Answer:
119°
Step-by-step explanation:
< DBE = 180° - < ABE
or, < DBE = 180° - 61°
or, < DBE = 119°
hope it works, fanks !!
Answer:
Q = -6
Step-by-step explanation:
To find the answer to this, you first must multiply the first function by 2:
2 x (x - 3y = 4)
2x - 6y = 8
Which then means that the second function is the same. This means that to find Q you need to find the number that changed +Qy into -6:
2x - 6y = 8
2x + Qy = 8
The 2x's cancel out, and then remove the equals and the 8:
-6y = Qy
<h3>So Q must be -6</h3>

I think the shaded region for this problem will the part of the circle that is not covered by the triangle. First, determine the area of the circle by the equation,
A = πD²/4
Substituting the given diameter,
A = π(16 ft)²/4 = 200.96 ft²
Then, determine the area of the triangle with the equation,
A = bh/2
Since the base of the triangle is the diameter, b = 16 ft. Then, its height will be half the height and that will be equal to 8 ft. Substituting,
A = (16 ft)(8 ft) / 2 = 64 ft²
The difference between the two areas is 136.96 ft².
Answer: D
80 000 > 0,00004
80 000 : 0,00004 = 2 000 000 000
2 000 000 000 = 2*10^9
