2 inches 3 inches Pivot. If 60 lbs. of force must be applied to the valve for it to open, how much upward force must push rod X apply for the valve to open?
A 60 lbs
B.40 lbs
C 30 lbs
D.20 lbs
E 15 lbs
We can solve this problem by stating that the summation of momentums must be zero. That is, the momentum at one end of the pivot must be equal to the momentum at the other end.
Momentum 1 = Momentum 2
Since Momentum is the product of Force and Distance, and with this rule created, we can say that:
F1 * d1 = F2 * d2
Where,
F1 = 60 lbs
d1 = 2 inches from the pivot
F2 = unknown X
d2 = 3 inches from the pivot
Substituting to the equation to find for F2:
60 lbs * 2 inches = F2 * 3 inches
F2 = 40 lbs
Therefore 40 lbs of upward force must be pushed to open the valve.
Answer: B
Final Answer:
40 lbs of upward force must be pushed to open the valve that is option B is correct.

Susan starded her homework at 1:59 p.m. And finished her homework 96 minutes later. Susan had volleyball practice at 4:00p.m.
How much time did Susan have between finishing her homework and the beginning of volleyball practice ?
The time Susan had between finishing her homework and the beginning of volleyball practice is 25 minutes.
How much time did Susan have?The first step is to convert the time she used to do her homework to hours and minutes.
1 hour = 60 minutes
96 minutes = 1 hour 36 minutes
Time she finished her homework = 1:59 + 1 : 36 = 3 : 35
Time she had = 4 - 3 : 35 = 25 minutes

If a person weighs 240 pounds on Earth, what would be the difference in weight of the same person on Mars and on the Moon
Answer:
Mars: [tex]\Delta W = 144\,lbf[/tex], Moon: [tex]\Delta W = 199.2\,lbf[/tex]
Step-by-step explanation:
The gravitational acceleration experimented by the same person on the Moon is equivalent to a sixth of the indicator on Earth and the same indicator on Mars is about 40 % of the terrestrial acceleration. Then, the difference in weight are computed below:
Mars:
[tex]\Delta W = (1 - 0.4) \cdot (240\,lbf)[/tex]
[tex]\Delta W = 144\,lbf[/tex]
Moon:
[tex]\Delta W = (1 - 0.17) \cdot (240\,lbf)[/tex]
[tex]\Delta W = 199.2\,lbf[/tex]

What is the length of segment RS
Answer: 13 units
Step-by-step explanation:
The length of line segment AB with points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)[/tex] is given by distance formula as :
[tex]\text{AB}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Now, the length of line segment RS with points [tex]R(-4,-3)\ and\ S(1,9)[/tex] is given by distance formula as :
[tex]\text{RS}=\sqrt{(1-(-4))^2+(9-(-3))^2}\\\Rightarrow\ RS=\sqrt{(5)^2+(12)^2}\\\Rightarrow\ RS=\sqrt{25+144}=\sqrt{169}\\\Rightarrow\ RS=13[/tex]
Hence, the length of segment RS= 13 units
Aldora decides to join a gym for a minimum of one month to train for a triathlon. The gym charges a joining fee of $100 and a monthly fee of $36. If x represents the number of months that Aldora is a member of the gym, the equation below can be used to determine C, her total membership fee for that duration of time:
100 + 36x = C
Aldora has allocated a maximum of $352 to spend on her gym membership. Which number line shows the possible number of months that Aldora can be a member of the gym?

Michael jogs 3,520 yards every day. What is the distance in miles that he will jog in 10 days? (1 mile = 1,760 yards) How do I figure the problem? Divide 10 into 3,520?
divide 3520 by 1760 to get miles per day
3520/1760 = 2 miles per day
2 x 10 = 20 miles in 10 days
Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?
y = 2x – 2
y = 2x + 2
y = x + 2
y = x – 2
Answer:
The correct option is 3.
Step-by-step explanation:
If a line passing through two points then the equation of line is
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
It is given that CD passes through points (0, 2) and (4, 6), so the equation of line is
[tex]y-2=\frac{6-2}{4-0}(x-0)[/tex]
[tex]y-2=\frac{4}{4}(x)[/tex]
[tex]y-2=x[/tex]
Add 2 on both the sides.
[tex]y=x+2[/tex]
The equation of line CD is y=x+2. Therefore the correct option is 3.

The side length is 4, and the side measure of the largest square tile is 4 feet.
What is an expression?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 you want to lay tile in a room of your house. The room is 12 feet by 8 feet.
Tiles 4 feet by 4 feet will fill up the entire 96 sq ft area in just six tiles; three rows and two columns of them.
A tile with the dimensions of 4 x 4 has an area of 16 sq ft, which divides evenly in 96 (96/16=4).
16 is the largest square that divides into 96, making it the largest square tile that can be used to cover the entire floor smoothly without cutting. The side length is 4.
Therefore, the side length is 4, and the side measure of the largest square tile is 4 feet.

1. The work of a student to solve the equation 2(3x − 4) = 8 + 2x + 4 is shown below:
Step 1: 2(3x − 4) = 8 + 2x + 4
Step 2: 5x − 6 = 12 + 2x
Step 3: 5x − 2x = 12 + 6
Step 4: 3x = 18
Step 5: x = 6
In which step did the student first make an error and what is the correct step?
Step 2; 6x − 6 = 2(6 + x + 2)
Step 2; 6x − 8 = 12 + 2x
Step 3; 5x − 2x = 12 − 6
Step 3; 5x + 2x = 12 + 6
2. The steps below show the incomplete solution to find the value of m for the equation 4m − 2m + 4 = −1 + 13:
