Answer:
length = 30 cm
Breadth = 10 cm
Step-by-step explanation:
Length = x cm
Breadth = (1/3)x
Perimeter = 80 cm
2(length + breadth) = 80
2* (x + (1/3)x) = 80
x = 30cm
length = 30 cm
breadth = 
cm
30 is 20% of 150
Working out percentage problems of the form "30 is 20 percent of what number?"
We have, 20% × x = 30
or,
20/100 × x = 30
Multiplying both sides by 100 and dividing both sides by 20,
we have x = 30 × 100/20
x = 150
If you are using a calculator, simply enter 30×100÷20, which will give you the answer.
Hello, all we need to do in this case to subtract the amount of money Bob paid for the suit from the amount of money the suit regularly costs. So:
375,95 - 268,35 = 107,6
Bob saves 107,6$.
97% because that is the average of the three test scores.
