<h3>The amount of Chlorine (A) to add to a basin is 112590000000</h3>

<em><u>Solution:</u></em>

Given that,

<em><u>A wastewater treatment operator uses the formula:</u></em>

A = 8.34 \times FC

Where,

A = amount of chlorine to add to basin

The flow through the basin is Fand the concentration of Chlorine to water is C

From given,

F = 1800

C = 7, 500, 000

To find: A

A = 8.34 \times 1800 \times 7500000\\\\A = 15012 \times 7500000\\\\A = 112590000000

Thus amount of Chlorine (A) to add to a basin is 112590000000

In wxy x=y, wx= 9x-11, xy= 4x-1, and wy= 7x-3, find x and the measure of each side
worty [1.4K]

Answer:

WX = WY

9x - 11 = 7x - 3..........Then subtract 7x to the other side such that

2x - 11 = -3..........Then add 11 to both sides such that

2x = 8...........Then divide 2 such that

x = 4

Now we can find each side such that

WX = 9(4)-11 = 25

WY = 7(4)-3 = 25

XY = 4(4)+1 = 17

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ First identify and assign the variables:

q = number of quarters

d = number of dimes

This is what we know:

q + d = 22

A quarter is 25 cents and a dime is 10 cents

You can write this as:

0.25q + 0.1d = 3.40

Rearrange the first equation for d

d = 22 - q

Substitute this value into the other equation:

0.25q + 0.1(22 - q) = 3.40

Simplify:

0.25q + 2.2 - 0.1q = 3.40

0.15q + 2.2 = 3.4

Subtract 2.2 from both sides:

0.15q = 1.2

Divide both sides by 0.15:

q = 8

Substitute into the first equation:

8 + d = 22

d = 14

Therefore, there are 8 quarters and 14 dimes.

Complete the table to investigate dilations of exponential functions.
Zinaida [17]

Answer:

a = 1

b = 3

c = 1

d = 2

e = 6

f = 8

Step-by-step explanation:

Any integer with power as zero = 1

<h3>For a</h3>

2^x

2^0

= 1

<h3>For b</h3>

3 * 2^x

3 * 2^0

3 * 1

= 3

<h3>For c</h3>

2 ^ 3(x)

2 ^ 3(0)

2 ^ 0

= 1

<h3>For d</h3>

2^1

= 2

<h3>For e</h3>

3 * 2^x

3 * 2^1

3 * 2

= 6

<h3>For f</h3>

2 ^ 3(x)

2 ^ 3(1)

2 ^ 3

2 * 2 * 2

= 8
