anthony bought an 8 foot board.He cut off 3/4 of the board to build a shelf,and gave 1/3 of the rest to his brother for an art project.How many inches long was the piece anthony gave to his brother?
Answers
The length he gave to his brother = 8 inch
Further explanation
There are 7 main quantities that have been determined based on international standards, namely:
- 1. Length, meters (m)
- 2. Time, second (s)
- 3. Mass, kilograms (kg)
- 4. Temperature, kelvin (K)
- 5. Light intensity, candela (cd)
- 6. Electric current, ampere (A)
- 7. Amount of substance, mol (m)
The length indicate the distance between two points in a place
The symbol is usually expressed in l, length
Length measurement can be used by several measuring instruments such as ruler / ruler, caliper length, meter, screw micrometer
The main length unit consists of 7 units other than other units of length such as inches, miles, yards, feet:
- Kilometer, km
- Hectometer, hm
- Dekameter, dam
- Meter, m
- Decimeter, dm
- centimeter, cm
- millimeters, mm
Each one unit descends then multiplied by 10, and if one unit increases then divided by 10
English units are the units that were used in England
For the length , the standart from English unit is yard
The conversions between units:
1 m =
a. 1.09361 yard
b. 6.214.10⁻⁴ mile
c. 3.2808 foot
d. 39.3701 inch
Anthony bought an 8 foot board
He cut off 3/4 of the board and gave 1/3 of the rest to his brother
the length of the board he cut :
L cut = 6 foot
Remaining board length :
8 - 6 = 2 foot
From the length of 2 foot , he gave 1/3 to his brother, so the length of board he gave :
we convert this to inch
1 foot = 12 inch
so for become:
The length he gave = 8 inch

So 8 times by 12 = 96 inches
if you have 3/4 of the board used.
3/4= .75
if you were to times 96 by .75 = 72 inches.
So you used 72 inches and you have 24 inches left
now do 1/3= .33
times .33 by 24= 8
8 inches is how long you would give to Anthony's brother.

The shortest perimeter for a fixed area is when you use
the area to make a circle.
The next shortest perimeter for a fixed area is when you
use the area to make a square.
But the longer and skinnier you make it, the longer the perimeter
becomes, without any limit.
Examples:
circle, radius = 3.523 . . area = 39 . perimeter = 22.14
√39 by √39 . . . . . area = 39 . . . . . perimeter = 24.98
6 by 6.5 . . . . . . . area = 39 . . . . . perimeter = 25
5 by 7.8 .. . . . . . . area = 39 . . . . . perimeter = 25.6
4 by 9.75 . .. . . . . area = 39 . . . . . perimeter = 27.5
3 by 13 . . . . . . . . area = 39 . . . . . perimeter = 32
2 by 19.5 . .. . . . . area = 39 . . . . . perimeter = 43
1 by 39 . . . . . . . . area = 39 . . . . . perimeter = 80
0.1 by 390 . . . . . area = 39 . . . . . perimeter = 780.2
0.01 by 3,900 . . area = 39 . . . . . perimeter = 7,800.02
y=width
area=xy
xy=39 ⇒x=39/y
Perimeter of a rectangle=2x+2y
P(x,y)=2x+2y
P(y)=2(39/y)+2y
P(y)=78/y+2y
P(y)=(78+2y²)/y
Therefore ;P(y) will be gratest if y⇒0
We calculate the next limit.
lim y⇒0 (78+2y²)/y=lim y⇒0 (78/y+2y)=∞
For exmple:
y=0.1 ft
then;; x=39/ 0.1=390 ft
P(2*390 ft+2*0.1 ft)=780.2
y=0.001 ft
Then; x=39/0.001=39000 ft
P(2*39000 ft+0.001 ft)=78000,002 ft.
Answer: the greatest perimeter of a rectangle with an area of 39 ft²⇒∞

Find out the cost of the dinner .
To proof
Let us assume that the cost of the dinner be x.
As given
The Silver Town people went to a fancy restaurant after the big event.
Grammy gave the server a $15 tip.
If the tip was 20% of the cost of dinner.
20% is written in the decimal form
= 0.2
Than the equation becomes
x× 0.2 = 15
x =$75
The total cost of the dinner is $75 .
option (C) is correct .
Hence proved

The value of the laptop in 2011 will be $29920
Step-by-step explanation:
Cost of the laptop = $34000
Rate of decrease in value per year = 4%
Total time = 3 years
The Value decrease in 2011 = (34000 x 4 x 3) /100
= $4080
The value of the laptop in 2011 = 34000-4080
= $29920
The value of the laptop in 2011 will be $29920
