First, let's convert 210 minutes to hours:
Now, to calculate the velocity in mph, let's divide the distance in miles by the time in hours:
Answer:
Multiply the first term of each binomial together.
Multiply the outer terms together. (2x)(–1) = –2x.
Multiply the inner terms together. (3)(3x) = 9x.
Multiply the last term of each expression together. ...

The answer is 88.8% how i got it is by:
30-18= 12 which is the number of member that had an average of 84
then multiply 12 times 84 = 1008 (keep this number)
last you multiply 18 by 92 which equals 1656
add 1008 and 1656 together and get 2664.
divide 2664 / 30 and you get the average of 88.8
Answer:
d = 1.46 m
Step-by-step explanation:
We'll begin by obtaining the relationship between the force (F) and the distance (d). This can be obtained as follow:
From the question given above,
F is inversely proportional to square of d. This can be written as:
F ∝ 1/d²
F = K/d²
Cross multiply
K = Fd²
But:
Force (F) = 0.006 N
Distance (d) = 4 m
Constant (K) =?
K = Fd²
K = 0.006 × 4²
K = 0.006 × 16
K = 0.096 Nm²
Therefore, the relationship between the force (F) and the distance (d) is:
F = K/d²
F = 0.096 / d²
Finally, we shall determine the distance when the force is 0.045 N. This can be obtained as follow:
Force (F) = 0.045 N
Constant (K) = 0.096 Nm²
Distance (d) =?
F = K/d²
0.045 = 0.096 / d²
Cross multiply
0.045 × d² = 0.096
Divide both side by 0.045
d² = 0.096 / 0.045
Take the square root of both side.
d = √(0.096 / 0.045)
d = 1.46 m.
