Which integer is the smallest?

A: 0
B: 29
C: -30
D: -1

-30

Step-by-step explanation:

0 is greater the -30 and -1 but less then 29

29 is greater then 0, -30, and -1

-1 is less the 0 and 29 but greater then -30

-30 is less then 0, 29, and -1

from greatest to smallest

29, 0, -1, -30

-30 is the smallest integer

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

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
