Answer:
You can do this two ways
1. Divide 170 into 4 parts and multiply by 3.
170/4=42.5
42.5 x 3 = 127.5 so 127.5 is the answer
2. 3/4=0.75
170 x 0.75 = 127.5
or 170/1 x 3/4 = 510/4 = 127 1/2
127 1/2 = 127.5 because 1 divided by 2 is 0.5__127 + 0.5 = 127.5
Hope this helps
Step-by-step explanation:
For distance in 1 minute, divide the distance for 6 minutes by 6 minutes:
7.5 km / 6 minutes = 1.25 km per minute.
For 100 minutes, multiply distance per minute by total minutes:
1.25 km per minute x 100 minutes = 125 km
5/6, 7/9, 3/5 make all have a common denominator of the LCM, 90 in this case:
(5/6)(15/15), (7/9)(10/10), (3/5)(18/18)
75/90, 70/90, 54/90
So now it should be clear which fraction are greater than others...
3/5, 7/9, 5/6 (from least to greatest)
Answer:x^2=2^2+4^2. x=4.47
Step-by-step explanation:
Opposite=m=2
Adjacent=n=4
Hypotenuse=x
x^2=m^2+n^2
x^2=2^2+4^2
x^2=4+16
x^2=20
x=√20
x=4.47
