Answer:

B

Step-by-step explanation:

Let's think about what does the given info mean.

Because of n notebooks, she spent $52

One notebook is $3.25.

So 3.25n = 52

Take it this way if you don't understand

Let's say I spent 4$ on two (2) pens

What's the value of one pen?

We want to find the value of one pen and then multiply it by 2, to get 4$

So we normally would do 4/2

However, to set up an equation, we would create

v (value of one pen) x 2 (pens) = 4$ (cost)

v = 4$/2 = 2$

Answer:

B. 52= 3.25n

Step-by-step explanation:

Unit price multiplied by quantity equals total. So, each notebook cost $3.25 and she buys 'n' notebooks.

She totally spends $52.

In conclusion, 3.25 (unit price × n [quantity]) = 52.

And that is.. 52 = 3.25n.

I'll give more points here is what I need.
Serga [27]

Answer:

The answer to your question is x = 3; y = 3

Step-by-step explanation:

Data

angle = 45°

Opposite side = x

Adjacent side = y

hypotenuse = 3√2

To solve this problem, use trigonometric functions.

1) To find x, use the trigonometric function sine.

              sin Ф = Opposite side / hypotenuse

-Solve for Opposite side (x)

              Opposite side = hypotenuse x sin Ф

-Substitution

              Opposite side = 3√2 sin 45

-Simplification

               Opposite side = 3√2 (1 / √2)

               Opposite side = 3(1)

-Result  

               x = 3

2) To find y use the trigonometric function cosine

               cos Ф = Adjacent side / hypotenuse

-Solve for Adjacent side

                Adjacent side = hypotenuse x cos Ф

-Substitution

                Adjacent side = 3√2 x cos 45

-Simplification

                Adjacent side = 3√2 x (1/√2)

                Adjacent side = 3(1)

-Result

                y = 3

How much is the interest on my loan?
kirill [66]

Answer:  The interest is:  " $ 64 .00 " .

_____________

Step-by-step explanation:

_____________

Take note of the formula:

" Ⅰ = Prt " ;

→ that is:

_____________

→   " Ⅰ = P * r * t " ;

_____________

In which:  

_____________

 " Ⅰ = the interest " ;

 " P = the Principal amount of money " ;

 " r = rate " (expressed as the "decimal form" of the percentage) ;

 " t = time " (in years) ;

_____________

We are given:  

_____________

 P = $400 ;

 r = 0.08 ;  

{<u>Note of interest</u>:  That is " 8% " ; since "8 % "  = "(8/100)" ;

                                                                          = "(8 ÷ 100)"

                                                                          = " 0.08 ".}.

 t = 2 ; {that would represent:  " 2 (two) years".}.

_____________

We are to solve for "Ⅰ" ; the amount of "Ⅰnterest" :

→ To solve for "Ⅰ " ; we plug in our given values; and calculate:

_____________

  →  Ⅰ = P * r * t ;

        = 400 * 0.08 * 2 ;

        = 64 .

_____________

  →  Ⅰ = $ 64.00 .

_____________

Hope this is helpful to you!

Best wishes!
