Using the numbers 3, 5, and 8, can you write nine proper fractions and nine improper fractions? You may use each number only onc

Iteru [2.4K]

Answer:

9 proper fractions:

3/5,3/8,5/8,3/40,5/24,8/15,3/13,5/11,2/8

9 improper fractions:

8/3,8/5,5/3,24/5,40/3,15/8,11/5,13/3,8/2

Step-by-step explanation:

Proper fraction:

Proper fraction are the fractions in which the numerator is less than the denominator and the value of proper fractions is less than 1.

x/y is proper fraction if x<y and x/y<1

Improper fraction:

Improper fraction are the fractions in which the numerator is greater than the denominator and the value of proper fractions is more than 1.

x/y is improper fraction if x>y and x/y>1

Given numbers: 3,5,8

Making 9 proper and improper fractions with above given numbers with condition to use each number only once within a fraction.

nine proper fractions: (x/y is proper fraction if x<y and x/y<1)

3/5

3/8

5/8

3/(5)(8)= 3/40

5/(3)(8) = 5/24

8/(3)(5) = 8/15

3/(5+8) = 3/13

5/(3+8) = 5/11

(5-3)/8 = 2/8

nine improper fractions: (x/y is improper fraction if x>y and x/y>1)

8/3

8/5

5/3

(8)(3)/5 = 24/5

(8)(5)/3 = 40/3

(5)(3)/8 = 15/8

(3+8)/5 = 11/5

(5+8)/3 = 13/3

8/(5-3) = 8/2 !

Solve this system of equations without graphing and show your reasoning

Drupady [299]

Answer:

x = 1/5

y = 6

Step-by-step explanation:

System:

{5x + y = 7

{20x + 2 = y

First equation:

5x + y = 7 -> y = -5x + 7

Plug into second equation:

20x + 2 = -5x + 7

Subtract 2 from both sides:

20x = -5x + 5

Add 5x to both sides:

25x = 5

Divde both sides by 25:

x = 5/25 -> 1/5

~~~~~~~~~~~~~~~~~~~~~~~~~~~`

Come back to the first equation:

5x + y = 7

Plus in our x:

5(1/5) + y = 7

Multiply:

1 + y = 7

Subtract 1 from both sides:

y = 6

Hope this helps, have a nice day! :D

An object with initial temperature 120° F is submerged in large tank of water whose temperature is

nikitadnepr [17]

Answer:

$F(t)=Ts+(T0-Ts)^{e-0.2t$

Step-by-step explanation:

<u>Newton's law of cooling states </u>

"<em>that the temperature of a body changes at a rate proportional to the difference in temperature between the body and its surroundings"</em>

Newton's Law of Cooling is given by the formula

$F(t)=Ts+(T0-Ts)^{e-kt$

Where

F( t ) is the temperature of the object at a given time t

T s is the surrounding temperature

T 0 is the initial temperature of the object

k is the constant

Given k=0.2

Hence the expression is

$F(t)=Ts+(T0-Ts)^{e-0.2t$
