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
A) Volume of a cube is found by multiplying its side by itself twice.
V = a³
V = 4³ = 4 * 4 * 4
V = 64 ft³
b) 1 cubic foot = 7.48 gallons of water.
total gallons of water = 64 ft³ x 7.48 gallons = 478.72 or 479 gallons rounded up to the nearest gallon.

Step-by-step explanation:
1, 2, 3, 5, and 7 are all functions. 4, 6, 8, and 9 are not functions.
Answer and explanation;
= 1/15 is the answer get when 36 is divided by 540 .
We can use the partial quotients to divide 540 by 36 then we get the reciprocal of the answer;
540 ÷ 36
We can take 360 ÷ 36 = 10
Then the remainder is ; 540 -360 = 180
But ; 180 ÷36 = 5
Then we get the sum of the quotients which is 10 +5 = 15
Thus; 540 ÷ 36 = 15
However; the question was 36 ÷ 540 , so we get the reciprocal of 15;
= 36 ÷ 540 = 1/15
