Answer:
The expression for the perimeter of the rectangle is: 
Step-by-step explanation:
Perimeter of a rectangle:
A rectangle has length l and width w. It's perimeter is given by:
In this question:
So
The expression for the perimeter of the rectangle is:
1 hour = 3600 seconds
3 × 3600 = 10800
<span>10800 yards per hour
</span>
1 mile = 1760 yards
10800 ÷ 1760 = 6.13
6.13 miles per hour
Answer:
m = 2
Step-by-step explanation:
Given:
x = 4
y = 6m - 2
a = 8
b = 5
Required:
Value of m
SOLUTION:
x and y are segments of a chord divided when it intersects another chord that also has segments a and b.
According to the Intersecting chords theorem, 
Thus:
Solve for m
The value of m = 2
Answer:
The angular velocity of Earth is π/12 radians per hour.
The angular velocity of Earth is 2π radians per day.
Step-by-step explanation:
A full circumference of a circle (as the Equator line on Earth) is 2π radians.
Since the planet does a full revolution in 24 hours... that means it makes a full turn in a day.
So, we can see that in a day, the planet rotates 360 degrees... or 2π radians per day!
Now, if you want to find the angular velocity per HOUR... you divide that by 24... so 2π/24 = π/12 radians
So, we can also say it does π/12 radians per hour.
Answer:
110%
Step-by-step explanation:
if each square is a whole, then when one is filled, it's 100% . 10% of the other square is filled so you just add the two.
