What set of transformations is performed on triangle RST to form triangle R’S’T’?
ra1l [238]

Answer:

D. A translation 2 units down followed by a 270-degree counterclockwise rotation about the origin

Step-by-step explanation:

The given triangle has vertices at R(3,4), S(1,1), and T(5,1)

Translating the the vertices down by 2 units, we apply the rule;

(x,y)\to (x,y-2)

\implies (3,4)\to (3,2)

\implies (1,1)\to (1,-1)

\implies (5,1)\to (5,-1)

Rotating the resulting vertices through an angle 270 degrees counterclockwise, we apply the rule:

(x,y)\to (x,-y)

\implies (3,2)\to R'(2,-3)

\implies (1,-1)\to S'(-1,-1)

\implies (5,-1)\to T'(-1,-5)

Therefore the correct choice is D.

On farm there are 200 cows from those 200 cows there are 150 cows that can give milk .in one corral there are 20 cows. How many
LiRa [457]

Here the two samples should be comparable .

The total number of cows in the farm = 200

the total number of cows giving milk = 150

the total number of cows in corral = 20

Suppose total number of cows giving milk in corral = x

The ratio of the total number of cows present to the total number of cows giving milk should be same in farm and corral

so : 200 = 20

------- -------

150 x

now we do cross multiplication :

200 x = 150* 20

200x = 3000

x= 3000/200

x= 15

SO we expect 15 cows in corral should be giving milk .

Answer : 15
