Answer:
km
Step-by-step explanation:
We are given;
- The are of a rectangle as 7/10 km²
- Width of the rectangle is 1/3 km
We are required to find the length of the rectangle;
We need to know how to find the area of a rectangle first;
Area of rectangle = Length × Width
Rearranging the formula;
Length = Area of rectangle ÷ Width
= 7/10 km² ÷ 1/3 km
We get;
(improper fraction)
Thus, the length of the rectangular park is km
Set up a proportion, 20 over 25% and x over 60% and the answer is 48

Answer:
128 seconds
Step-by-step explanation:
The sun subtends an angle 
rad
Angular velocity equation is 
where 
is angular velocity and t is time.
Earth spins at a rate of :
rad/s
Isolating time (t) from angular velocity equation gives:
Answer:
There is not a slope perpendicular to the lie x = -6
Step-by-step explanation:
In this equation, you are given a line, x = -6.
This is in fact a line with an undefined slope. The slope for a perpendicular intersection is the opposite reciprocal of the slope.
Eg. If you have the line y = 2x
The reciprocal is y = 1/2x, the opposite means negative
So the slope that would intersect this line perpendicularly is y = -1/2x.
There is an undefined slope in this, therefore, you cannot find the slope for a line perpendicular to x = -6.
If it were an option, I would choose "no slope"
