so just like Ms. Sue said, you can you use a proportion. 1/20 would be the people owning at least one bird. So, 1/20 * 500 = 25. We get 25 people who were surveyed and owned at least one bird. Next time just post another question I guess :D

Math
darjeeling tea to the ratio of the entire blend is 5 (in the ratio it is given) / 9 (sum of both teas) = 5/9 so, 5/9 * 90 ounces = 50 ounces thus the answer is 50 ounces. sorry for being unclear

Math
50

Chemistry
Molar mass of Ar = 39.948 g/mol according to convertunits. com a mole is equal to 6.022 * 10^23 therefore, 5.8 * 10^24 / 6.022 * 10^23 * 39.948 is your weight.

Maths
Woops misread question. It would be 200/4 = 50cm^2

Maths
xy = 200 2x*2y = 4xy 4 * 200 = 800

math
4x^2=32 x^2 = 8 x = sqrt8 x = 2sqrt2 plug back in to get 2sqrt2 squared * 4 = 32 8 * 4 = 32 32 = 32 so correct

math
1/ (1/5+1/7) = 1/ (12/35) = 35/12 hours

math
sir, we are not given how many shirts 5 seamstresses can make in 3 days so therefore it is impossible to determine the problem.

math
45 < 3m 15<m so any number more than 15 will do for the smallest integer, then 16....
