Big ifs, question writers. These are of course approximations.
The "co" in cosine comes from complementary angles. It means since
Answer: cos 48° = 2/3
Similarly,
Answer: tan 69.5° = 8/3
Answer:
It is a rational number
Step-by-step explanation:
It is a rational number because -6/7 is equal to -0.857142 repeating. And a rational number repeats.
Hope this helps☝️☝☝
1:4 because both numbers can be divided by 64.
Answer:
Oh im sorry!!!! but free points are free points
Step-by-step explanation:
Let's call the younger student's age A and the older student's age B. The teacher's age will be T.
B = 2A
T = 5B
T+5 = 5(A+5)
Simplify the last equation.
T+5 = 5A+25
T = 5A+20
Now we have two equations solved for T, so we can set them equal to each other.
5B = 5A + 20
We can plug 2A in for B
5(2A) = 5A + 20
10A = 5A + 20
5A = 20
A = 4
To find T, we plug 4 in for A in T = 5A + 20
T = 5(4) + 20
T = 40
The answer is 40 years old.
