Step-by-step explanation:
so sin(π/4) is √2/2 squaring this gets your first answer
second answer is just plug and chug in a calculator

Answer:
Clara will reach more people in 40 phone calls.
Step-by-step explanation:
If Both of them had 40 phone calls you would divide 40 phone calls to how much they actually had. In this case for Clara it's 40 divided by 10 which is 4, And then you have to multiply 4x4 which is 16. For Toby He had to divide 40 by 8 which is 5, and then multiply 3x5 which is 15. Therefore Clara had reached more phone calls then Toby.
Independent variables must be the amount of cans you buy of cat food. The dependent variable, well that must be the cost. Depending on how many cans you buy, the cost changes! :)
Multiply first example by 3 and subtract by second example, you will get the following:
3*(5x + 2y) = 3*22 => 3*5x + 3*2y = 66 => 15x + 6y = 66
now subtraction:
(15x + 6y) - (-2x + 6y) = 66 - 3
15x + 6y + 2x - 6y = 63
15x + 2x + 6y - 6y = 63
17x = 63
x = 63/17 ≈ 3.705..... and as it says to round to the nearest tenth our answer would be: x = 3.7
