Answer:
The speed of car in miles per minute is
miles per minute and
The speed of car in mile per hour is 40 miles per hour,
Step-by-step explanation:
Given as :
The distance cover by car = 2
=
miles
The Time taken by car to cover distance = 3
min =
min
The speed o car in miles per minute = S miles/min
So, Speed = 
Or, S =
mie per min
∴ S =
miles per minute
Now, Let The speed of car in miles per hour = x miles/h
So, Time in hour =
×
=
hours
So , Speed = 
Or, x =
miles per hours
Or, x = 40 miles per hours
Hence The speed of car in miles per minute is
miles per minute and the speed of car in mile per hour is 40 miles per hour, answer
Answer:

Step-by-step explanation:
The question is not correct (particularly the expression for the area)
A=2lh+2wh
Now we are expected to solve for l, that is we are going to make l subject of the formula, we have
let us take the second term on the RHS to the LHS

we can now divide both sides by 2h we have

hence the expression for the length is 
Answer:
D
Step-by-step explanation:
To keep it short, refer to triangle exterior angle theorem.
Edit: If you want the full explanation,
A isn't the answer. The triangle exterior angle states that the measure of the 2 triangle interior add up to the the exterior angle of the other interior angle within the triangle.
Meaning that
measure of angle 1 equal the measure of 3 and 4 combined.
B. is wrong they are equal to each other because angle 2 is equal to angle 2
angle 1 is equal to angle 3 and 4
So they are equal
C.Wrong unless it a 30 60 90 triangle or 45 45 90 triangle, C is wrong
D. is right since measure of angle 4 and angle 3 add up to angle 1, angle 4 would be lesser than angle 1.
Answer:
The formula used to calculate the sphere radius is: r = ∛((3/4) · V / π) Symbols. r = Sphere radius; V = Sphere volume; π = Pi = 3.14159… Volume of Sphere. Enter the volume contained within a sphere. Radius of Sphere. This is the radius of a sphere that corresponds to the specified volume.
Step-by-step explanation:
This is the function

Then factor 2 out

Divide both side by two and use the quadratic formula to get the following

X=3 And x=-2 and don't forget to Chek them
