Answer:
A
Step-by-step explanation:
ok, without reading through any of the answers lets see what we can get just from looking at that picture.
We can see that the angles being bisected are on a straight line.
A straight line is 180 degrees.
We know that you have to add both angles together to get 180.
The answer has to equal 180.
A is the only option that offers that.
Answer:
20:5
Step-by-step explanation:
find how many parts (5)
25/5=5 (1 part)
5*4=20
5*1=5
Answer:
The answer is 91
Step-by-step explanation:
We have the following equality:
Then a must satisfy that 
. So,
or 
.
1) If a=7, then, it follows for the first equality that 56=14b. Then b=4. Finally, substituting b=4 in the first equality we obtain that -64=16-c. So, c= 80. We conclude that
.
As the problem states, we only consider values of a greater than zero. Then 91 is the only solution for 
.
F(x + 1) = (5/2)*f(x)
f(x + 1) = 2.5*f(x), f(1) = 3.2
f(2) = 2.5f(1) = 2.5*3.2 = 8
<span>f(3) = 2.5f(2) = 2.5*8 = 20
</span>
f(4) = 2.5f(3) = 2.5*20 = 50
<span>f(5) = 2.5f(4) = 2.5*50 = 125</span>
Sean answered 90% of the questions in the quiz correctly ^^
