Answer:

She bought 15 napkins

Step-by-step explanation:

First find the price before coupon

1.5 * n where n is the number of napkins

Then subtract the coupon

1.5n - 20

This is the price she paid before tax

1.5n -20 = 2.5

Solving for n

Add 20 to each side

1.5n -20+20 = 2.5+20

1.5 n= 22.50

Divide each side by 1.5

1.5n/1.5 = 22.5/1.5

n =15

She bought 15 napkins

How many times smaller is 2 × 10^-10 than 4 × 10^-5

natta225 [31]

Answer:

200,000

Step-by-step explanation:

To find how many times smaller is smaller number than greater number, divide greater number by smaller number.

Greater number $=4\times 10^{-5}$

Smaller number $=2\times 10^{-10}$

Then

$\dfrac{\text{Greater number}}{\text{Smaller number}}\\ \\=\dfrac{4\times 10^{-5}}{2\times 10^{-10}}\\ \\=\dfrac{4}{2}\times \dfrac{10^{-5}}{10^{-10}}\\ \\=2\times \dfrac{1}{10^{-5}}\\ \\=2\times 10^5\\ \\=2\times 100,000\\ \\=200,000$

Therefore, half of 1/4 is 1/8. 1/4 means 0.25 if you devide it by 2 you will get 0.125 so 1/8 is half of 1/4.
