Answer:

[tex]267.95 cm^3[/tex]

Step-by-step explanation:

We need to first find the radius of the sphere.

The surface area of a sphere is given as:

[tex]A = 4\pi r^2[/tex]

where r is the radius

Therefore:

[tex]200.96 = 4 * 3.14 * r^2\\\\=> r^2 = 200.96 / 12.56\\\\r^2 = 16\\\\r = \sqrt{16} \\\\r = 4cm[/tex]

The radius of the sphere is 4 cm.

The volume of a sphere is given as:

[tex]V = \frac{4}{3} \pi r^3[/tex]

Therefore, the volume of the sphere of radius 4 cm is;

[tex]V = \frac{4}{3} * 3.14 * 4^3\\\\V = 267.95 cm^3[/tex]

The volume of the sphere is [tex]267.95 cm^3[/tex]

Answer:

€ 231.88

Step-by-step explanation:

The total amount Tu's family paid for the 10 nights without the coupon = 200 × 10 = € 2000

With a Tu's mum's coupon of 6.5 % off the total room charges, the amount off = 6.5/100 × 2000 = € 130

The total amount Tu's family paid for the 10 nights with the coupon = € 2000 - € 130 = € 1870

The total room tax = 12.4 % × € 1870 = € 231.88

[tex]4x^2-25[/tex] is a difference of squares with a factor 2x+5

because when we factorize [tex]4x^2-25[/tex] we get [tex](2x-5)(2x+5)[/tex]

The expression is a difference of squares with a factor of 2x + 5 [tex]$4 x^{2}-25$[/tex].

Given:

2x + 5

To find:

The expression is a difference of squares with a factor of 2x + 5.

Step 1

The difference of squares formula is given by

[tex]$(a+b)(a-b)=a^{2}-b^{2}$$[/tex]

We have been given that one factor is 2x + 5.

Hence, [tex]$\mathbf{a}=\mathbf{2 x}, \mathbf{b}=\mathbf{5}$[/tex]

Step 2

It means that the other factor must be (a - b) = (2x - 5)

Hence, in order to expression, we can multiply the factors.

(2x + 5)(2x - 5)

Step 3

Using the difference of squares formula

(2x + 5)(2x - 5)

[tex]$&=(2 x)^{2}-5^{2} \\[/tex]

[tex]$&4 x^{2}-25[/tex]

The required expression exists [tex]$4 x^{2}-25$[/tex].

Therefore, the correct answer is [tex]$4 x^{2}-25$[/tex].

Answer:

The floor, in square feet, you need to tile is [tex]27ft^{2}[/tex]

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes.

To solve this problem we need to calculate the areas of the sink and the bathtub and subtract it from the the area of the the bathroom, the result is the amount of space you need to tile

Step one

Area of sink

[tex]area= length * width\\ area= 3* 2 = 6 ft^{2}[/tex]

Area of bathtub

[tex]area= length * width \\area= 5*3\\area= 15ft^{2} \\[/tex]

Area of bathroom

[tex]area= length* width\\ area = 8* 6\\area=48ft^{2}[/tex]

Step two

To calculate the area we need to tile

let us subtract the areas of the bathtub and the sink from the bathroom we have

[tex]= 48-15-6\\=27ft^{2}[/tex]

Answer:

3600 bacterias

Step-by-step explanation:

From P = P'e^(-kt), where

P = final population

P' = initial population

k = decay constant

t = time in hrs

Substituting we have

200 = 170000 x e^(-42k)

1/850 = e^(-42k)

We take natural log (Ln) of both side

Ln (1/850) = Ln (e^(-42k))

-6.745 = -42k

k = 0.16059.

For amount remaining after 24 hrs we find P

P = 170000 x e^(-0.16059x24)

P = 170000 x e^-3.85416

P = 170000 x 0.02119 = 3602.3

Approximately 3600 bacterias.

Step-by-step explanation:

9 x - 10 = 3 x + 2

Subtract 3x from each side

9 x -3x- 10 = 3 x-3x + 2

6x -10 =2

Add 10 to each side

6x-10+10=2+10

6x = 12

Divide each side by 6

6x/6 = 12/6

x = 2

Answer:

x = 2

Step-by-step explanation:

9x - 10 = 3x + 2

9x - 3x = 2 + 10

Answer:

Circumference = 2 x 3.14 x radius = 27 (in)

=> radius = 27/(2 x 3.14) = 4.3 (in)

=> Area = 3.14 x radius^2 = 3.14 x 4.3^2 = 58.1 (in2)

Answer:

58 inches^2

Step-by-step explanation:

The formula for the area of a circle is [tex]\pi *radius^{2}[/tex]

To work out the area of this circle you would first need to divide the circumference of 27 by pi, this gives you 8.594. This is because the formula for the circumference is: [tex]\pi *diameter\\[/tex] and so by dividing the circumference by pi we are isolating the value of the diameter.

Then now that we have worked out the diameter we can now begin to work out the area, however in order to work out the area we must work out the radius. You can do this by dividing the diameter by 2, which gives you 4.297.

Then to work out the area you would multiply pi by the radius of 4.297 squared, this gives you 58.01 [tex]inches^{2}[/tex].

The next step is to round it to the nearest whole number, this gives you 58.

1) Divide 27 by pi.

[tex]27/\pi =8.594[/tex]

2) Divide 8.594 by 2.

[tex]8.594/2=4.297[/tex]

3) Multiply pi by 4.297 squared.

[tex]\pi *4.297^{2} =58.01[/tex]

4) Round to the nearest whole number.

Answer:

It will take 1.25 seconds to reach the ground.

Step-by-step explanation:

The equation of the containers pathway can be modeled by the equation given below :

[tex]h=-16t^2+25[/tex]

t is time in seconds

It is required to find the time taken by the container to reach the ground. When it reached ground, its height is equal to 0 such that,

[tex]h=0\\\\-16t^2+25=0[/tex]

[tex]-16t^2=25\\\\t=\sqrt{\dfrac{25}{16}} \\\\t=1.25\ s[/tex]

So, it will take 1.25 seconds to reach the ground.
