Kate's bill for this month for one bulb will be $1.8225
Further explanation:
Given
Old Bill for one bulb use = $7.29
Percentage of reduction in bill = 75%
To find the new bill, we have to find the amount of saving that Kate will get by using the energy saver and then the amount will be subtracted from the previous bill of $7.29
So, the new bill will be:
Hence the bill this month will be $1.8225

Answer:
12,200 ft²
Step-by-step explanation:
The area of the lawn = the area of the trapezium - the area of the square
Note that area of a trapezium is h*(a+b)*(1/2), where h is the perpendicular height, and a and b are the top and bottom.
Note that the area of a square is l*w, where l is length and w is width.
Therefore, the area of the lawn = [h*(a+b)*(1/2)] + [l*w]
= [80*(100+140)*(1/2)]+[50*52]
= 9600+2600
=12200
You are adding 1 to the numerator, which means that the next numerator in the sequence is going to be 5. You are multiplying the denominator by 3, so it means that the next denominator in the sequence is going to be 162.
The answer is 5/162.
Answer:
25.
Step-by-step explanation:
We can write the expression as 10x + 2.5x where x is the tens digit.
So reversed we have 25x + x.
- and 25x + x - (10x + 2.5x) = 27
22.5x - 9x = 27
13.5x = 27
x = 2 and 2.5x = 5.
So the number is 25.
