The ratio of boys to girls in a class is 5:7 there are 36 students in the class how many more girls than boys are there

There are 6 more girls than boys in a class of 36 with a boy ratio of 5:7

Step-by-step explanation:

5:7  where 5 + 7 = 12

therefore 12 x 3 = 36

3 x 5 = 15 boys

3 x 7 = 21 girls

21-15 = 6 more girls.

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:
