Hey there! :)
Answer:
C) 74 units.
Step-by-step explanation:
MT is congruent to KT because the diagonals of a quadrilateral bisect each other. Therefore:
8y + 18 = 12y - 10
Subtract 8y from both sides:
18 = 4y - 10
Add 10 to both sides:
28 = 4y
Divide both sides by 4:
28/4 = 4y/4
y = 7 units. Plug this into the equation for MT:
8(7) + 18 = 74 units.

the unit rate of eggs per 1 kg of flour = 6 eggs/1 kg of flour
Step-by-step explanation:
Usually tables go in ascending numerical order...the numbers only go up, reading from right to left. But the math for this has the numbers kind of jumping around.
3/0.5 = 9/x, then cross-multiply,
3x = 9(0.5)
3x = 4.5 then divide by 3
x = 1.5
--------------------------
3/0.5 = x/1
3 = 0.5x
6 = x
----------------------------
If you need me to keep showing the math for the rest of the table, let me know.
Answer:
h = -0.0166t^2 + 30.
Step-by-step explanation:
The graph of the flight is a parabola which opens down and is symmetrical about the y axis, passes through the x axis at -42.5 and 42.5 and has a vertex at (0, 30).
So we have -a(t^2) + 30 = 0 where t is the time
(42.5)^2 * -a = -30 (42.5 as its 1/2 * 85).
a = 30/2806.25
= 0.01661
So the equation is height h = -0.0166t^2 + 30
