Using the information given, calculate a grade to the nearest whole percent. the "rise" is 525 feet. if the scale on the map showed the "run" on the west side is 800 feet. the grade on the west side would be

the rise on the east side will still be 525 feet.

but, the scale shows the run is 1300 feet.

the grade on the east side would be

Anne found the 10th term of the following sequence. her steps are shown below. 3, 7, 11, 15, … 1. common difference = 4, a1 = 3 2. an = 3 + (n - 1)4 3. an = 3 + 4n - 4 4. an = 4n - 1 5. a10 = 4(10) – 1 6. a10 = 39 analyze anne’s work. is she correct? if not, what was her mistake? yes, she is correct. no, she needed to find the common ratio because it is a geometric sequence. no, she substituted the wrong values into the rule to find the equation that represented the sequence. no, she solved for the 10th term incorrectly.
