(-2/3)*(-2 1/4)*(3/4) Convert the mixed fraction to improper fraction.
(-2/3)*(-9/4)*(3/4) Then you multiply the numerators with numerators and denominators with denominators

(-2*-9*3) negative times negative is positive, so the negative sign is gone
-------------
(3*4*4*) The lines (-----) is the line of the fraction

54/48 This is the product of this multiplication, now you need to simplify
by reducing the numbers of the fraction

9/8 And that would be the answer

madeline studies honeybees. every week she weighs the same honeybee hive, the first week the hive weighs 11.607 kilograms. its w

fomenos

So, we already know that one hive has a weight of 11.607kg and .204kg is add each week, so we add on .204kg times, w, representing weeks onto 11.607kg and our t is our total of weight of a hive with respect to weeks

$w = weeks \\ t = total \: weight \: with \: respect \: to \: weeks$
So in this case our w is 7.5 weeks and now we evaluate t

$w = 7.5 \: weeks \\ t = ?$
Solve
$11.607kg + .204kg(w) = t \\ 11.607kg + .204kg(7.5) = t \\ t = 13.137kg$
Answer:

Hive's weight will increase by 1.53kg in 7.5 weeks to 13.137kg

Question 2

kari74 [83]

Answer:

7:55 am

Step-by-step explanation:

To determine the time needed to leave, add up all of the elapsed time and subtract that from the 8:50 departure time. The 10 minutes from walking to the platform puts us at 8:40 am, 30 minutes to reach the station puts us at 8:10 am, and the extra 15 minutes gives a time of 7:55 am.
