Answer:
104x0.23
Step-by-step explanation:
?
Answer:
Step-by-step explanation:
We have been given that the variables y and x have a proportional relationship, therefore, we can represent the relationship between x and y as: , where k is proportionality constant.
Let us substitute x=3 and y=15 in above equation to find the value of k.
Now let us substitute k=5 and y=4 in our proportionality equation to find the corresponding value of x.
Therefore, the value of x will be 0.8, when y equals to 4.
Answer:
49N
Step-by-step explanation:
Step one
Given
When the force of 63 N acts on a certain object
the acceleration of the object is 9/ms^2
Firstly, we need to calculate the mass m
F=ma-------1
m= F/a
m= 63/9
m= 7kg
Step two:
Also, if the acceleration of the object becomes 7 m/s^2
then the force
Note: the mass remains the same= 7kg
F=ma
F=7*7
F= 49N
Answer:
first side =9,second side =12,third side =15
Step-by-step explanation:
total ratio =3+4+5
=12
first side=3/12×36
=9
second side=4/12×36
=12
=third side=5/12×36
=15
