Answer:
e none is the answer
Step-by-step explanation:
We already know that the hourly rate for John is : 1/6 and the hourly rate for Rick is : 1/8. What we don`t know is a hourly rate for Molly and we will call it 1 / x.
The hourly rate for all together is: 1 / 3
An equation is:
1 / 3 = 1 / x + 1 / 6 + 1 / 8
1 / 3 = 1 / x + 4 / 24 + 3 / 24
1 / 3 = 1 / x + 7 / 24
1 / x = 1 / 3 - 7 / 24
1 / x = 8 / 24 - 7 / 24
1 / x = 1 / 24
1 / 3 = 1 / 24 + 1 / 6 + 1 / 8
The hourly rate for Molly is 1 / 24. Molly can paint the room alone for 24 hours.
Answer:
14 m/s²
Step-by-step explanation:
From the question
a ∝ F/m.............. Equation 1
Where a = aceleration, m = mass, F = force
make F the subject of the equation
F = ma............ equation 2
Given: m = 7 kg, a = 4 m/s²
Therefore,
F = 7(4)
F = 28 N
For another object whose mass is 2 kg,
Make a the subject of equation 2
a = F/m
a = 28/2
a = 14 m/s²
s(s)
To find area you multiply two opposing sides. For a square, all the sides are the same, so if one side is 2; you would multiply 2(2) to get the answer. This is why if a side length is s, the expression to 'solve' this woulf be s(s)
