Answer:
x=120, y=70
Step-by-step explanation:
X must be 120 degrees as it is on a parallel line.
The outer+interior angles of a triangle on a straight line must be supplementary, so the second angle of the triangle is 180-120=60.
All interior angles of a triangle add up to 180 degrees: 50+60+y=180
y+110=180
y=70
Answer:
The answer would be 5.
Step-by-step explanation:
If you take away 18 from 90 would be 72.
72 - 18 =54
54 - 18 =36
36 - 18 =18
18 - 18 =0
If you count that would equal 5 .

2 1/2 pounds of apple makes serve 6
(2 1/2 x 24)/6 = 10 pounds of apple will make serve 24.
Therefore, she will use 10 pounds of apples.
Answer:
75
Step-by-step explanation:
Divide 50 by 2/3. Division is the same as asking "how many times can i subtract 2/3 from 59?"
Dividing by a fraction is the same as multiplying by the reciprocal.
You can subtract 2/3 from 50, 75 times
Area = π x radius²
dA/dr = 2πr
Average rate of change = (rate of change at one instant + rate of change at other instant)/2
= (2πr₁ + 2πr₂)/2
= (r₁ + r₂)π
Ai) 9π
Aii) 8.5π
Aiii) 8.1π
B) Instantaneous change:
(dA/dr) at (r = 4) = 2π(4)
= 8π
