Step-by-step explanation:
the area is
length × width
increasing the length by 30% means multiplying the original length by 1.3.
increasing the width by 10% means multiplying the original width by 1.1.
so, the new area is (by using the old length and width)
length × 1.3 × width × 1.1 = length × width × 1.3×1.1 =
= old area × 1.3 × 1.1 = old area × 1.43
so, the area increases by 43%.
Answer:
I need this question 2!
Step-by-step explanation: can someone please answer this.
Let us assume the number of cars parked after which John will start earning more than his fixed weekly salary = x
The fixed weekly salary of John = $300
The fee that John gets for parking each car = $5
Then we can get the equation as
5x = 300
x = 300/5
= 60
So from the above deduction we can see that John will earn the equal amount of his weekly pay after he parks 60 cars. Then it becomes obvious that parking car number 61, John will start earning more than what he gets as his fixed weekly salary. I hope you have understood the described method.

Subtract the blue caps:
25-11 = 14 caps are either white or green.
Let green = X
white = X +2
Green + white = 14:
x + x +2 = 14
Combine like terms:
2x +2 = 14
Subtract 2 from both sides:
2x = 12
Divide both sides by 2:
x = 6
There are 11 blue caps, 6 green caps and 8 white caps.
