Speed is the ditance traveled by a certain object given a certain time span. To solve this problem we need to divide the distance by the time given. Before that, the problem asked us to get the speed in terms of miles per minute and we are given a distance of 3 kilometer. We have to convert this to miles. 3km(0.6miles/km) = 1.8 miles. The speed is then 1.8/20 = 0.09mi/min.
Answer:
yo i only got number 4 for you but here it goes.......: 0.70x+18y-5
Step-by-step explanation:
(0.75x - 12y) + (-5 + 6y - 0.5x)
regroup to the variables : (0.70x-0.5x) + (12y+ 6y-5)
put it together: (0.70x)+(18y-5)
you cant add unlike terms so you remove the parenthesies and your done.
Answer:
<u>6.2 = Altitude</u>
Step-by-step explanation:
Hypotenuse = 8
Base = 5
Altitude = x
Hypotenuse² = Base² + Altitude²
8² = 5² + Altitude²
64 = 25 + Altitude²
64 - 25 = Altitude²
39 = Altitude²
√39 = Altitude
<u>6.2 = Altitude</u>
