In 1990 the postal rate was 25 cents for the first ounce and 20 cents for each additional ounce part of an ounce. What did it cost to mail a package that weighed 6.8 ounces? Not going to show answer options bc I don’t want someone to just put anything :)

DONT PUT LINKS (I’m not going to press it so don’t waist your time lol)

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

step-by-step explanation: i dont

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
