A worker bee has a mass of \,1\cdot{ 10^{-4}}1⋅10 −4 1, dot, 10, start superscript, minus, 4, end superscript \text{kg}kgstart text, k, g, end text. There are 4\cdot{ 10^4}4⋅10 4 4, dot, 10, start superscript, 4, end superscript worker bees living in one hive. What is the mass of all the worker bees in the hive together? Write your answer in scientific notation.

the correct answer is 5 6 and 7

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
