A segment? ????? Not so sure about that one
I don't think that you can. Integers are either positive or negative real numbers without decimals, so there isn't anything to simplify.
Answer:
204/325
Step-by-step explanation:
You can work this a couple of ways. We expect you are probably expected to use trig identities.
cos(A) = √(1 -sin²(A)) = 24/25
sin(B) = √(1 -cos²(B)) = 12/13
cos(A -B) = cos(A)cos(B) +sin(A)sin(B) = (24/25)(5/13) +(7/25)(12/13)
= (24·5 +7·12)/325
cos(A -B) = 204/325

The other way to work this is using inverse trig functions. It is necessary to carry the full calculator precision if you want an exact answer.
cos(A -B) = cos(arcsin(7/25) -arccos(5/13)) = cos(16.2602° -67.3801°)
= cos(-51.1199°) ≈ 0.62769230 . . . . (last 6 digits repeating)
The denominators of 25 and 13 suggest that the desired fraction will have a denominator of 25·13 = 325, so we can multiply this value by 325 to see what we get.
325·cos(A-B) = 204
so, the exact value is ...
cos(A -B) = 204/325
Answer:
It takes 20 minutes for each dog
Step-by-step explanation:
she wants to spend an equal amount of time with each dog she has 145 minutes to play with all 7 dogs
It takes 145 minutes to play with 7 dogs
for 7 dogs it takes 145 minutes
To find the time taken for 1 dog , divide 145 by 7
It takes 20 minutes for each dog
So base on the question that is asked in the problem which state that to express the number 13001 kg as an integer, and base on my research, the said number is an integer and doesn't need to be converted. I hope you are satisfied with my answer and feel free to ask for more
