Answer:
5/75 in my opinion. 75 is total of hot drink
Step-by-step explanation:
Is (2,4) a solution for y <= 3x -1 ??
answer : No
x = 2, replace it in the equation
y <= 3(2) - 1
y<= 5
--_(2,5)
y = 4, again replace it in equation
4 <= 3x - 1
3x <= 5
x <= 5/3
--_(5/3,4)
Answer:
Yes.
Step-by-step explanation:
It can be expressed as a ratio and it is a fraction.
Answer:
Option C is correct.
Step-by-step explanation:

We need to find reference angle and signs of sinФ, cosФ and tanФ
We know that
is equal to 150°
and 150° is in 2nd quadrant.
So, Ф is in 2nd quadrant.
And In 2nd quadrant sine is positive, while cos and tan are negative
The reference angle Ф' is found by: π - Ф
=> Ф = 5π/6
so, Reference angle Ф' = π - 5π/6
Ф' = 6π - 5π/6
Ф' = π/6
So, Option C Θ' = pi over 6; sine is positive, cosine and tangent are negative is correct.
