This is true. The term congruent means that the shape is of exactly equal size. If this is true, then every side length would match for each shape. If this is true, the perimeter would also be exactly the same for each shape. Think of something that is congruent as being an exact copy of the original, with no change in size or shape.
Answer:
5.7 liters of 5% solution and 4.3 liters of 40% solution. First, create some formulas to define the problem. x Amount of 5% solution used 10-x Amount of 40% solution used This equation means 5% of x plus 40% of (10-x) equals 20% of 10. 0.05x + 0.40(10-x) = 0.20 * 10 Distribute the 0.40 0.05x + 4.0 - 0.40x = 0.20 * 10 Combine terms 4.0 - 0.35x = 2.0 Add 0.35x to both sides 4.0 = 2.0 + 0.35x Subtract 2 from both sides 2.0 = 0.35x Divide both sides by 0.35 5.7 = x So we need to use 5.7 liters of the 5% solution. To get the amount of 40% solution, just simply subtract from 10. 10.0 - 5.7 = 4.3

Answer:
2500 meals in 20 hours.
Step-by-step explanation:
The easiest point to see is (2,250). The other point (since you need 2) is the origin. This is a graph. It does not require any greater accuracy than looking at the point that is chosen.
x = 2
y = 250
k = ?
y = k*x equation
250 total meals packed = k * 2 hours Substitute values
k = 250 /2
k = 125 meals / hour
Let x = 20 hours
k = 125 meals / hour
y = ?
y = 125 * 20
y = 2500 meals
