There is no whole number and .57 is the part...
Answer:
Exponential equations
Step-by-step explanation:
Answer:
number one. 186
number two. 36
Step-by-step explanation:
FOR NUMBER ONE:
the area of a trapezoid formula is 
where a and b are the bases and h is the height. so we have to add in the numbers into the formula
= <em>81</em>
and the paralellogram formula is b×h. where b is the base and h is height
15 × 7 = <em>105</em>
so the area of the figure is 81 + 105 is 186 in^2
FOR NUMBER TWO:
the area of the square formula is 
. where s is the side
4^2 = <em>16</em>
and for the paralellogram is b × h
4 × 5 = <em>20</em>
so the area of the figure is 16 +20 = 36 in^2
hope this helps! ;)
Answer: 100 x the original surface area of the box.
Discussion: Note that a box implies three dimensions. However, when dealing with surface area, we are dealing only with two dimensions. Therefore, scaling up a box where we have sides a, b, and c, by a factor of 10, we increase each side by a factor of 10. The scaled up box now has each of those dimensions as 10a, 10b, and 10c. Whereas the VOLUME is increased from (a x b x c) to (10a x 10b x 10c), the SURFACE AREA is increased from 2(a x b) + 2(a x c) + 2(b x c) to 2(10a x 10b) + 2(10a x 10c) + 2(10b x 10c). The SURFACE AREA is therefore kept in only square units, while VOLUME is in cubed units.
