Answer:
5
Step-by-step explanation:
Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.
Let x be the number of questions, solving by trial and error:
Therefore, the minimum number of questions in the game is 5.
Answer:
x = 15 degrees
3 angles in triangle are 44, 44 and 92 degrees.
Step-by-step explanation:
When the lines are parallel the internal angles add up to 180 degrees. So:-
8x + 7 + 2x + 23 = 180
10x + 30 = 180
10x = 150
x = 15
In the triangle:-
The angle adjacent to 136 = 180 - 136
= 44 degrees. As 2 sides of the triangle are congruent the other base angle = 44 degrees also.
The third angle = 180 - 2(44) = 92 degrees
Answer:
0.38 < 0.70
Step-by-step explanation:
1 hour 30 mins because you add up the minutes from both individually and then subtract.
R=I+6 S=4R I
I+(I+6)+4(I+6)=126
Basic algebra (I dont know how to show it) leaves you with: 6I = 90, divide both sides by 6 and I=15
