a honey bee gathered nectar for 3/4 of an hour. it returned to the hive every 1/12 hour. how many trips did the bee make ?

alekssr [168]

Divide.

3/4 / 1/12

Flip the 2nd fraction and multiply:

3/4 * 12/1

Multiply the numerators and denominators together:

36/4

Divide:

9

So the bee made 9 trips.

you burn 10 calories each minute you jog.What integer represents the change in your calories after you jog for 20 mins

Hoochie [10]

The total calories burnt in 20 minutes are 200

Step-by-step explanation:

We have to do simple multiplication to find the number of calories burnt.

Given

Number of calories burnt in one minute = c = 10

Time = t = 20 min

So the total number of calories burnt in 20 minutes will be:

$C_t = c * t\\= 10 * 20\\=200\ calories$

Hence,

The total calories burnt in 20 minutes are 200
