40 x 8 is 320, and there’s 31,536,000 seconds in a year so multiply both of those :)
The following expressions equivalent to c. None of the above
15% = 0.15
multiply the bill ( 42.00) by 0.15 for the amount of tip
42.00 * 0.15 = 6.30
the tip = $6.30
Answer:
cos(E)=0.8
Step-by-step explanation:
cos(E)=adjacent/hypotenuse
Using a common pythagorean triple, we can find that side GE is 30 (18^2+24^2=30^2)
Then we just get cos(E)=24/30, which is 0.8
