The amount of milk containing 6% butterfat and 1% butterfat are 260 gallons and 65 gallons respectively.

<u><em>Explanation</em></u>

Suppose, the amount of milk containing 6% butterfat is x gallons

As the amount of mixture of milk should be 325 gallons, so the amount of milk containing 1% butterfat will be: (325-x) gallons

Given that, the mixture of milk is containing 5% butterfat. So, the equation will be....

0.06x+0.01(325-x)=0.05*325\\ \\ 0.06x+3.25-0.01x=16.25\\ \\ 0.05x= 13\\ \\ x= \frac{13}{0.05}=260

So, the amount of milk containing 6% butterfat is 260 gallons and the amount of milk containing 1% butterfat is (325-260) gallons = 65 gallons.

A radio controlled car travels 27 km and 28.5 minutes what is the speed of the car​
olya-2409 [2.1K]

Answer:

56.842 km/hr

0.947 km / min

15.789 m/s

Step-by-step explanation:

speed = distance / time

let's assume your teacher wants it in km/ hr

28.5 minutes = ? hours

60 minutes = 1 hour

we can multiply both sides of 60 minutes = 1 hour by 28.5/60 to get 28.5 minutes = 28.5/60 hours

distance = 27 km

27 km / (28.5/60) hours = 56.842 km/hr

in km / minute

27 km / 28.5 minutes = 0.947 km / min

in meters/second:

1 minute = 60 seconds

28.5 minutes = ? seconds

we can multiply both sides of the first equation by 28.5 to get

28.5 minutes = 1710 seconds

27 km = ? meters

1 km = 1000 meters

we can multiply both sides of the second equation by 27 to get

27km = 27000 meters

27000 meters / 1710 seconds = 15.789 m/s
