Answer:

The correct option is;

The domain, r is equivalent to W = {0, 1, 2, 3,...}

Step-by-step explanation:

The cost for each cup of tea sold by the restaurant = $1.50

The cost per tea refill = $0.50

The amount of tea the restaurant brews = 4 refills per customer

The cost of r tea refills C(r) is given as follows;

C(r) = 0.5·r + 1.5

The domain is the set of all whole, W, numbers or the set of all natural numbers including 0

r = W = {0, 1, 2, 3,...}.

Answer: The domain, r is equivalent to W = {0, 1, 2, 3,...}

Answer:

x < 50

Step-by-step explanation:

No more means that it cannot equal 50. Therefore we can remove the 1st two options.

We now have the 3rd option and 4th option to choose from.

The 4th option is incorrect because the inequality is saying that a number is greater than 50.

∴ x < 50 is our answer.

Answer:

C. 5(x-6)=20

Step-by-step explanation:

we can represent the value of x decreased by 6 times 5 as 5(x-6) and then show that that is equal to 20.

Answer:  [C]:  " 5(x - 6) = 20 " .

____________________________________________

Step-by-step explanation:

____________________________________________

Five multiplied (the difference of a 'number' and 6) is "20";

 The "is" refers to an "equal sign";

Let us refer to the unknown number with the variable, "x" ;

Re:  The  "difference" of a "number and 6" ;

Note the "difference" indicates "subtraction:

So;  " (x - 6) ;

"Five times (that difference)" shall be written as:

5*(x - 6) ;

or:  5(x - 6) ;  

We are told that this value "is 20" ; that is:  "equal to 20" ;

So we can rewite the expression; as follows:

    " (5x - 6) = 20 " ;  

Which corresponds to:

   Answer choice:  [C]:  " 5(x - 6) = 20 " .

Answer:

12x³ - 8x² - 54x - 36

Step-by-step explanation:

The polynomial is the product of the factors, that is

(- 4x - 6)(- 3x² + 5x + 6)

Each term in the second factor is multiplied by each term in the first factor, that is

- 4x(- 3x² + 5x + 6) - 6(- 3x² + 5x + 6) ← distribute both parenthesis

= 12x³ - 20x² - 24x + 18x² - 30x - 36 ← collect like terms

= 12x³ - 8x² - 54x - 36

Answer: C

Step-by-step explanation:

The equation represents an exponential function with an initial value of 500 is, [tex]\rm f(x) = 500(2)^x[/tex].

We have to determine, which equation represents an exponential function with an initial value of 500?

According to the question,

An exponential function formula can be defined by,

[tex]\rm f(x) = ab^x[/tex]

Where the input variable is denoted as x occurs as an exponent.

And b is the growth value or decay constant.

The exponential curve depends on the exponential function and it depends on the value of the x.

Therefore,

The equation represents an exponential function with an initial value of 500,

[tex]\rm f(x) = 500(2)^x[/tex]

Where the input variable is denoted as x occurs as an exponent.

And b is 2 the growth value or decay constant.

Hence, The required equation represents an exponential function with an initial value of 500 is, [tex]\rm f(x) = 500(2)^x[/tex].

Answer:

1 1/5

Step-by-step explanation:

3/5 + 3/5 = 6/5 = 5/5 + 1/5 = 1 1/5

Answer:

When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. ... When you divide a negative number by a positive number then the quotient is negative. When you divide a positive number by a negative number then the quotient is also negative.

Step-by-step explanation:

Answer:

x= square root of 2x-1

Step-by-step explanation:

First you move the 3 to the right side of the equation and since it was multiplied; you have to divide it making it 2x-1.

Then, you have to square it so you can get x by itself and since 2x and -1 do not have a square root you just leave it.

Answer:

22 and 1/2

Explanation: 1/5(n-10)=6- 7/2

1/5(n-10)= 6(2)/2- 7/2

1/5(n-10)= 6(2)-7/2- 7/2

1/5(n-10)= 5/2

Multiply both sides by 5

n-10=25/2

Add 10 to both sides

45/2

Turn into a proper fraction which is 22 and 1/2

An expression is a sentence with a minimum of two numbers or variables and at least one math operation such as addition, subtraction, multiplication, or division.

The value of n in the expression 1/5(n-10)=6-3 1/2 is 22.5.

An expression is a sentence with a minimum of two numbers or variables and at least one math operation such as addition, subtraction, multiplication, or division.

We have,

1/5 ( n - 10 ) = 6  - 3 1/2

1/5 ( n - 10 ) = 6 - 7/2

1/5 ( n - 10 ) = ( 12 - 7 ) / 2

1/5 ( n - 10 ) = 5 / 2

Multiplying by 5 on both sides.

n - 10 = 25 / 2

Adding 10 on both sides

n = 25 / 2 + 10

n = ( 25 + 20 ) / 2

n = 45 / 2

n = 22.5

Thus the value of n in the expression 1/5 ( n - 10 ) = 6 - 3 1/2 is 22.5.

Answer:

Step-by-step explanation:

Answer:

y = 21

x = 48

Step-by-step explanation:

for y:

5y - 17 + 2y + 50 = 180

add like terms

7y + 33 = 180

subtract 33 from 180

7y = 147

divide 7 from 147

y = 21

for x:

x + 44 + 7x -248

add like terms

8x - 204 = 180

add 204 to 180

8x = 384

divide 8 from 384

x = 48

now plug it in to find angle measurements:

for y:

5 (21) - 17 = 88°

7 (48) - 248 = 88°

for x:

2 (21) + 50 = 92°

48 + 44 = 92°

Step-by-step explanation:

Volume = length x width x height

since the shape is a cube, volume = 21 x 21 x 21 = 21^3

Step-by-step explanation:

The upstream speed is S / t₁, and the downstream speed is S / t₂.

If we say f is the speed of the fish in calm water, and r is the speed of the river, then:

f − r = S / t₁

f + r = S / t₂

If we say T is the time it takes to cross the river, then the speed perpendicular to the river is ℓ/T, the speed parallel to the river is r, and the overall speed is f.

Using Pythagorean theorem:

f² = (ℓ/T)² + r²

f² − r² = (ℓ/T)²

(f − r) (f + r) = (ℓ/T)²

(S / t₁) (S / t₂) = (ℓ/T)²

S² / (t₁ t₂) = (ℓ/T)²

(t₁ t₂) / S² = (T/ℓ)²

√(t₁ t₂) / S = T/ℓ

T = ℓ√(t₁ t₂) / S

Answer:

x=[tex]\frac{abc}{(bc+ac+ab)}[/tex]

Step-by-step explanation:

First, we need to remove the fractions on the left hand side, which we can do by multiplying each term by the lowest common multiple of the denominators. Since the denominators are all different (a,b and c), then the lowest common multiple is just all three multiplied together: abc

So, our original equation:

[tex]\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=\frac{1}{x}[/tex] now becomes:

[tex]\frac{abc}{a}+\frac{abc}{b}+\frac{abc}{c}=\frac{abc}{x}[/tex]

Now we can simplify the fractions on the right hand side because each numerator can now be divided by its denominator:

[tex]bc+ac+ab=\frac{abc}{x}[/tex]

Now we can just rearrange the equation to solve for x by replacing the x with (bc+ac+ab), because if abc/x= bc+ac+ab, then abc/bc+ac+ab=x, as x and bc+ac+ab multiply to abc:

[tex]x(bc+ac+ab)=abc[/tex]

[tex]x=\frac{abc}{bc+ac+ab}[/tex]
