The mass of a hummingbird is 4,000 milligrams. Use a
proportion to convert 4,000
milligrams to grams

PLEASE HEL

4 grams

Step-by-step explanation:

There are 1000 milligrams in a gram, so the proportion is 1g/1000mg=xg/4000mg

when you cross multiply, you get 1000xg=4000mg/ divide both sides by 1000 and you get xg=4, meaning x=4 grams

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
