Answer:
x+5
Step-by-step explanation:
x+5
Answer:
The area is changing by the rate of 44.62 meters per sec.
Step-by-step explanation:
Let x be the side of the square and r be the radius of the circle,
Then, the area outside the circle but inside the square is,
V = Area of square - area of circle,
∵ Area of a square = side² and area of a circle = (radius)²,
Thus,
Differentiating with respect to t ( time )
We have,
x = 20 meters, r = 3 meters,
Answer:
1). t ≥ -
2). k ≥
3). y < -
4). b >
5). w ≤ 0
Step-by-step explanation:
1).
t ≥ -
2). 15k + 11 ≤ 18k - 5
15k - 18k ≤ -5 - 11
-3k ≤ - 16
3k ≥ 16
k ≥
3). 44y > 11 + 88y - 22y
44y > 11 + 66y
44y - 66y > 11
-22y > 11
22y < -11
y <
4).
(b - 27) >
b >
b >
5). 11w - 8w ≥ 14w
3w - 14w ≥ 0
-11w ≥ 0
w ≤ 0
Answer:
A
Step-by-step explanation:
Let's set up two ratios...
1 cm : 5km
8 cm : x km
Therefore the answer is A
