Answer:

\large\boxed{\boxed{\boxed{\mathfrak{variable}}}}

Variable is a symbol that represents a quantity in a mathematical expression, as used in many sciences. Variable (research), a logical set of attributes. Variable star, a type of astronomical star.

\large\boxed{\boxed{\boxed{\mathfrak{constant}}}}

A constant, sometimes also called a "mathematical constant," is any well-defined real number which is significantly interesting in some way. A function, equation, etc., is said to "be constant" (or be a constant function) if it always assumes the same value independent of how its parameters are varied.

Find the minimum value of P=5x+6y subject to the following constraints.<br> Please help me!!
Rashid [163]

Answer:

The maximum value of P is 34 and the minimum value of P is 0

Step-by-step explanation:

we have the following constraints

x+y \leq 6 ----> constraint A

2x+3y \leq 16 ----> constraint B

x\geq 0 ----> constraint C

y\geq 0 ----> constraint D

Solve the feasible region by graphing

Using a graphing tool

The vertices of the feasible region are

(0,0),(0,5.33),(2,4),(6,0)

see the  attached figure

To find out the maximum and minimum value of the objective function P, substitute the value of x and the value of y for each of the vertices in the objective function P, and then compare the results

we have

P=5x+6y

For (0,0) ----> P=5(0)+6(0)=0

For (0,5.33) ----> P=5(0)+6(5.33)=31.98

For (2,4) ----> P=5(2)+6(4)=34

For (6,0) ----> P=5(6)+6(0)=30

therefore

The maximum value of P is 34 and the minimum value of P is 0

A water molecule is made up of three Adams. 1/3 of the atoms are oxygen and the remaining Adams are hydrogen. If there are 114 w
motikmotik

The number of hydrogen atoms are 304

<em><u>Solution:</u></em>

Given that a water molecule is made up of three atoms

Number of atoms in water molecule = 3 atoms

1/3 of the atoms are oxygen and the remaining Adams are hydrogen

Number\ of\ oxygen\ atoms = \frac{1}{3}\\\\Number\ of\ hydrogen\ atoms = 3 - \frac{1}{3} = \frac{8}{3}

There are 114 water molecules

8/3 of water molecule is hydrogen

<em><u>Therefore, number of hydrogen atoms is given as:</u></em>

Number\ of\ hydrogen\ atoms = \frac{8}{3} \times 114\\\\Number\ of\ hydrogen\ atoms = 8 \times 38\\\\Number\ of\ hydrogen\ atoms = 304

Thus number of hydrogen atoms are 304

Jake and amber worm at McDonald's they each earn $8 per hour jake works three more hours then amber if jake and amber made a tot
Nadya [2.5K]

Answer:

9 hours

Step-by-step explanation:

Set up the equations: x is the amount of hours Amber worked and y is the hours Jake worked

8x + 8y = 120

y = 3 + x

Substitute the second equation into the first

8x + 8(3+x) = 120

Distribute

8x + 24 + 8x = 120

Combine like-terms

16x + 24 = 120

Subtract 24 on both sides

16x = 96

Divide 16 on both sides

x = 6 (hours Amber worked)

Plug in this x-value into on of the two equations. I will use the second

y = 3 + 6

y = 9

A soccer team played 25 games last season. They won 16 games, lost 5 games, and tied the rest.
goldenfox [79]

Answer:

16% or 4/25

Step-by-step explanation:

16 + 5 = 21

25 - 21 = 4

4/25 = 16%

This is right because 21/25 is 84% and 84% + 16% = 100%
