(both to the nearest tenth).

Step-by-step explanation:

Area of the surface of the river = area of the outer circle - area of the inner circle.

Radius of the outer circle = 30 *3 = 90 feet.

So the surface area of the river = π(90)^2 - π(85)^2

= 875π ft^2

Also the volume of the river = surface area * depth = 875π*4 = 3500π ft^3

= 10,995.6 ft^3.

Number of gallons of water it will hold = 10,995.6 / 4.78

= 2300.3 gallons.

Write the equation of a line in standard form that has x-intercept (P,0) and y-intercept (0,R).

ExtremeBDS [4]

Answer:

$Rx+Py=RP$

Step-by-step explanation:

The points on the straight line are (P, 0) and (0, R).

The slope would be

$m=\frac{R-0}{0-P}=-\frac{R}{P}$

And $b=R$ , because the y-intercept is at (0, R).

So, the equation of this line would be

$y=-\frac{R}{P} x+R$

Where we multiply the equation by $P$

$Py=-Rx+RP$

Therefore, the equation that represents this line is

$Rx+Py=RP$

<h2>So, the right answer is B.</h2>

The possible values of x are given by x+8=<6.<br><br>The greatest possible value of 7x is_____

kozerog [31]

Answer:

The possible values of x is given by $x\leq -2$ and they include: -2, -3, -4, -5, -6 and so on

The greatest possible value of 7x is $-14$

Step-by-step explanation:

We are given the equation: x + 8 <= 6

Let collect the like terms:

$x + 8 \leq 6\\x\leq 6 -8\\x \leq -2$

Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on

To find the greatest possible value of 7x is when x = -2.

$7x = 7 * -2\\7x = -14\\$ .
