Answer: D. 26 units
Step-by-step explanation: perimeter is the distance around the figure, or all the sides added together.
With a rectangle it is known that the opposite sides are congruent, or the same, so 8+8+5+5 = 26
Answer:
1 adult cat
Step-by-step explanation:
<u>Thursday:</u>
The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.
Number of adult cats = 4x
Number of kitten cats = 3x
There were 12 kittens, then
There were 16 adult cats
<u>Tuesday:</u>

Step-by-step explanation:
Answer:
15. d) 36
16. b) 20
17. d) 180
18. b) 50
19. c) 360
20. b) 60
Step-by-step explanation:
To find the number of sides a polygon has giving an interior angle, use the equation:
(number of sides - 2)*180/(number of sides) = measure of interior angle
<em>15. </em>(n = number of sides)
((n-2)*180)/n = 170
180n-360 = 170n
10n = 360
n = 36 (d)
<em>16.</em> (n = number of sides)
((n-2)*180)/n = 162
180n-360 = 162n
18n = 360
n = 20 (b)
<em>17.</em> The sum of the interior angles of a triangle is always 180 (d)
<em>18.</em> 180-60-70 = 50 (b)
<em>19.</em> The sum of the interior angles of a quadrilateral is always 360 (c)
<em>20.</em> 360-120-90-90 = 60 (b)
