Answer:

The first one, the third one, and the fourth one.

Step-by-step explanation:

i just put the ones that are correct. If you want me to write out why the incorrect ones are incorrect, let me know.

-6=3x

-6= 3(-2)

-6= -6

3. -8= x+x+x+x

-8= -2+-2+-2+-2

-8= -8

4. x/2= (-1)

-2/2 =(-1)

-1= -1

Answer:

7 ounces of trail mix each hiker receive.

Step-by-step explanation:

Given:

Milton makes a trail mix for his hiking group. He mixes 1 1/4 pound of peanuts, 14 ounces of raisins, 12 ounces of walnuts, and 10 ounces of chocolate chips.

If Milton divides the trail mix equally among the 8 hikers in the group.

Now, to find the ounces of trail mix each hiker receive.

Pound of peanuts = $1\frac{1}{4}.$

Now, using conversion factor convert pound into ounces:

1 pounds = 16 ounces.

$\frac{5}{4}$ pounds = $\frac{5}{4} \times 16$ = $20\ ounces.$

Ounces of peanuts = 20.

Ounces of raisins = 14.

Ounces of walnuts = 12.

Ounces of chocolate chips = 10.

Now, we add all the ounces of peanuts, raisins, walnuts and chocolate chips to get the trail mix:

$20+14+12+10\\\\=56\ ounces.$

Total ounces of trail mix = 56.

Total number of hikers = 8.

As given, Milton divides the trail mix equally among the 8 hikers.

So, to get the trail mix each hiker receive we divide total number of hikers by total ounces of trail mix:

$56\div 8$

$=7\ ounces.$

Therefore, 7 ounces of trail mix each hiker receive.

Evaluate the line integral using the fundamental theorem of line integrals. use a computer algebra system to verify your results

mario62 [17]

$\dfrac{\partial f}{\partial x}=\cos x\sin y\implies f(x,y)=\sin x\sin y+g(y)$

$\dfrac{\partial f}{\partial y}=\sin x\cos y=\sin x\cos y+\dfrac{\mathrm dg}{\mathrm dy}$
$\implies\dfrac{\mathrm dg}{\mathrm dy}=0\implies g(y)=C$

$f(x,y)=\sin x\sin y+C$

$\displaystyle\int_{\mathcal C}\cos x\sin y\,\mathrm dx+\sin x\cos y\,\mathrm dy=\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=f\left(\frac{3\pi}2,\frac\pi2\right)-f(0,-\pi)=-1$

Oksana_A [137]

Answer:

Yes

Step-by-step explanation:

B is a subset of A because if A= {0,1,2,3,4} and B= {1,2} B is a part of A and B is a smaller version of A

Don't know if this helps but this is how I learned subsets.
