Distance:time=25:13.7
ratio and propriton
4min=60sec*4=240sec
25/13.7=?/240
times both sides by 240*13.7
25*240=13.7?
6000=13.7?
divide both sides by 13.7
437.9562=?
about 438 meters
Step-by-step explanation:
Given
mZEFH = (5x + 1)'
mZHFG = 62°
mZEFG = (18x + 11)',
The addition property of the angle is true
mZEFG = mZEFH + mZHFG
(18x + 11) = (5x + 1)'+ 62
18x+11 = 5x + 63
collect like terms
18x - 5x = 63-11
13x = 52
divide both sides by 13
13x/13 = 52/13
x = 4
Since angle mZEFH = (5x + 1)' and x = 4, we will substitute x = 4 into the function;
mZEFH = 5(4) + 1
mZEFH = 20 + 1
mZEFH = 21°
Similarly for mZEFG = (18x + 11)'
mZEFG = 18(4) + 11
mZEFG =72+11
mZEFG = 83°
Answer:
2.44 miles
Step-by-step explanation:
Give the following :
Average miles to school = 12 miles per hour
Average Miles from school = 15 miles per hour
Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667
Recall:
Speed = distance / Time
Time = distance / speed
Let distance = d
For the scenario described :
d/12 + d/15 = 0.3667
(5d + 4d) / 60 = 0.3667
5d + 4d = 22
9d = 22
d = 22/9
d = 2.44 miles
So, 3 boxes x 10 markers=
30 markers/ 5=
6 markers each person will get.
This answer is pretty simple.
Since there are 2 yards of ribbon, and you need to make ____ number of pieces with each 9 long
To do this you divide.
2 divided by 9
The answer is 11
