b) In a certain weight lifting machine, a weight of 1 kN is lifted by an effort of 25 N. While the weight moves up by 100 mm, the point of application of effort moves by 8 m. Find mechanical advantage, velocity ratio and efficiency of the machine
Answers
The mechanical advantage of the given machine is 40, Velocity ratio is 80 and efficiency is 0.5.
The given question is concerned with finding the mechanical advantage, velocity ratio and efficiency of a weight lifting machine.
The problem has provided the following information:
Weight of the object, W = 1 kN = 1000 NEffort applied, E = 25 NHeight through which the object is lifted, h = 100 mm = 0.1 m Distance through which the effort is applied, d = 8 m
We know that, mechanical advantage = load/effort = W/E and velocity ratio = distance moved by effort/distance moved by the load.Mechanical advantage
The mechanical advantage of the given machine is given by; Mechanical advantage = load/effort = W/E= 1000/25= 40Velocity ratioThe velocity ratio of the given machine is given by;
Velocity ratio = distance moved by effort/distance moved by the load.= d/h = 8/0.1= 80EfficiencyThe efficiency of the given machine is given by;
Efficiency = (load × distance moved by load) / (effort × distance moved by effort)Efficiency = (W × h) / (E × d)= (1000 × 0.1) / (25 × 8)= 0.5
Therefore, the mechanical advantage of the given machine is 40, velocity ratio is 80 and efficiency is 0.5.

If the mean heights of three groups of students consisting of 20,16 and 14 students are 167m, 150m and 1.40m respectively find the mean height of all the student.
Answers
Answer:
1.54 m
Step-by-step explanation:
Given information:
Three groups of students
20 students with a height of 1.67 m16 students with a height of 1.50 m14 students with a height of 1.40 m⇒ Total number of students = 20 + 16 + 14 = 50
To find the mean height of all the students, divide the sum of all the students' heights by the total number of students:
\(\begin{aligned}\implies \sf mean\:height & =\dfrac{(20 \times 1.67)+(16 \times 1.50)+(14 \times 1.40)}{50}\\\\ & = \dfrac{33.4+24+19.6}{50}\\\\ & = \dfrac{77}{50}\\\\ & = 1.54\:\: \sf m\end{aligned}\)
Therefore, the mean height of all the students is 1.54 m
The heights should be
1.67m,1.5m,1.4m as it's looking general and possibleFind mean
\(\\ \rm\Rrightarrow Mean=\dfrac{1.67(20)+1.5(16)+1.4(14)}{14+16+20}\)
\(\\ \rm\Rrightarrow Mean=\dfrac{77}{50}\)

Which expressions correctly show "the sum of the product of 3 and 8 and the product of 12 and 2"? Select two that are correct. *

(12 × 2) + (3 × 8)
3 × 8 × 12 × 2
(3 + 8) × (12 + 2)
(3 × 8) + (12 × 2)
Answers
Answer:
The two correct expressions are:
(12 × 2) + (3 × 8)(3 × 8) + (12 × 2)Step-by-step explanation:
Let 'a' and 'b' be the two numbers.
When we say the product of 'a' and 'b', it
algebraically means: a × bLet 'c' and 'd' be the two numbers.
When we say the product of 'c' and 'd', it
algebraically means: c × dAnd when we say the sum of the product of 'a' and 'b' and the product of 'c' and 'd', it algebraically means:
(a × b) + (c × d)
or
(c × d) + (a × b)
as
(a × b) + (c × d) = (c × d) + (a × b)
So when we say "the sum of the product of 3 and 8 and the product of 12 and 2".
It algebraically means:
(12 × 2) + (3 × 8)
or
(3 × 8) + (12 × 2)
as
(12 × 2) + (3 × 8) = 24 + 24 ∵ 12 × 2 = 24, 3 × 8 = 24
= 48
(3 × 8) + (12 × 2) = 24 + 24 ∵ 3 × 8 = 24, 12 × 2 = 24,
= 48
Therefore, the two correct expressions are:
(12 × 2) + (3 × 8)(3 × 8) + (12 × 2)The translation shown in the graph moves the figure to the right. What kind of translation is shown?

Step-by-step explanation: Since there’s 16 ounces in a pound, all you have to do is multiply 616 by 2 which equals 1,232 calories. 8 times 2 = 16, so 616 times 2 = 1,232
Given the coordinate plane and points provided highlight the point whose distance from point A is approximately 7.1 units
Answers
Point D (-4, -4)
ExplanationsIn order to determine the point whose distance from point A is approximately 7.1 units, we will use the distance formula expressed as:
\(D=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2}\)Given the coordinate points A (1, 1), we need to determine the other coordinate from A that will give a distance of 7.1 units
Using the coordinate point D (-4, -4). The distance AD is calculated as:
\(\begin{gathered} AD=\sqrt[]{(1-(-4))^2+(1-(-4))^2} \\ AD=\sqrt[]{(1_{}+4)^2+(1+4)^2} \\ AD=\sqrt[]{5^2+5^2} \\ AD=\sqrt[]{50} \\ AD\approx7.1\text{units} \end{gathered}\)This shows that the point whose distance from point A is approximately 7.1 units is the coordinate point D
jaci welk is paid $11.95 an hour with time-and-a-half pay for all hours she works over 40 hours a week. last week she worked 45 1/2 hours.
how many over time hours did jaci worked?
what was her overtime rate?
what was her overtime pay?
Answers
Answer:
Number of hours worked overtime = 5.5 hours
overtime rate = $17.925 per hour
overtime pay = $98.59
Step-by-step explanation:
a. Her overtime hours are the number of hours worked over 40 hours, and we are told that she worked 45 1/2 hours last week.
Therefore, her overtime hours = 45.5 - 40 = 5.5 hours
b. overtime rate:
for her overtime rate, we are given that she has a time-and-a-half pay for her overtime hours. This means that she is paid 1.5 times the normal rate for working overtime.
∴ overtime rate = 1.5 × normal rate
overtime rate = 1.5 × 11.95/hour
overtime rate = $17.925/hour
c. overtime pay:
overtime pay = overtime rate × overtime hours worked
overtime pay = 17.925 × 5.5
overtime pay = $98.59

What is the intermediate step in the form (x+a)^2=b as a result of complementing the square for the following equations
Answers
The intermediate step in the form (x+a)²=b as a result of completing the square for the equation x² + 2x = 319 is (x+1)² = 320.
To use completing the square to solve the equation x² + 2x = 319, we have to write the left-hand side of the equation as a perfect square.
Add the square of half of the coefficient of x to both sides of the equation:
x² + 2x + (2/2)² = 319 + (2/2)²
x² + 2x + 1 = 320
The left-hand side of the equation can now be factored as a perfect square:
(x+1)² = 320
This is the equation in the form (x+a)²=b, where a=1 and b=320.
