Answer:
the number of circles is 3
the number of square is 9
the number of triangle is 10
Step-by-step explanation:
Let the number of square = s
let the number of circle = c
let the number of triangle = t
let the total number of the shapes = y
15 < y < 25
y = s + c + t ---- (i)
s = c + 6 ------ (ii)
c + 7 = t ------ (iii)
y = (s) + (c) + (t)
y = (c + 6) + (c) + (c + 7)
y = 3c + 13
15 < y < 25
15 < 3c + 13 < 25
15 - 13 < 3c < 25 -13
2 < 3c < 12
2/3 < c < 12/3
0.67 < c < 4
Thus, number of circle is greater 1 but less than 4
c = 3
s = 3 + 6 = 9
t = 3 + 7 = 10
Answer:
C. x = 7
Step-by-step explanation:
All angles of a square add up to 360° and there are 4 angles in every square. Since all angles of a square are 360/4 = 90, Then 12x + 6 = 90.
12x + 6 - 6 = 90 - 6
12x = 84
12x/12 = 84/12
x = 7
The answer is 64. Hope it helps you
Im pretty sure your answer is D
B) Ana is correct because 2 + 10 is greater than 10
if it were less than 10 then the last length would not be long enough to reach to the other side
