Answer please? ___ feet per second

Oksanka [162]

Answer: 30 feet per second

========================================

x = diameter, y = speed of water

y varies inversely with respect to x, so, y = k/x for some constant k

If x = 0.6 and y = 5 pair up, then y = k/x turns into 5 = k/0.6 which solves to k = 3 when you multiply both sides by 0.6

So the equation y = k/x turns into y = 3/x

Now plug in the diameter x = 0.1 to find the speed to be...

y = 3/x

y = 3/0.1

y = 30 feet per second

Determine the expression you can substitute for x in 4x + 2y= 3

rusak2 [61]

Answer:

−1 /2 y+ 3 /4

Step-by-step explanation:

Let's solve for x.

4x+2y=3

Step 1: Add -2y to both sides.

4x+2y+−2y=3+−2y

4x=−2y+3

Step 2: Divide both sides by 4.

4x /4

−2y+3 /4

−1 /2 y+ 3 /4

ioda

Answer:

strategies used are : identifying a sub-goal and Guess and check

Step-by-step explanation:

To create a 3 by 3 magic square using nine of the ten numbers

20,21,22,22,23,24,25,26,27,28 and 29

In order to achieve a 3 by 3 magic square table we will pick Nine consecutive numbers out of the ten numbers given and apply the format below

n+1,n-4,n+3,n+2,n,n-2,n-3,n+4,n-1

we will take n = 24

attached below is the magic square

Please help out with this worksheet please i would appreciate it

rodikova [14]

Answer:

1. slope: (y2-y1)/(x2-x1)

(6,38), (9,32)

(32-38)/(9-6) = -6/3 = -2

38 = -2(6) + b

38 = -12 +b, b = 50

y = -2x + 50

2a. Slope = -80, the slope means how many cars left per hour after closing. Y- intercept = 600, cars in lot during closing.

2b. use the equation: y = -80x + 600

Plug in 3 into the equation

y = -80(3) + 600, y = -240 + 600, y = 360 cars

2c. For it to have 0 cars, plug in 0 for y

0 = -80x + 600

-600 = -80x, solve for x

x = 7.5 hours
