Mike can cut a 40 foot by 20 foot yard with a push mower in 25 minutes. At this rate, how many more minutes would it take him to

Area of the yard is  40 .20  =  800sq ft
time taken = 25 mins
time taken to mow 1sq ft  =      25/800 mins
time taken to mow  40 .30 =1200sq ft  =      ( 25 .1200)/800 =    371/2 mins
thus the extra time  taken will be      371/2-25 =    121/2 mins

A bus travels 90 km in 1.5 hours (with a constant speed). How far can it travel in 7.2 hours (with the same speed)?​
blondinia [14]

Answer:

distance=90km

time=1.5h

speed of the bus=distance /time

speed of the bus=90km/1.5h

speed of the bus=60km/h

therefore if 1.5h=60km/h

then 7.2h=(7.2x60)/1.5 =288km

PLEASE HELP! What is the area of triangle BCD in exact form? 35 points!
vampirchik [111]
This is a 30-60-90 triangle. The short leg is given to us as 5 

The long leg is equal to sqrt(3) times the short leg

long leg = sqrt(3)*(short leg)
long leg = sqrt(3)*5
long leg = 5*sqrt(3)

The base is 5. The height is 5*sqrt(3)
b = 5
h = 5*sqrt(3)

Use this to find the area
A = b*h/2
A = 5*5*sqrt(3)/2
A = 25*sqrt(3)/2
which is the exact area in terms of a radical

You can write it out as \frac{25\sqrt{3}}{2}
