1.Ahmad has just received the results of three assignments that he completed last week. His marks were 34 out of 40 on his science fair project,64 out of 80 on
his geography presentation, and 21 out of 25 on his French oral dictation.
a)Calculate each of Ahmad's marks as a percent. b) To summarize his results,
Ahmad decides to calculate two average percentages: First, he calculated the
mean of the three percents in part a). Second, he calculated the percent of total
marks awarded out of total marks available for all three scores. Explain whether
these two percents should be the same. If not, which value should be higher.
Then calculate both values and compare."

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
