Answer:
0.95
Step-by-step explanation:
19/20 as a decimal is 0.95
3π/4 angle is in the second quadrant, so cos (3π/4) is going to be negative.
Reference angle of 3π/4 is (π - 3π/4) = π/4
cos(π/4) = √2/2
cos (3π/4) = - √2/2
Answer is C.
Answer:
113.
Step-by-step explanation:
119 is divisible by 7.
117 is divisible by 3.
I think it's 113.
If you use your calculator to divide 113 by odd numbers up to 57 you can check if it is prime. You stop at 57 because 57*2 = 114. You need not divide by any number ending in 5 because 113 ends in 3.
I have done this and can't find a quotient that is a whole number so it must be prime (unless I've made a mistake!).

Kelly walks 4/5 of a mile each day.
After 3 days, Kelly walks a distance: D = 3 x 4/5 = 12/5 = 2.4 miles
Hope this helps!
