Answer:
see explanation
Step-by-step explanation:
In a parallelogram
• opposite sides are congruent
• the diagonals bisect each other
Then
UT = 27 ( congruent to RS )
ST = 18 ( congruent to RU )
VS = 7 ( congruent to UV )
VT = 15 ( half of RT )
Answer:
V = 43323 mm³
(second answer is already correct)
Step-by-step explanation:
these pennies make up the shape of a cylinder, so, we can solve this question by solving for the volume of a cylinder.
the volume of a cylinder can be found with the formula:
V = πr²h
(V = volume ; π = pi ; r = radius ; h = height)
We know the diameter of this cylinder is 19.05 mm. Diameter is two times the length of the radius, (diameter is all the way across, radius is from center to outer / halfway across) meaning that we can find the radius by dividing 19.05 by 2.
diameter = 19.05
radius = 19.05 / 2 = 9.525
so, r = 9.525
we also are given the height of this cylinder, 38 mm
so, h = 38
π = 3.14159 (π is a constant)
plugging our measurements into the volume formula:
V = πr²h
V = (3.14159)(9.525²)(38)
V = (3.14159)(362.9025)(38)
V = 43323.4894628
[rounded to V = 43323 mm³]
And yes, the volume is not affected by a change in shape. (you are correct)

Answer:
y = -3x - 5
Step-by-step explanation:
3x - y = 5
+3x +3x
-1y = 3x + 5
---- ----- -----
-1 -1 -1
y = -3x - 5
