Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
2^-2
Is 1/2^2=1/4
3 x 1/4 is 3/4
The answer is 3/4 I think
So the problem ask to what could be the right choice among the three that could support the said statement in you problem that tells that an angle that has a supplement also has a complement and the best answer would be that it is ALWAYS be TRUE. I hope you are satisfied with my answer
Answer:
Step-by-step explanation:
This is just an addition question. If you have a calculator just add the numbers.
3.25 + 1.625 = 4.875 cups in the bowl.
Sometimes you can use another method. Sometimes it is shorter.
3 1/4 + 1 5/8 = 3 2/8 + 1 5/8 = 4 7/8.
7/8 = 0.875
Answer: 42 feet
Step-by-step explanation:
Let the length be x
Therefore, width = 2/3x
Area = Length × Width
Therefore, x × 2/3x = 1176
2/3x² = 1176
Divide both side by 2/3
x² = 1176 ÷ 2/3
x² = 1176 × 3/2
x² = 1764
x = ✓1764
x = 42
The length is 42 feet
