1 rod or long is a column of 10 unit cubes.
10 longs placed side by side, form a flat (with dimensions 10×10)
10 flats, placed on top of each other form a large cube, with dimensions 10×10×10 = 1000 cubes.
-------------------------------------------------------------------------------------------------
each small cube (unit cube) represents the number 1.
thus each long represents 10
each flat represents 100
and each large cube represents 1,000
The number 13,450 can be written as
1*10,000+3*1000+4*100+5*10 using the expanded form.
This means that there are 13 large cubes, 4 flats and 5 longs needed to model the number.
Answer: 13 large cubes, 4 flats, 5 longs
Angle a is 132 degrees
5x-18=3x+42
2x-18=42
2x=60
x=30
then plug 30 in the equation for angle a
5*30-18
150-18
132
First off we need to use the formula S = rΘ
S - is the arc length
Θ - is theta which is the radian measure
r - is the radius
In this problem we need to find r
So, our equation would look like:
S ÷ Θ = r
Before we solve though, we need to convert the degrees to radians:
To convert from degrees to radians, multiply the degrees by π/180° radians:
60 x π/180 = 1.0472
If you input the numbers you get:
10.2 / 1.0472 = 9.740
The radius is 9.7 yards.
The area of a rectangle equals length times height. (A=LH)
A=256.5 L=18
Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)
next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.
So, it is 256.5/18 equaling H
256.5 divided by 18 is... 14.25
That means the height is 14.25 an the length is 18.
the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.
So you have two sides that are 14.25 and two that are 18 meters long.
14.25+14.25+18+18 equals the perimeter then.
So the answer would be... 64.5!
