Answer:

B = 63 degrees

Step-by-step explanation:

Right triangles add up to 180 degrees and they give you the information of 27 degrees for A and the right angle which equals 90 degrees. Those two things add up to 117 degrees. Subtract 180 degrees by 117 degrees and you get the missing measurement which is 63 degrees. Hope this helped!

so first off, let's simplify both equations, starting off by multiplying both sides by the LCD of all fractions, to do away with the denominators.

$\bf \cfrac{10(x-y)-4(1-x)}{3}=y\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{10(x-y)-4(1-x)=3y} \\\\\\ 10x-10y-4+4x=3y\implies \boxed{14x-13y=4} \\\\[-0.35em] ~\dotfill\\\\ 7+x-\cfrac{x-3y}{4}=2x-\cfrac{y+5}{3}\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{12}}{12\left( 7+x-\cfrac{x-3y}{4} \right)=12\left( 2x-\cfrac{y+5}{3} \right)} \\\\\\ 84+12x-3(x-3y)=24x-4(y+5) \\\\\\ 84+12x-3x+9y=24x-4y-20\implies \boxed{-15x+13y=-124}$

now, let's do some elimination on those two simplified equations.

$\bf \begin{array}{cllcl} 14x&-13y&=&4\\ -15x&+13y&=&-124\\\cline{1-4} -x&&=&-120 \end{array}~\hfill x=\cfrac{-120}{-1}\implies \blacktriangleright x=120 \blacktriangleleft \\\\\\ \stackrel{\textit{substituting on the 1st equation}}{14(120)-13y=4}\implies 1680-13y=4\implies 1680-4=13y \\\\\\ 1676=13y\implies \blacktriangleright \cfrac{1676}{13}=y \blacktriangleleft \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill \left( 120~,~\frac{1676}{13} \right)~\hfill$

A cylindrical container of three rubber balls has a height of 18 centimeters and a diameter of 6 centimeters. each ball in the c

You have 3 spheres inside a cylinder like for a can of tennis balls. Notice the radius of the cylinder is 3 cm, the same as the radius of the spheres, so the spheres just fit width wise, and 3 spheres height would be 6 radius lengths or 18, which is the same as the cylinder height, so the three spheres are packed to the best fit.

The volume not occupied by the spheres will be the total cylinder volume take away the three spheres volumes.

The cyinder volume with height h=18 and radius r=3 will be approx..
$V cyl= \pi r^2h = \pi *3^2*18 = 508.7 ~cm^3$

The volume of 3 spheres with radius r=3 will be
$3*V sph=3* \frac{4}{3} \pi r^3=3* \frac{4}{3} \pi *3^3=339.12~cm^3$

The volume unoccupied by the spheres inside the cylinder is the difference in those two volumes..
508.68 - 339.12 = 169.56 or 170 cubic centimeters
