elena-s [515]

Given that a company budgeted 5 1/4 hours to complete a project, determine how much time they spent on research if they spent 1/3 of the total budget.

First, convert the budget from hours into minutes.

5 1/4 hours = 315 minutes

1 hour = 60 min

1/4 hour = 15 min

60 x 5 = 300

300 + 15 = 315

Then, divide the minutes by 3 or multiply it by 1/3.

315 / 3 = 105

315 x 1/3 = 105

Lastly convert to a mixed number.

1 3/4 hour

Thus, the company plans to spend 1 3/4 hours or 1 hour and 45 minutes on research.

DENIUS [597]

Let g be the number of grandchildren, and d be the number of dogs. They both have only one head, so the number of heads is

g+d=33

Grandchildren have 2 legs, while dogs have 4. So, the total number of legs is

2g+4d=84

From the first equation (the one for the heads) we can derive

g=33-d

Substitute this into the second to get

2g+4d=84 \implies 2(33-d)+4d=84 \iff 2d=18 \iff d=9

So, there are 9 dogs and (from the first equation

g=33-9=24
