Answer:
1. 4 hours and 10 minutes
2. 8:40 to 12:00
4. 6 hours and 50 minutes
5. 2:25 pm
6. 9:15 am to 12:35pm
7. 3:00pm
(second) 7. 2 hours and 45 minutes
Step-by-step explanation:
1. 2+4 = 6 so then after add 10 to the 45
4 hours and 10 mins
-
2. 8+3= 11 so its 11:40 right now, add the other 20 minutes, you end up with 12:00.
-
4.It's better off to start with 12 so add 3 hours and 30 minutes to get to 12:00pm. Now to 3:20pm would obviously be 3 hours and 20 minutes.
3 hours + 3 hours = 6 hours. 30 minutes + 20 mins = 50 mins. 6 hours and 50 minutes.
-
5. 10:15 + 4 hours would be 2:15 now add the 10 and that would be 2:25pm.
-
6. 9:15 a.m to 12:35pm would be right. The elapsed time is 5 hours and 20 minutes. 10:30 P.M to 1:15 A.M would be close but it's 5 minutes lesser. 11:10 pm to 2:15 am would be 3 hours and 5 minutes. 6:45pm to 10:00pm would be 3 hours and 15 minutes.
-
7. Making it simpler, add 15 minutes so that makes it 12:00pm. Then just add the 3 hours. 3:00P.M.
3:00 pm is your answer.
-
(second) 7. 10:30 pm to 1:15am. Also making it simpler, add 1 hour and 30 minutes. Now just add 1 hour and 15 minutes. Add both times,
1 hour and 30 minutes + 1 hour and 15 minutes = 2 hours and 45 minutes.
8x-77 would be the answer to this
Answer:
2x^2yz + 3xy^3z - 3xyz^3
Step-by-step explanation:
First you must distribute:
xyz(2x) + xyz(3y^2) + xyz(-3z^2)
Then simplify:
2xyxx + 3xyzy^2 - 3xyz * z^2
And finally simplify each term:
2x^2yz + 3xy^3z - 3xyz^3
Answer:
A. Actute triangle
Step-by-step explanation:
Is A because an acute triangle is a triangle where all the angles are the same.
Can not be B. because isosceles triangles have two sides that are the same which doesn't relate to angles.
Can not be C. because equilatiral triangles are triangles with sides that are all the same.
Can not be D. because for a triangle to be obtuse one of the angles needs to be greater that 90 degrees.
So it has to be A.
Answer:
Reflect over the y-axis
Step-by-step explanation:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).
Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis.
The reflection of the point (x,y) across
the y-axis is the point (-x,y).
