Answer:
Step-by-step explanation:
We can write down the total size of the wildflower after the third week.
The size can be determined assuming it is a rectangle and therefore the area is:
Answer:
The system shown is consistent ⇒ A
Step-by-step explanation:
A consistent system of equations has at least one solution
- The consistent independent system has exactly 1 solution
- The consistent dependent system has infinitely many solutions
An inconsistent system has no solution
In the system of equations ax + by = c and dx + ey = f, if
- a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutions
- a = d, b = e, and c ≠ f, then the system is inconsistent and has no solution
- a ≠ d, and/or b ≠ e, and/or c ≠ f, and ≠ , then the system is consistent independent and has exactly one solution
From the given graph
∵ The two lines intersected at one point
∴ This point lies on the two lines
→ That means this point satisfies the equations of the lines
∴ The system of equations represented by the two lines has 1 solution
→ By using rule 3 above
∴ The system shown is consistent
Answer:
Since the required energy is less than the produced energy, the power is sufficient to light 9 light bulbs.
Step-by-step explanation:
A power plant has 4 tons of coal. A ton produces 2,460 kilowatt hours of electricity.
It takes 876 kilowatt hours of electricity to power a 100-watt light bulb for a year.
We have to light 9 bulbs a year.
So the required energy = 9 876 = 7884 kilowatt hours.
Power plant produces 4 tons of coal, so power = 4
= 9840 kilowatt hours.
Since the required energy is less than the produced energy, the power is sufficient to light 9 light bulbs.
Answer:
B=<em>YZ</em>/20<em>A</em>

Answer:
Step-by-step explanation:
Rectangular prisms have F=6 faces and E=12 edges.
By cutting one corner, we are adding 3 edges.
By cutting two corners, we are adding 2*3 = 6 edges.
Therefore the new solid has 12 + 6 = 18 edges.
