Answer:
Step-by-step explanation:
Solve the given equation for y: 6y = 4x + 24. Thus, y = (2/3)x + 4.
This has a y-intercept of 4 and a slope of +2/3. So we can immediately eliminate the middle two graphs.
The correct graph is the first one. We know it's correct because the y intercept is + (whereas it's - in the other alternative answer choice).

Price per inch has the units of "price/inch". See that ? It comes from dividing 'price' by 'inches'.
Price = $7.56
Inches = don't know;
... but we know it's 7 feet, and every foot has 12 inches in it
... so there are (7 x 12) = 84 inches of ribbon.
Price per inch = ($7.56) / (84 inches)
Prince per inch = (7.56/84) (dollars/inch)
Now, YOU go ahead and do the division to get the final answer.
It the multiplication property because you are multiplying 2x=20 so then you divide on both sides with 2 and that gives you 10
Answer: the cost of renting one water tank is 706.5
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the given information,
Radius = 5 feet
Height = 3 feet
Therefore,
Volume = 3.14 × 5² × 3 = 235.5 cubic feet.
If the cost is 3 per cubic foot, then the cost of renting one water tank is
235.5 × 3 = 706.5
Ф =5π/6
The reference angle is the smallest angle that the terminal side of the angle makes with the x-axis.
Given that here π/2 < Ф < π, the angle is in the second quadrant.
In the second quadrant the signs are:
sine positive
cosine negative
tangent negative.
Furthermore, the reference angle is π - Ф = π - 5π/6 = π/6.
Then,
sin Ф = sin π/6 = 1/2
cos Ф = - cos π/6 = -√(3) / 2
tan Ф = - tan π/6 = -√(3) /3
