Answer:
Perimeter.
Step-by-step explanation:
Lee measures around the entire outside of the bulletin board and finds the distance is 32 units.
She is measuring the border of her bulletin board.
The sum of outer covering of any object is called its perimeter. Here, 32 unit shows the perimeter of the bulletin board.
1)volume of the pipeline
The pipeline is a cylinder, therefore;
Volume (cylinder)=πr²h
r=radius
h=height of the cylinder
diameter=6 in*(1 ft / 12 in)=0.5 ft
raius=diameter / 2=0.5 ft / 2=0.25 ft.
height=5280 ft
Volume (pipeline)=π(0.25 ft)²(5280 ft)=330π ft³≈1036.73 ft³.
2) we calculate the number of barrel
1 mile of oil in this pipeline is 330π ft³ of oil.
1 barrel of crude------------------5.61 ft³
x----------------------------------330π ft³
x=(1 barrel*330π ft³) / 5.61 ft³=184.8 barrels
3) we calculate the price.
1 barrel---------------$100
184.8 barrels---------- x
x=(184.8 barrels * $100) / 1 barrel=$18,480
Solution: ≈$18,480
Algebra is made up of quantities and the operations performed on them are addition, subtraction, multiplication and division.
<span>Algebra is a branch of mathematics. It concerns itself with operations on sets of numbers or other elements. The sets of numbers and elements are represented by symbols. Algebra can be seen as a generalisation of arithmetic. Letters are substituted for numbers in Algebra. For example, x + 2x will always equal 3x no matter what values the symbol x represents. The algebraic can also include polynomial functions of one or more of the variables. </span>
Ok so
24=30%
find 100%
24=30%
diivde by 3
8=10%
multiply 10
80=100%
answe ris 80 coins
x=14
Add 4 to both sides to isolate x
