35. (31-9) - 12 ÷ 2
22-12 ÷ 2
22-6
=16
36. 36 ÷ 3 +72 ÷ 9
12 + 72 ÷ 9
12+8
=20
37. 8(16-7)
8(9)
=72

Answer:
2x2=4
4+4=8
4/8 times 2 is 8/8, or 1.
Step-by-step explanation:
To find the inverse, interchange the variables and solve for y
G^-1 (x) = square root x - 1, - square root x-1
Answer: the answer is 28
Step-by-step explanation:
Answer:
So we have a triangle and a semicircle.
If the triangle is equilateral, this is:
AB = BC = 6cm
Then the area of the triangle is equal to (base*height)/2
in this case:
A = (6*6)/2 = 36/2 = 18cm^2.
And the diameter of the semicircle is equal to 6cm, then the diameter is 3cm
And if the area of a circle is A = pi*r^2
then the area of half a circle is:
A = (pi/2*)3^2 = pi*4.5cm^2
Then, the area of the triangle plus the area of the semicircle is:
Total area = 18cm^2 + pi*4.5^2
