Answer:

x = 14.4

Step-by-step explanation:

Using dilations, the following equation can be written to show the relationship between the two similar triangles:

x/4 = (6.5 + 2.5)/2.5

x/4 = 9/2.5

Cross multiply

x*2.5 = 9*4

2.5x = 36

2.5x/2.5 = 36/2.5

x = 14.4

Step-by-step explanation:

The volume of the rectangular prism is equal to...

L x W x H    (where L is length, W is width, and H is the height)

Therefore we know that the volume of this rectangular prism is...

L x W x H

8cm x 1cm x 5cm = 40[tex]cm^{3\\}[/tex]

Answer:

The numbers are approximately: 4.000 and 1.000

Step-by-step explanation:

The given parameters can be expressed as:

[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]

[tex]\frac{x}{1000} - \frac{y}{1000} \approx 3[/tex]

Required

Determine the numbers

In each of the equations, multiply by 1000

[tex]1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5][/tex]

[tex]x + y \approx 5000[/tex]

[tex]1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3][/tex]

[tex]x-y \approx 3000[/tex]

So, we have:

[tex]x + y \approx 5000[/tex]

[tex]x-y \approx 3000[/tex]

Add the two equations

[tex]x + x + y - y \approx 5000 + 3000[/tex]

[tex]2x \approx 8000[/tex]

Solve for x

[tex]x \approx 8000/2[/tex]

[tex]x \approx 4000[/tex]

Substitute [tex]x \approx 4000[/tex] in [tex]x + y \approx 5000[/tex]

[tex]4000 + y \approx 5000[/tex]

[tex]y \approx 5000 - 4000[/tex]

[tex]y \approx 1000[/tex]

Using:

[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]

We have:

[tex]\frac{4000}{1000} + \frac{1000}{1000} \approx 5[/tex]

[tex]4.000 + 1.000 \approx5[/tex]

This implies that, the numbers approximates to 4.000 and 1.000, respectively.

The correct margin of error for a 68% confidence interval is option D 4 centimeters.

Let's calculate the margin of error correctly for a 68% confidence interval.

To calculate the margin of error, we need to determine the critical value associated with a 68% confidence interval. For a normal distribution, the critical value is approximately ±1 standard deviation.

Given that the standard deviation is 64 centimeters, the margin of error can be calculated as:

Margin of Error = 1 * (Standard Deviation / √Sample Size)

= 1 * (64 / √256)

= 1 * (64 / 16)

= 1 * 4

= 4

Therefore, the correct margin of error for a 68% confidence interval, based on the given information, is 4 centimeters. The correct answer is option D.

Answer:

The positions can be filled in 2730 ways

Step-by-step explanation:

The number of all posible ways is equal to the number of possibilities of who can become the manager, times the number of possibilities of who can become the associate manager, times the number of possibilities of who can become the assistant manager.

Now...

The number of possibilities of who can become the associate manager = 15

The number of possibilities of who can become the associate manager = 14

(it decrease by one because one person already got the position of manager)

The number of possibilities of who can become the assistant manager = 13

(based on the same logic as for the number of who can become the associate manager)

So now we know the number of ways equals...

15 x 14 x 13 = 2730  

Answer:

1. 11cm

2. 31.2cm

3. 20m

4. 11cm

5. 314feet

Step-by-step explanation:

1. 5.5 × 2 = 11cm

2. 15.6 × 2 = 31.2cm

3. 40m ÷ 2 = 20m

4. From the centre of a circle to the edge is the radius of a circle.

5. Circumference = πD

D = 2r = 2 × 50 = 100

π × 100 = 314feet

The equivalent expression to 12 - 5x is -5x+12. The correct option is B.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is 12 - 5x. The equivalent expression will be calculated as,

-5x+12 = 12 - 5x

Hence, the correct option for the given expression will be B.

Answer:

Step-by-step explanation:

''he Law of Sines is the relationship between the sides and angles of non-right (oblique) triangles . Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.''

The best approximation value of a by using sine rule is 3.0cm. so option C is correct.

The sides and angles of non-right triangles are related according to the Law of Sines.

The relationship between the angles and lengths of the sides:

a/sinA = b/sinB = c/sinC

We know according to law of sines:

a/sinA = b/sinB = c/sinC

by putting the values we can write,

a/sin40° = 4.7/sin95°

a = (4.7 ×sin40°)/sin95°

  =  3.032

by putting the value of Sin40° and Sin95°.

we get a = 3.03cm.

Approximation value of a is 3.0cm.

Given triangle ABC with ∠BAC=40°, ∠ABC=95°,AC = 4.7cm, BC = a cm.

Answer:

A: 171.75

B: 170

Step-by-step explanation:

The mean (or average) can be found by...

- add all the numbers together (we will call this y)

- divide the total sum (or y) by the total amount of numbers used to add

Formula:

(x₁ + x₂ + x₃ + ... + xₙ) ÷ n

For A:

(172 + 130 + 173 + 212) ÷ 4 = 171.75

For B:

(136 + 184 + 168 + 192) ÷ 4 = 170
