To have an effective safeguarding system, specific and detailed training of workers must also be included.

What constitutes the foundation of the safety system?

 Any portion of the operator's body, including the hands, arms, and other body parts, must not come into touch with potentially harmful moving parts.

                              A strong safety system completely avoids the chance of the operator or another worker putting their bodies in close proximity to dangerous moving parts.

What are the two main sorts of protection strategies?

There are primarily two types of safeguarding: hard guards and safeguarding gadgets. Hard guards act as a physical barrier between workers and moving parts.

                            Safeguarding devices, however, stop unintentional access to dangers. A machine that needs two hands to operate it, for instance, ensures that neither hand may enter the danger zone.

Answer:
2. Total Hours= 38+5 = 43

Step-by-step explanation:

2. Wage at Normal rate80 *38 = 3040
Extra Sum of Money then Normal wage 3640-3040 = 600

Overtime rate 80*1.5= 120
Overtime hours 600/120=5

3. (a) 210/3 = 70km/hr
        140/(2.75*) = 50.91 km/hr
         *2.75= 2+ (45/60)
 

The total cost of painting his basement floor is $51.70.

To find the total cost of the paint including HST, we first need to calculate the total area of the basement floor that needs to be painted. We can do this by multiplying the length by the width:

Area of basement floor = length x width

Area of basement floor = 2.5 m x 2.3 m + 1.8 m x 2.3 m

Area of basement floor = 5.75 m² + 4.14 m²

Area of basement floor = 9.89 m²

Now, we can calculate the number of cans of paint needed:

Number of cans = Area of basement floor / Area covered by each can

Number of cans = 9.89 m² / 3.5 m²

Number of cans = 2.8257

Number of cans = 3

The total cost of the paint without HST would be:

Total cost = Number of cans x Cost per can

Total cost = 3 x $15.25

Total cost = $45.75

To calculate the HST, we need to multiply the total cost by the HST rate (13% or 0.13):

HST = Total cost x HST rate

HST = $45.75 x 0.13

HST = $5.95 (rounded to two decimal places)

Finally, we can find the total cost including HST by adding the total cost and the HST:

Total cost including HST = Total cost + HST

Total cost including HST = $45.75 + $5.95

Total cost including HST = $51.70

Therefore, the total cost of the paint including 13% HST is $51.70.

Answer: To find the distance between two points on a grid, we can use the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

In this case, the coordinates of the middle school are (-5, 3), and the coordinates of the library are (2, 3). So we have:

distance = sqrt((2 - (-5))^2 + (3 - 3)^2)

distance = sqrt((2 + 5)^2 + 0^2)

distance = sqrt(7^2)

distance = 7

Therefore, the library is 7 miles away from the middle school.

To find the integer that describes the change in temperature, we can divide the total temperature drop by the number of hours:

32 ÷ 4 = 8

Therefore, the temperature dropped by 8 degrees Fahrenheit each hour. The integer that describes the change is -8, since the temperature decreased.

Answer: To find the integer that describes the change in temperature, we need to divide the total change in temperature (32° F) by the number of hours over which the temperature dropped (4 hours). This will give us the amount that the temperature dropped by each hour.

So, dividing 32 by 4, we get:

32 ÷ 4 = 8

Therefore, the temperature dropped by 8 degrees Fahrenheit each hour.

The choice in the blank to make the statement true will be D. between $17 and $30)

Revenue = Price per book × Number of books sold = (745 - 30P) b

Since the store needs to sell at least 235 books, we have:

Revenue ≥ 235 × Price per book = 235(745 - 30P)

Simplifying this inequality, we get:

745b - 30Pb ≥ 235 × 745

P ≤ (745/30) - (235/b)

Since we want to find the minimum profit per book sold, we need to maximize the value of (235/b). The maximum value of (235/b) occurs when b is minimized

If we assume that the cost per book is constant, then the profit per book sold will increase as the price per book increases. Therefore, we can say that the minimum profit per book sold that would enable the store to sell at least 235 books is greater than $17.

The frequency distribution is calculated below

The dataset is given as

32,22,19,18,43,42,40,43,18,21,31,26,22,25,47,40,26,32,34,22,35,38,34,41,36,25,22,45,48,26,28,38,35,19,47,28,26,35,38,35.

To construct a frequency distribution using class intervals, we calculate the class width as follows:

Class width = Range / Number of intervals

So, we have

Class width = (48 - 18)/5 = 6

Now we can construct the frequency distribution table:

Class Interval Frequency

18 - 23            9

24 - 29            8

30 - 35            9

36 - 41             7

42 - 47            6

48 - 53             1

The class mark for each class can be calculated as:

Class mark = (Lower limit + Upper limit) / 2

For the class boundaries, we use the following formula

Lower boundary = Lower limit - 0.5

Upper boundary = Upper limit + 0.5

For the cumulative frequency of the distribution, we need to add up the frequencies of each class and all the preceding classes.

Lastly, for the relative frequency we divide each frequency by the total frequency (40)

Using the above as a guide, we have

Interval Frequency   Boundaries Mark CF

Answer:

The distance between the student and the mirror is 7.5 feet.

Step-by-step explanation:

We can use similar triangles to solve this problem.

Let's call the distance between the student and the mirror "d". We can create a right triangle with the student's height as one leg, the distance "d" as the other leg, and the hypotenuse being the line from the student's eyes to the top of the school. Let's call the length of this line "h".

We can also create a second right triangle with the height of the school as one leg, the distance from the school to the mirror as the other leg, and the hypotenuse being the same line from the student's eyes to the top of the school.

Since these two triangles share an angle (the angle formed by the line from the student's eyes to the top of the school and the ground), they are similar triangles. This means that the ratios of their corresponding sides are equal.

We can set up the following proportion:

(student height) / d = (school height) / (distance from school to mirror)

Plugging in the given values, we get:

4.5 / d = 30 / 50

Simplifying, we get:

4.5 / d = 3 / 5

Cross-multiplying, we get:

3d = 22.5

Dividing by 3, we get:

d = 7.5

Therefore, the distance between the student and the mirror is 7.5 feet.

The distance of the student to the mirror, is 7.5 ft

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Given that, a mirror is placed outside a school the distance from the school to the mirror is 50 ft and the height of the school is 30 ft we need to find the distance of the student to the mirror,

This arrangement is creating two similar triangles, here we will use the properties of the similar triangles, to find the distance of the student to the mirror,

Therefore,

30 / 4.5 = 50 / d

d = 50 x 4.5 / 30

d = 225 / 20

d = 7.5

Hence, the distance of the student to the mirror, is 7.5 ft

The LCD we can use to simplify the equation is (2-r)(2+r) = 4 - r².

The lowest common denominator is defined as the set of fraction denominators with the lowest common multiple. The lowest positive integer with more than one denominator in the set is LCD.

1. We can use the formula:

distance = rate × time

For the upstream journey:

distance = 4 miles

rate = 2 - r (since Dara is paddling against the current)

time = 4/(2-r) hours

For the downstream journey:

distance = 4 miles

rate = 2 + r (since Dara is paddling with the current)

time = 4/(2+r) hours

We can fill in the table as follows:

                       Distance (mi)    Avg Speed (mph)    Time (h)

With Current:            4                     2+r                    (4)/(2+r)

Against Current:       4                    2-r                       (4)/(2-r)

2. We know that the total time for the round trip is 6 hours:

4/(2-r) + 4/(2+r) = 6

3. Multiplying both sides by the LCD (2-r)(2+r), we get:

4(2+r) + 4(2-r) = 6(2-r)(2+r)

Simplifying, we get:

8 = 12 - 2r²

Rearranging, we get:

r² = 2

Taking the square root of both sides, we get:

r = ±√2

Since the current is flowing in one direction, we take the positive square root:

r = √2 ≈ 1.41 miles per hour

The LCD we can use to simplify the equation is (2-r)(2+r) = 4 - r².

4. To the nearest hundredth, the rate of the current is approximately 1.41 miles per hour, which is option B: About 1.15 miles per hour (rounded to two decimal places).

The equation of a rational function that has been translated left 2 units and shifted up 1 unit is: f(x) = (a(x - 2) + b + 1) / (c(x - 2) + d)

A relation is a function if it has only One y-value for each x-value.

A general form of a rational function is:

f(x) = (ax + b) / (cx + d)

To translate this function left 2 units, we need to replace x with x + 2. This gives us:

f(x + 2) = (a(x + 2) + b) / (c(x + 2) + d)

To shift this function up 1 unit, we need to add 1 to the numerator. This gives us:

f(x + 2) = (a(x + 2) + b + 1) / (c(x + 2) + d)

Therefore, the equation of a rational function that has been translated left 2 units and shifted up 1 unit is: f(x) = (a(x - 2) + b + 1) / (c(x - 2) + d)

Therefore , the solution of the given problem of triangle comes out to be L = 3(√(h²) + ((w/2²))) + 3h .

A triangular is a polygon because it has 2 different or more additional parts. It has a straightforward rectangle form. Only the sides A, B, and C can differentiate a triangle from a parallelogram. When the sides are not exactly collinear, Euclidean geometry results in a singular surface rather than a cube. If a shape has three edges and three angles, it is said to be triangular.

Here,

Given the height and breadth of the top of the frame, we can use the Pythagorean theorem to determine the length of each side of the triangle.

Let's assume the height is h feet and the width of the top of the frame is w feet. The triangle's side lengths can then be calculated as follows:

=> s =√((h²) + ((w/2)²))

We must add up the lengths of all the pipe segments that will be used to build the frame in order to determine the total quantity of steel pipe required.

The following formula can be used to determine how much steel tubing is required:

=>  L = 3s + 3h

where h is the height of the frame and s is the length of each edge of the triangle.

Using the method instead of s, we obtain:

The solution for the given system of equations is (1,0) using the addition method.

The addition method, also known as the elimination method, is a technique used to solve a system of linear equations by adding the two equations together in such a way that one of the variables is eliminated.

Multiply the first equation by -2:

-10x - 12y = -10

Add the second equation to the first:

-10x - 12y = -10

10x + 12y = 10

0 + 0 = 0

We can solve one of the original equations for x in terms of y and then replace into the equation to represent the solutions in terms of y. For instance, when we solve the first equation for x, we obtain:

5x + 6y = 5

5x = 5 - 6y

x = (5 - 6y)/5

By substituting this into the second equation, we get:

10x + 12y = 10

10((5 - 6y)/5) + 12y = 10

2(5 - 6y) + 12y = 10

10 - 4y = 10

F1 = 1167.35N and F2 = 1932.65N are the contact support forces on the beam

For the torques, let the axis be at support 2 and consider torques and the counterclockwise rotation is positive.

Let m = mass of athlete and M = mass of beam.

Thus, the equilibrium of torques will be:

Mg(1.96) - mg(0.54m) - F1(3.92) = 0

Substitute the values and solve for F1:

(250 * 10 * 1.96) - (60 * 10 * 0.54) - 3.92F1 = 0

3.92F1 = 4900 - 324

3.92F1 = 4576

F1 = 1167.35N

Note: The weight of the beam is acting at the center and the distance from center to axis at support 2 is 1.96m.

Balancing forces in the vertical direction, we have:

F1 + F2 - Mg − mg = 0

1167.35 + F2 - (250 * 10) − (60 * 10) = 0

1167.35 + F2 - 2500 - 600 = 0

F2 = 1932.65N
