400/12 = # of dozen needed
.89 * # of dozen needed
400/12=33.33 need 34 dozen
.89*34=$30.26
So this is a special triangle. The 30-60-90 triangle rule states that if the short leg is y, then the hypotenuse is 2y and the long leg is y√3.
In this case, the short leg is 5√3 since that times √3 makes 15.
Now with the hypotenuse, just multiply 5√3 with 2, and your answer should be 10√3, or C.
The solution would be like
this for this specific problem:
Given: 40
km/h
2 km
t = d / v
t = 2 km / 40 km/h
t = 0.05 h * 60 minutes = 3 minutes
<span>At
this rate, it would take 3 minutes for the red kangaroo to jump 2 km.</span>
