Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 ⅗ door. How many liters of paint are needed for 1 door?

1.25 litres

Step-by-step explanation:

Two litres of paint is sufficient to paint  1 ⅗  doors.

To find out the amount of paint needed to paint one door, you can use direct proportion:

2 litres           :              1 ⅗  door

x                                    1 door

Cross multiply to get:

1 ⅗ x = 2

x = 2 /  1 ⅗

x = 2 ÷ 8/5

x = 2 * 5/8

x = 1.25 litres

56

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
