Matching quantities with units
Mrrafil [7]

Answer:

1. Volume = length x width x height => cubic centimetres.

2. Perimeter = 2(length) + 2(width) => metres.

3. Speed = Distance /time => metres per second.

4. Area = length x width => square metres.

Step-by-step explanation:

1. Volume = length x width x height

If the length, width and height are measured in centimetre (cm) , then, the unit of the volume will be:

Volume = cm x cm xcm = cm3 i.e cubic centimetres.

2. Perimeter = 2(length) + 2(width)

If the length and width are measured in meter (m), then, the unit of the perimeter will also be in metre (m).

3. Speed = Distance /time

If the unit of distance is measured in metre (m) and the time is measured in second (s), then , the unit of the speed will be:

Speed = Distance /time = m/s i.e metres per second.

4. Area = length x width

If the length and width are measured in metres (m), then, the unit of the area will be:

Area = m x m = m2 i.e square metres

MR. ARCEO TAKES A TAXI FROM THE AIRPORT TO A HOTEL. THE TAXI CHARGES $2.50 INITIAL CHARGE PLUS $2.65 PER MILE. WHICH EQUATION CA
enyata [817]
2.65x + 2.50 = y

step by step explanation:

2.65 is how much for each mile, and the variable, x, represents the number of miles of the trip. so, we would do 2.65x to find out how much money you have to pay for the amounts of mile.

next, you would have to add the initial fee, which is 2.50. so 2.65x+2.50.

lastly, y represents the total cost of the trip. so, 2.65x + 2.50 = y
