Answer:
C) 12 m
Step-by-step explanation:
The length of the line segment using the percentage are as follows:
25% length = 1 cm
50% length = 2cm
100% length = 4 cm
75% length = 3 cm
<h3>How to find length with the percentage?</h3>
The line segment 8 cm is 200% . This means it is double of 100%.
Therefore the length can be calculated using the percentage as follows;
100% length = 8 / 2 = 4 cm
Hence,
75% length = 75 / 100 × 4 = 3 cm
Hence,
25% length = 25 / 100 × 4 = 1 cm
50% length = 50 / 100 × 4 = 2cm

Answer:
153.94
Step-by-step explanation:
A = pi * r^2
A = pi * 7^2 (radius is half of the diameter)
A = 49 * pi
A = 153.94
i hope this helps !!
Step-by-step explanation:
For A
The name of two similar triangles is ABC and CED.
For b
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.
Here
< BAC = < CED ( given)
<ACB = < ECD ( vertically opposite angles)
1.45×10-¹²= moving the point 12 times left
=0. 00 000 000 000 145
