143.17 times 1.35 = 193.28
To solve this, we need to follow <em>PEMDAS </em>(Order of Operations)
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
Following this order of math will get you your answer for any math problem.
First we'll do -4*1/3, which gets us -4/3. Then we'll add 5 to get

Answer:
<h2>16kg</h2>
Step-by-step explanation:
This problem is borers on elasticity of materials.
according to Hooke's law,<em> "provided the elastic limit of an elastic material is not exceeded the the extension e is directly proportional to the applied force."</em>
where F is the applied force in N
k is the spring constant N/m
e is the extension in meters
Given data
mass m= 24kg
extensnion=15cm in meters= =
we can solve for the spring constant k
we also know that the force F = mg
assuming
therefore
We can use this value of k to solve for the mass that will cause an extension of
Answer:
21 degrees is the answer
Step-by-step explanation:
Answer:
a) 3 people will need 35 days to paint the bridge
b) p=105/t
Step-by-step explanation:
a)
We have 7 people each one is to work 15 days, so the bridge needs a total of 7(15) days of work
7(15)=105
Then we have 3 people each one is to work t days, altogether should do a total of 105 days of work
3(t)=105
Solve for t
t=35
b)
Substitute p for 3 in the second equation
p(t)=105
Solve for p
p=105/t
