat
And that is;
136850/100 = 1,368.5
Answer: 180 degrees
Step-by-step explanation:
The measure of the arc of a semicircle is 180 degrees.
A=30
Multiply base times height and then divide by 1/2
(3 3/4)(4)=15
15/(1/2) = 30
