Answer:
52.8%
Step-by-step explanation:
The amount of alcohol is:
0.28 (6 pints) + 0.90 (4 pints) = 5.28 pints
So the concentration is:
5.28 pints / 10 pints × 100% = 52.8%.
Answer:
It is the distance around a circle.
Step-by-step explanation:
Answer:
25.7 m
Step-by-step explanation:
Hello!
We have two sides each measuring 5m, so the length of the straight edges is 2(5m) or 10m
We also have two identical semi-circle circumferences, so if we find the circumference of the whole circle, we can find the total length of the curved edges.
- C = 2πr
- C = 2(3.14)(2.5)
- C = 5(3.14)
- C = 15.7
Now, we can add up the two lengths:
- Perimeter = straight sides + curved sides
- Perimeter = 10m + 15.7m
- Perimeter = 25.7m
Answer:
SSS or SAS
Step-by-step explanation:
Remark
Since the two diagonals bisect each other, you have created two sets of equal lines. If that is the case, then you could prove the equality of the triangles 2 different ways.
1) The angles at the center are vertically angles which makes them equal. Since they are equal, the triangles are congruent by SAS. Notice that the angle is between the 2 equal sides.
2) Since CD and AB are marked as being equal, the triangles are congurent by SSS.
