in a survey of teens, 21% said their friends like to read and talk about books. About how many teens out of 1,095 would say their friends read and talk about books?

Answers

Answer:

About 230 teens would say that their friends read and talk about books.

Step-by-step explanation:

From the survey, 21% of teens like to read and talk about books.

                21% = (21)/(100)

Thus, from 1095 teens, 21% of them would say their friends read and talk about books.

       21% of 1095 = (21)/(100) × 1095

                           = (22995)/(100)

                           = 229.95

     Therefore, about 230 teens from 1095 would say that their friends read and talk about books.
21÷100=0.21 0.21×1095=230 friends estimeted from 229.95

Find the area of a parallelogram with base (b) = 140 cm and height (h) = 9.7 cm. A. 1358 cm² B. 1386 cm² C. 1368 cm² D. 1308 cm²

Answers

Answer:

A

Step-by-step explanation:

the area (A) of a parallelogram is calculated as

A = base × height

given base = 140 cm and height = 9.7 cm , then

A = 140 × 9.7 = 1358 cm²
