3sqrt(2)
You can either use Pythagorean theorem or special triangle proportions to find the side that is parallel to z. Since in a 45-45-90 degree triangle, the hypotenuse is the leg times the square root of 2, and the hypotenuse is 3, we know that the leg is 3/sqrt(2) which is equal to 3 sqrt(2) / 2. Since z is twice this length, we know that z is equal to 2 x 3sqrt(2)/2 = 3sqrt(2)
get a common denominator of 18
5/6 * 3/3 +4/9 * 2/2 - -2*18/18
15/18 +8/18 + 36/18
23/18 + 36/18
59/18
change to a mixed number
18 goes into 59 3 times with 5 left over
3 and 5 /18
1. 3h+11
2. -2r
3. g-4
4. 5f+4
5. 15z
top left: speed = 2.7 miles per hour = 2.7 MPH
top right: speed = 0 miles per hour = 0 MPH
bottom left: speed = 4 miles per hour = 4 mi/h
bottom right: speed = 2 miles per hour = 2 mi/h
and so, the fastest is bottom left. And pay attention in class! i'm in highschool and Iearned this in 6th grade!
Step-by-step explanation:
key: speed= distance/time
distance= speedxtime
time=distance/speed
top left: 8/3= 2.66667 MPH= 2.7 MPH
top right: 0/8= 0 MPH= 0 MPH
bottom left: 8/2= 4 MPH= 4 MPH
bottom right: 8/4= 2 MPH= 2 MPH
