Answer:

volume of empty space = 141.3 cm³

Step-by-step explanation:

volume of empty space = volume of the cylinder - volume of water

First, we need to calculate the volume of the container

volume of a cylinder = πr²h

 where r = radius of the container   and   h is the height of the container

r = 3cm  and h = 12 cm    π is a constant which is ≈ 3.14

volume of a cylinder = πr²h

                                  =3.14 × 3²×12

                                   =3.14×9×12

                                    =339.12 cm³

We will proceed to find the volume of water

since liquid will take the shape of its container,

then volume of water =  πr²h

r is the radius of the container   and    h is the height of the water

r = 3cm    and   h = 7cm      

volume of water =  πr²h

                             = 3.14 ×3²×7

                              =3.14×9×7

                              =197.82 cm³

volume of empty space = volume of the cylinder - volume of water

                                          =339.12 cm³    -    197.82 cm³

                                          = 141.3 cm³

OR

WE CAN SOLVE DIRECTLY

height of empty space = height of container - height of water

                                       = 12 - 7

                                        =5 cm

volume of empty space = πr²h

                                        =3.14×3²×5

                                        =3.14×9×5

                                         =141.3 cm³

volume of empty space = 141.3 cm³

The volume of the empty space in the cylinder is equal to the difference between the volume of the cylinder and the volume of water in the cylinder.

The volume of the cylinder can be calculated using the formula:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

Substituting the given values, we get:

V = π(3 cm)^2(12 cm)

V ≈ 339.3 cubic centimeters

The volume of water in the cylinder can be calculated by multiplying the cross-sectional area of the cylinder by the height of the water:

V_water = πr^2h_water

where V_water is the volume of water and h_water is the height of the water.

Substituting the given values, we get:

V_water = π(3 cm)^2(7 cm)

V_water ≈ 197.9 cubic centimeters

Therefore, the volume of empty space in the cylinder is:

V_empty = V - V_water

V_empty ≈ 339.3 - 197.9

V_empty ≈ 141.4 cubic centimeters

So, the volume of empty space in the cylinder is approximately 141.4 cubic centimeters.

Answer:

Step-by-step explanation:

I won't do all these but you should get the idea of how to do them from the following. Be careful with the units if they are given . You must convert both values to the same unit before working out the percentages.

a. What proportion of 15 is 5:

As a fraction it is 5/15 = 1/3.

Now convert to a percentage by multiplying by 100:

1/3 * 100 = 33.33%

b.  20 and 10

= 10/20 = 1/2

1/2 * 100 = 50%.

e.  £30  and £12

= 12/30

= 2/5

= 2/5 * 100 = 40%.

h. 6.4 is 0.4

= 0.4 / 6.4

= 4/64

= 1/16

= 1/16 * 100 = 6.25%

i. £144 is 12p

Here we convert the 2 values to pence:

£144 = 144 * 100 = 14,400p

The fraction is 12/14,400

= 1/1200

= 1/1200  * 100 = 0.083%

j. 1.2 m is 30 cm

Convert 1.2 m to cm

= 1.2 * 100 = 120

The fraction is 30/120 = 1/4

= 1/4  100 = 25%.

Answer:

The graph with a y-intersect of (0, -3) and x-intercept of (12, 0)

Step-by-step explanation:

So the graph goes 1 unit up every 4 units to the right

The graph which represents the linear function y = 1/4x – 3 is A. A line on a graph passes through the (-4, -4), (0, -3), and (4, -2).

A linear function can be defined as the function whose graph is a straight line. It can also be defined as the function with one or more variables and the exponent of the variable is 1.

Given linear function is,

y = 1/4x – 3

Substitute x = 0.

y = 0 - 3 = -3

So the graph passes through (0, -3).

Let x = 4.

y = (1/4 × 4) - 3 = -2

So the graph passes through (4, -2).

Let x  = -4,

y = (1/4 × -4) - 3 = -4

So the graph passes through (-4, -4).

Hence the graph passes through (-4, -4), (0, -3), and (4, -2).

Answer:

90%

Step-by-step explanation:

So, in order to get this answer, you must divide the amount of students that filled the theatre, which is 4,500, by the amount of seats at the theatre, which is 5,000. You can eliminate the two zeros at the end of each number, which will leave you with 45/50. 45 divided by 50 equals 0.9. You can then multiply 0.9 by 100, because of the 2 zeros eliminated earlier. This will leave you with 90%.

Answer: The probability is 1/190 = 0.005

Step-by-step explanation:

The probability of ordering two specific toppings out of 20 is:

For the first selection he can order 2 of them, peperoni or sausage, so the probability for the first selection is 2/20 = 1/10 (the number of correct options divided by the total number of options)

For the second selection we have only one option, because we assume that the other one was selected previously, here we also had a total of 19 toppings because one already was selected, the probability in this selection is 1/19.

The joint probability is equal to the product of those two probabilities:

P = (1/19)*(1/10) = 1/190 = 0.005

Answer:

p = 23       and p = -22

Step-by-step explanation:

| 2p -1 | =45

Absolute value equations have 2 solutions, one positive value and one negative

2p-1 = 45    and 2p-1 = -45

Add 1 to all sides

2p-1+1 = 45+1    and 2p-1+1 = -45+1

2p = 46                        2p = -44

Divide by 2

2p/2 = 46/2    and   2p/2  = -44/2

p = 23       and p = -22

Answer:

Step-by-step explanation:

Considering a person peak blood is 0.07

It decrease by 4% every hour

a) Using exponential function

[tex]f(x) = Ca^x[/tex]

where,

a = 1 + r

r = -0.40%

Here,

C = 0.07,

a = 1 - 0.04 = 0.06

[tex]f(x)=0.07(0.6)^x[/tex]

b)

Here the hourly decay factor is 0.6

[tex]B(x)=ca^x\\\\0.07(0.6)^x[/tex]

c) Evaluate

[tex]B(2)=0.07\times (0.6)^2\\\\0.07(0.36)\\\\= 0.0252g[/tex]

0.0252g or 100mL

Answer:

a) Hourly decay factor = 0.6

b) [tex]B(x) = 0.07(0.6)^x[/tex]

c) B(2) = 0.0252

This result means that the blood alcohol level will be 0.0252 (grams per 100 ml) after 2 hours

Step-by-step explanation:

Since the function is an exponential function, it can be modeled as:

[tex]B(x) = C (1 + r)^x[/tex]

Where the peak blood alcohol level, C = 0.07

Since the blood level decreases by 40%(0.4) every hour, r = -0.4

The hourly decay factor is given by a = 1 + r

a = 1 + (-0.4) = 1 - 0.4

a = 0.6

Therefore, the hourly decay factor = 0.6

b) The exponential function is:

[tex]B(x) = Ca^x[/tex]

Where a = 1 + r = 0.6

C = 0.07

[tex]B(x) = 0.07(0.6)^x[/tex]

c) Evaluate B(2)

Substitute x = 2 into the exponential function gotten in part (b)

[tex]B(2) = 0.07(0.6)^2\\B(2) = 0.0252[/tex]

This result means that the blood alcohol level will be 0.0252 (grams per 100 ml) after 2 hours

Complete Question:

A sundae requires 2 ice-cream scoops and 4 raspberries, and a milkshake requires 3 ice-cream scoops and 5 raspberries. Laila wants to sell sundaes and milkshakes with at most 80 ice-cream scoops and 150 raspberries. Let S denote the number of sundaes she makes and M the number of milkshakes she makes. Write an inequality that represents the condition based on the number of (ICE-CREAM SCOOPS).

Answer:

An inequality that represents the condition based on the number of (ICE-CREAM SCOOPS) is given as:

2S + 3M ≤ 80

Step-by-step explanation:

From the above question, we are told that:

Let S denote the number of sundaes Laila makes

M the number of milkshakes

a) A sundae requires 2 ice-cream scoops and 4 raspberries

A sundae = 2S and 4S

b) A milkshake requires 3 ice-cream scoops and 5 raspberries.

A milk shake = 3M and 5M

Laila wants to sell sundaes and milkshakes with at most 80 ice-cream scoops and 150 raspberries .

Therefore, an inequality that represents the condition based on the number of (ICE-CREAM SCOOPS) is given as:

2 ice cream scoops + 3 ice cream scoops ≤ 80

2S + 3M ≤ 80

Answer:

a) min = 4.4251

b) max = 8.5743

Step-by-step explanation:

Given:

Mean, u = 6.5

Standard deviation = 1

To get our values, we are to use the inverse of the standard normal table.

a) The minimum head breadth that will fit.

P(Z < z) = 1.9%

P(Z < z) = 0.019

P(Z < -2.0749) = 0.019

z = -2.0749

From the z-score formula, we have:

[tex] \frac{x - \mu}{\sigma} = Z_0_._0_1_9 [/tex]

Let x be the breath of heads.

Making x the subject of the formula, we have:

[tex] x = z * \sigma + \mu [/tex]

We already have:

z = -2.0749

u = 6.5

s.d = 1

Substituting figures, we have:

x = (-2.0749 * 1) + 6.5

x = 4.4251

The minimum head breadth that will fit the clientele is 4.4251

b) The maximum head breadth that will fit.

P(Z > z) = 1.9%

1 - P(Z < z) = 0.019

P(Z < z) = 1 - 0.019 = 0.981

P(Z < 2.0749) = 0.981

From the z-score formula, we have:

[tex] \frac{x - \mu}{\sigma} = Z_0_._0_1_9 [/tex]

Let x be the breath of heads.

Making x the subject of the formula, we have:

[tex] x = z * \sigma + \mu [/tex]

We already have:

z = 2.0749

u = 6.5

s.d = 1

Substituting figures, we have:

x = (2.0749 * 1) + 6.5

x = 4.4251

x = 8.5743

The maximum head breadth that will fit the clientele is 8.5743
