Á size 8 kids shoe measures 9 2/3 inches. if 5 pairs of size 8 shoes are lined end to end, then how many inches will they cover?

castortr0y [4]

5 pairs of shoes = 10 shoes

$9\frac{2}{3} \times (5 \times 2) \\ \\ = 9 \dfrac{2}{3} \times 10 \\ \\ = 96\dfrac{2}{3}$

They will cover 96 2/3 inches.

Hope this helps. - M

Which expression is equivalent to 12x+3y−9x ?

Stels [109]

The answer is 6x

You have to add 12 and 3 which is 15 then you have to do 15 minus 9 then it is 6 then you will put the x there because it had 2 x and 1y so 6x is the answer

Compute single integral of y^2 dx +x dy where C is the circle x^2+y^2=16 oriented positively

mixas84 [53]

Parameterize $C$ by

$\vec r(t)=\langle x(t),y(t)\rangle=\langle4\cos t,4\sin t\rangle$

with $0\le t\le2\pi$ . Then

$\displaystyle\int_Cy^2\,\mathrm dx+x\,\mathrm dy=\int_0^{2\pi}\langle y(t)^2,x(t)\rangle\cdot\left\langle\frac{\mathrm dx(t)}{\mathrm dt},\frac{\mathrm dy(t)}{\mathrm dt}\right\rangle\,\mathrm dt$

$=\displaystyle\int_0^{2\pi}\langle16\sin^2t,4\cos t\rangle\cdot\langle-4\sin t,4\cos t\rangle\,\mathrm dt$

$=\displaystyle16\int_0^{2\pi}(\cos^2t-4\sin^3t)\,\mathrm dt=\boxed{16\pi}$

15PTS PLEASE HELP ASAP!!<br> (dont write random answers pls!)

ikadub [295]

Answer:

to find the answer, you need to find the measure of the angle on the other side of the 142. and since it's a straight line, those two angles measures are =to 180 (they're supplementary angles). so the measure of that angle is 38 degrees. to find the measure of the remaining angle, you subtract the angle measures you already know from 180 (because the sum of interior angles in a triangle is 180.) to, the answer is:

180-90-38= 52 degrees or A
