H+ ions increase in concentration at lower pH values. Calculate how many more H+ ions there are in a solution at a pH = 2 than in a solution at a pH = 6. Find the concentration of H+ ions at a pH = 2 and at a pH = 6 in Table B. Then divide the concentration of H+ ions at a
pH = 2 by the of H+ ions at a pH = 6. Record your answer in Table C.

What is the concentration of H+ ions at a pH = 2?

mol/L

What is the concentration of H+ ions at a pH = 6?

mol/L

How many more H+ ions are there in a solution at a
pH = 2 than in a solution at a pH = 6?

Answer:

44 is 4/5 out of 55 (44/55 = 4/5)

Step-by-step explanation:

55 can be divided into fifths.

1/5 = 11 or 11/55

11 x 4 = 44

Answer:

2=41     1=49      3=49

Step-by-step explanation:

Angle 2 = 41 because it is directly across the given angle.

Angles 1 and 3 are equal, and the total number of degrees in the rombus are 180.

41+41=82

180-82=98

98 / 2 = 49

Angles and 3 both equal 49

Answer:

2=41°(Alternate Interior angles)

1=41°(diagonal of rhombus bisects the interior angles)

3=49°(180-82/2)

The triangle is doubled

Answer:

the first one is 240

the second one is 280

the third one is 200

The answers that would be discarded would be 220, 360 and 500

Step-by-step explanation:

Hey There!

So for this problem all we have to do is plug in the hours worked and drones sold into the expression 10h+40d

For the first one we just plug in 8 for hours (because he worked 8 hours) and 4 for drones ( because he sold 4 drones )

so we would have 10(8) + 40(4)

10x8=80

40x4=160

160+80=240 So 240 would go with the first one

For the second one we plug in 4 for hours ( because he worked 4 hours) and 6 for drones ( because he sold 6 drones)

so we would have 10(4)+40(6)

10x4=40

40x6=240

240+40=280

So 280 would go with the second one

For the third one we plug in 12 for hours ( because he worked 12 hours) and 2 for drones ( because he sold 2 drones)

so we would have

12(10)+2(40)

12x10=120

2x40=80

120+80=200

so 200 would go with the third one

hope this helps :)

Answer:

EF = 36

Step-by-step explanation:

On a rhombus, all sides are equal because its a parallelogram so,

EF = FG

we first have to find what x equals so . . .

let's plug in the numbers

4x - 20 = 2x + 8

Now we combine like terms

we add 20 to both sides

so now it would be

4x = 2x +28

Now we subtract 2x from both sides because we want x by itself

this would equal

2x = 28

now we divide two from both sides this equals

x = 14

now we insert the numbers in the equation

4 x 14 - 20 = 36

The requried range of the radio station is given as 1256 square miles.

The area of the circle is given by the pie times square of the radius.
A = πr², where r is the radius of the circle.

Here,
A small radio station can broadcast in a circular range with a radius of 20 miles.
The range is given by the area of the circle with given radius,
Area of the circle = πr²
Area of the circle = 3.14 × 20²
area of the circle = 1256 square miles

Thus, the requried range of the radio station is given as 1256 square miles.

Answer:

the total minutes taken together is 26.25 minutes

Step-by-step explanation:

The computation of the number of minutes that required to fill the tank together is shown below:

[tex]\frac{1}{45} + \frac{1}{63} = \frac{1}{x}\\\\\frac{7 + 5 }{315} = \frac{1}{x} \\\\\frac{12}{315} = \frac{1}{x} \\\\12x = 315\\x = 26.25[/tex]minutes

Hence, the total minutes taken together is 26.25 minutes

Answer:

x-121

Step-by-step explanation:

Answer:

x² - 22x + 121

Step-by-step explanation:

(x-11)² is the same as (x-11)(x-11)

multiply the x in the first parentheses by x and -11 in the other parentheses and multiply the -11 in the first parentheses by x and -11 in the other parentheses and add all together

x²- 11x - 11x + 121

x² - 22x + 121
