Suppose you measured the diameter of a tree trunk to be 5 cm. the actual diameter can vary by at most 0.4 cm, due to the error in measuring a non-flat surface. write an absolute value inequality for the range of acceptable diameters and solve the inequality.
a. |d − 5| ≤ 0.4; 4.6 ≤ d ≤ 5.4
b. |d + 5| ≤ 0.4; −5.4 ≤ d ≤ −4.6
c. |d + 0.4| ≤ 5; −5.4 ≤ d ≤ 4.6
d. |d − 0.4| ≤ 5; −4.6 ≤ d ≤ 5.4

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
