A carton of apples weighs 25.7 pounds. Michael orders 21 cartons. How much did all the cartons weigh?

539.7

Step-by-step explanation:

Multiply 25.7 to 21 to get the answer.

539.7 pounds

Step-by-step explanation:

you have 21 cartons and each one weights 25.7 pounds so you do 21•25.7=539.7

36 units

Step-by-step explanation:

Each square present in the graph shows the distance of four units. Now it is defined in the question, that Joe always travelled in a straight line. So first he went to David's house. He travelled seven boxes to reach David's house.

Each box = 4units

So, for 7 boxes,

7 x 4 = 28 units (A)

Now they both went to swimming pool which is at the distance of two units from David's house

So they both travelled two boxes.

Distance from David's house to swimming pool is 2 boxes

Each box = 4units

2 x 4 = 8 units (B)

So total distance Joe travelled = A + B

total distance Joe travelled =  28 + 8

total distance Joe travelled =  36 units
