The required value of y is 2645 / 77 when x = 77.
Step-by-step explanation:
1. Let's check the information given to answer:
if y varies inversely as x, and y = 23 when x = 115. Find y when x=77
2. What is y when x = 77?
As the statement "y varies inversely as x" translates into y = k/x
If we let y = 23 and x = 115, the constant of variation becomes
23 = k ÷ 115
k = 23 × 115
k = 2645
Thus the specification equation is y = 2645 ÷ x . Now, letting x = 77, we obtain
y = 2645 ÷ x
y = 2645 ÷ 77
<u>So, The required value of y = 2645 / 77 when x = 77</u>

To factor (q+3)(q+6)
q^2+6q+3q+18
q^2+9q+18
(q+9)(q+2)
The steps are more or less the same, except for one new addition:
1.Divide the tens column dividend by the divisor.
2.Multiply the divisor by the quotient in the tens place column.
3.Subtract the product from the divisor.
4.Bring down the dividend in the ones column and repeat.
You would need 3 2-dimensional rectangles and 2 2-dimensional triangles to make up a Triangular Prism.
I hope this helps!
