Answer:
2:3
Step-by-step explanation:
from 48:72
if we divided both the number on the fraction and under the fractionby 24
the simplest form is 2:3
By doing a reflection over the x-axis and a translation two units to the left (Choice 1), we see that triangle RST is congruent to triangle ACB.
Let's test this.
R(1,1)
S(1,5)
T(4,1)
A reflection across the x-axis follows the rule of (x,-y). Doing this, we get the new points:
R(1,-1)
S(1,-5)
T(4,-1)
Then we move the triangle two units to the right. This follows the rule (x-2,y). Our new points are:
R(-1,-1)
S(-1,-5)
T(2,-1)
We can see that points R, S, and T correspond to all the points on ACB, so this answer choice is correct.

Answer:
Volume of a cylinder = 549.5 cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
Where,
π = 3.14
Radius, r = 5 cm
Height, h = 7 cm
Volume of a cylinder = πr²h
= 3.14 * (5 cm)² * 7 cm
= 3.14 * 25 cm² * 7 cm
= 549.5 cm³
Volume of a cylinder = 549.5 cm³
