You have to add the factions:
2 1/5kg + 2 2/5
Add the whole numbers: 2 + 2 = 4
Add the fractions 1/5 + 2/5 = 3/5
Answer: 4 3/5
Answer:
100 degrees
Step-by-step explanation:
Angle 1 + Angle 2 = 180 degrees (linear pair theorem)
Angle 2 = Angle 6 (verticle angles theorem)
Thus, we can substitute the given values of angle one and angle six into the following equation:
Angle 1 + Angle 6 = 180
4x - 20 + 5x - 25 = 180
9x - 45 = 180
9x = 225
x = 25 degrees
Angle 2 = Angle 6
5x - 25 = Angle 6, so 5x - 25 = Angle 2
5(25) - 25 = Angle 2
100 degrees = Angle 2
These are congruent by SAS. or C
Answer: 9.6
Step-by-step explanation: I did a proportion, 2.4/1.5=?/6 so 6/1.5= 4 so 2.4*4= 9.6
So a person can walk 9.6 miles in 6 hours.
Hope this helps!
Answer:
Is there an error in the question? it has BC = 27 twice and we don't know much about the other sides. Anyway let's try
Step-by-step explanation:
You are told that to go from WXYZ to ABCD the scale factor is 2/3, which means that you multiply by 2/3. So to go the other way round, from ABCD to WXYZ which is what you want, you divide by 2/3, or multiply by 3/2.
So, to find XY you multiply the right side from ABCD by 3/2. I think BC is the right side?
So XY = 27 × 3/2
XY = 81 / 2 or 40.5 or 40 1/2
