Answer:

3,493 digits

Step-by-step explanation:

Total pages of the book = 1,150

Page 1 - 9 = 9 digits

Page 10 - 99

= 2 * 90 pages

= 180 digits

Page 100 - 999

= 3 × 900 pages

= 2,700 digits

Page 1000 - 1,150

= 4 × 151 pages

= 604 digits

Total digits required in numbering 1,150 pages = 9 + 180 + 2,700 + 604

= 3,493 digits

Total digits required in numbering 1,150 pages = 3,493 digits

[tex](l,w) = (9,9)[/tex]

Step-by-step explanation:

Given

[tex]P = 36ft[/tex] --- perimeter

[tex]l \to length[/tex]

[tex]w \to width[/tex]

Required

Possible dimension of different parallelogram

The perimeter is calculated as:

[tex]P=2(l+w)\\\\\\[/tex]

So,we have:

[tex]2(l+w)=36[/tex]

Divide by 2

[tex]l + w = 18[/tex]

Since l and w must be positive integers, the possible dimensions are:

[tex](l,w) = (1,17)[/tex]

[tex](l,w) = (2,16)[/tex]

[tex](l,w) = (3,15)[/tex]

---

-

[tex](l,w) = (9,9)[/tex]

The question is incomplete. The complete question is :

The pH of a solution is a measure of the quantity of hydrogen atoms (H) in the solution. It is given by the formula f(x) = −log x. In the formula, x = [H+], the molar concentration of hydrogen atoms, or the number of moles of hydrogen atoms per liter of solution

The approximate molar concentration of several chemicals are given. Find the pH of each. Use the calculator and round to the nearest tenth, if necessary.

Oven cleaner: [H+] = 10−13 pH =

Water: [H+] = 0.0000007 pH =

Blood: [H+] = 0.00000004 pH =

Vinegar: [H+] = 0.0063 pH =

Solution :

Given formula :

f(x) = −log x

Here,  x = [H+] = molar concentration of hydrogen atoms

Therefore, the pH of each of the following solution are :

Oven cleaner

[[tex]$H^+$[/tex]] = [tex]$10^{-13}$[/tex]

pH = - log [[tex]$H^+$[/tex]]

     = [tex]$- \log 10^{-13}$[/tex]

     = 13

Water

[[tex]$H^+$[/tex]] = 0.0000007

pH = - log [[tex]$H^+$[/tex]]

     = - log 0.0000007

     = 6.2

Blood

[[tex]$H^+$[/tex]] = 0.00000004

pH = - log [[tex]$H^+$[/tex]]

     = - log 0.00000004

     = 7.4

Vinegar

[[tex]$H^+$[/tex]] = 0.0063

pH = - log [[tex]$H^+$[/tex]]

    = - log  0.0063

    = 2.2

Answer:

Sam is incorrect.

Step-by-step explanation:

Using Pythagorean Theorem, we can find the length of diagonal SQ as 13.4 (6^2 + 12^2 = c^2, 36 + 144 = c^2, sqrt(180) = c, c is approx 13.4). We can do the same for diagonal OM (6^2 + 6^2 = c^2, 36 + 36 = c^2, 72 = c^2, sqrt(72) = c, c is approx 8.5). Sam is therefore incorrect because 13.4 is not double of 8.5.

Answer:

Sam is incorrect.

Step-by-step explanation:

Sam is incorrect. By using the Pythagorean theorem, we can find out what each diagonal is equal to.

Starting with diagonal SQ...

6^2 + 12^2 

= 36 + 144

= 180

Square root of 180?

= 13.41

Diagonal OM...

6^2 + 6^2 

= 36 + 36

=  72

Square root of 72?

 = 8.48

Therefore, Sam is incorrect because 8.4 isn't half of 13.4.

Answer:

the rules regarding the vertex of a quadratic function are:

the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph.

Answer:

m = w - t

£108

Step-by-step explanation:

m = Money Billy has to spend per week :

m = wage, w - tax, t

Hence,

m = w - t

Given;

Wage = £150 ; tax = £42

m = £150 - £42

m = £108

Answer:

kojo = x + 15

kofi = $182.50

kojo = $197.50

Step-by-step explanation:

kofi = x  

kojo = x + 15 (since Kojo h as 15 cedis more than Kofi)

380= x + 15 + x

2x + 15 = 380

combine like terms

2x = 380 - 15

2x = 365

x = 182.50

Kojo = 15 + 182.50 = $197.50

Answer:

[tex]m\angle RTS=34^{\circ}[/tex]

Step-by-step explanation:

From the Isosceles Base Theorem, the two base angles of an Isosceles Triangle are equal. Therefore, [tex]m\angle RTS=m\angle TRS[/tex].

Since the sum of the interior angles of a triangle is 180 degrees, we have:

[tex]m\angle RTS +m\angle TRS+112=180,\\2\cdot m\angle RTS+112=180,\\2\cdot m\angle RTS=68,\\m\angle RTS=\boxed{34^{\circ}}[/tex]

Answer:

The only possible answer that is correct is the first one, x = -4.

Step-by-step explanation:

Simplify the given inequality as much as possible, and then substitute each of the given x values one by one to determine which is in the solution set.

9(2x + 1) < 9x - 18 becomes 18x + 9 < 9x - 18, which, if reduced by dividing all four terms by 9, becomes 2x + 1 < x - 2.

Simplifying further, we get x < - 3.  The only possible answer that is correct is the first one, x = -4.  -4 < -3 is true.

Answer:

It is 44

Step-by-step explanation:

The perimeter of the paralllelogram given is: 44 units.

Perimeter = 2(a + b), where a and b are the legs of the sides adjacent to each other.

Given the following:

Since opposite sides of a parallelogram are equal, therefore:

4y - 2 = 2y + 6

4y - 2y = 2 + 6

2y = 8

y = 4

2x + 2 = 3x - 1

2x - 3x = -2 - 1

-x = -3

x = 3

Perimeter of the paralllelogram = 2(AB + AD) = 2(4y - 2 + 3x - 1)

Plug in the values of x and y

Perimeter of the paralllelogram = 2(4(4) - 2 + 3(3) - 1)

Perimeter of the paralllelogram = 2(16 - 2 + 9 - 1)

Perimeter of the paralllelogram = 44 units.

Answer:

Option (2)

Step-by-step explanation:

All angles are positive when measured counterclockwise from the x-axis.

Terminal side of 240° degrees when measures counterclockwise will lie in the 3rd quadrant.

But the angle is -240°.

That means angle is being measured clockwise from the x-axis.

Therefore, terminal side of the of the angle will be in the 2nd quadrant.

Option (2) will be the correct option.

Answer:

Step-by-step explanation:

To find the area of this figure, we must first find the areas of the shapes that compose this figure.

This figure is made up of a rectangle and a semicircle.

Remember: To find the area of a semicircle, multiply the radius by itself twice, then multiply the product pi, lastly divide the product by 2.

[tex]a=\pi r^2/2[/tex]

3.14 will be used for pi!

To find the area of a rectangle, multiply the length by the width. The product is the area of the rectangle.

[tex]a=lw[/tex]

Now, let's solve.

The diameter of the semicircle is 32 centimeters.

To find the radius of a semicircle, divide the diameter by 2.

[tex]32/2=16[/tex]

The radius of the semicircle is 16 centimeters.

Now that we have the radius, we can find the area of the semicircle.

[tex]\pi 16^2/2=401.92[/tex]

The area of the semicircle is 401.92 centimeters.

Furthermore, we find the area of the rectangle.

[tex]14*32=448.[/tex]

The area of the circle is 448 centimeters.

Next, we add the areas of both shapes to find the area of this figure.

[tex]401.92+448[/tex]

[tex]=849.92[/tex]

The final step is to round 849.92 to the nearest tenth.

Even though 849.92 to rounded to the nearest tenth is 849.9, there is no answer choice for this. The closest one to this answer is choice 'b.'

I, therefore, believe the area of this figure is 850.1 centimeters.

Answer:

167.6 minutes

Step-by-step explanation:

The formula is given as:

P(t) = Po × (2)^t/k

Where

P(t) = Population after time t = 100000

Po = Initial population = 300

k = Doubling time = 20 minutes

t = Time = ?

Hence:

100000 = 300 × (2)^t/20

Divide both sides by 300

100000/300 = (300 × (2)^t/20)/300

333.3 = 2^t/20

Take the In of both sides

In 333.3 = In (2^t/20)

In 333.3 = t/20 In 2

Divide both sides by In 2

In 333.3/In 2 =( t/20 In 2)/In 2

8.3806775072 = t/20

Cross Multiply

t = 8.3806775072 × 20

t = 167.61355014 minutes

Approximately = 167.6 minutes

Therefore, the time it will take to reach an unsafe level of 100000 bacteria is 167.6 minutes
