Answer:

224/100 = 2 24/100

= 2 6/25

308/100 = 3 8/100

= 3 2/25

125/1000 = ⅛

444/1000 = 111/250

Answer:

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

⇒ 0.01 mol/L

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

⇒ 0.000001 mol/L

How many more H+ ions are there in a solution at a

pH = 2 than in a solution at a pH = 6?

⇒ 10,000

Step-by-step explanation:

Answer:

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

0.01

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

0.000001

How many more H+ ions are there in a solution at a

pH = 2 than in a solution at a pH = 6?

10,000

Answer:

l = (x+7) units

Step-by-step explanation:

Given that,

Breadth of the rectangle, b = (x+7) units

Area of the rectangle, [tex]A=x^2+14x+49[/tex]

The area of a rectangle is given by :

[tex]A=lb\\\\l=\dfrac{A}{b}\\\\l=\dfrac{(x^2+14x+49)}{(x+7)}\\\\l=\dfrac{(x+7)^2}{(x+7)}\\\\l=(x+7)\ \text{units}[/tex]

So, the length of the land is (x+7) units.

Answer:

zero

Step-by-step explanation:

The computation of the remainder when the number would be divided by 35

Let the number be x

So if x is divided by 5 gives the remainder 0

x = 0

And, if x is divided by 7 gives the remainder 0

x = 0

So if x is divided by 35 so the remainder is also zero

Answer:

Slope intercept form is y = mx + b

m is slope

b is y intercept

y = -4/5x + -9

I only know that first one sry

Step-by-step explanation:

Answer:

yes.

Step-by-step explanation:

slope intercept form is y=mx+b

b is the y intercept, m is the slope, and x is x.

for

1. it would be

y= -4/5x -9

2. You take the points and do (y2-y1) DIVIDED BY (x2-x1)

it would look like:

(5- -3) / (3-0) = (8/3)

Then plug in one of the sets of numbers for x and y, to get y intercept.

5=8/3(3)+b

b=-3

So.. slope intercept would be y=8/3x -3

Answer:

58 markers

Step-by-step explanation:

52 + 6 = 58

Answer:

58 markers

Step-by-step explanation:

x-6=52 Set up the problem. "x" represents the number of markers.

 +6 +6 Add 6 to both sides to isolate x

x    =58

Answer:

251.33

Step-by-step explanation:

Answer:

251.2 cm square

Step-by-step explanation:

Diameter = 8 cm

Height = 5 cm

8 / 2 = 4

Radius = 4 cm

r^2 * Pi

4 * 4 = 16

16 * Pi = 50.2654824574

16 x 3.14 = 50.24

Base x Height

50.2654824574 x 5 = 251.327412287

50.24 x 5 = 251.2 cm square

Answer:

take side as a

volume of cube=a×a×a

= 13×13×13

(im so sorry if im wrong)

Answer:

x = 12

Step-by-step explanation:

[tex](4x - 5) \degree +(3x + 11) \degree = 90\degree \\(complementary \: \angle s) \\ \\ (4x - 5 + 3x + 11)\degree = 90\degree \\ \\ (7x + 6)\degree = 90\degree \\ \\ 7x + 6 = 90 \\ \\ 7x = 90 - 6 \\ 7x = 84 \\ \\ x = \frac{84}{7} \\ \\ x = 12[/tex]

Answer:

  about 106.5 units

Step-by-step explanation:

The length of each side is found using the distance formula:

  d = √((x2-x1)^2 +(y2-y1)^2)

For example, the length of side AB is ...

  d = √((9 -2)^2 +(1 -3)^2) = √(7^2 +(-2)^2) = √53 ≈ 7.28

The other side lengths are calculated the same way. The sum of side lengths of the given triangle is ...

  AB +BC +CA = 7.28 +13.34 +14.87 = 35.49

__

Multiplying each coordinate by 3 effectively dilates the triangle by a factor of 3 about the origin. That increases the perimeter by a factor of 3, so it is ...

  3(35.49) ≈ 106.5 . . . . units

I find it convenient to use a calculator or spreadsheet to do the tedious calculations.

Answer:

area = m²/2π

Step-by-step explanation:

∵ circumference of circle = 2πr = m

∴ r = m/2π

∵ area of circle = πr²

∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

Answer:

1 ÷ 2 pounds

Step-by-step explanation:

The computation is shown below:

As we know that

1 pound = 0.454 Kg

Peanut starting weight = 3 ÷ 4 of a pound.

In the case when  the bag is 2/3 full, so the weight is  

= 2 ÷ 3 × 3 ÷ 4

= 1 ÷ 2 pounds

Answer: a= 144. b= 67

Step-by-step explanation:

Angle b and the angle of measure 113 are same side interior angles which sum to 180 (When 2 parallel lines are cut by a transversal, special angles are formed)

113+b=180. Subtract 113 from both sides.

b= 67 degrees

Now that you have b, the interior angles of four sided figures sum to 360.

a+113+67+36=360. Combine like terms.

a+216=360. Subtract 216 from both sides.

a= 144 degrees

10 percent of 300 is 30
