Answer:

19200 square feet

Step-by-step explanation:

2x+2y=560.  x+y=280

find xy.

(x+y)^{2} =x^{2} +2xy+y^{2}

280^{2} =200^2+2xy

2xy=280^2-200^2

2xy=78400-40000=38400

xy=19200 square feet

There intersecting lines

Step-by-step explanation:

5x+2y=-8

-5x            -5x

2y=-8 -5x

/2   /2  /2

y=-4 -5/2x also

y=-5/2x - 4

Solve the formula V = pi r2h for r
Andrei [34K]

Answer:

V=\pi \times r^{2}\times h\\\\\Longrightarrow V=r^{2}\times \left( \pi \times h\right)  \\\\\Longrightarrow r^{2}=\frac{V}{\pi \times h} \\\\\Longrightarrow r=\sqrt{\frac{V}{\pi \times h} }

HELP!!! <br><br> Which function shows a fabric with a price of $1.25 per square yard?
ohaa [14]

Answer:

y=1.25x

Step-by-step explanation:

Let us assume that,

x represents the number of sq. yards of fabric and

y represents price of the fabric.

As the unit price of the fabric i.e cost per sq. yard of fabric is $1.25, so for each number of sq. yard of fabric, the cost for that much of fabric will be multiple of 1.25 of that number.

i.e y=1.25x

Here, the rate of change is 1.25. So for each increase in x, the amount of increase in y is 1.25

The table along with the graph have been attached below.

A drum of oil has a height of 4 ft and a radius of 1.2 ft. The oil cost $22 per ft³.
iogann1982 [59]
Volume of a Cylinder (Drum) = πr²h

Substitute the known values, 
v = 3.14 * (1.2)² * 4
v = 18.09 Ft³

Now, price for 1 Ft³ = $22
So, for 18.09 Ft³ would be: 22 * 18.09 = $397.9

In short, Your Answer would be: $397.9

Hope this helps!
