The radius of the  copper specimen before deformation was 8 mm of a cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm

Given information:

To find the radius of the copper specimen before deformation, we'll use the formula for calculating the ductility:

Ductility (%el) = ((Final radius - Initial radius) / Initial radius) * 100

Let's denote the initial radius as "r" (in mm). The final radius is 10 mm (after cold-working).

25% = ((10 - r) / r) * 100

Now, solve for "r":

25% = (10 - r) / r

Convert percentage into fraction:

25/100 = (10 - r) / r

Convert fraction into decimal:

0.25 = 10 - r/r

on Cross-multiplication gives:

 0.25r = 10 - r

Add r on both sides gives,

1.25r = 10

On dividing by 1.25 gives:

r = 8 mm

So, the radius of the copper specimen before deformation was 9.75 mm.

Answer: 176 cubic cm

Step-by-step explanation:

Formula for finding volume is l x w x h

The first rectangle on the bottom:

2 x 2 x 8 = 32

The second rectangle next to it:

3 x 6 x 8 = 144

Now add the two values to get the volume of the figure

144 + 32= 176

7cm²+5cm²=10cm²

14cm+25cm=100cm

39=100

1 hen lays 1 egg in 2 minutes

You need 250 chickens

The total number of hen needed to lay 500 eggs in 500 minutes = 2

"A process of finding the value of a single unit, and based on this value we can find the required value. "

For given question,

Two hens lay two eggs in two minutes.

This means, two hens lay 1 egg per minute

So, they lay 500 eggs in 500 minutes.

Therefore, the total number of hen needed to lay 500 eggs in 500 minutes = 2

Answer:

V = 54π or V = 169.56 units³

Step-by-step explanation:

The volume of a cylinder is given by the formula:

V = πr²h

If we use 3.14 as pi we get this:

V = (3.14)×(3)²×(6)

V = 3.14×9×6

V = 3.14×54

V = 169.56

Since it is volume the units will be units³

So our final answer is 169.56 units³

If you wanted an exact in pi form you would do the same steps but not simplify pi:

V = πr²h

V = π×(3)²×6

V = π×9×6

V = 54π

Using vector concepts, it is found that the correct option regarding the magnitude and the tail is given by:

9.2 units, 49.4° north of west

To find them, we subtract the end coordinate by the start coordinate, hence:

RS = S - R = (-2, 1) - (4,-6) = (-6,7).

The magnitude is given by the square root of the sum of the squares of each coordinate, hence:

[tex]|RS| = \sqrt{(-6)^2 + 7^2} = \sqrt{85} = 9.2[/tex]

Considering a xy graph, the vector is decaying, that is, moving north of west, hence the correct option is:

9.2 units, 49.4° north of west

Here Allie mistook the x and y axis completely oppositely.

→ First should be the x axis and then the y axis, (x, y)

Answer:

Step-by-step explanation:

Coordinates of a point are usually represented by (x, y) where x describes the horizontal distance from the y-axis and y describes the vertical distance from the x-axis.

Point A

4 units from the y-axis ⇒ x = 4

6 units from the x-axis ⇒ y = 6

A = (4, 6)

Point B

2 units from the y-axis ⇒ x = 2

9 units from the x-axis ⇒ y = 9

B = (2, 9)

Point C

0 units from the y-axis ⇒ x = 0

4 units from the x-axis ⇒ y = 4

C = (0, 4)

Point D

Allie has mixed up the x and y coordinates of D.

7 units from the y-axis ⇒ x = 7

3 units from the x-axis ⇒ y = 3

D = (7, 3)

Step-by-step explanation:

The equation of the linear function f(x) is f(x) = 4x - 3. So, the answer is B) 4x - 3.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
We can use the two given data points to determine the equation of the linear function f(x) using the slope-intercept form:

f(x) = mx + b

where m is the slope and b is the y-intercept.

First, we can find the slope of the function by using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

where (x₁, y₁) = (2, 5) and (x₂, y₂) = (4, 13)

m = (13 - 5) / (4 - 2) = 4

Now we can use the slope and one of the given points to solve for the y-intercept:

5 = 4(2) + b

b = -3

Therefore, the equation of the linear function f(x) is f(x) = 4x - 3.
