Answer: 96ft
Step-by-step explanation:
Width times hight equals area. So 12x8=96ft
Hey there!
Line passes through (4, -1) & is parallel to 2x -3y=9
Let's start off by identifying what our slope is. In the slope-intercept form y=mx+b, we know that "m" is our slope.
The given equation needs to be converted into slope-intercept form and we can do this by getting y onto its own side of the equal sign.
Start off by subtracting 2x from both sides.
-3y = -2x + 9
Then, divide both sides by -3.
y = (-2x + 9)/-3
Simplify.
y = 2/3x - 3
"M" is simply a place mat so if we look at our given line, the "m" value is 2/3. Therefore, our slope is 2/3.
We should also note that we're looking for a line that's parallel to the given one. This means that our new line has the same slope as our given line. Therefore, our new line has a slope of 2/3.
Now, we use point-slope form ( y-y₁=m(x-x₁) ) to complete our task of finding a line that passes through (4, -1). Our new slope is 2/3 & it passes through (4, -1).
y-y₁=m(x-x₁)
Let's start by plugging in 2/3 for m (our new slope), 4 for x1 and -1 for y1.
y - (-1) = 2/3(x - 4)
Simplify.
y + 1 = 2/3 + 8/3
Simplify by subtracting 1 from both sides.
y = 2/3x + 8/3 - 1
Simplify.
y = 2/3x + 5/3

Answer:
the cost of filling the pool is $386.3
Step-by-step explanation:
Given;
dimension of the rectangular pool, = 25 yd by 30 yd by 5.1 ft
covert the given dimensions to feet;
1 yd = 3 ft
25 yd = 25 x 3 ft = 75 ft
30 yd = 30 x 3 ft = 90 ft
The volume of the rectangular pool in cubic feet (ft³);
Volume = 75 ft x 90 ft x 5.1 ft
Volume = 34,425 ft³
Convert the volume to gallons;
1 ft³ = 7.481 gallons
10,125 ft³ = 34,425 x 7.481 gallons
= 257,533.425 gallons
The cost per a 1000 gallons is $1.50, then cost of the 257,533.425 gallons is calculated as;
Therefore, the cost of filling the pool is $386.3
