Step-by-step explanation:
Scale factor of STUV to S'T'U'V
= Length of T'U' / Length of TU
= 6/12 = 0.5.
The total surface area of the shape is 516 m²
<u>Explanation:</u>
Given:
The figure consists of 6 rectangles.
2 of each rectangles are similar in dimension
Total surface area = 2 (8 X 6) + 2 (15 X 8) + 2 (15 X 6)
= 96 + 240 + 180
= 516 m²
Therefore, total surface area of the shape is 516 m²
Answer:
The sequence is the ratio of 4:8, or 16:32. This is because the sequence needs to be divided into 2 different factors in order for it to match. The sequence is...
add 4, add 8, add 16, continue on.
The formula is...
4 * x = sequence
In this case, <em>x</em> is the increasing factor. I substituted it due to the fact that it's a constantly increasing number, not just a straight-up number we can declare.
