Split it up
small square on top with side legnths s and s
big squaer with legnth and width 5s and 3s

area=legnth times width

total area=5s*3s+s*s=15s^2+s^2=16s^2

toatl area=600
600=16s^2
divide both sides by 16
37.5=s^2
squer root both sides6.12372
tenth
6.1 mm is s

s=6.1mm

A train leaves Los Angeles at 2 p.m. heading north at 50 mph. If the next train leaves three hours later and also heads north at

Mamont248 [21]

Since the first train has been travelling for 3 hours, we have the following equations:
$d=50t+3*50=50t+150$
$d=60t$

We want to know when they will be equal, so set these equal to eachother:
$60t=50t+150$
$10t=150$
$t=15$

So 15 hours after the second train leaves, they will be at the same distance. This is at 8AM since the second train leaves at 5PM.

A company has budgeted 5 1/4 hours to complete a project, with 1/3 of the time spent on research. How much time does the company

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.
