#### Linda works at a pharmacy for \$15 an hour. She also babysits for \$10 an hour. Linda needs to earn at least \$90 per week, but she does not want to work more than

I am really lost on this question. I thought I knew what it was, but when I looked in the book I was incorrect. If possible, I need all the work shown.

Let x equal the number of hours at the pharmacy and y equal the number of hours babysitting. Then

15x +10y = 90

Now the last part of your question did not show up above but I am assuming that the total hours where specified, let call that T. So the second equation is:

x + y = T

Then these equations can be solved by substitution or any other preferred method of solving simultaneous equations.

#### 2,6,12,20,30, ,56 what is the value in the blank in this sequence?

Asked by Alif from New York, NY

The difference between the first and second numbers is 4, between the second and third is 6, between the third and fourth is 8. What do you notice about this? Is it a pattern that continues?

#### Physics Questions

A 0.14kg pinecone falls 16m to the ground, where it lands with a speed of 13m/s.  With what speed would the pinecone have landed if there had been no air resistance?

The potential energy of the pinecone before it drops is mgh (given the ground is used as the zero potential energy reference). After if falls the energy is all kinetic energy or (1/2)mv^2 Equating these gives v^2 = 2gh. Note that you can now determine the energy loss due to air friction by the difference in kinetic energy of the two cases. You will need the mass for this calculation.

#### In Physics, how do I go from a velocity vs. time graph to a position vs. time graph?

I have the velocity vs. time graph already, I just need to change it to position vs. time.

Just in case you are not taking a calculus level class, the position can be deterimined by the area under the curve of the velocity graph up to the time in question. If the graph drops below the x axis, count this as negative area.

#### Melissa drove at an average speed of 45 mi/h from her home in Memphis to visit her sister in Atlanta.

Melissa drove at an average speed of 45 mi/h from her home in Memphis to visit her sister in Atlanta. She stayed in Atlanta 10 hours, and on the trip back averaged 60 mi/h. She returned home 43 hours after leaving. How many miles is Memphis from Atlanta?

) Write an equation using the information as it is given above that can be solved to answer this question. Use t as your varible to represent the amount of time Melissa spent driving from Memphis to Atlanta.

Asked by Treena from Fox Island, WA

We know from the first part that the distance is equal to the speed multiplied by the time

d = st, or d = (45 mi/hr)t

we also know from the last part this same distance is

d = (60 mi/hr)(43 mi - 10 mi - t), or (60 mi/hr)(33 hr - t).

Now elliminate the d

(45 mi/hr)t = (60 mi/hr)(33 hr - t)

and solve for t.

Note: In professional work it is always a good idea to keep track of the units this way (they operate mathematically the same way as variables). But for this math problem it may be best to drop them. Do what's best for you though.
