The liberia zoo had 30 giraffes in its exhibit. the zoo loaned 7 giraffes to a neighboring zoo. how many giraffes remained at the liberia zoo? which equation models the situation? how many giraffes remained at the liberia zoo?

The first one is 30-7=x and the second one is 23

Step-by-step explanation:

So 30-7=23 hope this helps :)

where r the answers

step-by-step explanation:

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:
