Answer:
w = (p - 2l) / 2
Step-by-step explanation:
Step 1: Distribute
P = 2l + 2w
Step 2: Move 2l over
P - 2l = 2w
Step 3: Divide everything by 2
(p - 2l)/2 = w
And you have your perimeter equation in the term of <em>w.</em>
Answer:
1.875 %
Step-by-step explanation:
Divide the sample size by the population then multiply by 100:
percent = (75 ÷ 4000) x 100 = 1.875 %
Just do the base by height divided by pie
Answer:
therefore x = 600 mph
therefore the speed of the other plane y = x - 110 = 600 - 110 = 490 mph
Step-by-step explanation:
i) Two planes are 2725 miles apart and are travelling towards each other.
ii) One plane is travelling 110 mph faster than the other plane.
iii) the planes pass each other in 2.5 hours
iv) let the speed of one plane be x mph
v) let the speed of another plane be y mph
vi) therefore x - y = 110 mph
vii) and also x + y = 2725/2.5 = 1090
viii) adding the equation in vi) to the equation in vii) we get 2x = 1200
therefore x = 600 mph
ix) therefore the speed of the other plane y = x - 110 = 600 - 110 = 490 mph
If ur trying to get x you would just divide 6/7 which is x=.85 hope this helps if not let me know plz and have a nice nite happy Halloween
