Answers

Answer: Board is 357 cm long.

Step-by-step explanation:

Since we have given that

Suzanna wants to measure a board but she doesn't have a ruler to measure with,So she has several copies of a book that she knows is 17 cm tall where She lays the books end to end to find the length of board which is the same  length as  21 books.

So,

Number of books = 21

Length of board of each book = 17 cm

According to question, we need to find the length of board for 21 books:

Length of board is given by

21* 17\n\n=357\ cm

Hence, Board is 357 cm long.
Answer=357centimeters

21*17=357cm

50% of what number is 90?

Answers

The answer would be 180 because if 90 is 50% and that's half of 100 then the other 50% would also be 90 and added together that is 180
to get to 100 percent you have to double the number so when you double 90 you get 180

90+90=180.

a sailfish can swim up to 1 mile per hour less than one fifth the top speed of a peregrine falcon. Find the top speed that a sailfish can swim?

Answers

top speed of a peregrine falcon is 240 miles per hour

 240 x 1/5 = 48

48-1 = 47

 sailfish can swim 47 miles per hour

Answer: The top speed that a sailfish can swim at ((x)/(5)-1)\ mph

Step-by-step explanation:

Since we have given that

Top speed of a peregrine falcon be 'x'.

One fifth the top speed of a peregrine falcon would be

(1)/(5)x

1 mile per hour less than the above is expressed as

(1)/(5)x-1

According to question, the top speed that a sailfish can swim would be

(1)/(5)x-1

Hence, the top speed that a sailfish can swim at ((x)/(5)-1)\ mph
