Answer:

$165 is the total cost of the first year of Keecia’s gym membership

Step-by-step explanation:

formula for direct proportion : y = kx

x = 50

y = 75

50 = k * 75

k = 75/50

k = 3/2x

substitute y = 60

60 = 3/2x

x = 3/2 * 60

x = 90

$90 + $75 = $165

Answer:

B. Yes.

C. Yes.

Step-by-step explanation:

B. In this, it is saying basically is "2b + b = 3b." Well yes, because 2b + b = 3b. So 3b = 3b? Yes.

C. So same thing. 2b + b = 3b. 3b = 3b. they are equivalent.

Answer:

10√3

Step-by-step explanation:

First we do the prime factorisation of 300:

2²×3×5²

Now we put this into our surd:

[tex]\sqrt{(2^{2})(3)(5^{2}) }[/tex]

Now we split them up:

[tex]\sqrt{2^{2} } \sqrt{3} \sqrt{5^{2} }[/tex]

Now we apply the radical rule of [tex]\sqrt{a^{2} } = a[/tex] if a ≥ 0, for 2 then 5

√2² = 2
√5² = 5

2√3 ×5

Simplify to get

Given,

Side of cube = 12cm

Formulae :

• Total Surface Area of Cube = 6a²

• Volume of Cube = a³

Now Apply,

★ Total Surface Area of Cube

= > 6 × 12 × 12

= > 864 cm²

★ Volume of Cube

= > 12 × 12 × 12

= > 1728 cm³

________________________________________

Step-by-step explanation:

Given :-

To find :-

Solution :-

Volume of cube = a³

Volume = 12³ cm³

Volume = 1728 cm²

Total Surface Area of cube = 6a²

TSA = 6×12² cm²

TSA = 864 cm²

Answer:

$95,231 rounded to the nearest dollar

Step-by-step explanation:

5.8125/100 * $90,000 = $ 5231.25 increase

$5231.25 + $90,000 = $95,231.25

Round to the nearest dollar = $95,231

Answer:

7y+42

Step-by-step explanation:

If I am doing this correctly (so take it with a grain of salt from just waking up) you would multilpy 7 with the expressions in the ( )

So it would be 7*y= 7y

Then 7*6= 42

So it would be 7y+42 I think

Sorry if it is incorrect/ doesn't answer your question. Good luck!

Answer:

[tex]\displaystyle \large{7y+42}[/tex]

Step-by-step explanation:

We are given the expression [tex]\displaystyle \large{(y+6) \cdot 7}[/tex]. Use the distributive property to simplify the expression.

Distributive Property

[tex]\displaystyle \large{a(b+c)=ab+ac}[/tex]

To say it simply, you multiply the outside with the insides. Therefore, from the expression:-

[tex]\displaystyle \large{y \cdot 7 + 6 \cdot 7}[/tex]

Evaluate:-

[tex]\displaystyle \large{\boxed{7y+42}}[/tex]

Step-by-step explanation:

Using the vertex of the quadratic equation, it is found that the maximum profit she can earn is of $106.

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The vertex is given by:

[tex](x_v, y_v)[/tex]

In which:

[tex]x_v = -\frac{b}{2a}[/tex]

[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]

Considering the coefficient a, we have that:

In this problem, her profit is modeled by:

[tex]P(x) = -x^2 + 14x + 57[/tex]

Which is a quadratic equation with coefficients a = -1, b = 14, c = 57, hence, her maximum profit in dollars is given by:

[tex]y_v = -\frac{14^2 - 4(-1)(57)}{4(-1)} = 106[/tex]

Answer:

[tex]\huge\boxed{\boxed{\bf\:4r + 11}}[/tex]

Step-by-step explanation:

Given,

We need to find the value of 2C - D. To solve this, we need to substitute the values of C & D in the expression.  So,

[tex]\tt\:2\:C - D\\\\\sf\:{Substitute \: the \: given \: values}\\\\\tt\:= 2(r + 7) - (-2r + 3)\\\\\sf\:Now, \: follow \: the \: distributive \:property\\\\\tt\:= 2r + 14 + 2r - 3\\\\\sf\:Rearrange\:the\:terms\\\\\tt\:= 2r + 2r + 14 - 3\\\\\sf\:Do \: the \: required \:arithmetic \: operations\\\\=\boxed{ \bf\:4r + 11}[/tex]

[tex]\rule{200}{2}[/tex]

[tex]\rule{200}{2}[/tex]

Hope this helps!

The expression that equals 2C - D is 4r+ 11

The expressions are given as:

C=r+7 and D=-2r+3

The expression 2C - D is calculated as follows:

2C - D = 2 * (r + 7)  - (-2r + 3)

Expand

2C - D = 2r + 14  +2r - 3

Collect like terms

2C - D = 2r +2r+ 14   - 3

Evaluate the like terms

2C - D = 4r+ 11

Hence, the expression that equals 2C - D is 4r+ 11

Answer:

2 - 3x. I hope this helps!!!

Answer:

Step-by-step explanation:

x -4  , 3x-11 , 5x - 18 ,.......

first term = a = x -4

Common difference (d) = second term  - first term

                                =  3x -11 - [ x - 4]

                                = 3x - 11 - x + 4

                                = 3x - x - 11 + 4

                                 = 2x - 7

nth term = a + (n-1)*d

12th term = x - 4 + 11*(2x - 7)

               = x - 4 + 11*2x  - 7 *11

                = x - 4 + 22x - 77

                =x + 22x - 4 - 77

                = 23x - 81
