Rotation, Translation, and Reflection are the 3 rigid motions that preserve angle measure and side length.
A dilation only preserves angle measure.
Therefore, the answers are A, C, and D
Percent means parts out of 100
74%=74/100=0.74
'of' means multiply
so
128 is 74% of what means
128=0.74 times what
divide both sides by 0.74
172.97297297297297297297297297297=what
the number is about 173
Answer:
C.) It is congruent to itself by the Reflexive Property of Equality.
Step-by-step explanation:
Sorry I actually read it this time and I'm in Honors Geometry and this is 100% right.
Answer:
431
Step-by-step explanation:
you take 7.75 divide it by 100 and then times it by 400
Answer:
227.75 cm
Step-by-step explanation:
a coin (Circle) with diameter 2.9cm
(radius) r = diameter ÷ 2
r = 2.9cm ÷ 2
r = 1.45cm
1 complete revolutions (perimeter or circumference of a circle ) = 2πr
= 2 × π × r
where r = radius, π is a constant = 22/7
= 2 × 22/7 × 1.45
= 9.11cm
thus in one complete revolution the coin travels a distance of 9.11cm.
therefore in 25 complete revolutions the coin will travel a distance of = 25 × 9.11 cm = 227.75 cm.
The distance covered in complete 25 revolutions of a coin with diameter of 2.9 when it's rolled is = 227.75 cm
