Use a calculator to evaluate sec 85 degrees

1 answer:

3 0

OK. I used my calculator to evaluate sec(85 degrees).

My calculator doesn't have a "sec" button on it.
But I remembered that

sec of an angle = 1 / (cosine of the same angle) .

So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).

Chris is a college student who can work a maximum of 40 hours per week. He needs to make at least $900 in order to cover his exp

IgorC [24]

Equation 1: x + y = 40 ; therefore y = 40 - x
Equation 2: 25x + 15y = 900
Find x first:

25x + 15 (40 - x) = 900
25x + 600 - 15x = 900
10x = 900 - 600
x = 300÷10
x = 30 hours Chris needs to spend for tutoring job

y = 40 - 30
y = 10 hours Chris needs to spend for referencing job

You spend 2 1/2 hours online. You spend 1/5 of that time writing a blog. How long do you spend writing your blog?

That would be 30 minutes since 2 1/2 hours equals 150 minutes, a fifth of 150 is 30.
