Answer:
7500 N
Step-by-step explanation:
Given that,
A hammer claw moves a distance of 0.10 meters to remove a nail.
Resistance force, F = 1500 N
The person move the handle of the hammer 0.5 m
We need to find the effort force. Let it is F'. The mechanical advantage is given by :
[tex]m=\dfrac{effort}{resistance}=\dfrac{d_i}{d_o}[/tex]
Where [tex]d_i\ \text{and}\ d_o[/tex] are input and output distance respectively.
[tex]m=\dfrac{F'}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=0.2\\\\F=7500\ N[/tex]
So, the effort force is 7500 N.

Answer:
42 degrees
Step-by-step explanation:
Answer:
x=42°
Step-by-step explanation:
In any triangle, when all three angles are added together, their sum will always be 180°:
∠1+∠2+∠3=180
Insert any known values:
[tex]29+109+x=180[/tex]
Simplify the addition:
[tex]138+x=180[/tex]
Use inverse operations to find angle three. Subtract 138 from both sides:
[tex]138-138+x=180-138\\\\x=42[/tex]
Therefore, the unknown angle is 42°.

There is a elephant shaped weather vane at the top of a corn dryer tower that is 45 m high. If the weather vane weighs 190 N, what is the Potential Energy that the wether vane has?
Answer:
Potential Energy = 8550 Joules
Step-by-step explanation:
The potential energy of the body is the energy possessed by it due to its position therefore:
Potential energy = mgh
m = mass of the body measured in kg
g= acceleration due to gravity
h= height or distance measured in meters
But in the question asked we are not given mass but weight so
w= mg measured in newtons
We have
w= 190 N
h= 45m
PE= mgh
PE = w h= 190 * 45 = 8550 J
The unit of energy is Joule.

Answer:
Part A: 5 miles per hour or 12 min per mile.
Part B: 30 min to get to his friends house.
Question 16 Part B: 30 minutes.
Step-by-step explanation:
Part A:
36 min for 3 miles so the unit is :
36/3 = 12 so: 1 mile per 12 min and 5 miles per hour.
Part B:
21/2 miles away so:
one mile per 12 min so 2.5 x 12 = he'll get there in 30 min.
Question 16 Part B:
just type in 30.
6 boxes of 3-inch incense sticks for $22.75 is a better buy than 8 boxes for $30 and 10 boxes for $38.00
True
False
Answer:
Step-by-step explanation:
22.75/6 boxes is $3.79 per box
30/8 boxes is $3.75 a box
38/10 boxes is $3.80 a box
68/18=3.70 a box if you combine the last two.
So no, the 6 boxes at $3.79 a box is not a better buy.

B.)y=-x+6/2
C.)y=-x-6/2
Answer:
a
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Subtract x from each side so you get
2y = -x-6
Then divide them by 2 to get
y = -x-6/2
In the diagram below, line segment AB has endpoints at A(-2,-6) and B (3,-1). Give the coordinates of line segment A'B' after a counterclockwise rotation of 90° about the origin.
Answer:
A’ (6,-2)
B’ (1,3)
Step-by-step explanation:
Here, we want to give the coordinates after a counterclockwise rotation of 90 degrees
Given a point with coordinates (x,y)
A counterclockwise rotation at 90 degrees to the origin will yield the coordinates (-y,x)
So A (-2,-6) will be A’ (6,-2) while B (3,-1) will be B’ (1,3)

Timothy has some coins in a jar. He has 6 pennies,8 nickels,10 dimes, and four quarters. What is the ratio of the number of nickels to the number of dimes
Answer:
8:10
Step-by-step explanation:
If Timothy has some coins in a jar. He has 6 pennies,8 nickels,10 dimes, and four quarters. Then 4:5 is the ratio of the number of nickels to the number of dimes
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
Timothy has some coins in a jar.
The number of Pennies = 6
The number of Nickels = 8
The number of dimes =10
The number of quarters =4
We need to find the ratio of the number of nickels to the number of dimes
8/10
4/5
Hence 4:5 is the ratio of the number of nickels to the number of dimes

The ratio of the number of boys to the number of girls in a dance club is 5 : 6. After 6 more boys join the club, the ratio became 13 : 12. How many people were in the club at the start?
44
Step-by-step explanation:
let boys be x and girls be y
x/y=5/6
x=5y/6....(1)
if 6 boys join the club that will be x+6
Therefore:
(x+6)/y=13/12
13y=12x+72
13y-12x=72
Recall x=5y/6
Therefore:
13y-12(5y/6)=72
13y-(2*5y)=72
13y-10y=72
3y=72
y=24 people
Therefore:
x=(5*24)/6
x=20 people
Therefore people in the club before are 20+24=44
