I believe the correct answers from the choices listed above would be the first and the second option. The conversion factors that are to be used to convert from units of km/min to units of m/hr would be 60 min / 1 h and 1000 m / 1 km. Hope this helps.
Answer:163.54$
Step-by-step explanation:
Given data
Volume of Storage(V)=
Length=2breadth
Let Length be L,Breadth be & height be H
therefore
10=LBH
Now substitutes the values
10=2
5=
Now cost for base is 
Cost for side walls is
Now total cost(C)=
C=20+
+
C=20+24BH+
C=
Now Differentiating With respect to Breadth to get minimum cost
![we\ get\ B=\sqrt[3]{4.5}=1.65m](https://tex.z-dn.net/?f=we%5C%20get%5C%20B%3D%5Csqrt%5B3%5D%7B4.5%7D%3D1.65m)
and mimimum cost C
Answer:
The area is 19.63.
Step-by-step explanation:
The time it will take for the car to skid for 150 feet is 8.23 seconds.
<h3>How to find the time the car will skid?</h3>
The function D(t) = 18t² − 130t gives the distance a car going a certain speed will skid in t seconds.
The time the it would take for the car to skid for 150 feet can be calculated as follows:
Therefore,
D(t) = 18t² - 130t
150 = 18t² - 130t
18t² - 130t - 150 = 0
divide by 3
9t² - 65t - 75 = 0
Hence,
t = 65 ± 5√277 / 18
t = 8.23425471586 or -1.01166666667
Hence,
t = 8.23 seconds.
Therefore, the time it will take for the car to skid for 150 feet is 8.23 seconds.
