We know there are seven days in the week, so: d e = 7 And she trains 27 hours in a week, with d 5 hour days and e 3 hour days: 5d 3e = 27 We are being asked for how many days she trains for 5 hours: d Solve: The number of "5 hour" days is 3 Check: She trains for 5 hours on 3 days a week, so she must train for 3 hours a day on the other 4 days of the week.

3 × 5 hours = 15 hours, plus 4 × 3 hours = 12 hours gives a total of 27 hours So Joel’s normal rate of pay is $12 per hour Check Joel’s normal rate of pay is $12 per hour, so his overtime rate is 1¼ × $12 per hour = $15 per hour.

Oh, yeah, kids, it’s real and it’s finally here, but not without a few kinks. And, when you turn your math work in, your teacher might get the sinking suspicion that you’re calling in some serious tech backup to get your homework done (a.k.a.

If you’re a fourth grader, you probably wouldn’t realize that Photo Math gave you the wrong answer. However, we had to significantly brighten the lighting around the math worksheet that we aimed our i Phone 6 at to coax the app into taking a clear snap, even after tapping the app’s light icon.

So over 8 years, you see that the compounding growth by 8% actually ends up being quite dramatic.

## Thinking Critically And Creatively - Word Problem Solving Calculator

Behold Photo Math, a new free photo calculator app that solves math equations in a snap -- a snap of your smartphone’s camera. Photo Math’s makers boast that their wonder product can crack basic arithmetic, fractions and decimals, powers and roots and linear equations, all in a single click. But it can’t solve handwritten or word problems -- nor, get this, a fourth-grade California Common Core Math Standards Practice Book problem we tried it out on. We also tried it on several eighth-grade algebra problems (also California Common Core issue) and it worked every time -- much to a certain 13-year-old’s delight. Step 2: Align the (homework, duh) problem you want to solve within the app’s little red frame brackets, watch a sprinkling of animated white dots sparkle while the app thinks for a second or two or three -- and Boom! The refreshingly clean and simple app, in both user interface and in functionality, is only available for i OS devices and Windows Phone for now. Before you download the app (because you know you want to, corner cutter), know that it’s not all rainbows and unicorns. The magic happens in two easy steps: Step 1: Launch the app and aim your smartphone at a math equation. Well, at least it should and most of the time it does. To see each step used to unravel the equation, just tap the word “Steps” that appears on your smartphone screen. Cue the collective mirth of math haters everywhere -- and the collective ire of math teachers the world over. Not until sometime in early 2015, according to its creators. Wonderful' on Teaching Kids About Money: ' Put Their Noses In It, Like You're Training a Puppy' Photo Math’s genius doesn’t end at the solution.So his normal pay of 40 × = 0, plus his overtime pay of 12 × = 0 gives us a total of 0 There are 12 girls!And 3b = 4g, so b = 4g/3 = 4 × 12 / 3 = 16, so there are 16 boys So there are now 12 girls and 16 boys in the class, making 28 students altogether.Let's do a couple of word problems dealing with exponential growth and decay.So this first problem, suppose a radioactive substance decays at a rate of 3.5% per hour.What percent of the substance is left after 6 hours? Remember, if you take 1 minus 3.5%, or if you take 100% minus 3.5%-- this is how much we're losing every hour-- that equals 96.5%.So let's make a little table here, to just imagine what's going on. So each hour we're going to have 96.5% of the previous hour.
