Step-by-step explanation:

(1) x+10y=20, x=20,y=2

(2) 6x+y=-18, x=-3,y=-18

(3) 2x-9y=-36, x=-18,y=4

(4) x=-6,y=-15

(5) x=9,y=12

(6) x=-18,y=-3

(7) x=16,y=-6

(8) x=14,y=8

(9) x=-12,y=9

(10) x=-15,y=-6

(11) x=12,y=10

The cross-sectional areas of a right triangular prism and a right cylinder are congruent. The right triangular prism has a heigh

expeople1 [14]

Answer:

The correct answer is:

The volume of the triangular prism is equal to the volume of the cylinder

Step-by-step explanation:

Given that there are two figures

1. A right triangular prism and

2. Right cylinder

Area of cross section of prism is equal to Area of cross section of cylinder.

Let this value be A.

Also given that Height of prism = Height of cylinder = 6

Volume of a prism is given as:

$V_{Prism} = \text{Area of cross section} \times Height$

$V_{Prism} = A \times 6 ........ (1)$

Cross section of cylinder is a circle.

Area of circle is given as: $\pi r^{2}$

Area of cross section, A = $\pi r^{2}$

Volume of cylinder is given as:

$V_{Cylinder} = \pi r^{2} h\\\Rightarrow V_{Cylinder} = A \times h\\\Rightarrow V_{Cylinder} = A \times 6 ...... (2)$

From equations (1) and (2) we can see that

$V_{Prism}=V_{Cylinder}$

Hence, the correct answer is:

Volume of prism is equal to the volume of cylinder.

Find sin q if q is an angle in standard position and the point with coordinates (4, 3) lies on the terminal side of the angle.

jolli1 [7]

Letâ€™s say we have a starting point (0,0), the point (4,3) are distance apart at 90 degrees, hence the hypotenuse to those two distance will be 5. Therefore sin q = 4/5.

Holly checked her answer to a division problem by estimating the quotient. Which is the best estimation of the quotient?

Andre45 [30]

Answer: 4

Try just dividing 23/5 and you’d get 4 something. But since 5.97 is close to 6 you can also mentally divide 23/6 and get 3something (it’d be really close to 4)
