Answer:
2400 foot pounds
Step-by-step explanation:
The amount of work done by the four men is 1200 ft-lbs. so option B is correct.
How to calculate work done?The muscular work done by each man is equal to the weight of the boxes carried multiplied by the vertical distance moved.
The weight of each box is 5 pounds, and each man carries 20 boxes, so the total weight carried by each man is:
20 boxes x 5 pounds/box = 100 pounds
The vertical distance moved is the height of the ramp, which is 30 feet.
Therefore, the muscular work done by each man is:
Muscular work = weight x vertical distance
Muscular work = 100 pounds * 30 feet
Muscular work = 3000 ft-lbs
Since there are four men carrying boxes, the total muscular work done is:
Total muscular work = 4 * 3000 ft-lbs = 12000 ft-lbs
Therefore, the answer is B. 1200 ft-lbs.

Step-by-step explanation:
Answer:
28, 30, and 32
Step-by-step explanation:
It gives you the equation, so you just need to solve for x first:
[tex]x+3+x-1+x+1=90\\3x+3=90\\3x=87\\x = 29[/tex]
Plug that into each:
29 + 3 = 32
29 - 1 = 28
29 + 1 = 30

Remark
The trick is to solve the inequality. The last step is very tricky. Be careful with it.
Equation
15≤ -3x + 6 Subtract 6 from both sides
15-6 ≤ - 3x + 6 - 6 Combine
9 ≤ -3x Divide by - 3
9/-3 ≥ -3x/-3 Notice what happened to the less than or equal to
-3 ≥ x
Now there are 2 problems remaining.
1) why did the inequality turn around?
It turned around because when you divide by a number less than 0, the inequality turns around because the negative numbers work opposite to the positive numbers .
18 > 6
-18 < - 6
2) So which graph is correct.
The largest number that is possible is -3 The arrowhead should be pointing left.
In addition, the circle should be blacked in.

Mhanifa please help! Explain how you can use the perpendicular bisector of a segment to draw an isosceles triangle.
Answer:
If you construct the perpendicular bisector of a line segment, every point on the perpendicular bisector will be the same distance from both point A and point B.
To construct an isosceles triangle, you can start from any point on the perpendicular bisector and draw line segments to point A and to point B
The required steps are in the solution that to use the perpendicular bisector of a segment to draw an isosceles triangle.
What is an isosceles triangle?An isosceles triangle is defined as a triangle with two sides of equal length.
To use the perpendicular bisector of a segment to draw an isosceles triangle, you can follow these steps:
Draw the segment for which you want to find the perpendicular bisector.
Use a compass to draw a circle with its center at the midpoint of the segment.
With the compass still set to the same radius, draw two arcs that intersect the segment at two points. These points will be the base points of the isosceles triangle.
Draw a line through the midpoint of the segment and the point where the arcs intersect the segment. This line is the perpendicular bisector of the segment.
Use a ruler to draw a line segment connecting the base points of the isosceles triangle.
Use a ruler to draw a line segment connecting the apex of the isosceles triangle (the point where the perpendicular bisector intersects the base) to one of the base points.
At this point, you should have a triangle with two equal sides and a right angle at the apex. This is an isosceles triangle.

2 + (3 – 2 x 2) x 1
Answer:
Step-by-step explanation:
2 + (3 – 2 x 2) x 1
This is what I remember, but you need to check this order of arithmetic operations.
Parentheses first then exponents ( you don't have any) multiplication and division left to right and then addition and subtraction again left to right
2 + (3 – 2 x 2) x 1 so 3 – 2 x 2 equals 3 - 4 which equaltes to
2 + (-1) x 1 -1 x 1 = -1
2 + (-1) x 1 is to clearer to me than 2 + -1 x 1 maybe not

Answer:
74.8 m²
Step-by-step explanation:
The hint is usually a good place to start.
A = (1/2)(11 m)(15 m)sin(115°) ≈ 74.8 m²
_____
Additional comment
As is often the case with over-specified triangle problems, the answer you get depends on how you work the problem. Here, the hint suggests you use the angle. If you use the three side lengths, you find the angle is 114.7° and the area is about 74.9 m².

pam is 17 years old and her sister is 9. her two brothers are 11 and 7 years old. what is the mean of their ages
Answer:
11
Step-by-step explanation:
17+9+11+7 divided by 4
because the mean= sum of the terms divided by the number of terms
the sum= 17+9+11+7=44
the number of terms= 4
44 divided by 4= 11
Answer:
(17+9+11+7) / 4 mean is an average
it is equal to the sum of the elements divided by the number of elements
the sum is 44
the number of elements is 4
the mean is the average= 44/4=11

3x-3y = 11
3x + 10y=3
Answer:
x = 3.05 and y = -0.615
Step-by-step explanation:
The given equations are :
3x-3y = 11 ...(1)
3x + 10y = 3 ...(2)
Subtract equation (2) from (1).
3x-3y-(3x + 10y) = 11-3
-3y-10y = 8
-13y = 8
y = -0.615
Put the value of y in equation (1).
3x-3(-0.615) = 11
3x = 11 -1.845
3x = 9.155
x = 3.05
Hence, the values of x and y are 3.05 and -0.615.
Ind the volume of a pyramid with a square base, where the side length of the base is 15.3\text{ m}15.3 m and the height of the pyramid is 19.6\text{ m}19.6 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
1,487.3m³
Step-by-step explanation:
Volume of a square based pyramid is expressed as;
V = BH/3
B is the base area
H is the height of the pyramid
Since the side length of the base is 15.3m;
Base area = L²
Base area = 15.3²
Base area = 234.09m²
Height of pyramid = 19.6m²
Get the volume
Volume of the square based pyramid = (234.09*19.6)/3
Volume of the square based pyramid =1,487.3m³ (to the nearest tenth)

Answer:
Step-by-step explanation:
a) One can get maximum score when all the 20 questions answered are correct.
Maximum score = 20*3 = 60 points
b) Minimum score = 20 * (-2) = -40 points
c) Points for correctly answered questions = 10*3 = 30
Incorrectly answered questions = 14 - 10 = 4
Points for incorrectly answered questions = 4 * (-2) = -8
Total score = 30 + (-8) = 22
d) Points for correctly answered questions =5*3 = 15
Points for incorrectly answered questions = 13 * (-2) = -26
Total score = 15 + (-26) = -11
