Answer:
230.55/8.70 = 26.5 hours (round as appropriate)
Answer:
F
Step-by-step explanation:
4.85-4.15=0.7 divided by 2 = 0.35+4.15=4.5*25 cause 30-20=10 divided by 2=5+20=25*4.5=112. closest to that is 120
4x - 6y = -26
-2x + 3y = 13 Multiply this by 2:-
-4x + 6y = 26 Add the first equation to this one. We get:-
0 + 0 = 0
Both equations graph is the same lien.
Infinite number of solutions
The values of (x,y) are when x is 0 then you are 18 on the y axis.
We have given that,
(0, 18)
We have to determine whether the ordered pair could be the missing values represented by (x, y).
<h3>
What is the ordered pair?</h3>
An ordered pair is a pair of objects.
The order in which the objects appear in the pair is significant
The ordered pair is different from the ordered pair unless a = b.
Ordered pairs are also called 2-tuples, or sequences of length 2.
Therefore, The values of (x,y) are when x is 0 then you are 18 on the y axis.

Arctan (√3 /3) = 30°. = π/6 rad
That is the value searched, in degrees and radians.
You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3
