Answer:
40.4
Step-by-step explanation:
Well...you see, 60% of $97 is equal to 58.2. you can get this by multiplying 97 by 0.60.
so subtract 97 by 58.2 and you will get 38.8, now you will add the tax which is and extra add-on to the prices full value
and it's a 4% tax so you will add for percent to 38.8,
basically multiply 38.8 times 0.04 and you will get 1.6 which you will have to add the your amount to get 40.4.
Answer:
3,4,5
Step-by-step explanation:
Here, we want to select the set that could work and the sides of a right angled triangle
the correct answer is 3,4,5
These set are called a Pythagorean triple
This is because adding the square of the two smaller number will give the square of the largest number
What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set
A = P + I
2a = a + PTR/100
2a = a + 5aT/100
2a = a(1+T/20)
2=1+T/20
T=20 yrs
