Answer:

10,080,000 cubic meters is the answer.

Step-by-step explanation:

For every minute (x), 168,000 cubic meters (y) of water are added. 1 hour has 60 minutes, so 60 x 168,000. That gives 10,080,000.

450 cm^{3} ⇒ m^{3}

1 cm^{3} = 0.000001 m^{3}

= 450 cm^{3} = 450 × 0.000001 = 0.00045 m^{3}

Find the slope of the line going through the points (0,6) and (-3,9)
andre [41]

Answer:

The slope of the line is 5.

The point slope form of the line is y=5x+6.

Step-by-step explanation:

We can find the slope using this formula: \frac{y_{2} }{x_{2} } -\frac{y_{1} }{x_{1} }

\frac{6}{0} -\frac{9}{-3} =

\frac{6}{0} -(-\frac{9}{3} )=

\frac{6}{0} +\frac{9}{3} =

\frac{15}{3} =

5

The slope of the line is 5.

To find point slope form, we use the equation y=mx+b where m is the slope and b is the y-intercept.

The y-intercept of this slope is 6 and the slope is 5 so we get, y=5x+6

I need help!! I don’t know which one it is.<br> Which point is closest to point A?<br> Point__
aleksandrvk [35]

Answer:

Point D

Step-by-step explanation:

The length from Point A to Point D is 6 units, while the length from point A to Point C is 7 units, and the length from Point A to Point B is also 7 units. Because to reach Point C, you have to make one turn, adding one more unit. Same with Point B.

Find the slope of the line that passses thruogh 1,5 and 10,9
vichka [17]

Answer:  The slope is 4/9  or -4/-9.

Step-by-step explanation:

(1,5)  

(10,9)   Find the difference in the y values and divide it by the difference in the x values.

5-9= -4

1- 10= -9

-4/-9= 4/9

so the slope is 4/9  

Using the slope we could also find the y-intercept and write the equation.

5=4/9 (1) + b    where b is the y-intercept

  5= 4/9 + b

-4/9   -4/9

b= 41/9  

Now we will have the equation  y= 4/9 + 41/9
