Answer:
the answer for 481+7+0.56 is 488.56
9 and 4 is the answer for the 3rd and 4th one
Hello : let A(1;5) and B(-2;14)
the equation is y = ax+b .... a is a slope
a = (yb -ya)/(xb -xa)
a = (14-5)/(-2-1)
a = -3
y = -3x+b
A passes <span>through</span> the line : 5 =-3(1)+b ..... b = 8
y = -3x+8
<em>Note: I am assuming we have to determine the angle 'Ф'.</em>
Answer:
The value of Ф = 22.6°
Step-by-step explanation:
Given
hypotenuse = 13
To determine:
Angle = Ф = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
so substituting adjacent = 12, hypotenuse = 13 in the equation
cos Ф = adjacent / hypotenuse
cos Ф = 12 / 13
Ф = arccos (12/13)
Ф = 22.6°
Therefore, the value of Ф = 22.6°
Oil / gas
5/18 = x / 36....5 oz oil to 18 gal gas = x oz oil to 36 gal gas
cross multiply because this is a proportion
(18)(x) = (36)(5)
18x = 180
x = 180/18
x = 10 <=== so there is 10 oz of oil
