We can write one fifth as
7 times of w , we can write as = 7w
Now we have to subtract one fifth from seven times of w.
So we can write it in algebraic expression as
Answer:
Proportional
Step-by-step explanation:
If she burns 15 per minute, the she will burn 30 in 2 min and 45 in 3 min, etc. Therefore it is proportional.
Answer:
sqrt(1 - 36/49) = +root(13)/7
Step-by-step explanation:
sin^2t + cos^2t is identical to 1 for all t.
(6/7)^2 + cos^2t = 1
1 - 36/49 = cos^2t
hence plus/miuns sqrt(1 - 36/49) = cos(t)
since t is acute, the answer must be positive.
You can divide 950 by 19 to get the speed in ft/min:
950/19 = 50 ft/min
Hope this helps! :)
