So from that i think the formula would be

so then you find "x" by multiplying 470 x 28 which equals 13,160. Then you divide 13,160 by 40 which equals 329.
X=329
329 students are likely to have phones
Answer:
110687192.78951, 6488.47368421, 4214, 0.0464, 0.03626
SIMPLIFIED WAY OF SAYING IT:
Last One to First Box
3rd One to 2nd Box
1st one to 3rd box
2nd one to 4th box
4th one to 5th box
Step-by-step explanation:
(4.3*10^(6))*(9.8*10^(-4)) = 4,214
(2.9*10^7)*(1.6*10^-9) = 0.0464
(4.7*10^3)*(8.6*10^-7)/(3.8*10^-4)*(6.1*10^2) = 6488.47368421
(4.9*10^3)*(7.4*10^-6) = 0.03626
Last one = 110687192.78951
Answer:
4) Increase from 0 to 1
Step-by-step explanation:
We have to analyze the value of cos(Ф) from -π/2 to 0. This can be done if we simplify evaluate the value of cos(Ф) at these two extreme.

This shows that value of cos(Ф) is 0 at -π/2 or -90 degrees and increased to 0 at 0 degrees.
This answer can be validated if you visualize the graph of cos function. Cos function has a peak at 0 degrees, i.e. a value equal to 1. On right and left side of 0 degrees, the curve starts falling down and eventually touches the horizontal axis at 90 degrees and -90 degrees. This is shown in the graph attached below:
Perimeter of any figure is all its sides summed up
for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)
but we know the length is 7/5 the width
width = w
perimeter = P

and the length is 7/5 of that
W^2-10w-10
Step-by-step explanation:
D=w^2-7
C=3+10w
D-C
(W^2-7)-(3+10w)
W^2-7-3-10w
