The teacher probably wants you to multiply cause area refers to that
To find your answer you would divide 21 by 3 which would be 7, once you've got 7 you would multiply it by 9 which would give you the amount of old houses that there is which would be 63.
Using the law os cosines formula b^2 = a^2 + c^2 - 2*a*c*cos(B)
a = 17, b = 8, c = 16
8^2 = 17^2 + 16^2 - 2*17*16* cos(B)
64 = 289 + 256 - 544 * cos(B)
544*cos(B) = 289 + 256 - 64
544 * cos(B) = 481
cos (B) = 481/544
B = arccos(481/544)
B = 27.8 degrees
10 kilograms is equal to 10,000 grams
Step-by-step explanation:
1 kilogram = 1000 grams
To know how many grams does 10 kilograms consists is we need to multiply with 1000 to 10 then we can obtain 10 kilograms in grams.
10 kilograms = 10 × 1000
10 kilograms = 10,000 grams.
