Answer:

Option B is the right option.

Solution,

Let the points be A and B

A(2,7)---->(X1,y1)

B(-1,4)---->(x2,y2)

Now,

$slope = \frac{y2 - y1}{x2 - x1} \\ \: \: \: \: \: = \frac{4 - 7}{ - 1 - 2} \\ \: \: \: \: \: = \frac{ - 3}{ - 3} \\ \: \: \: \: = 1$

Hope this helps..

Good luck on your assignment..

How to write a paragraph proof? Given: ∠T and ∠V are right angles TW║VU. Prove: ΔTUW≅ΔVWU

mafiozo [28]

Note: The missing diagram is attached below for a reference.

Answer:

Δ $TUW$ ≅ Δ $VWU$ by $AAS$ case.

Step-by-step explanation:

Given:

∠T and ∠V are right angles.

$TW$ ║ $VU$

To Prove:

Δ $TUW$ ≅ Δ $VWU$

∠ $T$ ≅ ∠ $V$ ≅ $90^{0}$ (Given)

Side $UW$ ≅

$TW$ ║ $UV$

and $UW$ is a transverse

So,

∠ $TWU$ ≅ ∠ $WUV$ $\left[alternate\:\:interior\:\:angles\right]$

$As\:Angle\:=\:Angle\:=\:side\:are\:equal$

Thus,

Δ $TUW$ ≅ Δ $VWU$

THE VOLUME OF A CONE IS 15 PI CUBIC METERS. WHAT IS THE VOLUME OF A CYLINDER HAVING THE SAME BASE AND SAME HEIGHT?

Drupady [299]

Okay, so I know that you either multiply the volume of a cone by 3 to get the cylinders volume, or you divide it. I think you multiply it. Just remember, the rule is to multiply the volume of a cone by 3, to get the cylinder volume with the same measurements. So 15 x 3.

A rectangular floor of area 360 m2 is going to be tiled. Each tile is rectangular, and has an area of 240 cm2. An exact number o

scoray [572]

Answer:

1500

Step-by-step explanation:

The area of the regtangular floor is 360m². The floor is going to be retired with tiles having area of 240cm² . We need to find the number of times . Therefore ,

$\implies 360m^2 = 360 \times 10^4 \ cm^2$

And , the number of tiles required will be ,

$\implies n =\dfrac{Area \ of \ floor}{Area \ of \ a \ tile }\\\\\implies n =\dfrac{ 360 \times 10^4 \ cm^2}{240 cm^2} \\\\\implies \underline{\underline{ n = 1,500 }}$

Hence the required answer is 1500 .

Find the length of AB , given that DB is a median of the triangle and AC = 50.

natta225 [31]

Since DB is the median of the triangle, it would bisect the base AC. This would mean that AB and BC are equal halves of the whole AC. So, if AC is 50, then,

AC = AB + BC
since AB = BC,
AC = 2AB
50 = 2AB
AB = 50/2
AB = 25

The answer is 25.

Red one !!! answer it pleasee

stealth61 [152]

Answer:

(6, -2)

Step-by-step explanation:

The midpoint of the segment RS is point M (5, 3). Therefore, the average of the x coordinates of R and S is 5, and the average of the y coordinates of R and S is 3. The x coordinate of R is 4. For 4 and the x coordinate of S to have an average of 5, the x coordinate of S must be 6. Therefore, our point is of the form (6, y). For 8 and the y coordinate of S to have an average of 3, the y coordinate of S must be -2. Therefore, our answer is (6, -2)
