Answer:
d)c=4.20h
Step-by-step explanation:
the rate is 16.80 /4
4.20 per hour
earn = hours * rate
c = 4.20*h
The dimensions of a closed rectangular box are mathematically given as
w=14
h=14
This is further explained below.
<h3>Find the dimensions of a closed rectangular box:</h3>
In the geometry of the plane based on Euclidean theory, a rectangle is a quadrilateral that has four right angles.
It is also possible to refer to it as a parallelogram with a right angle or an equiangular quadrilateral. Equiangular refers to a quadrilateral in which each of its angles is equal to the others in the quadrilateral.
Generally, the equation for Area the is mathematically given as
Area=2w²+4hw
Therefore
![$$A=2 w^2+4\left(\frac{2744}{w^2}\right) * w\\\\$$$$A=2 w^2+\frac{10976}{w}\\\\$$$$d A / d w=4 w-10976 / w^2\\\\$$$$w=\sqrt[3]{2744}\\\\$$$$w=14$$](https://tex.z-dn.net/?f=%24%24A%3D2%20w%5E2%2B4%5Cleft%28%5Cfrac%7B2744%7D%7Bw%5E2%7D%5Cright%29%20%2A%20w%5C%5C%5C%5C%24%24%24%24A%3D2%20w%5E2%2B%5Cfrac%7B10976%7D%7Bw%7D%5C%5C%5C%5C%24%24%24%24d%20A%20%2F%20d%20w%3D4%20w-10976%20%2F%20w%5E2%5C%5C%5C%5C%24%24%24%24w%3D%5Csqrt%5B3%5D%7B2744%7D%5C%5C%5C%5C%24%24%24%24w%3D14%24%24)
In conclusion, Where h is
h=2744/w²
Hence
h=2744/14^2
h=14

13/25 would be the smallest fraction you can get otherwise 52/100 if your teacher doesn’t want it reduced hope this helped
