Y=7x-19

-2x+3(7x-19)=-19
-2x+21x-57=-19
19x-57=-19
19x=38
x=2

-7(2) + y = -19
-14 + y = -19
y=-5

A cylindrical container with a radius of 5 cm and a height of 14 cm is completely filled with liquid. Some of the liquid from th

Flura [38]

Answer:

The remaining liquid has a volume of 345.4 cm³.

Step-by-step explanation:

To solve this question we first need to calculate the volume of each container.

Cylindrical:

Volume = h*pi*r² = 14*3.14*(5)² = 1099 cm³

Cone:

Volume = (1/3)*h*pi*r² = (1/3)*20*3.14*(6)² = 753.6 cm³

Since the liquid from the cylinder was transfered to the cone until the latter was full, then what remains in the cylinder is it's original volume minus the cone volume. So we have:

remaining liquid = 1099 - 753.6 = 345.4 cm³

In triangle ABC, a = 5.3 cm, b = 4.8 cm, and c = 9.2 cm.

suter [353]

Answer:

a= 25.69, b=23.12, c=131.119

Step-by-step explanation:

$cosa=\frac{B^{2} +C^{2} -A^{2} }{2BC} \\ =\frac{79.59}{88.32} \\ a = 25.69$

$cos(b)=\frac{A^{2} +C^{2} -B^{2} }{2AC} \\ =\frac{89.69}{97.52}\\ b=23.12\\c=180-23.12-25.69\\ = 131.119$
