The complete question is
Zach has 3/4 hour to play video games. it takes him 1/12 hour to set up the system. Each round of his favorite game takes 1/6 hour. How many rounds can he play
we know that
1) Zach has 
hour to play video games
Convert to minutes
2) It takes him 
hour to set up the system
Convert to minutes
3) Find time available to play video games
4) Each round of his favorite game takes 
hour
Convert to minutes
5) Divide the time available to play video games by the time each round of his favorite game
therefore
<u>the answer is</u>
.75 is the answer because it looks like division
Answer:
Step-by-step explanation:
Answer: a^3+81ab^2
First, you square (a+9b) which will become (a^2+81b^2)
Then, you multiply it by a and you will get a^3+81ab^2
Question 1:
Since the triangles are congruent, we know that QS = TV
This means that
3v + 2 = 7v - 6
Subtract both sides by 2
3v = 7v - 8
Subtract 7v from both sides
-4v = -8
Divide both sides by -4
v = 2
Plug this value back into 3v + 2 and you get 8.
QS = 8
Since the triangles are congruent
QS = 8 AND TV = 8
Question 2:
So we know that AC = AC because that's a shared side.
It's also given that BC = CD.
In order for two triangles to be congruent by SAS, the angle between the two sides must be congruent.
That means angle C must be congruent to angle C from the other triangle.
Question 3:
We know that AC = AC because it's a shared side.
We also know that angle A from one triangle is equal to angle C from the other.
However, for a triangle to be congruent by SAS, the congruent angle must be between two congruent sides.
In order for us to prove congruence by SAS, AD must be congruent to BC.
Have an awesome day! :)
