Yes, I believe they did. But do you know what items each Native American group bartered with? Thank you!

If a cart and rider are pulled with a constant force of 74.0 N, and the friction force is 29.0 N, how fast will the cart and rider be traveling after 8.70 seconds? Thanks a lot!

First, you need to combine like terms. 4x=480 Then, divide each side by 4. 4x/4=480/4 4's on the left side cancel out, leaving: x=120 Adults(3x):360 Students(x):120

**Algebra**

Simplify rt= 1/[(1/r1)+ (1/r2)] That looks like the formula for the "total" resistance, rt, of two resistors in parallel, r1 and r2. The t, 1 and 2 are subscripts. It cannot be made much simpler than that, but it can be rewritten 1/rt = 1/r1 + 1/r2 which is a bit ...

Simplify r=1/(1/x+1/y) multiply the right side by xy/xy

**Algebra**

Simplify 1/r=1/x+1/y Multiply both sides by rxy. Then simplify. I will be happy to check your work. That is as compact and simple as the relationship can be written. Are you looking for an explicit formula for x, y or r?

**Algebra**

Find all positive values for k for which each of the following can be factored. X^2-x-k (Your answer seems to be the same as the other problem x^2+x-k ) Is this correct too? Consider your equation to be in the form ax^2 + bx = c = 0. It can be factored (that is, have real ...

**Algebra**

Find all positive values for k for which each of the following can be factored. X^2-x-k Using the quadratic equation, x= 1/2 +-1/2* sqrt (1+4k) Now, the sqrt has to be of a positive number, so 1+4k>0 so any value of k>-1/4 should work.

**distance formula**

Hey thanks, stupid negative..... Ok now I'm trying to figure out the distance formula. the coordinates are (-1,3) and (2,5) So I take (5-3)^2 + (2-1)^2 and get 2^2 + 1^2. so 4 + 1 is 5. so the square root of 5 is the answer? your second subtraction is wrong it should be (2...

**math problem**

I'm trying to get a handle on what square roots are (I think thats what they are called). Here is an example. 4(almost like a division sign but it is more like a check mark)3. I don't understand what it is, its a square root? and How do I deal with these things? A ...

**Circles.**

Ok I'm trying to find the radius of a circle with the given measurement. 4/5C=17 C stands for Circumference. Solve for C (multiply both sides by 5/4) Then, solve for radius R= C/2PI

**Math**

How do I figure out the height of a triangle? The height of a triangle is defined as the perpendicular distance from an angle to a side. Now, since this is a right triangle, and depending on how it is situated, the height could be 10" or 12" if you observe from the ...

**Alegebra 1B**

7x/16-x/16 When you have the same denominators (numbers on the bottom), you can just subtract the numerators (#s on the top) So 7x-x = 6x So the answer is 6x/16 Matt x-5+(-6)-6=0 x-5+(-6)-6=0 wa zup i think she is right i mean she is right

I really need help with my science lab. I was sick when we did the lab on Thursday and Friday was a snowday so I did not get to get the observations off my peers. My teacher has allowed people one more day and I do not understand this Lab at all. If someone could help me write...
