A football team won 75% of 120 games in a season . how many games is that

insens350 [35]

Hey! First you do 120 divided by 4 which equals 30 then you do 30 x 3 which is 90 which equals 90. So they won 90 games and lost 30 games.

Hope this helps!

Find the volume of the solid under the plane 3x+2y−z=0 and above the region enclosed by the parabolas y=x^2 and x=y^2.

Yuri [45]

The region in the x-y plane is the set of points

$R=\{(x,y)\mid0\le x\le 1,x^2\le y\le\sqrt x\}$

The height of the solid falls between the x-y plane (for which z = 0) and the equation of the plane, z = 3x + 2y.

So the volume is

$\displaystyle\int_0^1\int_{x^2}^{\sqrt x}\int_0^{3x+2y}\mathrm dz\,\mathrm dy\,\mathrm dx$

$=\displaystyle\int_0^1\int_{x^2}^{\sqrt x}(3x+2y)\mathrm dy\,\mathrm dx$

$=\displaystyle\int_0^1(3x^{3/2}+x-3x^3-x^4)\,\mathrm dx$

$=\displaystyle\frac65+\frac12-\frac34-\frac15=\boxed{\dfrac34}$

M=B

First we will prove that the diagonals are bisectors of each other.

Angle DBA is congruent to angle BDC.

Angle CMD is congruent to angle AMB.

Triangle CMD is congruent to triangle AMB.

Segment AM is congruent to segment MC.

M is the midpoint of segment AC.

Segment BD bisects segment AC.

Segment BM is congruent to segment MD.

M is the midpoint of segment BD.

Segment AC bisects segment BD.

Then we will prove that the diagonals are perpendicular to each other.

10. Segment CD is congruent to segment CB.

11. Segment BM is congruent to segment MB.

12. Segment CM is congruent to segment CM.

13. Triangle CDM is congruent to triangle CBM.

14. Angle CMD is congruent to triangle BMC.

15. Angle CMD + angle BMC = 180

16. Angle CMD = 90 and angle BMC = 90

17. Angle AMB = 90

18. Angle CMD is congruent to angle DMA.

19. Angle DMA = 90

20. Segment AC is perpendicular to segment BD.

The area of the rectangle is 54 units squared. Write and solve an equation to find x.

lord [1]

Answer: $x=5$

Step-by-step explanation:

The area of a rectangle can be found with the following formula:

$A=lw$

Where "l" is the length and "w" is the width.

In this case you can identify in the figure given in the exercise that:

$l=4x-2\\\\w=3$

You know that the area of that rectangle is the following:

$A=54$

Therefore, knowing those values, you can substitute them into the formula and then you must solve for "x" in order to find its value. You get that this is:

$54=(4x-2)(3)\\\\54=12x-6\\\\54+6=12x\\\\\frac{60}{12}=x\\\\x=5$
