Which two solid figures have the same volume? A. An oblique solid with a base of 4 cm2 and a height of 8 cm B. A cone with a bas
kkurt [141]

In general, Volume is equal to the area of the base multiplied by the height.

Let's check the volume of each.


A.

V=area of base x height, all given, so,

V=4*8=32


B.

Volume of cone is given by,

V= one-third area of base x height, all given, so,

V=\frac{1}{3}*4*8= \frac{32}{3}


C.

Here, the slant height is given, not the altitude (height). The volume is not 32 nor \frac{32}{3}.


D.

Rectangular solid's volume is area of base times height, all given, so,

V=4*8=32


Hence, A and D have same volume.

ANSWER: Option A and Option D have the same volume (32)

Solve this system of linear equations. Separate
Arte-miy333 [17]

Answer:

x = -7, y = -1

Step-by-step explanation:

Solve the following system:

{3 y - 2 x = 11 | (equation 1)

2 y + 3 x = -23 | (equation 2)

Swap equation 1 with equation 2:

{3 x + 2 y = -23 | (equation 1)

-(2 x) + 3 y = 11 | (equation 2)

Add 2/3 × (equation 1) to equation 2:

{3 x + 2 y = -23 | (equation 1)

0 x+(13 y)/3 = -13/3 | (equation 2)

Multiply equation 2 by 3/13:

{3 x + 2 y = -23 | (equation 1)

0 x+y = -1 | (equation 2)

Subtract 2 × (equation 2) from equation 1:

{3 x+0 y = -21 | (equation 1)

0 x+y = -1 | (equation 2)

Divide equation 1 by 3:

{x+0 y = -7 | (equation 1)

0 x+y = -1 | (equation 2)

Collect results:

Answer: x = -7, y = -1
